ROTAHOOK

The "ROTAHOOK" is tough; with an ample design factor to withstand abuse and handle severe overloads. Heavy bumper plates prevent damage to the internal mechanism from rough treatment. A slip clutch protects the gearing from damage when the load hits an object in transit or while swinging. Forged steel sheaves have hardened rope grooves, or are heat treated to specification.

 

Special Features of the "Rotahook" drive unit are as follows:

  • Disconnect clutch on reducer to enable disengagement of hook drive for manual rotation in case of power failure.

  • Carburized and hardened bevel gearing.

  • Drive is protected by heavy duty springloaded disc slip clutches.

  • The complete drive unit is a modular design (unique to Drafto) and easily separable from the main housing. The upper half of the block does not need to be unreeved from the crane when changing the drive or hook.
