. Measurements to locate the ramp platform bracket
position are calculated from the rear face of the
ramp plate to the center of the hole in the ramp
platform bracket, See Figure 10
.
2. A visible reference line should be drawn at the
above determined position, extending between both
deck support beams.
3. From the reference line towards the rear of the
leveler, measure and draw a line at 8⅜".
4. From the reference line in step 2 towards the front
of the leveler, measure and draw a line at 4¾". You
will now have located a combined area of approx.
13 ⅛". This marks the spot where the 2 angles
and ramp platform bracket will be positioned. See
Figure 10.
For Serco Brand Levelers, use Steps
5A or 5B, then proceed to Step 6
.
For
other brands of dock levelers, proceed
directly to step 6.
5A:
Serco dock levelers make use of a center deck
support channel. As a result, 20" pit levelers will
require additional main lifting cylinder clearance.
To provide the additional clearance needed, remove
the portion of the center support channel marked
off for the ramp platform bracket described in step
4. This 13⅛" area of the deck plate should be
ground flat enough to allow you to "flush mount" the
platform bracket assembly. See Figure 12.
5B:
serco 24" pit levelers:
Measure the height
of the center support channel and subtract ¼". In
the same 13⅛" area described in step 4, locate the
next (left and right of center) support channels and
mark this measurement to the inboard sides. This
is where the 2 support angles will be welded. See
Figure 12.
When properly installed, the platform clevis base
plate should span from the 2 outside angles
across and to the flat surface of the center support
channel. See Figure 12.
6. To evenly distribute the platform load when raising
the leveler, weld the 2 pieces of angle iron into the
marked off area along the support beams and deck.
The weld must be continuous and surround the
entire perimeter of the angles. See Figures 11 and
12.
7. After the angles have been completely welded in
position, center and align the flat base plate to the
angles with the holes closest to the front of the
ramp. Weld the plate into position on the angles.
See Figures 11 and 12.
Always disconnect main power before doing any
welding. Always attach ground lug to the part
being welded.
