RVB Operation
Maneuvering
To move the PowerRoll to the load, take the handle grip in hand (without depressing the throttle) and tilt
the unit back by pushing down on the handle grip until the front support roller lifts up off the ground. In this
position the device can be easily rolled around on its rear wheels. When in position to move a load, lower
the support roller until it is in contact with the ground and the drive roller is in contact with the load.
Depress the throttle gradually to smoothly move the load.
Pushing the Load Forward
Once the PowerRoll has been maneuvered into position
(just behind the cable reel, paper roll, wheel or other
cylindrical surface
) place the drive roller in contact with the surface of the load. Then twist the variable
speed throttle on the handle grip, accelerating the load at a moderate rate to full speed. If the operator
accelerates too quickly it may cause the drive roller to slip on
the roll potentially causing damage to either the product
being moved or the drive roller. The further the throttle is
twisted, the more speed and torque the unit will generate. It
is generally safest to engage the variable speed throttle
gradually so as to prevent the possibility of accelerating the
load too rapidly and rolling it beyond the intended travel
distance as a result of the momentum from a rapid
acceleration.
Pulling the Load Backward
If your PowerRoll has an SP handle with a pivoting handle
system, pulling backward is not unlike rolling forward.
Maneuver your PowerRoll to either end of the rolling load.
Swivel the handle to the outside of the rolling load and pivot
it over the top of the machine into the pulling position. It is
critical that additional caution is exercised to ensure there
are no obstacles to the operator as they walk backwards,
pulling the load with themselves. Tripping or falling while
pulling the load could result in the operator unintentionally
depressing the throttle as they fall, accelerating the load
backwards and onto themselves. To minimize the risk of
such circumstance, at a minimum the following additional precautions should be implemented:
1. The path check
ed for obstacles or other potential encumbrances to the operator’s travel.
2. The operator walking outboard of the load being rolled backwards.
3. A safety stop to be used to limit the travel of the load.
