Electric Hoist Bridge Crane What are the safety technical operating procedures?

Bridge cranes (including electric single-beam, double-beam wire-controlled, and operator-operated bridge cranes) can only be operated by personnel who have obtained special equipment operation certificates issued by the relevant departments and have passed the assessment. So, what are the safety technical operating procedures for electric hoist bridge cranes?

What are the safety technical operating procedures for electric hoist bridge cranes?

1. Operators shall wear and use personal protective equipment as stipulated.

2. Operators should understand the performance, use, and safety matters of the host computer, be able to correctly operate and maintain the equipment, and be familiar with various hanging knowledge and command signals.

3. Basic requirements for operators; under the premise of strictly abiding by all rules and regulations, they should be stable, accurate, fast, safe, and reasonable.

4. Before operation, operators should: strictly abide by the handover system and complete the handover work. Before operation, inspect the crane. After confirming that everything is normal, the electric door can be sent, gas tests can be conducted on each mechanism, the reliability of various safety devices can be checked, and records can be made in the handover book.

5. Operators should do the following during work: When the crane starts, when the crane approaches, when the load is reduced, ground personnel should issue warning signals when equipment malfunctions occur. Limiters are not allowed to be used as power-off means. It is strictly forbidden to hang objects from the top or stay on people. Suspended objects should move along safe passages. Strictly abide by the "Ten No's": unclear command signals, unauthorized command not hanging; overload not hanging; when the workpiece is buried underground or connected to the equipment; the light of the lamp is unclear; there are no protective measures without protective measures; unless there is an emergency, it is not allowed to confront the vehicle. During operation, there should be a dedicated person to command, but any stop signal issued by anyone should be immediately executed.

6. After the crane work is completed, the hook should be lifted to a higher position. The hook should be suspended in the air or suspended, and the handle should be pulled back to the zero position. Vehicle.

Electric Hoist Bridge Crane What are the common accidents?

As a lifting device that replaces manpower, the electric hoist is installed on vehicles and gantry cranes and is widely used in industrial and mining enterprises, warehousing, and docks. Its appearance has greatly improved work efficiency. However, there are advantages and disadvantages, and it is affected by various factors during use. If it cannot be discovered in time, it will cause serious consequences. The following editor summarizes several factors that cause electric hoist accidents. I hope everyone can avoid them in time.

1. Operational factors: improper hanging methods, disengagement of hooks, swinging of heavy objects or chains causing personnel to be hit; attackers violating operating procedures, such as overloading, dangerous areas, etc. As well as injuries and equipment damage caused by personnel in dangerous areas. Do not cause attributes, overload, coverage, and turning due to specifications and anchor points; improper command, uncoordinated movements causing collisions.

2. The main factors of the equipment are:

(1) Events caused by heavy equipment control system failures or safety device failures, such as braking device failures leading to heavy object impacts, pinching, etc.

(2) Accidents caused by insufficient strength, such as the tilting of the injection molding machine, because the torque exceeds its stable torque.

(3) Electric shock accidents caused by electrical damage.

(4) Accidents caused by the rails, excessive wear, or bending of the bridge crane.

3. Environmental factors:

(1) Equipment, tilting, etc. Caused by strong natural disasters such as lightning, gusts of wind, tornadoes, and typhoons.

(2) Crushing and pinching accidents caused by crowded and cluttered sites.

The above three aspects are the factors of common electric hoist accidents. I hope everyone will take care of themselves, pay more attention to checking the standards, and ensure personal safety.
