Explosion-proof Electric Hoist Introduction
BCD type Explosion-proof electric hoist is a third-party certification of explosion-proof electrical products, and can be used for flammable and explosive gas or flammable dust in dangerous places.
The main features of explosion-proof electric hoist are that the motor adopts explosion-proof motor, the control box adopts explosion-proof electronic control box, the operation handle adopts explosion-proof operation handle, anti-collision mark, etc.
|Explosion-proof Grade:||ExdⅡBT4 / CT4|
Applications of Explosion Proof Electric Hoist
Explosion-proof electric hoist can be used for main I-beam track, run in straight or curve material or as a heavy-duty lifting solution installed on the fixed support. Explosion-proof electric hoist can also be fixed in different applications with explosion-proof single beam bridge crane or explosion-proof double beam bridge crane.
Environmental Conditions of Explosion Proof Electric Hoist
■ Explosion proof electric hoist is applied to the environment with the elevation below 1000m, with relative humility, with the Class I, Class IIB and IIC.
■ The temperature scale of explosion proof hoist is class T1-T4 (explosion hazardous area).
■ Explosion proof electric hoist can be hanged on I beam rail, explosion proof single girder or double girder, or other fixed support for material handling, etc.
Advantages of Explosion Proof Electric Hoist
Explosion proof electric hoist from DJCRANES has the following 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 of Explosion Proof Electric Hoist
Explosion proof electric hoist from DJCRANES has the following 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 by wire rope control and remote control. Explosion-proof switch is safe and reliable.
