Det Norske Veritas : Winches type approved and/or
certified by Det norske Veritas (DNV) to meet Norwegian
Max-i time Directorate (NMD) or Norwegian Petroleum
Directorate (NPD) requirements.
In furnishing customers Man-Riding winches, IngersollRand does not warrant the suitability of these winches for
any particular use. It is the owner and user’s responsibility
to determine the suitability of a Man-Riding winch for a
particular application. Further, it is the owner and user’s
responsibility to check and satisfy all local, state, federal
and country requirements pertaining to the lifting and
lowering of persons.
Many agencies require additional redundant safety
devices on winches that IR/SAMIIA does not furnish.
Additional devices are often required to bring the
system up to elevator code standards.
Winches manufactured by IR/SAMIIA as an approved
Man-Riding to DEn and/or NMD/NPD requirements are
furnished with limitations ; approval for use in Man-Riding
applications automatically terminates for any of the
following reasons :
1 - Winch does not meet other applicable codes or
standards.
2 - Winch is not part of an approved system.
3 - Winch is not properly maintained in a new condition
with all parts intact and properly adjusted.
4 - Winch is used in applications not approved by-codes and
regulations, or applications inconsistent with
manufacturer’s operating and maintenance manual.
5 - Changes in DEn or NMD/NPD standards or regulations
after Ingersoll-Rand’s initial shipment of the product.
6 - More than one winch is used to attach to a common
load.
“MAN-LIFTING with this winch is STRICTLY
LIMITED to off-shore marine applications specifically
approved by maritime regulatory bodies. Regulatory
bodies, not manufacturer, have determined suitable use.
DO NOT USE FOR MAN-LIFTING applications not
specifically approved by regulatory bodies.
The use of a winch to lower, lift or suspend personnel
should be permitted only when other means of reaching the
worksite, such as ladders, stairways, aerial (bucket-type)
lifts or scaffolds, arc not feasible because of site conditions.
Be sure to check all regulations, local and country, that
may apply to the use of a winch or winch system for
lifting and lowering people before using a Man-Riding
winch.
7 - The personel platform shall be designed by a properly
qualified engineer competent in this area.

The “Man-riding” winches have been designed and built for
the “oil and offshore” industry and more specifically to
conform with specifications asked for the Norwegian Oil
Ministry and the British Department of Energy.
There arc no norms for the use of “Man-riding” except
those currently demanded by the offshore industry.
Thus it is the responsibility of the user to determine the
adaptability of this material for specific use and to ensure
that it conforms to any rules which may be applicable.
Nomenclature of winch : FEM 4 M (IS0 M ‘7) - Safety
load of stress FXM 2 (IS0 L 2)
This winch is supplied with a Tracability list for the main
parts which are under load together with a DNV “Type
Approval Certificate” S-1024
Construction : the winch has 4 constituent parts designed
for the most difficult tasks :
a) an engine block
b) a brake-control reducer block within the drum
c) a frame constructed mainly of two strutted flanges
d) a drum
Motor : Air motor with two ways of rotation
Reducer : rotary gear system with gears of specially treated
high grade steel mounted on roller bearings.
Brake : disc in large oil bath ensuring constant control of
the load when lowering. It works by decompression thus
ensuring automatic function of the brake in cast of air
failure. This “wet brake” ensures a constant level of braking
and is unaffected by exterior conditions.
Brake : direct on to a large drum ensuring constant control
of the load while lifting or lowering. It works by decompression thus ensuring automatic function of the brake in
case of air failure.
Drum : made of steel with cable fixing by a wedged box.
Frame : made of two strutted flanges.
Air supply to motor : by one hole ø 1/2” BSP located on
the distributor
Control : the winch is controlled by a single lever on the
winch distributor which allows any speed varifation
determined by the operator. This lever returns automatically
to zero thus stopping the load in the event of failure of the
operator.
Chassis skid : made of welded steel with 4 x 18 diameter
fixing holes and 4 x 40 diameter holes for handling.

