Poweramp VH SERIES HYDRAULIC - Manual (Page 18)

16 4111-0002 — January 2012 16
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, the leveler frame,
and to the front pit curb steel. Failure to do this
may result in serious personal injury or death.
16. All VH models:
a. Install shims under maintenance prop (D)
where prop attaches to leveler frame. Make
sure prop is solidly shimmed.
b. Using the appropriate lifting device, attached
to the platform lifting lugs, slowly raise the
dock to the fully open position.
A— Platform Joists
B— Shim Locations (Under Platform Cylinder Trunnions) C— Removable Frame Section
D— Maintenance Prop
INSTALLATION
Two people are required to engage the
maintenance prop: one person to operate the
lifting device, the other person to engage the
maintenance prop.
14. 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.
15. 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 Poweramp Technical
Services for further instructions.
c. Raise maintenance prop (D) to the service
(upright) position and lock prop in this
position using an OSHA approved locking
device.
d. Proceed to step 18.
