12. With the leveler square in the pit and flush with
the surrounding dock floor, remove the banding on
the lip of the leveler.
13. Using an external lifting device (i.e. crane or fork
truck) attached to the platform lifting brackets, slowly
raise the platform. Check for binding as platform is
being raised.
14. If binding occurs, lower the platform. Reposition
leveler and/or add or remove shims as necessary.
Slowly raise platform again. If platform still binds,
contact Systems, LLC Technical Services for further
instructions.
15. Once leveler is flush, square and does not bind:
a. Install shims under maintenance prop (
D
)
where prop attaches to leveler frame. Make sure
prop is solidly shimmed.
b. Raise maintenance prop (
D
) to the service
(upright) position and lock prop in this position
using an OSHA approved locking device.
16. Remove air bellows from the leveler by unbolting
the bellows from the frame and the deck, or wrap
the bellows and air valve with a fireproof blanket to
protect from weld sparks and splatter.
17. 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.
Note:
Figure 11 shows a typical weld pattern. The
weld pattern will vary slightly depending on size of
dock leveler.
18. Weld front of dock leveler frame (
B
) to shims
located under the keepers, then weld the shims to
the front pit curb steel.
Install Dock Leveler (continued)
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 to malfunction and shorten the
lifespan of the affected components.
DO NOT use the maintenance prop to support the
raised platform until the maintenance prop has
been properly shimmed and welded. The shims
must be welded to each other, and also to the
leveler frame.
