IMPORTANT SAFETY NOTE:
The PowerRoll does not in itself “control” the load it moves. It rolls the load forwards
but without braking or controlling that movement. Therefore, precautions must be
taken to ensure the load does not roll forward further than intended, causing damage
or injury to others. Use of a safety stop is one recommended procedure. Note that
whatever method is used, the onus of safety is on the operator to ensure there are no
risks involved with the intended move.
The Quick-Charge / Quick-Change Battery Concept
Battery powered PowerRoll
s operate on the principle that most of the battery capacity is ‘off
-
machine’ and
can
be recharging while a smaller amount of the battery
capacity is ‘on
-
machine’ and being used. This
principle
allows the PowerRoll to be significantly more compact than conventional materials handling machines of
comparable torque / load moving capacity.
Therefore, it is important to locate the charger and second battery pack as close as possible to the area in
which the PowerRoll
will be used. This will minimize the operator’s
travel time to switch-out battery packs
and therefore improve not just convenience but also performance and efficiency.
Installation of the Charger
PowerHandling’s smart c
hargers are custom designed and built to operate only with PowerHandling battery
packs. Do
not
use a different charger for a PowerHandling battery pack and do
not
use a different battery
pack on the PowerHandling charger.
A thermistor on the battery pack provides feedback to the
charger on the temperature of the cells during the charging
process, allowing the charger to ensure it does not overheat
(over-amp) the pack during the charging process.
The AC input can be from any properly grounded wall outlet
worldwide, handling from 100V-240V and either 50 or 60 Hz.
If the power supply is not “clean” however, consider using a
UPS, or line filter to prolong the life and improve the
performance of the charger.
General Throttle Operation Guide
The RVB model of PowerRoll is equipped with a variable speed throttle which allows the operator to engage the
drive roller to the load to be moved and gradually accelerate it to full speed / full throttle.
The purpose of the variable speed is to accelerate the load gradually, which:
a) Reduces the likelihood of slipping or traction loss between the drive roller and load;
b) Reduces the likelihood of tearing or damage to either the product or the drive roller;
c) Reduces jarring or lurching of the load, which is safer in respect to maintaining control of the load and better
for the machine, as it reduces peak amp draw which extends both battery life and motor life.
