CAUTION!
Precaution should be taken to prevent the introduction of contaminates
such as dirt or other foreign material into the system through open fittings,
pipes, or disassembled components. Contamination will ruin the hydraulic
system.
12. Raise the floating end up off the 4” x 4” board. Remove the drums and lower the
floating end as near as practical to a position level with the pit curbs.
13. Align the platform in the pit adhering to the clearances on the drawing. NOTE:
The 1_” dimension (pit to platform) is an absolute minimum due to the cantilever
action of the platform over the hinge clevises.
14. After the alignment is complete, shim the four hinge clevis pads so that all four
clevises are sitting solid on the embedded hinge channel. Because of applied
loads, the hinge clevis pads must receive a minimum of 5/16” fillet weld for the
entire perimeter.
15. Pit floors usually vary to some degree from one side to the other. If the cylinder
clevis channel were butted against the pit wall and lagged down, the pistons might
not stroke out together which would cause a twist in the structure. This is why it is
recommended that the unit be raised until the rams stroke out. Shim the free side
either behind to the wall or underneath to the floor to achieve equal and
simultaneous stroke out. Then lag it to the floor.
16. Operate the unit and carefully inspect for hydraulic leaks and physical stresses.
17. Raise the lift all the way up to locate the bridge channel and weld into place
following the welding instructions on the installation drawing (see Figure 11).
18. The hinged service cover lid is held down with the cover locks. Position these
locks and install them into the center section.
19. Finish welding the center section per the installation drawings and weld the skirts
to the sides of the platform (see Figure 11).
