Kinematics slewing drives are powered with hourglass worm technology for maximum gear torque and the smoothest rotation. Typical slew drive applications include truck cranes, man lifts, utility equipment, hydraulic attachments, oil tool equipment, marine cranes, tire handlers, digger derricks and automotive lifts, but the slew drives are used in many other applications requiring load holding and rotational capability. We offer different slew drive models with moment load capacities of 5,000 to 200,000 ft-lbs.
