INSTALLATION
14. Remove shipping bands at this time. Allow platform
to float. Add/Remove shims as necessary to bring
platform level/flush with floor.
15. Weld front of dock leveler frame (B) to shims
located under the keepers, then weld the shims to
the front pit curb steel.
16. Disconnect lifting device and chains from the lifting
brackets.
17. Pull and hold the release ring (located in recess
at rear of platform) until the platform is fully
raised. Check for binding as platform rises.
18. Slowly walk out onto the platform to lower the
platform. Allow the platform to lower to the
cross-traffic position. Check for binding as platform
lowers.
19. If binding occurs, reposition leveler and/
or add or remove shims as necessary. Raise
and lower platform again. If platform still binds,
contact Poweramp Technical Services for further
instructions.
20. Check that the leveler is flush with the dock floor
and that the platform lip contacts both lip keepers
evenly.
NOTE: The illustration on the previous page shows
a typical weld pattern. The weld pattern will vary
slightly depending on size of dock leveler.
13. With the rear hinge frame angle (F) tight against
the rear pit curb angle (G), weld the rear hinge
frame angle (F) to the rear pit curb angle (G) using
a 3/8 in. (9.5 mm) flare bevel skip weld-each weld
being 6 in. (152 mm) long.
Start at each end with a 6 in. (152 mm) long
weld. Space all the other welds out evenly leaving
approximately 6 in. (152 mm) space between each
weld.
Alternate welding locations to distribute heat.
Welding sequentially from one end to the other
may cause warping or distortion.
Make sure all personnel are outside of the leveler
operating zone and stand clear of the platform lip
before removing the shipping bands. Failure to do
this may result in serious personal injury or death.
IMPORTANT
When activating the leveler, always pull AND hold
the platform release ring until the platform is at the
full-raised position. Releasing the ring while the
platform is still rising may result in damage to the
equipment.
IMPORTANT
Always ground welding equipment to the dock
leveler frame, NEVER to the platform.
DO NOT weld continuously along the full length of
the rear hinge frame angle. This can put unnecessary
stress on the leveler components, causing the
leveler not to function correctly and shortening the
lifespan of the affected components.
DO NOT grind or weld if hydraulic fluid or other
flammable liquid is present on the surface to be
ground or welded.
DO NOT grind or weld if uncontained hydraulic fluid
or other flammable liquid is present. Stray sparks
can ignite spills or leaks near the work area. Always
clean up the oil leaks and spills before proceeding
with grinding or welding.
Always keep a fire extinguisher of the proper type
nearby when grinding or welding.
Failure to follow these instructions may result in
serious personal injury or death.
Make sure all personnel are outside of the leveler
operating zone and clear of the platform lip before
activating the leveler. Failure to do this may result
in serious personal injury or death.
