When the wire rope explosion-proof electric hoist can be used in the workshops with the explosive mixtures in the workshops. it is a favorable tool to improve working conditions and improve labor productivity under the premise of ensuring safety. It is a necessary hoisting equipment for production to help improve material handling efficiency. The working environment temperature of explosion-proof wire rope electric hoist is -25℃~40℃, which is suitable for indoor use; when the explosion-proof hoist is used outdoors, protective devices are required.

Inspection before leaving factory:

• Each explosion-proof electric hoist can only leave the factory after the factory inspection and test requirements are qualified . As for customized explosion proof electric hoists will be inspected carefully in terms of the user's special requirements and unique features.  All the electric hoist delivered before leaving factory should be accompanied by a product qualification certificate.
• Check whether the explosion-proof electrical equipment selected for the explosion-proof hoist has an "explosion-proof certificate". Check the type, grade and temperature group of explosion-proof electrical equipment according to the design drawing of explosion-proof hoist, and check the correctness of its installation.
• Check the records of the implementation of 6.3~6.5, 9.1 and 9.2.
• The rest of the inspection contents shall be inspected according to the inspection items of JB/T 5317 or JB/T 9008.2.

Technical date of wire rope exploison proof electric hoist

A ttention: Prohibition of inclined position, prohibition of excessive load, prohibition of hanging people, prohibition of people below during the operation of the electric hoist, and prohibition of changing the factory configuration of the electric hoist by yourself.

Classification and working principle of explosion-proof electric hoist

The explosion-proof electric hoist is made of non-sparking material, with good safety and reliability. According to different application places, it can be divided into metallurgical electric hoist, BCD type explosion-proof electric hoist, explosion-proof electric hoist, explosion-proof electric chain hoist, etc.

The working principle of explosion-proof electric hoist: The safety brake for explosion-proof electric hoist is a mechanical safety device. When the lifting conical motor fails to brake, the heavy object on the hook falls freely, and the curved guide rail is accelerated to rotate through the wire rope, reel, and pawl transmission. When the guide rail accelerates to a certain speed, the centrifugal force generated is greater than the spring. The pulling force makes the roller deviate from the shape track of the guide rail, and the pawl of the safety brake meshes with the ratchet wheel, so that the drum can achieve the purpose of braking, in order to avoid mechanical sparks and ensure the explosion-proof performance of the electric hoist. Pawls and rollers are made of non-sparking material.

The explosion-proof electric hoist has the characteristics of light weight and compact structure. The equipment can reduce the strength of rest force under the premise of ensuring safety. In order to ensure the safety and reliability of the quality of explosion-proof electric hoists, each explosion-proof electric hoist of Lingying will carry out various safety inspections before leaving the factory to ensure that each inspection item is qualified before leaving the factory.

Related Explosion proof wire rope hoist

The explosion-proof electric hoist is a wire rope electric hoist that has passed the explosion-proof performance test of the explosion-proof electrical product quality supervision and inspection center of the Ministry of Machinery Industry, and issued an explosion-proof certificate. Explosion-proof electric hoist is a favorable tool to improve working conditions and improve labor productivity under the premise of ensuring safety. It is a necessary mechanical equipment for production. Common explosion-proof electric hoists can be divided into explosion proof electric hoist and explosion-proof chain hoists.

The explosion proof electric hoists can be grouped the frequently used BCD type explosion-proof wire rope hoist, the Extended type explosion-proof wire rope hoist with super lifting height from 12 -30 meters, and HB (BCD) type explosion-proof electric wire rope hoist 10 tons. The main difference between them is that the tonnage is different and the lifting height is different.

• BCD type explosion-proof wire rope hoist is a common specification, the lifting capacity: 0.5T, 1T, 2T, 3T, 5T. Lifting height: 6-9 meters.
• Super height explosion proof electric hoist - The lifting capacity of the extended explosion-proof wire rope hoist is the same as that of the BCD electric hoist, and the lifting height is 12-30 meters.
• HB (BCD) explosion-proof electric hoist (10 tons) has a lifting capacity of 10 tons.

Compared with the first two types of explosion-proof electric hoists with large tonnage, the lifting height is 9-30 meters.

6-9m explosion proof electric hoist

12-30 m explosion proof electric hoist

Explosion proof electric hoist 10 ton

The common models of explosion-proof electric chain hoists are with the rated load of 2.5 tons, 5 tons, 10 tons and 20 tons, and the standard lifting height is 3 meters. The disc brake motor is used as the power, and the planetary reducer is used for deceleration. It has the characteristics of compact structure, small size, light weight, high efficiency, convenient use, reliable braking and simple maintenance.
