Screw drive for Tipper/Dump truck..

[Lmackattack]

The motor / gear reduction u it is mady by Carson. I'm not sure of the gear ratio but it simply works off a speed controller tucked in the frame. It's controlled by a 3 position switch on my radio. It's perfect for a tractor dump set up. Plenty of power for its size. I used a u joint to turn the screw drive lift. This way the motor can be solid mounted into place and the u joint takes up the angle change as the box raises and lowers. Word of warning ...I don't feel this Carson motor / lift has the needed power to lift a heavy loaded trailer box.. It will lift a tractor size bed but not a longer trailer bed...

Here is the link to the Carson motor.
