Determining the Correct Lift Configuration
Indoor or Outdoor?
RAM Trus-T-Lifts are designed to withstand harsh climates. The Trus-T-lift is designed to be used indoors or outdoors. You should however, properly determine where the lift would be situated. This will help you configure the lift correctly for the application and ensure RAM can give you the best advice possible.
Is how high the rider will be lifted, this is determined by measuring the total lift height required. Finished floor – to Finished Floor.
Note: Each lift is rated to a maximum lift height that cannot be exceeded.
Depending on your configuration, the top of the Trus-T-Lift platform, can be anywhere from 1 ¾” to 2 ¾” from the surface it sits on. Those dimensions are included in the total travel. As an example: If the lift is rated for 12’ travel, you have already travelled 1 ¾” or 2 ¾” by getting on to the platform. The remaining maximum distance of travel is therefore less than 12’.
The distance the lift travels and then stops, is determined by setting the upper limit switch. Once the travel distance is determined and the upper limit switch is set, the lift will not travel further than that point. This point can be set on site and can also be adjusted as often as required.
Always ensure the platform is level with the landing as it arrives at the destination. The rider should be able roll off smoothly from the platform to the landing. Setting the platform height higher or lower than the landing is not recommended but when setting the platform at the top landing if there is no passenger you can adjust to slightly higher than the landing point so that when a passenger does use and it flexes slightly they will roll off at an even level.
If the lift is set into a depression or pit, (as is the case with some installations) then your overall travel measurements should include the depth of the depression.
The Tower placement and therefore where the onboard controls are located need to be determined before ordering a lift. Approaching the lift from the bottom level – Is the tower on your left or right hand?
There are 2 basic platform styles that can configured as required.
Straight Through Platform
Determine which side your tower is located. Always work from the bottom level up when configuring your lift. Use the face of a clock as a reference point. Example: The bottom level, entering the lift – would be 6 o’ clock. The top level would be 12 o’ clock as you exit.
You can also configure the platform as Same Side Entry/Exit. This is accomplished by adding a Solid End Wall at the 12 o’ clock position on the platform – forcing the rider to exit on the same side they entered. Enter at 6 o’clock. Exit at 6 o’clock.
Adjacent (90 degree) Platform
Determine which side your tower is located. For this example the tower will be on our Right Side as we approach the lift from the bottom level. 6 o’clock. An adjacent platform would then require you to exit the lift at 9 o’clock. Conversely if the tower was on your left (6 o’clock) the rider would exit at 3 o’clock.
