Safety management system of single girder bridge crane

Many companies that have installed single-beam bridge cranes lack a complete system for crane management. Our editor has compiled a safety management system on the Internet and shared it with you. You can use it for reference based on your own situation. The full text is as follows:

In order to strengthen the management of crane machinery (single beam bridge crane) and ensure the normal operation and safe production of crane machinery (single beam bridge crane), this system is specially formulated.

2. Scope of application:

This system applies to all the company's single-beam bridge crane users and single-beam bridge crane management personnel.

3. Management responsibilities of single-beam bridge cranes:

1.  The production department is responsible for outsourcing training of personnel using single-beam bridge cranes.
2.  The equipment maintenance department is responsible for the maintenance of all the company's single-beam bridge cranes.
3.  The workshop director is responsible for supervising the work of the single-beam bridge crane in the workshop, and at the same time is responsible for the management of the single-beam bridge crane of the department under its jurisdiction to ensure its intact state, and the failure should be reported to the maintenance department in time.
4.  Drivers of single-girder bridge cranes must study the safety operating procedures of single-girder bridge cranes and pass the examination before they can operate single-girder bridge cranes independently. The crane is operating correctly.

4. the use procedure of single-beam bridge crane:

4.1 Qualification requirements:

4.1.1 Personnel using single-beam bridge cranes must be trained by the labor department and obtain a single-beam bridge crane driving license before they can work. Unlicensed personnel are strictly prohibited from using single-beam bridge cranes.

4.1.2 Without the arrangement of the production department, the personnel dedicated to the single-beam bridge crane are not allowed to teach others to use the traveling single-beam bridge crane without authorization.

4.2 Check before starting

• (1) Check whether there is oil leakage in all departments of the equipment, and deal with it in time;
• (2) Check whether each department of the single-beam bridge crane is faulty, and pay special attention to whether the brake is flexible and reliable;
• (3) Check whether the control handles of the single-beam bridge crane are in the specified position and whether the operation is sensitive and reliable;
• (4) Check whether the transmission system, lubrication system, and electrical equipment are in good condition, whether the guide rail surfaces are clean, whether there are idlers or foreign objects on the single-beam bridge crane, if the main accessories such as the controller, limiter, electric bell, and emergency switch fail, Lifting is strictly prohibited.
• (5) Check whether the safety protection devices are firm and reliable;
• (6) Check whether the steel rope is damaged, whether the steel rope has come out of the pulley, whether the hook nut is loose, whether the hook shaft pin is deformed;
• (7) Check the operation and lubrication of the empty vehicle;
• (8) After all parts are normal, the bell or warning signal can be issued before starting work.

4.3 At work

• (1) Pay attention to the working conditions and lubrication conditions of all parts of the crane, and if there is abnormal shape or abnormal response, stop and check until the abnormal shape or abnormal noise is eliminated;
• (2) Strictly abide by the principle of "ten no hanging", namely:
  • ① No one is under the command and does not hang;
  • ②The rope is not hung when knotted or broken;
  • ③Unclear gestures;
  • ④Do not hang diagonally;
  • ⑤ Do not hang when overloaded;
  • ⑥ People stand on the hanging objects without hanging them;
  • ⑦Unfastened objects are not hung;
  • ⑧The situation of the hanging objects buried in the ground is unknown and not hanging;
  • ⑨There is someone under the hanging object or the hanging object crosses the head without hanging;
  • ⑩The ladle solution is too full to hang;
• (3) Try to avoid heavy objects suddenly raising the ground. When lifting, you should first lift the heavy object from the ground about 100-150 mm, until you are sure that all lifting devices are normal and free of jams, and the braking is reliable and effective, then you can continue to lift;
• (4) It is strictly forbidden to use the limit switch to cut off the current under normal operating conditions;
• (5) It is strictly forbidden to apply reverse braking to each organization:
• (6) In the event of a sudden power failure or a sharp drop in line voltage, all controller boards should be quickly (turned) to the zero position and the main switch should be cut off;
• (7) When the single-beam bridge crane is running, it is strictly forbidden for people to go up and down, and it is also forbidden to perform maintenance and adjustment of parts during operation.
• (8) Must follow the instructions of the hook lifter (one person). During normal lifting, multiple people are not allowed to command, but for any emergency stop signal, stop immediately.
• (9) The single-beam bridge crane operator must be able to operate after receiving the command signal, and the single-beam bridge crane should be mingling first when starting.
• (10) When operating the controller handle, first shift from the "zero" position to the first gear, and then increase or decrease the speed step by step. When reversing, you must first turn back to the "zero" position.
• (11) When work is stopped, no lifting objects are allowed to stay in the air. During operation, when there are people within the moving range of the object to be hoisted or when the hanging parts are dropped, a bell should be sounded to warn. Do not leave the ground too high.
• (12) When approaching the hoisting limiter, large and small cars approaching the terminal or encountering adjacent traffic, the speed should be slow. Reversing is not allowed to replace the brake, the limit replaces the parking, and the emergency switch replaces the ordinary switch.
• (13) Walk and go up and down on the specified safe walkways, special platforms or escalators. The two sides of the cart track are not allowed to walk except for maintenance. It is strictly forbidden to walk on the trolley track, and it is not allowed to cross from one single beam bridge crane to another. A single-beam bridge crane.
• (14) When two single-girder bridge cranes hoist an object at the same time, they should be reasonably distributed according to 80% of the crane's rated load, unified command, consistent step, and steady hoisting. It is strictly forbidden to overload any crane.

4.4 After work

• (1) Raise the hook to a certain height, stop at the designated position, place the controller handle at the "zero" position, pull down the switch handle of the protective box, and cut off the power supply.
• (2) Carry out daily maintenance.
• (3) Do a good job of handover.

5. Handling of violations

1.  The single-beam bridge crane user violates the above-mentioned operating rules, and the single-beam bridge crane management department will impose a penalty of 50 yuan to 100 yuan, depending on the severity of the violation, and the safety management personnel of the production department shall impose a penalty on the single-beam bridge crane department Supervise and manage the use of single-beam bridge cranes.
2.  The single-beam bridge crane management department is responsible for lax management. Depending on the severity of the situation, the safety management personnel of the production department will impose a penalty of 50 to 100 yuan on the person in charge of the single-beam bridge crane management department.
3.  Other related personnel who violate the above regulations will be fined 50 to 100 yuan by the management personnel of the production department depending on the severity of the violation.

Single-beam bridge cranes are large-scale equipment, and their safe use can ensure the normal and orderly production of enterprises. Everyone must pay attention.
