The Powrhitch Industrial Mover - How it works and what it does
In today's environment of continually
rising worker's comp insurance costs, all businesses are looking for
cost effective solutions for reducing potential employee injury.
Power Wheel USA has developed its Powrhitch 2 Industrial Mover to
provide that solution, in many cases for thousands less than
comparable equipment available on the market today.
Compact and reliable, the Powrhitch Industrial Mover could be just the
answer to your particular moving need.
Let's look at the Powrhitch Industrial Mover so that you might have a
better understanding of how it might be adapted to your particular
requirements.

The standard machine comes with a mounting for on
board battery power (white box enclosure at left). The standard
machine is powered by a 4,000 RPM 12 volt DC motor geared down to 10
RPM on the drive wheels. The motor and transmission are one complete
sealed unit so there are no exposed drive chains or any other type of
external exposed gearing. When moving a loaded cart of any type,
it is necessary to transfer a portion of the load onto the machine in
order for the drive wheels to obtain traction. The greater the load
being moved, the more weight is necessary to be transferred to the
machine. This is accomplished by engaging the scoop coupling to a
fabricated lifting lug which is mounted onto the cart being moved and
then cranking the red handle knob clockwise which raises the scoop |
| coupling
and in turn brings the machine to a horizontal position. Normally, the
machine rests on the front drive wheels and the small rear taxi
wheels. The crank is designed for
transferring a portion of the load to the machine. It is not designed
to function as a lifting device to completely raise one end of your
cart off the floor surface.
The taxi wheels are for moving the machine around for when there is no
power applied to the machine. This is accomplished by pushing down on
the control handle in order to raise the drive wheel tires off the
floor surface. Then you simply push it to where you hook up to the
cart being moved.

The machine movement is
controlled by means of a rocker switch in the handle. It has forward
and reverse. Push the top portion of the rocker switch and the machine
moves away from you pushing the load. Press the switch down and the
machine pulls the load toward you. When your thumb is released, the
switch goes to the neutral or off position.
Therefore, if an employee were to trip and fall, the cart does not
keep moving but stops immediately and we feel this answers a real
safety concern. We have had some companies ask us to put another type
switch in the handle to provide constant on control but we will not
ship a machine that way. |
The Scoop Coupling
|
 |
Here is a close-up view
of the scoop coupling which is the subject we want to address now and
the necessity of having a lifting lug mounted to your carts.
The "U" shaped portion of the scoop coupling is sized to exactly hold
a piece of 2" square tubing.
The ability of our equipment pull or push a loaded cart depends on a
secure lockup between the machine and the cart being moved to prevent
any rotational effect where the scoop coupling attaches to the cart. |
Like any machine, when power is applied, the machine will follow the
path of least resistance. If it is easier to simply move out from
underneath the load, that is what will happen. However, if all of the
power of the machine is harnessed into lateral force, then this force
will move the cart or object. This is what the lifting lug and "U"
shaped tabs on the scoop coupling are designed to do.
|

 |
As can be seen in the above photograph, rotational effect is
eliminated and the interfacing between the scoop and the lifting lug
remains firm. There is enough clearance tolerance between the lug
(zinc plated object) to allow for ease of hookup but still maintaining
a rigid connection.
At the above right, is a close-up of just one type of lug fabricated
for a customer. These can be configured any number of ways to meet a
customer's requirements.
These interface lugs can be fabricated by Power Wheel USA with either
a painted finish, or zinc plated or powder coated for an additional
charge.
Our equipment functions best when the connecting point (scoop and
lifting lug) are close as possible to the horizontal center line of
the drive wheel axles of our industrial mover. The connecting point
(lug) ideally needs to be between 4" and 6" off the floor surface.
This places less stress on the drive transmission.
NOTE:
Power Wheel USA cannot be responsible for any
difficulty encountered due to worn or inoperable casters or floor
surface conditions over which our equipment is to be used that inhibit
smooth movement. It may be necessary for some or all of your casters
to be replaced if they are worn or fail to roll freely or fail to
swivel to a proper travel position..
Travel Speed
The Power Wheel USA industrial mover is available with a choice of
4 different transmission speeds, These are:
SPEED RATE OF TRAVEL*
10 RPM 26 feet per minute
19 RPM 50 feet per minute
26 RPM 68 feet per minute
30 RPM 78 feet per minute
(*) Unloaded rate of travel. As load increases, speed will drop
proportionally.
The motor remains the same so therefore torque is reduced. Less torque
(moving power) but more travel speed in terms of feet per minute.
Power Wheel USA will gladly work with you in selecting the best
combination of setup to meet your particular needs.
Solenoid vs. Soft Start
The basic Powrhitch 2 trailer mover is controlled by a heavy duty
solenoid which supplies DC power from the battery to the drive motor.
This machine is designed to absorb the shock of starting and stopping
through the hitch plate and locking collar which attaches to the
coupling of a trailer such as found on a boat and RV.
Except in a few instances, this will not work on the Powrhitch
Industrial Mover as the shock of starting and stopping can lead to a
broken transmission due to the rigid connection between the scoop
coupling and the lifting lug mounted on the cart being moved.
In lieu of a solenoid, we install a circuit board control card which
provides a soft gradual acceleration and likewise deceleration when
released.. When the handle switch is pressed, there is a momentary
delay of less than one second and then the machine builds up to normal
travel speed during the next second or two. Therefore, it takes
slightly less than 2 - 3 seconds to reach maximum travel speed
depending on how the motor ramp up time is set. This in turn
eliminates the jerk of the solenoid and provides for much smoother
operation and protects the drive transmission.
As stated previously, there are a few instances where the solenoid
starting method can be used but the weight of the object being moved
and the surface conditions governs this entirely. The use of a
solenoid start is only available for the 10 RPM transmission in a few
limited situations. The soft start control card must be used for the
19, 26 and 30 RPM transmissions.
All of our equipment is manufactured in the UK. We import the
components and perform final assembly to our customer's specifications
at our Marietta, GA facility. We distribute equipment for all of North
America.

have devised for some Fortune 500 companies and then contact us to
