Correct use of explosion-proof electric hoist

Explosion proof electric hoist is a lifting tool used in special environments, with explosion-proof performance, suitable for lifting objects in flammable and explosive gas environments. The following are the key points for its correct use:

Understand the product manual:

Before use, carefully read and understand the product manual to understand the specifications, performance, and usage methods of the product.

Wear personal protective equipment:

Before operation, appropriate personal protective equipment must be worn, such as safety helmets, protective goggles, earplugs, protective gloves, anti-static shoes, etc., to reduce potential hazards.

Check the integrity of the gourd:

Check if the gourd itself is complete and ensure that electrical circuits, buttons, switches, and other components are working properly. If damage or malfunction is found, immediately stop using and seek professional repair.

Choose an appropriate work environment:

The use environment of explosion-proof electric hoists must comply with explosion-proof requirements and follow relevant safety operating procedures and standards.

Correctly install the hoist:

Ensure that the gourd is correctly installed on a stable bracket and that the hook has sufficient load-bearing capacity to properly connect the working object.

Safety of operators:

Maintain a safe distance and avoid standing under lifting objects. Operators should remain vigilant and avoid contact with gourds, hooks, work objects, etc.

Understand the lifting capacity of gourds:

Before use, it is necessary to understand the lifting capacity of the hoist and ensure that the object to be lifted does not exceed its rated weight. At the same time, ensure that the connection between the hook and the working object is strong and reliable.

Precautions for operation:

During the operation, the lifting and lowering of the electric hoist should be controlled smoothly and slowly to avoid sudden acceleration or deceleration.

Overloading is strictly prohibited to prevent safety accidents.

Common problems with explosion-proof electric hoists

Explosion proof electric hoists may encounter some common problems during use, mainly including:

Electrical malfunction:

Contact adhesion, adhesion or jamming of lifting contacts inside the control electrical cabinet, causing the hoist to malfunction.

Brake malfunction:

Excessive brake clearance, oil stains or wear can cause excessive braking distance or brake failure. In addition, small clearance or lubrication failure during brake movement may also cause problems.

Mechanical malfunction:

The deformation and cracking of the cone brake and motor rotor brake shaft affect the braking effect.

The height limiter malfunction caused the hoist to fail to stop at the predetermined height.

Safety protection device malfunction:

The malfunction of the lifting height limiter, damage to the lifting weight limiter, and failure of the travel limiter of the large vehicle traveling mechanism increase operational risks.

Improper maintenance:

Insufficient lubrication, severe wear, or knotting of the steel wire rope can affect the performance and safety of the hoist.

Response measures

Regular inspection and maintenance:

Regularly inspect and maintain explosion-proof electric hoists, including electrical systems, brakes, mechanical components, and safety protection devices.

Timely handling of faults:

Once a malfunction is detected, it should be immediately stopped and handled according to the operating procedures or seek professional maintenance.

Strengthen training:

Regularly train operators to improve their understanding and skills in using explosion-proof electric hoists, ensuring the safety and effectiveness of their operations.

Recording and management:

Establish a comprehensive system for equipment archives and fault records, and provide detailed records and management of equipment usage, maintenance records, and fault handling.