Prior to installing the winch, carefully inspect it for possible
hipping damage
Owner and users are advised to examine specific, local or
olher regulations, which may apply to a particular type of
use of this product before installing or putting winch to use.
Mounting
1 - If product is to be mounted in one position be sure the
mounting surface is even and of sufficient strength to
handle the rated load and prevent possible binding of the
winch.
2 - Make sure the mounting surface is flat to within l/32
inch (0,8 mm). Shim if necessary
3 - Mounting bolts must be 5/8 in. (16 mm) diameter, Grade
5.8 (classe 8.8) or better. Use self-locking nuts or nuts with
lockwashers.
4 - Torque mounting bolts evenly.
5 - Maintain a fleet angle between the sheave and winch of
no more than 1-1/2 degrees. For every inch of drum length,
the lead sheave must be at least 1.6 feet (0.5 m) from the
drum.
5 - Do not weld to any part of the winch

Wire rope
l Maintain at least 3 wraps of wire rope on the drum at
al1 times.
l Install the wire rope to come off the drum in an
overwind position as indicated on the direction of
rotation tag.
Wire rope selection
Consult a reputable wire rope manufacturer or distributor
for assistance in selecting the appropriate type size of wire
rope and, where necessary, a protective coating. Use a wire
rope which provides an adequate safety factor to handle the
actual working load and meets all applicable industry, trade
association, state and local regulations.
When considering wire rope requirements the actual
working load must include not only the static or dead load
but also loads resulting from acceleration, retardation and
shock load. Consideration must also be given to the size of
the winch wire rope drum, sheaves and method of reeving.
Wire rope diameter for lifting 3/8 in. (10 mm) imperative.
Rigging
Make sure all wire rope blocks, tackle and fastenings have
sufficient safety margin to handle the required load. Do not
allow wire rope to contact sharp edges or make sharp bends
which will cause damage to wire rope, use a sheave. Refer
to wire rope manufacturers handbook for proper sizing, use
and care of wire rope.
Safe Installation Procedures
1 - Do not use wire rope as a ground for welding
2 - Do not attach a welding electrode to winch or wire rope
3 - Never run the wire rope over a sharp edge. Use a
correctly sized sheave.
4 - When a lead sheave is used, it must be aligned with the
center of the drum. The diameter of the lead sheave
must be at least 18 times the diameter of the wire rope.
5 - Always maintain at least three full wraps of wire rope
on the drum.
Air supply
Installing Wire Rope
1 - Cut wire rope lo length in accordance with the wire rope
manufacturers instructions.
2 - Feed the end of the wire rope into the smaller anchor
hole in the wire rope drum and pull through approximately
one fool (0,3 m) of wire rope.
3 - Truck the end of the wire rope back into the wire rope
anchor pocket forming a loop in the wire rope.
4 - Insert the wire rope anchor and pull the wire rope
through the slot tightening the wire rope around the wire
rope anchor.
l Make sure the first
the drum flange.
wrap of wire rope is flush against
5 - PulI the wire rope anchor into position in the drum
anchor pocket.
Wire Rope Spooling
To allow for uneven spooling and decrease in line pull
capacity as the drum fills up, use as short a cable as
practical. To rewind wire rope apply tension to eliminate
slack. This helps achieve level winding and tight spooling.
Safe Wire Rope Handling Procedures
1 - Always use gloves when handling wire rope.
2 - Never USC wire rope which is frayed or kinked.
3 - Never use wire rope as a sling
4 - Always ensure wire rope is correctly spooled and first
layer is tight.
The air supply must be clean and free from moisture.
Air Lines
The inside diameter of the winch air supply lines must not
have be smaller than 5/8” in. (15,9 mm) for flexible lines
and l/2” in. (12,7 mm) for connectors, Before making final
connections, all air supply lines should be purged before
connecting to system inlet. Supply lines should be as short
and straight as installation conditions will permit. Long
transmission lines and excessive use of fittings, elbows,
tees, globe valves, etc, cause a reduction in pressure due to
restrictions and surface friction in the lines.
