APPROXIMATE COST BREAKDOWN*:
Feel free to ask me any questions regarding these plans.I built this simple power mover out of necessity because it was always a trying experience to back up my trailer. This mover makes it easy for one person to manuver a fairly large trailer in and out of tight spaces. It was originally used on decomposed granite to move my 24 foot enclosed trailer through a 10 foot gate and next to the side of my house. I no longer have the enclosed trailer but currently use it to move my flat-bed deck trailer into and out of my tight garage.
The heavy duty version is very similar to the standard version. It provides 37 percent more force and moves 37 pcrcent slower due to different gearing. Since it moves slower it is easier to control with a heavy trailer during starting and stopping. It also has heavier axle bearings. It uses the same axle and related hardware. Either version can be made with the pneumatic tires on the rear for use on grass and other soft surfaces. To turn the mover with the pneumatic wheels you raise them off the ground using the long handle, turn the mover then set it back down in the new direction. The plans you will receive will include drawings for both the pneumatic tire version as well as hard rubber casters as on the standard mover. The cost of construction is approximately the same as the standard mover.
It both pushes and pulls with the flip of a switch, and, when you disengage the geared winch it can quickly be rolled to where you want it. The ball mount is interchangeable which allows you to match it to your trailer height. In addition, the handle rotates to a vertical position for storage (see picture).
The construction of this mover is fairly easy. Once you have all the parts you can build it in a weekend. It does require reasonable welding skills and the ability to understand mechanical drawings. There are no difficult machining operations. A chop saw or band saw and drill press are the only heavy tools required.
The mover may be used on slight inclines (up to 6 percent) but it is not recommended for heavy trailers exceeding 2500 lbs on other than flat or near flat surfaces. On loose surfaces the selection of the ball mount should be made to provide all the trailer tongue weight on the drive wheels and minimize the weight on the casters.
