Description: Electric rope hoists are suitable for medium/heavy duty operation. These are designed in modular construction with each component having easy access for maintenance purpose. The rope drum, gearbox, motor, brake and panel can be easily attended to. The frame is of sturdy design fabricated from steel plates and is welded/bolted type. Steel fabricated/seamless pipe drum is machine grooved to IS-3938 and is designed to accommodate the whole length of rope in one layer. Guide ring on the drum ensures smooth winding of wire rope. The rope guide is made of special close grain casting and is specially designed and accurately machined to suit the grooves of the rope drum, and prevents the rope from overriding and loosening. It also operates the limit switches provided as a safety feature to limit the over hoisting and over lowering of the hook. The guide is so designed to ensure proper tensioning of the rope. 6 x 36/6 x 37 construction steel rope with minimum factor of safety of 5 is provided. The complete gear train for hoisting motion is in an enclosed casing, provided with oil bath lubrication. The gears are made from alloy steel/carbon steel. A forged steel shank type hook with thrust bearing for swivel is incorporated. The hook is tested as per IS:3815. Wheel gap is adjustable for various sizes of I-beams - trolley-motor driven, hand driven, hand chain or pull push type - can be provided as per requirement. Heavy duty high tensile steel forged hooks are used and fitted in such a manner that they rotate and swivel freely. Motors are of squirrel cage induction type, conforming to IS-325 with comparatively higher HP and higher starting torque to reduce handling time. These electric rope hoists are offered by Ankita Industries and conform to IS: 3938.
