Applications

Explosion proof electric hoist can be used on the main I-beam track to run in straight or curve line to handle materials or installed on a fixed bracket as a lifting solution for heavy loads. Explosion- proof electric hoist also can be fixed to different applications, working with explosion proof single girder overhead travelling crane or with the explosion proof dual beam bridge crane, etc.

Advantages

• Compact structure, small size, light weight, large capacity.
• High safety and reliability.
• All the spare parts are generalized and changeable, which make hoist maintenance easy and simple.
• No spark materials are used to the outside parts enhancing anti-explosion ability of electric hoist.
• Explosion proof electric hoist is designed and manufactured according to GB3836-2000.

Features

• Lifting motor used in explosion proof hoist is fully closed tapered rotor asynchronous motor of explosion-proof motor series.
• Max torque of lifting motor is 2-3 times of full loading, ensuring the safety and reliability of explosion proof hoist.
• The lifting motor has the insulation class of B or F and the protection class is IP44/IP54.
• Explosion proof hoist adopts standardized modulus of cylindrical gears, installed with antifriction bearing, which is convenient to maintenance.
• High strength gear and gear shaft are made from heat treated alloy steel.
• Lifting reducer shell is made of high quality cast iron which is closely assembled and is dust proof.
• The lifting reducer can work reliably and high efficiency.
• The hook of explosion proof electric hoist is made of high quality carbon steel, supported in the hook beam through a single scroll thrust bearing, free oscillation.
• Hook for 5t and below loads is single slippery wheel whereas hook for 10t or heavier loads is double slide wheel.
• Explosion proof hoist use hooks with card board type structure at hook end.
• When explosion proof hoist is applied to application of explosion –proof dllCT4, the hood head will be made from stainless steel.
• Protection devices are adopted, such as, up and down traveling limiter, overloading limiter, and anti-clashing devices, etc.
• Explosion proof electric hoist can be operated through wire rope control and remote control. The explosion proof switch is safe and reliable.
