INSTALLATION INSTRUCTIONS – EM1-200 & -500, EHTT, EHTT-L

Review this entire page before installing the tilting table.
Consult the factory in the event there are any questions or problems at the time of installation, or for

information regarding optional features not covered by the owner’s manual.

The tilting table must be removed from the shipping wood and securely anchored to the floor before use! The

EM1-500 platform must be tilted to the 90° position, and support ed if necessary, before removing the shipping wood.

• Modifications or additions to the tilting table without prior manufacturer’s authorization may void the unit’s
warranty. The addition of ancillary equipment to the platform may necessitate that its load capacity be reduced.

• The installation must be made so that it complies with all the regulations applicable to the machine and its
location. The end-user must verify that the supplied equipment is installed so it will be suited to the environment
in which it will be used.

• Installation must be performed by suitably trained personnel with access to the appropriate equipment. The
electrical aspects of the installation should be performed by an electrician.

---------------------------------------------------------------------------------------

For a typical installation of a standard tilting table you will need the following:

1. A fork truck or hoisting means to unload the tilting table from the freight truck and set it into place.

2. A smooth, level, and adequately strong concrete surface on which to mount and operate the tilting table.

3. Concrete anchors, a masonry drill, a masonry bit, hand tools, grout, and steel shims. Consult the building’s
architect or facility engineer to determine the best size and type of hardware with which to anchor the machine to
the floor.

• Units designed to be portable do not need to be anchored to the floor.

4. A power supply circuit and electrical disconnect matching the motor voltage and current requirem ents. Refer to
the machine’s dataplate, to the labels on the control enclosure, and to the electrical section in this manual for
more information. The end-user is responsible for supplying the branch circuit’s required ground fault and short­circuit protection. (Motor overload protection is provided by a thermostat built into the motor.)

---------------------------------------

To install a standard non-portable tilting table:

1. Remove the shipping boards from underneath the tilter’s frame.

Caution: On EM1-500’s, tilt the platform down fully (the cylinder will be extended) before removing the boards.
Otherwise, the unit could be top-heavy and tip over unexpectedly.

2. Move the tilter into place with a fork truck having at least a 2,000 lb capacity.

3. Temporarily connect the power supply to the pigtail cord supplied with the tilting table, and tilt the platform to its
maximum angle so that the control enclosure is accessible.

o If the platform must be tilted without first having the proper power supply connected, support under the backstop

side of the platform by either attaching rigging from a crane or hoist, or insert ing a lift truck’s forks under the
platform. Carefully unpin one end of the cylinder(s) and allow the platform to tilt to its maximum angle. Once the
power supply is connected, press the LOWER pushbutton to allow the cylinders to retract. (Single-acting cylinders
must be manually compressed in order to retract.) Finally, reinstall the cylinder pin and its hardware.

Anchor the frame to the floor through each anchoring bracket located at the frame’s perimeter using appropriate

4.
concrete anchors.

5. Make permanent connection to the power supply, using an appropriate wiring method.

6. Operate the tilting table through several full raise and lower cycles. Verify that the limit switch(es) functions
properly.

7. Check the hydraulic oil level. It should be within 1” of the reservoir’s fill hole with the cylinders retracted. If oil
is needed, use an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F (ISO 32 at 40°C) or a non­synthetic automatic transmission fluid.

8. Clean up any debris or spilled oil, and verify that all of the warning and safety labels are in good condition.

OPERATION INSTRUCTIONS – EM1-200 & -500, EHTT, EHTT-L

o Consult ANSI MH29.2 - 2000, Safety Requirements for Industrial Tilters, Section 12, for the owner’s / user’s

responsibilities regarding the operation, care, and maintenanc e of this machine.

o Ensure that all employees involved in the operation of this machine understand and follow these instructions!

The standard tilt table models are suitable for use indoors in most industrial locations and many c om mercial

locations. They are intended to be used to tilt stable, non-hazardous loads and containers with rigid sides having a size
or footprint appropriate for the tilter’s platform and backstop dimensions.

Loading:

The load rating, in pounds, is shown on the machine dataplate located on the front side (opposite the backstop) of the
platform. It indicates the net capacity of the machine with a static load that is centered and evenly distributed on the
platform, and having a vertical center of gravity not more than 20” above the platform surface and a horizontal center
of gravity not more than 20” from the backstop.

For applications involving dynamic loads, such as for use with conveyor systems which create side or end edge loading
of the platform, consult the factory.

