Section 1: Intro
Thank you for selecng the Trus <T> Li. When operated properly the Trus<T>Liis designed
to provide years of trouble free service. This manual is provided to show you how to operate
the lisafely and efficiently. Please read this manual thoroughly before installing and
operang your lifor the first me. We recommend your libe installed and serviced by a
qualified service technician.
Section 2: Safety
Read all instrucons thoroughly before installaon or use of this li. Failure to do so could
result in serious injury or death.
Refer to local building codes, elevator codes and elevator authories to ensure installaon
is safe and meets your local regulaons.
The tower component of all lis over 52” travel must be secured to the building for
addional support. For commercial installaons we recommend the tower be secured to
the building for all liing heights.
We recommend your libe installed and serviced by a qualified service technician.
Do not override any of the safety devices provided with the li
Make sure that there is nothing obstrucng the carriage travel before operang the li.
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 supporng
handhold and any part of the fixed installaon to prevent the trapping of a hand during the
travel of the carriage.
The li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 li.
Please use the handrails while the carriage is in moon.
This list may not be exhausve, due care around mechanical equipment should be
observed. If uncertain, please contact the manufacture or a qualified installer.

Section 3: Operating Instructions
Plug the unit into your power supply. On the end of the power cord you will nd 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 connuous pressure on the paddle unl the listops automacally at the landing.
If you decide to change the direcon of travel of the libefore it reaches the landing, you
must release the paddle and wait for the lito come to a COMPLETE STOP before pressing
the other paddle.
Your li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 boom
landing the motor will connue to run for a couple of seconds and when you start up from
the boom landing the motor will run for a couple of second before the plaorm starts to
move.
If you need to stop the libefore it reaches the landing, simply release the UP or DOWN
paddle and the carriage will stop immediately. You can also stop the liby pressing the red
STOP buon (See Figure 1). To release, simply pull out the buon.
A key switch is located near the UP and DOWN paddles to prevent unauthorized use of the
Trus<T>Li. The key is removable in both posions. The switch may be turned off and the
key removed making the paddles on the carriage inoperable. When you wish to use the li
again insert the key, turn the switch on, and remove the key. It is recommended that you
have the key readily available whenever operang the li.

MANUAL CRANK OPERATION
If a power outage occurs while the li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 buon is pulled out, the control key is turned on
and the liis plugged in. If manual cranking is sll required follow these steps:
When manual cranking the li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 li
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 liand counter-clockwise to lower the
li.

Section 4: Installation – Site Preparation
4.1 Mounting location
The Trus<T>Lirequires a solid, smooth,
and level mounng surface. When
mounng 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 addional space (not including the toe
plate) on the lower entrance side to allow
enough space for the wheelchair to
manoeuvre onto the li. The specific size of
the lower landing may vary depending on
the specific liin queson and you should
consult your RAM dealer or RAM directly to
ensure you prepare the site correctly.
The mounng surface must be solid enough to support the li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>Liships with four 3/8” x 2 ¾”
concrete wedge anchors.
For wedge anchor installaon informaon visit
hp://trustram.com/concrete-anchor/
4.2 Travel Wall
The travel wall is the wall below the upper entrance/exit point of the li(Figure 4). This
wall should be vercal, smooth, and free of gaps or protrusions for the enre travel
distance of the li.
4.3 Power
A 110 VAC 15A electrical receptacle must be provided within 6 feet of the tower side of
the li. You can use an extension cord if required. Total length of line including the cord
aached to the unit must not exceed 20 . Use only 14 gage extension cord. Residenal
lis should use a dedicated circuit where possible. Commercial applicaons require a
disconnect and a dedicated circuit.

RAM manufactures numerous lift congurations.For lifts that have additional
options (including commerciallifts) please see Section 6. The basic lift assembly
instructions apply to all lifts regardless of conguration.
Section 5: Installation –Basic Lift Assembly
Posion the tower on the mounng deck
close to the final install posion. (Note:
choose a locaon where the carriage
components can be assembled easily with
the intenon of moving the unit into final
posion aer tower, base legs and carriage
are fully assembled). (Figure 4)
Slide the base legs under the base angles on
the tower.
Use safe liing pracces along
with a dolly or other appropriate liing 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 lithe base frame
slightly offthe ground.
Note: Do not aach the base frame to the
ground at this point, this seng will ensure
the li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.

