What Should You Pay Attention To When Buying An Explosion-proof Hoist?

What should you pay attention to when buying an explosion-proof hoist?

Many petrochemical, flammable and explosive, and chemical industries require the use of electric hoists. Ordinary electric hoists cannot meet the needs, so we have developed explosion-proof electric hoists to ensure that the sparks or heat generated in the crane itself and the working environment will not cause an explosion. Danger and disaster.

With the development and progress of the electronic industry, petroleum industry, various chemical industries, military industries and other industries, the requirements for the explosion-proof performance and explosion-proof level of explosion-proof electric hoists are getting higher and higher. This requires explosion-proof electric hoists to start from their own technical level and be explosion-proof. New and higher requirements have been put forward in many aspects such as performance and application scope.

-Generally speaking, the key points when purchasing an explosion-proof electric hoist are as follows:

1. The electrical components of the electric hoist should include: lifting and running motors, control boxes, control buttons, limiters, etc., all of which are self-contained explosion-proof equipment.

2. Mechanical components adopt explosion-proof measures to avoid high-temperature sparks caused by friction and impact during operation of the electric hoist.

① Inject an appropriate amount of mechanical oil into the lifting and running reducer.

② The left and right stop blocks on the limit rod and the limiter sockets of the limiter are made of bronze-plated or stainless steel.

③ Apply grease to the drum and wire rope.

3. During normal operation of the electric hoist, the surface temperature of each surface shall not exceed 110°C.

4. A good explosion-proof electric hoist should use a flexible cable power inlet.

Although the number of special explosion-proof equipment is far less than that of ordinary special equipment, once an accident occurs, the impact is far greater than that of ordinary special equipment. Therefore, the significance of special explosion-proof equipment for explosion-proof electric hoists in ensuring the safety of people's lives and property cannot be ignored. Accidents can be prevented. Through effective measures, accident hazards can be reduced to acceptable levels. For explosion-proof electric hoists, strengthening explosion-proof inspection is an effective measure. Specific suggestions are as follows:

1. Prepare special technical specifications for explosion-proof electric hoist equipment to make the inspection work scientific and standardized.

2. During the daily inspection process, special inspection agencies should pay attention to whether the inspected object is special explosion-proof equipment. If so, please contact a qualified inspection agency for explosion-proof inspection.

3. Special inspection agencies in areas where explosion-proof special equipment is concentrated should have the ability to detect explosion-proof electric hoists. Responsible for explosion-proof inspection work in the jurisdiction and surrounding areas.

4. The inspection personnel of explosion-proof electric hoists play a key role in the inspection process. Carry out special training and assessment to ensure that inspectors have appropriate explosion protection knowledge and conduct inspections in strict accordance with the requirements of technical specifications and standards.
