  • Page 13: Suspension Types

    Electric Chain Hoist Operator’s Manual/EN/11.30.10 Electric Power The hoisting motion (lifting or lowering) of an electric powered hoist is initiated when the operator grasps and activates a control device. The control device has push buttons that energize, through a series of contractors and other electrical components, an electric motor.
  • Page 14 Electric Chain Hoist Operator’s Manual/EN/11.30.10 Trolley Mounted Trolley mounted hoists are hook mounted or lug mounted hoists suspended from a trolley; or a hoist having an integral trolley as part of the hoist frame, that allows travel motion on the lower flange of a monorail beam, or the lower flange of the bridge beam of an overhead crane.

  • Page 15: Directional Travel Of Overhead Hoists

    Electric Chain Hoist Operator’s Manual/EN/11.30.10 Directional Travel of Overhead Hoists Hoist motion is the vertical travel motion direction of the hoist load hook. The hoist operator should be familiar with the hoist (or crane) controls and understand what type of motion will occur when any one of the control devices is activated.
  • Page 16 Electric Chain Hoist Operator’s Manual/EN/11.30.10 All motions of multi-speed powered hoists should be started in the slowest speed available for that motion, and then the speed should be increased until the desired speed is obtained.
