This manual provides current information on the
PowerHold vehicle restraint. Due to ongoing product
improvement, some parts may have changed, along
with operation and troubleshooting methods. This
manual describes these changes where applicable.
The PowerHold vehicle restraint is designed to seek,
find and maintain a tight, continuous hold on the RIG
(Rear Impact Guard) bar, e󰀨ectively eliminating “trailer
creep”. As an optional safety feature, the dock leveler
and vehicle restraint can be interlocked, preventing
operation of the dock leveler until the hold engages
the RIG (RIG bar).
The vehicle restraint is firmly anchored to the drive
way approach or the building wall for maximum
holding power. The PowerHold restraint is designed to
withstand a pulling force of 30,000 lbs.
The PowerHold vehicle restraint comes equipped
with an electrical control panel, which allows push
button operation of the vehicle restraint functions.
When combining a Poweramp Dock Leveler with a
PowerHold vehicle restraint, the control panel will
allow for operation of both units in the same control
panel.
Each PowerHold vehicle restraint unit and control
panel has been factory pre-wired and tested to ensure
satisfactory operation.
To illustrate which connections are to be made in the
eld at installation, electrical drawings are included
with each order or by contacting Systems, LLC
Technical Services.
Call Systems, LLC to discuss available voltages,
phases and options to meet your specic needs.

clean up the oil leaks and spills before proceeding
with grinding or welding.
Always keep a fire extinguisher of the proper type
nearby when grinding or welding.
Only trained installation professionals with the
proper equipment should install this product.
Always post safety warnings and barricade the
work area at dock level and ground level to prevent
unauthorized use of the dock leveler before
installation is complete.
A hard hat or other applicable head protection
should always be worn when working under or
around a dock leveler.
Always stand clear of platform lip when working in
front of the dock leveler.
It is recommended and good safety practice to use
an additional means to support the dock platform
and lip anytime when physically working in front of
or under the dock leveler. This additional means
may include, but is not limited to a boom truck, fork
truck, stabilizing bar or equivalent.
