a Safety Lock.

Q: How many Safety Lock positions does my Lift have?

A: Eleven, spaced every 4 inches / 101.5 mm.

Q: Does the Lift have a Front and Rear?

A: Yes and no. Because you can drive onto a two-post Lift from either opening, there is technically

no Front and Rear. However, most garages have an Approach side and a Wall side, so in that
case, the Wall side is the Front and the Approach side is the Rear.

Q: How do I know where to put the Adapters when I want to raise a Vehicle?

A: The Vehicle needs to be balanced, so you must put the Adapters (sometimes called Pads) so that

they contact the manufacturer’s recommended Lifting Points.

Components

GP-7 Series Lift components include:

• Powerside Post. The Powerside Post holds the Power Unit, the Safety Lock Release Handle,
the Lowering Handle, and the Power Disconnect Switch. The Powerside Post must go under the
Cylinder end of the Top Trough.

• Offside Post. The other Post. The Offside Post goes under the Cables end of the Top Trough.

• Power Unit. Provides hydraulic power to the Lift. Connects to a 220 VAC power source. Includes
the button that raises the Lift and a Hydraulic Fluid reservoir that must be filled

• Safety Locks. Hold the Lift Arms while they are raised. Multiple Safety Locks let you select the
best Lift Arm height for your needs.

engaged on a Safety Lock

• Safety Lock Release Handle. Releases the Lift from its current Safety Lock. Used as part of
the lowering process.

• Lowering Handle. Lowers a Vehicle from a raised position when used with the Safety Lock
Release Handle.

• Lift Pads. Rubber pads that contact the Lifting Points of the Vehicles you raise. Also included
with your Lift are three sets of extensions (short, medium, tall) that can be used with the Lift Pads.

• Lift Arms. Extendable steel arms that attach to the Lift Heads. Lift Arms hold the Lift Pads; after a
Vehicle is moved into place, the Lift Arms are moved so that the rubber pads contact the Lifting
points on the Vehicle. The Lift Arms are one of the components that actually holds a Vehicle up.

• Lift Heads. Sometimes called carriages. Lift Heads move up and down in the Posts. They
connect to the Lift Arms, so when the Lift Heads move up, the Lift Arms (and anything on them)
also move up, thus raising the Vehicle.

• Top Trough. The beam across the top of the Lift; it supports the Lift’s structure and holds the
Hydraulic Cylinder and the Lifting Cables.

• Trip Stop Tube. Located on the underside of the Top Trough, the Trip Stop Tube stops upward
movement of the Lift. If you are raising a Vehicle and it hits the Trip Stop Tube, the Lift immediately
stops moving up.

• Power Disconnect Switch. Immediately interrupts main electrical power to the Lift. Used for
electrical circuit faults, emergency situations, or when Lift is undergoing service or maintenance.

• Thermal Disconnect Switch. Overload device that makes sure the equipment shuts down if
there is an overload or an overheated motor. The Lift’s motor has no thermal overload protection.

Unloading and Unpacking

Once the components are unloaded, they are your responsibility to move around. The Lift includes a
number of heavy pieces, so the closer you unload them to the installation location, the better off you
will be.

⚠ WARNING Some Lift components are very heavy; if handled incorrectly, they can damage

materials like tile, sandstone, and brick. Try to handle the Lift components just
twice: once when delivered and once when moved into position. You must have a
Forklift or Shop Crane to move some of the Lift components into position. Use care
when moving them around.

About Embedment

Anchor Bolts (also called Wedge Anchors) get their holding strength from how far down into the Hole
the Anchor Bolt is installed (called embedment) and how forcefully the Expansion Sleeve presses into
the Concrete (based on how much torque is applied).

To get enough embedment, you have to understand Effective Embedment, which means the location
in the Hole where the Expansion Sleeve presses into the Concrete. This is where the Anchor Bolts
create holding strength; the further down into the Hole, the greater the holding strength.

(The technical definition of Effective Embedment is the distance from the surface of the base material
to the deepest point at which the load is transferred to the base material; the “base material” in our
case being the Concrete into which the Anchor Bolts are being installed.)

Some people confuse Effective Embedment with Nominal Embedment, which is how far down into the
Hole the bottom of the Anchor Bolt is.

As shown below, the two are not the same. Nominal Embedment is
to the base material, Effective Embedment is.

