IMPORTANT
!
Do not install, operate and/or service this leveler until you
have read and understood all of the safety information
and instructions contained herein and on the leveler.
Do not work under or around leveler being installed
without first placing adequate barriers to positively
prevent vehicle traffic from entering the work area.
Keep hands and feet clear of dock leveler pinch points.
WARNING
!
!
The information below is crucial to proper installation:
Pit Curb Angles
A. Must be level side-to-side and front-to-back.
B. Must be square at both rear corners.
C. Side curb angles must be parallel to each other.
D. Finished floor to be flush with top surface of curb angle.
The leveler must be welded to a firmly embedded steel or other
dock steel as described in the installation instructions.
Do not attempt to use only bolts or anchors, to attach the dock
leveler to the concrete.
1. Prior to installation, clean pit thoroughly and verify that all
dimensions are in accordance with manufacturer
specifications.
2. Measure height of rear corners of dock leveler, bottom of
frame to top of deck plate, typically 19” or 23”(485 or
585mm). Measure depth of pit at both rear corners where
rear bottom corners of frame will be positioned. Locate and
place suitable shims (not supplied) in pit corners to produce a
depth to match frame height.
3. Measure height of dock leveler front corners, bottom of frame
to top of deck plate, typically 19-1/2” or 23-1/2” (495 or
595mm). Measure depth of pit at both front corners where
front bottom corners of frame will be positioned. Locate and
place suitable shims (not supplied) at both front corners to
produce a depth to match frame height. See Figure 1.
!WARNING
!WARNING
All electrical work must be performed by trained and authorized
personnel.
4. Prepare to hook up electrical wires and hydraulic hoses if
required. Identify hose ends as “Lip” and “Deck”. For units
with self-contained (mounted under deck) power pack,
establish a temporary electrical hook-up to enable deck to be
raised and lowered during installation. For units with a wall
mounted (remote) power pack, prepare hydraulic hoses for
“pulling” through conduit and electrical wires for temporary
hook up.
Use caution when lifting or moving the leveler. Do not attempt
to lift without suitable hoisting equipment capable of lifting as
much as 3500 lbs. Do not work beneath a raised object. Follow
all hoisting safety requirements.
5. Using extreme caution, sling dock leveler into place squarely
above pit and lower gently onto pre-located shims. Locate
and square dock leveler to best suit pit and dock face. Space
between sides of deck and sides of pit should be equal. Line
up the bottom clevis holes to the pivot edges of the rear
frame.
It is important that the shims fill the space between the
bottom edge of the back beam and face of the curb angle, as
well as behind each hinge lug on the top edge. Confirm that
the top of the back beam is flush with the top surface of the
rear curb angle, and then finish weld back beam to curb
angle.
6. If the rear beam does not line up squarely with the rear curb
angle, use 3” x 6” (75mm x 150mm) shims of suitable
thickness to fully support top rear and bottom rear of rear
beam at weld areas. Weld rear beam to curb steel with 1/4”
x 6” (6mm x 150mm) welds, on 9-5/8” (250mm) centers.
7. Remove sling brackets, chains, etc. from the deck. Remove
and discard the shipping bolt from the front of the dock
leveler lip plate. Remove the bolts from the upper shipping
hole in the rear tilt bars and place them in the lower operating
holes.
8. Check the deck height to confirm that it is flush with the top
of the side curb angles and tack-weld all front shims to the
front curb angle and front frame.
9. Adjust the lip proximity sensor by loosening the holding nuts
and setting the gap. Once the desired adjustment has been
achieved, re-tighten the holding nuts.
