Items Needed:
Qty
Description
2 Drive Base Channels (6” channel)
Varies Intermediate Channels (6” channel)
2 Installation Angles (with holes drilled in each end)
varies 1/2" x 2” grade 8 Hex Head Cap Screws, Washers & Nuts
1. The masts are designated “left front” , “right front”, “left back”, and “right back” with
a welded “LF” , “RF”, “LB” and “RB” marked on the mast beam base plate. The left
hand side is to your left and the right hand side to your right as you stand at the
lower level and look at the lift (the guide angles are always on the inside of the
beams). Arrange and orientate the mast beam assemblies while they are laying
down with the outside of the beams facing up (guide angles facing down).
2. Using the intermediate channels and drive base channels (refer to Figure 10) and
the high grade 1/2" x 2” lg. bolts, lock washers, and nuts provided, bolt the “RF” and
“RB” masts together per Figure 21. Then bolt the “LF” and “LB” masts together.
Remember to torque all bolts to 99 ft-lbs.
3. Raise each beam pair assembly and place along side the carriage in the correct
orientation (guide angles on the inside of the beams). Refer to Figure 22.
4. Slide the beams into position along side the carriage. The wheel guide assemblies
should align with their respective mounting holes on the carriage upright bars. Bolt
the wheel guide assemblies to the bars using the 1/2" x 2” long, Grade 8 bolts and
the 1/2" washers that have been provided. Torque all these bolts to 99 ft. lbs. as
shown in Figure 23.
5. Two installation angles have been shipped with your unit to properly space the two
front beams and the two back beams apart temporarily prior to securing beams to
the floor.
NOTE: Make absolutely sure the beam pairs are secure with chain or
temporary bracing.
WARNING !
Do not depend on the carriage uprights and wheel blocks to support the
beams! Use other means to support and secure the beams in the raised
position during installation and prior to final bracing. Improperly or
inadequately supported beams could fall and cause serious injury to
adjacent personnel or permanent damage to the equipment.
