General Overview
PowerHandling’s product line and features are constantly being updated and improved so please check
for more information and updates at www.powerhandling.com.
PowerHandlers are broadly categorized into two types of machines, with an optional third being
a combination of both of these:
o
those that Roll
( Fig. 1)
(such as paper rolls, cable reels or vehicles) or
o
those that Push (such as trolleys, carts etc), or
o
those that Roll and Push
(Fig. 2)
(being a rolling model with a
Hybrid or Pusher Bracket).
Beyond this distinction there are models powered by:
o
Compressed Air – having an airline connected into the back
end of the handle grip throttle; or
o
Rechargeable Batteries – having two battery packs, one on
the machine and one on a charger (so the machine is never “down” for recharging).
Further model distinctions apply according to:
o
the size and power output of the motor, and
o
the reduction of the gearing, the latter tailoring a
PowerHandler for higher torque or for higher speed to better
match the requirements of the application. In each case an
increase in one results in a corresponding reduction in the
other.
Finally, models can be further customized according to the handle assemblies and other
attachments, etc. For example ‘Roller’ models can be configured with:
o
a
C
enter Straight handle shaft (C), a
o
a
S
wiveling handle shaft (S) or a
o
a
S
wiveling &
P
ivoting handle shaft (SP)
(Fig. 3)
.
To overcome the inertia of a heavy load, PowerHandlers require a
significant amount of traction – both with the load itself and the ground
on which it’s being moved. Regardless of the amount of power (or
specifically ‘torque’) generated, the load will not move without the
necessary traction.
PowerHandlers gain this traction by directing the weight of the load down onto the drive roller to generate
the traction that is required. In the case of moving cylindrical loads, small diameter / lighter loads can in
fact be more of a problem than larger heavier loads as the weight transfer onto the drive roller is not as
good. This problem will be apparent if the drive roller is observed to slip or spin against the load rather than
wedging in under the load and rotating it. (Please refer to the “Trouble-Shooting” section for suggestions on
how to address this issue).