5.1 Attach the platform to the tower
Raise the guide frame using the manual
crank or by temporarily plugging the unit in
to a power outlet. Slide the plaorm into
place on the base frame (Figure 6), be
careful not to scratch the base frame.
Hint!! Use packaging foam from the shipping
crate to protect the base legs when installing
plaorm.
Lower the guide frame to line up bolt holes
on the carriage and install the bolts (Figure 7).
Note: ghten the bolts unl the end of the
bolt is 1/8” of an inch out of the lock nut, do
not over ghten the bolts.
Hint!! You can get a beer view of the bolt
extending through the nut by removing the
plasc panels beside on the control box on
carriage wall.

screws with 2 washers and a nut on each
cap screw as shown in (Figure 8).
5.3 Install Toe plate assembly
Raise the carriage to a comfortable
working height, install the toe plate and
ghten all the bolts (Figure 9)
Install the toe plate rocker arm as per (Figure 10)
The toe plate is designed to resist a stac
force of 125 Lbs. to prevent a manual wheel chair from
rolling off of the plaorm. It is recommended that a
carriage gate is used to provide addional protecon when
liis being used by powered wheelchairs, powered
scooters, standing persons or if the user has limited control
of their wheelchair when entering the liat the upper
landing.

5.4 Level the deck and adjust clearance to
travel wall
Using the two plaorm levelling screws provided
(Figure 11) Adjust the plaorm lt so that the
plaorm is level with both top and lower landing
when a load is applied to the carriage. In most
cases seng the levelling bolts to have the
plaorm be even at 50% of expected working load
it preferred.
Posion the tower and adjust the front and back base leg levelling screws (shown in
figure 11a) so that the carriage runs evenly along the travel wall with agap between the
platform edge and travel wall of less than 5/8” (15 mm) for installations in Canada and
¾” for installations in the USA. An example of good running clearance and poor running
clearance is shown in figure 11b.

5.6 Setting the Upper and Lower stopping Positions (Upper and Lower Limits)
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 unl
the upper limit switch clicks. Tighten
2 screws on the limit to hold it in
place. Move the lidown and back
up to test that the limit is set at the
correct height to stop the plaorm
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 dama ge could be done to the electrical/
control cables that run between the panels as they move up and down with the
carriage.

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 plaorm 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.

6.1 Identify the Optional Components for your Lift
Not all lis are shipped with the same components. Be sure to idenfy all the opons you have
purchased before assembly. Follow each step carefully to ensure proper funconality. Parts List
- The opons for the Trus<T>Liare pre-assembled and tested in the factory before shipping.
The liis then disassembled into its separate components. All fasteners required to assemble
the liare re-installed in their respecve posions aer disassembly, except for the Lower
Mechanical Stops (5/8” X 3” Carriage Bolts) included with the small parts bag.
6.2 Locating the Upper Junction Box
Call staons, upper gates and interlocks
terminate in the upper juncon box
under the cover at the top of the li.
Remove the cover from the top of the
li. (Note the lift will not run with the
top cover removed.) Inside there is a
juncon box on the right side, remove
the cover of this juncon box. Inside
the juncon box there is a cable with
individual wires labeled with numbered
tags. Number tags are also on the end
of the wires coming from the opon to be hooked up. Figure 13
Mount the call staon, upper gate and or
interlocks into their respecve posions.
Run the wires from each opon to the
upper juncon box through conduit. Using the wire nuts provided match the number
on the wires to complete the terminaons.

There are two scenarios for installing
interlocks. The first is that the interlock is
pre-mounted on a carriage gate or landing
gate you have purchased from RAM.
The second is that you have purchased
interlocks to mount on doors or gates you
will be providing.
Unplug the unit. Disconnect your
temporary connecons of the upper
gate/interlock to the outside juncon box-
Do not cut the wire numbers o, you will
need them again!
Once you have installed conduit (not
supplied) and run your wire leads back to
the Top Juncon Box on the li. Remove
the cover from the top of the li. ( Note
the lift will not run with the top cover
removed.)
Inside there is a juncon box on the right
side, remove the cover of this juncon box.
Inside the juncon box there is a cable with
individual wires labeled with numbered
tags.
Number tags are also on the end of the
wires coming from the opon to be hooked
up. Use the wire nuts provided to match
the number on the wires to complete the
terminaons.
