TRUS<T>LIFT™ 750 MANUAL REVISION D, OCT 29, 2014 Section 1: Intro
Thank you for selecting the Trus <T> Lift. When operated properly the Trus<T>Lift is designed
to provide years of trouble free service. This manual is provided to show you how to operate
the lift safely and efficiently. Please read this manual thoroughly before installing and
operating your lift for the first time. We recommend your lift be installed and serviced by a
qualified service technician. Section 2: Safety
Read all instructions thoroughly before installation or use of this lift. Failure to do so could
result in serious injury or death.
Refer to local building codes, elevator codes and elevator authorities to ensure installation
is safe and meets your local regulations.
The tower component of all lifts over 52” travel must be secured to the building for
additional support. For commercial installations we recommend the tower be secured to
the building for all lifting heights.
We recommend your lift be installed and serviced by a qualified service technician.
Do not override any of the safety devices provided with the lift
Make sure that there is nothing obstructing the carriage travel before operating the lift.
Make sure there is a minimum of 2in (50mm) and a maximum of 3in (75mm) clearance
between any part or edge of the carriage that could possibly be used as a supporting
handhold and any part of the fixed installation to prevent the trapping of a hand during the
travel of the carriage.
The lift is intended for use by one passenger and one wheelchair only, to a maximum of 750
lb. (DO NOT OVERLOAD THE LIFT).
Make sure that the passenger and the wheelchair are completely on the carriage before
raising or lowering the lift.
Please use the handrails while the carriage is in motion.
This list may not be exhaustive, due care around mechanical equipment should be
observed. If uncertain, please contact the manufacture or a qualified installer.

TRUS<T>LIFT™ 750 MANUAL REVISION D, OCT 29, 2014 Section 3: Operating Instructions
Plug the unit into your power supply. On the end of the power cord you will n d the gold
key to open the control box, use this to open the main control box by pushing in hard on the
box with one hand to compress the weather seal while turning the key with the other hand.
All other keys for the unit will be hanging on the back of the control box door.
To raise or lower the carriage press either the UP or DOWN paddle (See Figure 1) and
maintain continuous pressure on the paddle until the lift stops automatically at the landing.
If you decide to change the direction of travel of the lift before it reaches the landing, you
must release the paddle and wait for the lift to come to a COMPLETE STOP before pressing
the other paddle.
Your lift features the patented zero load start system that ensures the best performance in
extreme hot or cold by reducing the stress on the drive system. When you reach the bottom
landing the motor will continue to run for a couple of seconds and when you start up from
the bottom landing the motor will run for a couple of second before the platform starts to
move.
If you need to stop the lift before it reaches the landing, simply release the UP or DOWN
paddle and the carriage will stop immediately. You can also stop the lift by pressing the red
STOP button (See Figure 1). To release, simply pull out the button.
A key switch is located near the UP and DOWN paddles to prevent unauthorized use of the
Trus<T>Lift. The key is removable in both positions. The switch may be turned off and the
key removed making the paddles on the carriage inoperable. When you wish to use the lift
again insert the key, turn the switch on, and remove the key. It is recommended that you
have the key readily available whenever operating the lift.

MANUAL CRANK OPERATION
If a power outage occurs while the lift is in use and a passenger is stranded between landings,
the carriage can be manually raised or lowered using the Hand Crank Tool provided. First verify
manual cranking is required, ensure the stop button is pulled out, the control key is turned on
and the lift is plugged in. If manual cranking is still required follow these steps:
When manual cranking the lift there is a
pinching risk between the belt and the
pulleys. Keep your hands, hair, clothing and
jewellery clear of the drive belt.
Unplug the power cord
Remove the top cover of the lift
Use the 15/16” socket and ratchet
provided to crank the bolt on the top
center of the tower (See Figure 2).
Turn the Hand Crank Tool clockwise
to raise the lift and counter-clockwise to lower the
lift.