Do not exceed a rate of one foot per second when moving loads onto or across the platform.
Always center the load against the backstop of the platform to prevent sudden load shifting when the platform is

tilted.
Note: The addition of any ancillary equipment to the platform by third parties must be taken into account when

determining the maximum working load to be placed on the platform.
Warning: Do not exceed the tilting table’s load ratings. Injury to personnel or permanent damage to the structure

could result from exceeding the listed capacity.

Operation:

Warning: Keep all personnel clear of the machine when it is in operation. Be certain no part of any person or o bject is
under any part of the platform before lowering the unit.

Caution: Always carefully watch the container and any load in it when it is in operation.

The tilting table is furnished with either a constant-pressure (dead-man style) pushbutton (standard), or a twin foot

switch (optional) control.

Note: The tilter is “raising” when the platform to which the cylinder is attached is moving to the level position.
Therefore, on standard EM1-200 and EM1-500 units, the cylinder(s) will extend when the “UP” control is pressed.
On standard EHTT and EHTT-L units, the cylinder(s) will retract when the “UP” control is pressed.

For all models:

Pressing the “UP” pushbutton or foot switch will turn on the power unit to raise the platform. The platform will
raise only while the control is pressed. Upon releasing the control, the platform will stop and hold its position.

For the EM1-200:

Pressing the “DOWN” pushbutton or foot switch will energize the lowering valve to allow the platform to descend by
gravity (the motor does not run). Again, releasing the control will stop the platform movement, and the unit will hold
its position.

For the EM1-500, EHTT, and EHTT-L:

Pressing the “DOWN” pushbutton or foot switch will turn on the power unit to lower the platform. Releasing the
control will stop the platform movement, and the unit will hold its position.

Caution: Never use the tilting table if any damage or unusual noise is observed, if it is in need of repairs, or if it seems
to be malfunctioning. Notify your supervisor or maintenance personnel if you notice anything out of the ordinary.

Ensure that all safety and warning labels stay in place and are legible. Refer to the labels page in this manual.

ROUTINE MAINTENANCE & SAFETY CHECKS – EM1-200 & -500, EHTT, EHTT-L

o Warning: Care should be taken to identify all potential hazards and comply with applicable safety procedures

before beginning work.

o Warning: The load must be removed, and the platform either positively and adequately supported or fully tilted,

before any work is performed on the tilter.

o Only qualified individuals trained to understand mechanical devices and their associated electrical and hydraulic

circuits should attempt troubleshooting and repair of this equipment

(A) Before each use inspect for the following:

1.) Frayed wires

2.) Oil leaks

3.) Pinched or chafed hoses

4.) Damage or structural deformation to the structural members, the cylinder brackets, etc.

5.) Unusual noise or binding, or evidence thereof.

6.) Proper functioning of all limit switches.

(B) Inspect monthly for:

1.) The oil level. Oil should be within 1” of the reservoir’s fill hole with the cylinder retracted.
See below for the hydraulic oil specification.

2.) Worn or damaged hydraulic hoses and electrical wires.

3.) Hydraulic fluid leaks in any part of the hydraulic circuit.

4.) Pivot point wear.

5.) Rollers’ looseness and wear. (EHTT-L only.)

6.) Integrity of the retaining hardware on all rollers and on all pivot point pins.

7.) The integrity of the frame anchor bolts, and for cracks in the concrete around them.
(Non-portable units only.)

8.) Damage or evidence of fatiguing to the fork tubes. (Portable units only.)

9.) Evidence of fatigue (deformation of the structural parts, cracked welds, wrinkled paint). Check the entire
machine, especially diligently at points that can receive shock-loading such as at hinge pivot areas and cylinder
brackets.

10.) Unusual noises or movement during operation.

11.) All the information, safety, and warning labels being in place and in good conditi on.

12.) The need to clean off dirt and debris.

♦ Grease the cylinder pins monthly with bearing grease.

(C) Yearly inspection
The oil should be changed if the oil darkens, becomes gritty, or turns a milky color (indicating the presence of water).

Replace with an anti-wear hydraulic oil with a viscosity grade of 150 SUS at 100°F, (ISO 32 at 40°C). Ex: AW 32 or HO
150 hydraulic oil, or a non-synthetic transmission fluid. You may use a synthetic transmission fluid if you flush the
system with the synthetic fluid before filling the reservoir.