Anchor Bolt specifications are:

• Length: 6.3 inches / 160 mm

• Diameter: .75 inch / 19 mm

• Anchor torque: 85 – 95 pound feet (never less

than 80 or more than 110)

• Effective embedment: 3.25 inches / 82.5 mm

or more

⚠ WARNING Your Concrete and Anchor Bolts must meet these specifications. Only install your

Lift on a Concrete surface. If you install a Lift on asphalt or any other surface, or
your Concrete or Anchor bolts do not meet these specifications, it could lead to

prescribed by the latest version of the American National Standard “Automotive Lifts – Safety
Requirements for Construction, Testing, and Validation” ANSI/ALI ALCTV.

⚠ WARNING Use only the ALI-certified Anchor Bolts that came with your Lift. If you use

components from a different source, you void your warranty and compromise the
safety of everyone who installs or uses the Lift.

Lift buyers are responsible for conforming to all regional, structural, and seismic anchoring
requirements specified by any other agencies and/or codes, such as the Uniform Building Code and/or
International Building Code.

To install the Posts:

1. Using a Forklift or other appropriate lifting device, move the Posts to the Chalk Line Guides.

2. Stand up each Post, one at a time, and move the appropriate corners into the corners created by
the Chalk Line Guides.

3. Double check your measurements against the Specifications for your Lift model:

 Distance from back of one base plate to back of other base plate: Width Overall value

 Distance from inside of one Post to inside of other Post: Inside Posts value

4. Using the Base Plates as guides, drill each hole 4 inches / 101 mm deep.

Do not drill all the way through the Concrete; if you punch
completely through the slab, you could compromise the holding
strength of the Anchor Bolts.

Go in straight; do not let the drill wobble.

Use a carbide bit (conforming to ANSI B212.15).

The diameter of the drill bit must be the same as the diameter of
the Anchor Bolt. So if you are using a ¾ inch diameter Anchor
Bolt, for example, use a ¾ inch diameter drill bit.

is less holding strength.

6. Make sure the Washer and Nut are in place, then insert the Anchor Bolt into the hole.

Do not torque the Anchor Bolts at this point

Installing the Top Trough and doing final leveling (both of which are done later in the installation
process) are both easier if there is a little bit of play in the Posts.

If you torque the Anchor Bolts now, there will not be any play in the Posts, making it more difficult
to install the Top Trough and do final leveling.

Routing the Lifting Cables

The Lifting cables move the Lift Heads and Lift Arms up and down.

To route the Lifting cables:

1. Extend the Cylinder Rod until the Pull Block Sheave Pin lines up with the Access Hole; this can be
done by carefully pulling the Cylinder Rod by hand or carefully using an air gun.

⚠ CAUTION Be careful not to damage the Cylinder Rod when extending it. Do not exceed 50

PSI if using an air gun. If Cylinder Rod is not extending, stop and use a cable puller
or other pulling device. Keep hands clear of pinch points.

This drawing is looking down on the Top Trough from above.

GrandPrix Two-Post Lifts 22 P/N 5900209 — Rev. E1 — February 2021

Tip BendPak recommends installing the two Short Cables (which go on the inner sheaves)

first, then proceed to the two longer cables (which go on the outer sheaves).

2. Put the Button End of first Short Cable into position at the Tie Plate.

The following drawing is a side view of how a Short Cable gets routed over the sheaves.

3. Route the Short Cable under the bottom of the Cylinder sheave and then over the top of it, over
the top of the Offside end sheave, and down through the hole in the bottom of the Top Trough.

4. Do the same thing for the second short cable.

Make sure to put the Button End of the second Short Cable on the other side of the Tie Plate from
the Button End of the first Short Cable.

5. Put the Button End of the first Long Cable into position at the Tie Plate, on the outside of either of
the two Short Cables (it does not matter which one you do first).

The following drawing is a side view of how the Long Cables get routed over the sheaves on the
Offside end of the Top Trough.

6. Once the Button End is in place, route each Long Cable like this:

• Under the bottom of the Cylinder side sheave and then over the top of it.

• Over the top of the Offside end sheave and then under the bottom of it.

• Past the Cylinder side sheave (without touching it), towards the two-groove sheave on the

Powerside end.

• Over the two-groove sheave on the Powerside end and then down into the appropriate hole in

the bottom of the Top Trough.

GrandPrix Two-Post Lifts 23 P/N 5900209 — Rev. E1 — February 2021

The following drawing is a side view of how the Long Cables get routed over the two-groove
sheave and down into the hole on the Powerside end of the Top Trough.