TRUS<T>LIFT™ 750 MANUAL REVISION D, OCT 29, 2014 Section 4: Installation – Site Preparation 4.1 Mounting location
The Trus<T>Lift requires a solid, smooth,
and level mounting surface. When
mounting on a concrete pad ensure there is
a minimum of 6in from any anchor point to
the pad edge to prevent cracking the
concrete. Plan for a minimum of 60in x
60in additional space (not including the toe
plate) on the lower entrance side to allow
enough space for the wheelchair to
manoeuvre onto the lift. The specific size of
the lower landing may vary depending on
the specific lift in question and you should
consult your RAM dealer or RAM directly to
ensure you prepare the site correctly.
The mounting surface must be solid enough to support the lift and its maximum rated
load. If you need a load diagram please contact your RAM dealer or call 1-800-563-4382.
Note: The Trus<T>Lift ships with four 3/8” x 2 ¾”
concrete wedge anchors.
For wedge anchor installation information visit
http://trustram.com/concrete-anchor/ 4.2 Travel Wall
The travel wall is the wall below the upper entrance/exit point of the lift (Figure 4). This
wall should be vertical, smooth, and free of gaps or protrusions for the entire travel
distance of the lift. 4.3 Power
A 110 VAC 15A electrical receptacle must be provided within 6 feet of the tower side of
the lift. You can use an extension cord if required. Total length of line including the cord
attached to the unit must not exceed 20 ft. Use only 14 gage extension cord. Residential
lifts should use a dedicated circuit where possible. Commercial applications require a
disconnect and a dedicated circuit.

TRUS<T>LIFT™ 750 MANUAL REVISION D, OCT 29, 2014
RAM manufactures numerous lift con gurations. For lifts that have additional
options (including commercial lifts) please see Section 6. The basic lift assembly
instructions apply to all lifts regardless of con guration.
Section 5: Installation –Basic Lift Assembly
Position the tower on the mounting deck
close to the final install position. (Note:
choose a location where the carriage
components can be assembled easily with
the intention of moving the unit into final
position after tower, base legs and carriage
are fully assembled). (Figure 4)
Slide the base legs under the base angles on
the tower.
Use safe lifting practices along
with a dolly or other appropriate lifting equipment
to move the tower into place.
Securely fasten base legs to the tower as
shown in Figure 5 using provided ½ NF x 1
¼” cap screws, ½ lock washers and ½ flat
washers.
Adjust the front and back base leg load-
support screws to lift the base frame
slightly off the ground.
Note: Do not attach the base frame to the
ground at this point, this setting will ensure
the lift is supported on the outer points of
the base frame for maximum stability. Later in the
process the mid-load support screws will be
adjusted to just touch the floor with no load on
the carriage before the base legs are anchored to the ground.

The upper stopping point (upper
limit) bracket is located on the front
cover support tube behind the front
cover of the main tower (Figure 12).
Remove the top cover and front
cover, and use a Robertson
screwdriver to loosen the upper limit
bracket. Slide the bracket down until
the upper limit switch clicks. Tighten
2 screws on the limit to hold it in
place. Move the lift down and back
up to test that the limit is set at the
correct height to stop the platform
at the upper landing. Once the limit
is in the correct place, use the self-
drilling and tapping screw provided
to set the limit in place.
When replacing the front cover ensure that the gap between the side covers and
the front cover is even. If it is not even damage could be done to the electrical/
control cables that run between the panels as they move up and down with the
carriage.

TRUS<T>LIFT™ 750 MANUAL REVISION D, OCT 29, 2014
The lower stopping point (lower limit) for a RAM Trus-T-Li ™ is not typically set
in the field. With RAM’s Zero-Load Start system the li turns off automa cally
when the carriage platform reaches the ground. The li will come to a stop as
the lower limit sensor is actuated. This occurs as the drive nuts c e to move
through the slots in the guide frame for a short me a er the pla orm comes to
a rest on the lower land
In cases where the RAM Trus-T-Li ™ is being used to replace a product that had
a pit that was deeper than that required for our product you may need to stop
the li before the li pla orm comes in to contact with the bo om of the pit. In
these cases you can use some form of rigid blocking that will withstand the full
load of the landed carriage pla orm. If you are uncertain whether this is the case
please consult your RAM Dealer or contact RAM technical support. Section 6: Installing Options
The installa on of a li with op ons differs from a basic unit in that it requires all
peripheral safety devices (i.e. upper interlock, lower interlock and safety Pan) to be
wired up at least temporarily in order to run the motor.
Lower limit switch (item
45) not ac vated yet but as
drive nuts (items 46) travel
further the switch will get
pressed and stop li
movement
As pla orm or mechanical
stops (for li s equipped
with a safety pan) comes in
to contact with the ground
the bolts will travel down in
the slot bringing the safety
bracket (item 44) down as
well.

