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
 
Click to enlarge. 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.