Make sure the all cables sit in the grooves and not on either edge of the sheave assembly.

7. Secure the cables with the top of the Tie Plate using a flat head and hex head bolts.

The following drawing shows how the Button ends and cables should appear just after you secure
the top of the Tie Plate into position.

Important: Make sure the cables are carefully aligned in their sheaves; you want to avoid as

much contact as possible between the cable and the sheaves while the Lift is in
motion. This makes the Lift move more smoothly and extends the life of the cables
and the sheaves.

8. The ends of the four cables will be hanging over the ends of the Top Trough.

⚠ CAUTION Do not step on or trip over the four Lifting cables while the Top Trough remains

near the ground. They are a hazard until the Top Trough is put into position.

GrandPrix Two-Post Lifts 24 P/N 5900209 — Rev. E1 — February 2021

Routing the Safety Cable

The Safety Cable connects to the safety mechanism on the Offside Post, goes over the Safety Sheave
in the Offside end of the Top Trough, travels over the Lifting Cables in the Top Trough, goes over the
Safety Sheave in the Powerside end of the Top Trough, and then goes down to the safety mechanism
on the Powerside Post and eventually to the Safety Lock Release Handle.

After being fully set up, the Safety Cable and the Safety Lock Release Handle are used to release the
safety locks, allowing the Lift to be lowered.

About Hydraulic Fluid Contamination

IMPORTANT! PLEASE READ NOW

Hydraulic Fluid Contamination poses a serious issue for your Lift

water, dirt, thread seal tape, and other debris can get into the Hydraulic Hoses and Fittings on the Lift,
making your new Lift inoperable.

Your Lift is shipped with clean components; however, BendPak strongly recommends that you take
secondary precautions and clean all Hydraulic Hoses and Fittings prior to making connections. It is
better and less costly to take these extra steps now so that you do not need to take your Lift out of
service later to fix issues that could have been prevented.

There are several ways to clean Hydraulic Hoses and Fittings:

• Compressed Air. Use an air compressor to blow out contaminants from each Hydraulic Hose
and Fitting prior to installation. Clean, dry air is preferred. Wear ANSI-approved eye protection
(safety glasses, goggles, or face shield) when using compressed air for cleaning. Never point an air
hose nozzle at any part of your body or at a person.

• Fluid Flushing. As long as the Hydraulic Fluid is clean and compatible with the system fluid, you
can flush Hoses and Fittings to create turbulent flow and remove particulates. Always ensure that
the fluid itself is contaminant-free.

Some additional steps that will help keep the Hydraulic Fluid clean:

• Remove old thread seal tape. Some ports on the Hydraulic Cylinders are shipped with
temporary plugs secured with thread seal tape, so make sure to thoroughly remove any leftover
thread seal tape; otherwise, it could get into the Hydraulic System.

• Use a liquid thread sealant only. Liquid thread sealant (Loctite™ 5452 or similar) is
recommended.
recommended for NPT threads, but not necessary for JIC and O-ring (ORB) threads.

• Always use clean equipment. If you use a dirty bucket or funnel to transfer Fluid into the
Reservoir, the contaminants will get into the Fluid. When using cleaning rags, use a lint-free rag.

• Proper storage. Keep the Hydraulic Fluid sealed in its container until ready for use; store the
Fluid in a clean, dry, and cool area.

• Cover the Hoses and Fittings. Before installation, do not leave the ends of the Fittings
exposed; the same applies for the Hydraulic Hoses. Keep the Hydraulic Hoses and Fittings capped
and in a clean area until ready for use.

• Filter the new Hydraulic Fluid. Just because it is new does not necessarily mean it is clean.
Use an offline filtration cart or kidney loop system to make sure the Hydraulic Fluid is clean before
being transferred into the Hydraulic Fluid Reservoir (even using a heavy duty nylon mesh screen is
better than trusting what is left at the bottom of the barrel).

• Avoid mixing different types of Hydraulic Fluid. If Hydraulic Fluid needs to be replaced,
make sure to flush the Hydraulic System of the old Hydraulic Fluid before you add the replacement
Fluid; do not mix the two together.

Do not use thread seal tape on any fitting

. Liquid thread sealant is

; contaminants such as

GrandPrix Two-Post Lifts 33 P/N 5900209 — Rev. E1 — February 2021

About Thread Sealants

We recommend using a Liquid Thread Sealant (like Loctite™ 5452 or similar PTFE Thread Sealant) to
seal the Hydraulic components on your Lift.

