DESIGN: Hoists are designed for all classes of application as per IS-3938.
MODULAR CONSTRUCTION: Hoist is assembled from different independent units viz. Hoisting Gear Box, Hoisting motor with brake, Rope Drum, Electric Control Panel and travelling Trolley. All these units are separately accessible and promptly disassembled to simplify repairs, reduce maintenance 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 ropes comply with the Indian standards. The leading rope taken by the Drum does not slip when slack. The factor of safety, on the nominal breaking strength of the rope is six.
ROPE DRUM: Grooved Drum, Seamless Pipe of adequate strength to be wounded in one layer and to provide proper support for the rope to minimize abrasive wear is provided. Drum shaft revolves 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 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 bailer roller bearings, to ensure smooth, low-friction operation.
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 castings. All sheaves rotate on Bearings.
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 system of 110 Volts. Minimizes electrical hazards for the operator.
GUARANTEE: A Guarantee is provided for the repair and replacement, which proves effective material or workmanship within one year of the sale on Ex. Works Basis. However electrical appliances are not covered in this guarantee.