Section 8: Tall Tower Lifting Instructions
Working with Tall Towers can be difficult and dangerous if done incorrectly. This is the
recommended method and should be followed at all times. Failure to do so can result in serious
injury or death. Under no circumstance should you attempt to lift or maneuverer a Tall Tower
unit by muscle power alone.
8.1 Lifting Tools Required.
Using the right tools will decrease your chances of having an accident. However no tool can
replace forethought or common sense. Always plan your project well in advance.
Spreader Bar – Ensure that the Spreader Bar you are using is rated for the weight of the
lift you are attempting to lift. Confirm the unit weight with RAM before lifting.
2 – 500 lb. Capacity Lifting Straps – Only straps that are in good condition should be
used. Do not use frayed or worn straps as their capacity may be compromised.
Lifting Device. Remember that whatever device you intend to lift the unit is weight rated
properly. Check with the supplier of this device if unsure.

TRUS<T>LIFT™ 750 MANUAL REVISION D, OCT 29, 2014 Section 9: Maintenance
9.1 Monthly Inspection: 9.1.1 Inspect all gates/doors and ensure they are locked when the lift is not at the landing. Also check that the lift will not run unless the gates / doors are fully closed and locked once the platform is more than 2” (50mm) from the landing. 9.1.2 Inspect the toe plate and ensure it is operating smoothly and moving into the up position when the lift leaves the lower landing
9.2 Annual Maintenance:
The Trus <T> Lift should be inspected and maintained annually. The following is a
non-exhaustive list items that should be checked as part of an annual
maintenance in order to maintain safe operation of your lift. An inspection and
maintenance is required to be completed by an authorized RAM dealer for any
extended warranty claims to be valid. 9.2.1 Inspect the drive nuts
Compare the amount of movement in the drive nuts from side to side
and up and down without rotating the drive nut at all. If they feel overly
sloppy or as though threads may be missing then they need to be
replaced. Signs of bronze thread material or shavings are another
indicator of worn lifting nuts. If the amount of movement is minimal spin
the drive nuts by hand to check for resistance, if any resistance is felt or
the drive nut binds then they must be replaced. Refer to Replacing the
Drive Nuts Section 9.3 9.2.2 Inspect the drive screw
Inspect the drive screw for any irregularities, sharp edges or foreign
objects and dirt caught in the threads. Be sure no damage exists to the
drive screw and that it is entirely clean of debris. Replace screw if
damaged. 9.2.3 Clean and re-lubricate the drive screw
In order to lubricate the drive screw you must remove the main front
panel and a carriage guide frame panel (Fig M1 and M2). Use a clean rag
to wipe all of the grease off of the screw. Liberally apply Mobil SHC-460
grease on the drive screw by hand.

TRUS<T>LIFT™ 750 MANUAL REVISION D, OCT 29, 2014 9.2.4 Inspect the drive belt
Remove the top cover and inspect the drive belt for wear. A small
amount of black rubber bits below the belt is normal. If there is any
significant sign of wear to the belt, replace. 9.2.5 Inspect for surface damage and complete touch ups to coatings
Wear and tear may occur on powder coated steel surfaces resulting in
scratches. Small points of damage can be wire brushed and touched up
with the small touch up paint containers that come with each lift RAM
ships out. This will extend the life and cosmetic look of you lift and is
particularly important in any environments that are coastal or potentially
corrosive. 9.2.6 Inspect cables
Tears in insulation should be patched where possible and if bare wire is
present new replacement cables should be purchased and installed by a
qualified technician. Consult your RAM dealer for spare parts should they
be required. 9.2.7 Inspect for correct functioning of toe plate – if applicable
The tow plate actuation mechanism may be critical to access and the
both the mechanism and the toe plate itself should be examined. If there
are any concerns adjust the mechanism or repair/ replace it. 9.2.8 Re-check platform alignment and clearances
Buildings and construction “settles” over time and adjustments may be
required to ensure good clearances and alignment of the lift. Consult the
appropriate sections of the installation manual or RAM’s technical
support team for guidance. 9.2.9 Inspect and Test All Interlocks and Safety Devices
Interlocks and all other safety devices should be tested to ensure they
work in the appropriate manner. If you are uncertain whether they are
operating correctly please consult with your RAM dealer or call RAM’s
technical support team.