Liquid Thread Sealant lubricates and fills the gaps between the Fitting threads, and leaves no particles
that could contaminate the Hydraulic Fluid. Thread Sealant can be used with most Hydraulic Fittings,
although you probably only need it for Hydraulic Fittings with NPT connectors.

To apply Thread Sealant:

1. Make sure the Fittings and connectors you are going to use are clean and dry.

If you are adding Thread Sealant to a Fitting or connector that has already been used with a
different Sealant, use a wire brush to thoroughly remove the old Sealant before adding more.

2. Apply a small amount of Thread Sealant to the first four threads of the Fitting.

⚠ WARNING Make sure to wear the proper protective equipment when using Thread Sealant.

You only need a small amount because the Sealant will spread to the other threads as the Fitting is
tightened into place.

If you put too much, the excess liquid will be pushed out when the Fitting is tightened; use a rag to
wipe the excess.

3. Tighten the Fitting into the connector; do

4. Allow the manufacturer-recommended curing time before pressurizing the system.

Installing the Hydraulic and Return Line

Two Hydraulic Hoses run along the outside of the Powerside Post. They connect to Ports on the
Power Unit on one end and to the Valve Block (in the Top Trough) on the other end.

For this procedure, you will need:

• Two Hydraulic Hoses (lengths vary depending on model). One Hose functions as the Hydraulic
Line, the other Hose is used for the Return Line.

• Two JIC x NPT Nipple Fittings (P/N 5550147)

• One JIC x NPT Elbow Fitting (P/N 5550106).

• One JIC x ORB Elbow Fitting (P/N 5550103).

To install the Hydraulic Hoses:

1. Prepare the Hydraulic components using the information in Hydraulic Fluid Contamination.

2. Remove the Shipping Plugs from the two Hydraulic Ports on the Cylinder Block.

3. Attach the NPT end of the Nipple Fitting to each Port on the Cylinder Block; use Liquid Thread
Sealant on the NPT threads only.

4. Attach the Hydraulic Hoses to the JIC ends of the Nipple Fittings you just installed.

The following graphic shows the Hydraulic Line and Return Line in place.

Installing the Lift Arms

Lift Arms are what actually raise Vehicles off the ground.

Your Lift has four arms:

• Two Straight Arms: install them at the rear of the Lift.

• Two Angled Arms: install them at the front of the Lift.

To install the Lift arms:

1. Raise a Lift Head two to three inches off the ground.

2. Move a Lift Arm into place in the Lift Head.

3. Install a Lift Head Pin through the Lift Head and the Lift Arm, then push a Snap Ring into its
grooves on the bottom of the Lift Head Pin.

Make sure an Angled Arm Spacer is in place on top of each Angled Lift Arm; they are not
necessary for Straight Lift Arms.

4. Repeat Steps 2 and 3 for each of the other Lift Arms.

⚠ DANGER The gears must be positioned and adjusted properly. Confirm proper gear

engagement prior to operation of the Lift. Periodic inspection and adjustment is also
required. Failure to properly inspect and adjust the arm restraint gears on all four
arms can result in damage to the Vehicle, injury, or even death.

5. Install the Arm Gear Ring bolts and adjust the Arm Gear Rings so that the teeth on the gear ring
mesh fully and smoothly with the teeth on the Arm Restraint Gear.

Important: Arm Gear Rings have a Left or Right orientation, based on looking at the Post from

the inside of the Lift, as shown above. You must correctly orient the arms.

6. Tighten the Gear Ring bolts.

7. Verify the operation of the Arm restraints by pulling up on the Key Ring of the Arm Restraint Pin.
Pivot the arms back and forth and test the operation of the Arm Restraint Pin in various positions.

Make sure the Lift Arms do not move when a force of approximately 100 pounds or less is applied
laterally to the fully extended arms.

8. Adjust the Gear Ring on each arm as necessary to ensure smooth operation and solid
engagement of all four Arm Restraint Pin Assemblies with the Arm Restraint Gear Ring.

⚠ WARNING Each arm restraint assembly must be inspected and adjusted before you use the

Lift each and every time. Do not operate the Lift if any of the four arm restraint
systems are not functioning properly. Replace any broken components or

Contact the Electrician

As mentioned previously, there are certain installation tasks that

⚠ DANGER All wiring

not a certified Electrician attempts these tasks, they could damage the Lift or be
electrocuted, resulting in serious injury or even death.