Air Line lubricator
Always use an line lubricator with these motors. Use a
lubricator having an inlet and outlet at least as large as the
inlet on the motor. Install the lubricator in the air line just
ahead of the motor.
l Lubricator must be located no more than 10 ft. (3m)
from the motor.
The air line lubricator should be replenished daily and set to
provide 5 to 6 drops per minute of GRADE IS068 oil
(minimum viscosity 61,2 Cst at 40°C).
7
Motor
For optimum performance and maximum durability of
parts, operate air motor at 90 PSI at 8 1 scfm (6,3 bar/630
kpa at 2,2 cu.m/min) air pressure and volume. The winch
should be installed as near as possible to the compressor or
air receiver.
Initial Operating Checks
Winches are tested for proper operation prior to leaving the
factory. Before the winch is placed into service the
following initial operating checks should be performed.
a) When First running the motor some light oil should be
injected into the inlet connection to allow good lubrication.
b) When first operating the winch it is recommended that
the motor be driven slowly in both directions for a few
minutes.
The four most important aspects of winch operation are :
1 - Follow all safety instructions when operating the winch.
2 - Allow only qualified people to operate the winch
3 - Subject each winch to a regular inspection and
maintenance procedure
4 - Be aware of the winch capacity and weight of load at all
times.
For winches that have been in storage for a period more
than one month the following start-up procedure is
required.
1 - Pour a small amount of gasoline fluid in the motor inlet
port.
2 - Operate the motor for 10 seconds to flush out any
impurities.
3 - Pour small amount of oil in the motor air inlet port.
4 - Operate the motor for an additional 2 to 3 seconds. The
winch is now ready to work.
“‘As regard manriding winches, it is responsibility of the
owner or user of the winch to determine wether the winch
conform with local regulations for personnel use”
Winch control
The winch spring loaded manual control throttle is mounted
to the air motor.
When viewed from the air motor end move the control
throttle handle to the right (clockwise) to pay out wire rope.
When viewed from the air motor end move the control
throttle handle to the left (counterclockwise) to haul in wire
rope.
To ensure smooth operation of the winch sudden
movements of control valve should be avoided.
Wire rope
Refer the wire rope manufacturers recommendations. At a
minimum observe the following :
1 - Clean with a brush or steam if there is dirt, rock dust or
other foreign material on the surface of the rope
l Do not use an acid-based solvent or other cleaning
fluid.
The reduction gear assembly is filled and shipped with oil
from the factory. Use only high quality lubricants in the
reduction gear assembly such as high grade EP type oil or
their equivalents. Fill the reduction gear assembly until the
working rim is covered.
Oil capacity : 3 litres.
Recommended oil :
GRADE SAE 80 W 90 - Kinematic
Viscosity : 145 mm 2/s at 40°C
2 - Apply a wire rope lubricant or SAE 30W oil.
3 - Brush, drip or spray lubricant weekly, or more
frequently, depending on severity of service.
Reduction Gear Assembly
Replace the oil in the reduction housing at least once every
year. If the winch is used at a normal frequency, the oil in
the reduction housing is suitable for one years operation
without changing. However, when the winch is used at a
high frequency, the oil may need to be changed on a more
frequent basis.
To ensure correct performance, highest efficiency and long
life, it is essential that the lubricating oil be maintained at
the correct level. The recommended grade of oil must be
used at all times since the use of unsuitable oil may result in
excessive temperature rise, loss of efficiency and possible
damage of the gears.
Seals and Bearings
If winch is disassembled, clean all parts thoroughly and
coat bearings and seals with clean grease. Use sufficient
grease to provide a good protective coat.
Storage
For exchange winches or winches that will not be operated
for extended periods pour a small amount oil into the motor
inlet port or supply line. Operate the motor for 2 to 4
seconds to lubricate the motor parts then plug the air inlet
port.
