Poweramp VS VERTICAL SPECIALTY 5.2007 - Manual (Page 8)

Vertical Storing Dockleveler Installation
With the VS dockleveler frame properly installed, the dockleveler can now be positioned.
1. Poweramp VS docklevelers are shipped with lifting lugs attached to the outboard joists.
These lugs must be moved to the 3/4" hole provided in the lip for installation (See Fig.
3).
2. Lift platform into vertical position by lifting lugs and position VS leveler platform with
three (3) rear hinge tubes in line with matching frame hinge weldments.
3. Insert three (3) hinge pins through hinge assemblies and lock with cotter pins provided.
4. Raise free end of collapsed storage prop from frame and pin to platform as shown in fig.
4, lock with cotter pin. Engage locking bolt in storage prop as shown on page 9.
5. Electrically connect field wire. Wire power cables to junction box on rear pit wall.
NOTE: Conduit must be able to flex as the dockleveler moves. Make necessary
electrical connection in control enclosure.
6. Remove 3/8" NPT pipe plug from top of reservoir and replace with breather cap (See
Fig. 7).
7. Hoist cylinder must be hydraulically extended to install. Warning: When a hydrau-
lic cylinder is extended, it must be full of hydraulic fluid to support a load.
Extending hydraulic cylinders by a means other than hydraulic power can
result in severe personal injury or death. Turn on power and press "RAISE"
push button. Note: watch that rod of cylinder clears any obstructions while extending.
When cylinder is fully extended release "RAISE" push button and use "LOWER" push
button to retract rod about 1/2 inch for internal clearance.
8. Use adjustable rod end to position hole line up for insertion of pin and clips. Lock jam
nut. No more than 1/2" of thread may show for a proper installation.
9. Mount storage prop limit switch (located in platform with tie wraps) to base plate with
screws provided. Switch should be activated by fully extended prop. (Figure 4).
10. Before operating the VS dockleveler, the maintenance locks must be moved to the
unlock position (See Figs. 4&5).
11. Although every effort has been made to purge all air from the hydraulic system, it is
possible that air may have been introduced during shipping and/or installation. The first
several operating cycles of the dockleveler should be done with the lifting mechanism
attached. Caution must be used to maintain slack in the lifting mechanism to assure
proper dockleveler operation.
12. Operate the dockleveler several times to purge any air that may have entered system
during shipment.
13. Unhook lifting mechanism.
WARNING
VS dockleveler must be
held in place by a vertical
hoist until installation is
complete and unit is
ready for operation.