The Electrician needs to:

• Attach a Power Cable with an appropriate plug. The Power Unit needs to connect to an
appropriate power source; it comes with a pigtail coming out of the Electrical Box, but without a
longer power cable or a plug attached. The Electrician needs to remove the pigtail and then
connect a power cable with a plug that is appropriate for your location (220 VAC plugs are different
in different parts of the world).

• Wire the Microswitch. This is generally done at the same time as the Electrician wires the
power source to the Power Unit, as the Microswitch wiring goes between the incoming power
source and the Electrical Box on the Power Unit. The Microswitch wiring is provided with the Lift.

• Install a Power Disconnect Switch. Ensures you can quickly and completely interrupt
electrical power to the Lift in the event of an electrical circuit fault, emergency situation, or when
equipment is undergoing service or maintenance. You must put it within sight and easy reach of
the Lift operator. Refer to Install a Power Disconnect Switch for more information.

• Install a Thermal Disconnect Switch. Ensures the equipment shuts down in the event of an
overload or an overheated motor. Refer to Install a Thermal Disconnect Switch for more
information.

Installing a Power Disconnect Switch

WARNING

A Power Disconnect Switch is
equipment.

A Power Disconnect Switch is a National Electrical Code
(NEC) requirement. They are designed to interrupt main
electrical power in the event of an electrical circuit fault,
emergency situation, or when equipment is undergoing
service or maintenance.

Make sure to install a Power Disconnect Switch that is
properly rated for the incoming power source.

Your Power Disconnect Switch must be readily
accessible and installed so that it is in easy reach of the
operator or in their line of sight. The Power Disconnect
Switch must be clearly marked to indicate its purpose.

The figure to the right shows a toggle-style Power
Disconnect Switch located between the Lift’s power
source and its Power Unit. A quick flip of the switch
immediately cuts power to the Lift.

In the case of the GP-7, the location directly above the
Power Unit is being used by the Lowering Handle, so
your Electrician may want to move the Power
Disconnect Switch location up a little.

Final Leveling

Before operating your Lift, you need to make sure that both the Lift posts and the Lift arms are level:

• Lift Posts: The Posts

To make sure the Posts are level, measure the distance between the two Posts six inches below
the Top Trough and one foot off the ground (you will need to move the Lift Arms out of the way).
The two measurements (A and B in the drawing below) must be the same.

If the Posts are not level, shim them as required.

• Lift Arms: When the Lift Posts are level, make sure the Lift Arms are level as well. To make sure
they are level, raise them to the first locking position and put a level on the pads.

GrandPrix Two-Post Lifts 45 P/N 5900209 — Rev. E1 — February 2021

Lubricate the Lift

BendPak recommends lubricating the following locations on the Lift before starting normal operation
and on a monthly basis afterwards, to keep your Lift working better and longer:

• The four inside corners of both Posts (which is where the Slide Blocks slide)

• The pins of the Microswitch Sheave and the Safety Sheaves

We recommend using white lithium grease or light axle grease as the lubricant.

Bleeding the Hydraulic Cylinder

Bleeding the Hydraulic Cylinder removes excess air from the cylinder. Air in the Hydraulic Cylinder can
cause the Lift to move erratically or make odd noises.

The Hydraulic Cylinder is self-bleeding, which means you just have to use the Lift a few times and
excess air will get worked out of the Hydraulic System.

To bleed the Hydraulic Cylinder:

1. Raise and lower the Lift four or five times;

Refer to Operation for raising and lowering instructions.

2. Check the Hydraulic Fluid level; it may be down as a result of using the Hydraulic System.

Add more Hydraulic Fluid if necessary. Lift must be fully lowered to change the Hydraulic Fluid.

3. Raise the Lift to full rise and run the motor for approximately three seconds after the Lift stops.

This places pressure on the Hydraulic System.

4. Stop and check all fittings and hose connections; tighten or reseal if required.

5. Lower the Lift back to the ground.

GrandPrix Two-Post Lifts 46 P/N 5900209 — Rev. E1 — February 2021

Perform an Operational Test

Before putting your Lift into normal operation, we recommend raising and lowering it several times with
a typical Vehicle on the Lift. This will help you get a feel for how to operate the controls and help get
any residual air out of the Hydraulic System (sometimes called “bleeding” the system).