There are two types of inspection, the frequent inspection
performed by the operator while using the winch and
periodic inspections performed by qualified personnel.
Careful inspection on a regular basis will reveal potentially
dangerous conditions while still in the early stages,
allowing corrective action to be taken before the condition
becomes dangerous.
Any deficiency revealed through inspection must be
reported to an appointed person. A determination must be
made as to whether a deficiency constitutes a safety hazard
before resuming operation of the winch.
Records and Reports
Some form of inspection record must be maintained for
each winch, listing all points requiring periodic inspection.
A written report should be made monthly on the condition
of the critical parts of each winch. These reports should be
dated, signed by the person who performed the inspection,
and kept on file where they are readily available to
authorized personnel.
Frequent Inspection
On a winch in continuous service, frequent inspection
should be made at the beginning of each shift. In addition,
visual inspections should be conducted during regular
service for any damage or evidence of malfunction.
OPERATION. Check for visual or abnormal noises
which could indicate a defect. Do not operate a winch
unless the wire rope feeds onto the winch drum
smoothly. If wire rope binds or jumps, clean and
lubricate the wire rope. If problem persists, replace the
wire rope. Do not operate the winch until all defects
have been corrected.

2 - AIR SYSTEM. Check air lines, valves and other
components for leakage. Repair if necessary.
6 - WIRE ROPE
Besides the items in a frequent inspection, inspect for
the following :
3 - WIRE ROPE. Wire rope is a consumable item which
must be replaced when worn. The following list is a
guide to the accepted standards by which wire rope
must be judged and is not presented as a substitute for
an experienced inspector :
a . Damage, such as bird cages, kinking, core protrusion,
crushing, heat damage, and main strand
displacement.
b . Corrosion and nicking
c . Wear of crown wires. Replace at 1/3 wear of any
crown wire.
d . Broken wires or strands, particularly at connections.
Replacement is necessary if one wire is broken at a
connection; six wires broken within one lay ; three
wires broken in one strand within one lay.
e . Lubrication.
Replace wire rope if any doubt exists as to wire rope
serviceability.
4 - WIRE ROPE REEVING. Check reeving and ensure
wire rope is properly secured to the drum.
5 - CONTROLS. See that controls function properly and
return to neutral when released.
Build-up of dirt and corrosion. Clean if necessary.
a-
Loose or damaged end connection. Replace if loose
b-

FOUNDATION. Check for the continued ability to
7
sustain the imposed loads.
Periodic Inspection
According to ANSI/ASME B30.7, frequency of periodic
inspection depends on the severity of usage : NORMAL,
yearly; HEAVY, semiannually; SEVERE, quarterly.
Disassembly may be required for HEAVY or SEVERE
usage. Keep accumulative records of periodic inspections to
provide a basis for continuing evaluation. Inspect all the
items in a frequent inspection plus the following:
1 - FASTESERS. Check, capscrew, nuts, pins and other
fasteners on winch and air system. Replace if missing
and tighten or secure if loose.
2 - ALL COMPONENTS. Inspect for wear, damage,
distortion, deformation and cleanliness. If external
evidence indicates the need, disassemble. Check gears,
shafts, bearings, springs and covers. Replace worn or
damaged parts. Clean, lubricate and reassemble.
3 - DRUM AND SHEAVES. Check for damage or
excessive wear. Replace if necessary.
4 - BRAKE. Perform functional load test on winch. Check
ability of the brake to hold rated load.
Winches Not in Regular Use
A winch which has been idle for a period of one month or
more, but less than six months, shall be given an inspection
conforming with the requirements of “Frequent Inspection”
before being placed into service.
A winch which has been idle for a period of over six
months shall be given a complete inspection conforming
with the requirements of “Periodic Inspection”. Standby
winches shall be inspected at least semiannually in
accordance with the requirements of “Frequent Inspection”.
If adnormal operating conditions apply, winches may
require a more frequent inspection.
5 - LABELS AND TAGS. Check for presence and
legibility. Replace if necessary.
