INSTALLATION
9. Use fork truck (or other method) to raise dock leveler platform to a height that will allow use of the maintenance
prop. The maintenance prop is accessible when the platform is raised. The top of the prop should be positioned
directly behind the front header plate of the platform. See Figure 4
10. Make sure that the front and rear legs are resting firmly and securely on the shims set on the pit floor. Do not
weld shims at this time.
11. Use a fork lift (or other method) to raise the leveler platform. Remove the maintenance prop. Set the platform
in the cross traffic position (lip fully folded, inside the keepers, and the platform level with the dock floor). See
Figure 5.
12. Make sure the dock leveler deck is flush with the dock floor and that the top rear frame angle of the unit is
tight against and flush with the rear pit curb angle. Raise platform install correct size shims. Check for equal
clearance between the sides of the platform and the pit walls.
13. Weld the top rear frame angle to the rear pit curb angle. Weld behind each hinge tube of the leveler platform.
See Figure 6
14. Powerhook KS6 units only: Tack weld the shims under the front legs to the legs, the plates imbedded in the
pit floor, and to the pit front curb angle. This should be done from outside the pit prior to raising platform. See
Figure 6
15. Repeat step 9.
16. Finish weld all shims to unit and, where possible, to plates or pit curb angles. Weld shims together where
stacked
17. Refer to Figure 8.
A. On levelers with single hoist cylinder, shim the hoist cylinder support so that the center channels are level.
Weld shims in place.
B. On levelers with dual hoist cylinders, shim under the cylinder supports so that the side channels are level.
In addition, shim under the center beam support so that the center beam is level. Weld all shims in place.
18. Weld fish plates to the center channels of the leveler and to the plate imbedded in the rear pit wall. refer for
recommended fish plate sizes and location. Figure 7
19. Clean and paint all welds
20. Weld and/or bolt bumpers in place on face of dock. Refer to certified Pit Drawing.
21. If leveler is part of a Centrapower system or if the power pack is located remotely, connect the hydraulic hoses
to the dock leveler as indicated in the Centrapower manual instructions
22. Check the hydraulic fluid level. Standard units are shipped with the reservoir full. However, fluid level should
be checked before operation unit for the first time to make sure no fluid loss occurred during shipment or
installation. See the Preventative Maintenance Section.
Note: For Centrapower or remote power pack units, see appropriate instructions
23. If the electrical installation is to be preformed at a later date, use a fork lift to set the unit in the cross traffic
position (lip fully folded, inside the lip keepers and the platform level with the floor).
