TATA | Hoistractor

Requiring only two pendant levers to control horizontal movement, forward and reverse, this drive feature utilizes a drive wheel that is normally disengaged from the beam, allowing free movement of the load. When either the forward or reverse lever is depressed, the drive wheel is automatically moved into engagement with the beam by means of an air cylinder. Upon engagement, the load will move in the corresponding direction until the lever is released. When the lever is released, the drive wheel gradually disengages from the beam; this action will slow the horizontal movement of the load somewhat, before coasting to a stop. Because the drive wheel is normally disengaged, this type of drive allows the operator to manually position the load.

Odd number of levers only

Requiring at least three pendent levers for operation, one to engage the wheel, and two to control forward and reverse horizontal movement, this drive feature utilizes a drive wheel that is normally disengaged from the beam, allowing free movement of the load. To advance the Hoistractor the operator must depress one lever to move the wheel into engagement with the beam, and a second lever to impart horizontal movement. The load will continue to move along the beam as long as both levers remain depressed. If the movement lever is released while the beam engagement lever remains depressed, the Hoistractor brake will engage, and the unit will come to an immediate stop. However, if the beam engagement lever is released before the motion lever, the drive wheel will move out of engagement with the beam, and the load will coast to a stop.

This drive type allows greater control over the horizontal movement of the load because the operator manually controls the engagement of the drive wheel with the beam
