14. Weld front of dock leveler frame (B) to shims
located under the keepers, then weld the shims
to the front pit curb steel.
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.
15. With the leveler welded in place remove the
shipping bands from around the lip and frame.
16. Disconnect lifting device and chains from the
lifting brackets.
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 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 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.
