Electric Wire Rope Hoists

Elephant Brand Wire Rope Hoists are superb combination of material and latest technology.

High Efficiency: These are designed for high speed operation to increase productivity. Precision workmanship of all components minimizes losses and increases efficiency.

Short Operation: Smooth operation is ensured by gears having precision machine cut teeth subjected to heat treatment. Hoists are provided with antifriction bearings on all high speed rotation parts.

Ease of Maintenance: All parts of the Hoists requiring maintenance are made easily accessible. Number of parts requiring frequent maintenance is kept minimum. Wearing parts can be easily removed and replVenusd thus reducing down time.

Rigid Inspection: Stern inspection procedures at all stages of manufacture ensure unfailing dependability. Specific Design Advantages of "elephant brand" wire rope electric hoist.

Design: Hoists are designed for all classics of application as per IS-3938. Standard design is for class II.

Modular Construction: Hoist is assembled from different independent units viz. Hoisting Gear Box, Hoisting Motor with brake, Rope Drum, Electric Control Panel and Traveling Trolley. All these units are separately accessible and promptly disassembled cost and downtime.

Main Frame: M.S. Plates are fastened with number studs to withstand the load of the different independent units attached to it.

Wire Rope: Hoisting rope comply with the Indian standards. The leading rope taken by the Drum, does not slip sideways when slack. The factor of safety, on the nominal breaking strength of the rope is six.

Rope Drum: Grooved Drum, seamless pipe of adequate length to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum Shaft resolves on Ball Bearings for ensuring smooth running.

Rope Guide: Rope Guide is in two halves, ensuring easy accessibility. It encircles the Drum completely so that the rope may not uncoil even when the Hoist is in unloaded condition.

Motor: Hoist Motor is an HTSC parallel rotor machine. Specially rated for hoist duty, with minimum 40 % CDF rating and class B insulation. The unit is an IP 54 dust and damp proof enclosure, flange-mounted to the main frame of the Hoist. When creep speeds are required same is achieved by way of DC Clutch and pony-motor.

Gear Box: Hoist Gear Box has specially treated gears for high wear resistance. Each Geared Shaft assembly is supported on ball or roller bearings , to ensure smooth, low-friction operation. The gear trains are grease lubricated . Also oil immersed Gear Box can be provided on request.

Brake: Electromagnetic Fail-safe type brake mounted externally on the rear end of the hoisting motor ensuring easily accessibility.

Hook Block: The Hook Block is tested to 150 % of full load before assembly. The rope sheaves are fully guarded with protective steel casting . All sheaves rotate on ball bearing.

Trolley: It consists of M.S. Plates forming side frame assembled with runner-wheels. Runner wheels are mounted on double sealed ball bearings. Trolley is adjustable for various I beam sizes.

Limit Switches: A limit switch is built in as one of many safety features preventing accidental over hoisting and over lowering of the hook block. The trip positions are adjustable to allow correct setting for installation.

Electric Control Panel: Controls are mechanically and electrically interlocked to prevent inadvertent operation of opposite motions and are all housed in an IP 54 dust and damp proof enclosure . A low voltage control systems of 110 volts. minimizes electrical hazards for the operator.

Guarantee: A guarantee is provided for the repair and replVenusment, F.O.R. thane, of any part which proves defective in material or workmanship within one year of sale.