⚠ DANGER Automotive Lifts are dangerous tools when used by inexperienced, impaired, or

distracted technicians. When you even hear the words “automotive lift,” your brain
should automatically register the fact that lifting a vehicle is a serious endeavor with
life-threatening risks if mandatory lifting precautions are ignored.

During the Operational Test, check for proper installation and operation. Do not raise any additional
Vehicles until a thorough Operational Test has been done with a typical Vehicle.

⚠ WARNING Never raise a Vehicle whose weight exceeds the rated capacity of the Lift. Do not

leave the controls until the Lift is engaged on its Safety Locks. Only trained
personnel should raise or lower the Lift.

To perform an Operational Test:

1. Follow the instructions in Raising the Lift and Lowering the Lift to safely raise and lower a
Vehicle on the Lift.

⚠ WARNING Be sure to follow the instructions carefully when it comes to contacting the

manufacturer’s recommended Lifting Points on the underside of the Vehicle. If you
do not, the Vehicle could become unstable and fall, which could damage the
Vehicle, damage the Lift, and injure or even kill anyone under the Vehicle.

2. Adjust the Lift Arms under the Vehicle so the Adapters are

Vehicle to the ground. When the Lift is on the ground, remove it from service,
disconnect it from power, and make arrangements to get it fixed.

Only measure fluid levels when the Lift is fully lowered. Otherwise, some of the fluid will be in the
hoses and the cylinder, and thus throw off your ‘full’ or ‘low’ assessment.

• Monthly: Check cable connections, bolts, and pins for proper mounting and torque.

• Monthly: Check arm adjusting locks for proper operation.

• Monthly: Make sure all pivot arm pins are properly secure.

• Every two months: Check all Anchor Bolts to make sure they are correctly torqued. If they are
not, torque them.

• Every three months: Check the lubrication of the Wire Rope.

• Every three to five years or as needed. Carefully check the Lifting Cables every three to five
years, or immediately if there are signs of damage or extreme wear. See Wire Rope Inspection

and Maintenance for additional information.

⚠ WARNING: Do not operate your Lift if you find maintenance issues; instead, remove it from

service, then contact your dealer, visit bendpak.com/support, email

[e-mail], or call [phone].

GrandPrix Two-Post Lifts 53 P/N 5900209 — Rev. E1 — February 2021

Wire Rope Inspection and Maintenance

Your Lift’s Cables, which are wire rope, should be inspected regularly:

• Wire rope should be replaced when there are visible signs of damage or extreme wear. Do not use
the Lift if it has damaged or worn Cables;

• Wire rope should be maintained in a well-lubricated condition at all times.

Wire rope is only fully protected when each wire strand is lubricated both internally and externally.
Excessive wear shortens the life of wire rope. Use a wire-rope lubricant that penetrates to the core
of the rope and provides long-term lubrication between each individual strand, such as 90-WT
gear oil or ALMASOL® Wire Rope Lubricant. To make sure that the inner layers of the rope remain
well lubricated, lubrication should be done at least every three months during normal operation.

take it out of service!

• All Sheaves and guide rollers that contact moving wire rope should be given regular visual checks
for surface wear and lubricated to make sure they run freely. This should be done every three
months during normal operation.

For all sheave axles, use standard wheel bearing grease. For all Sheaves and/or guide rollers, use
90-WT gear oil or a similar heavy lubricant, applied by any method including pump/spray
dispensing, brush, hand, or swabbing.

• How often should you inspect?

Wire rope should be visually inspected at least once each day when in use, as suggested by
American Petroleum Institute’s Recommended Practice 54 guidelines. Any wire rope that meets
the criteria for removal must be immediately replaced.

• When should you replace wire rope due to broken wires?

Wire rope should be removed from service if you see six randomly distributed broken wires within
any one lay length or three broken wires in one strand within one lay length.

• Are there other reasons to replace your wire rope?

Yes. Corrosion that pits the wires and/or connectors, evidence of kinking, crushing, cutting, bird­caging, or a popped core, wear that exceeds 10% of a wire’s original diameter, or heat damage.

• How do you find broken wires?

a. Relax your rope to a stationary position and move the pick-up points off the Sheaves. Clean

the surface of the rope with a cloth — a wire brush, if necessary — so you can see any breaks.

b. Flex the rope to expose any broken wires hidden in the valleys between the strands.

c. Visually check for any broken wires. One way to check for crown breaks is to run a cloth along

the rope to check for possible snags.

d. With an awl, probe between wires and strands and raise any wires that appear loose.
