A crane is a kind of lifting machinery. It is often seen in life that when using a crane, there are some safe operating procedures that require more attention. The technicians from the Yellow River of Xinxiang Crane Rental Company will introduce the safe operating procedures and safety guidelines for cranes in detail.
Safe operation regulations for cranes:
1. The crane should be operated by a full-time driver who has been specially trained to obtain a special operation operation certificate and has passed the examination of the safety and environmental management department to obtain a job permit. The crane driver should operate the lifting machinery corresponding to the operation certificate.
2. The crane driver should strictly carry out the daily maintenance work in accordance with the maintenance plan formulated by the construction site. The inspection situation, maintenance situation, work content, and handover situation should be filled in the operation and maintenance records of the construction machinery.
3. For newly installed, overhauled or altered important machinery, load tests must be carried out in accordance with the relevant provisions of crane performance tests before use. It can be put into use only after passing the test and going through relevant procedures and safety permits.
4. Crane drivers must carry out daily inspections strictly in accordance with the provisions of the “Safety Supervision and Management System for Cranes” before and after shifts, and confirm that the cranes can start work only when there are no faults or hidden dangers.
5. The crane driver and the hoisting commander should contact each other according to various prescribed gestures or signals. During operation, the driver shall cooperate closely with the lifting command and obey the command signal. But when the lifting operation is dangerous, no matter who sends the emergency stop signal, the driver should stop immediately.
6. After receiving the lifting signal from the commander, the driver must sound the signal first and then act. When lifting heavy objects, you should first interview the crane from the ground. When you confirm that the heavy objects are hung securely, the braking performance is good, and the crane is stable, continue to lift.
7. When lifting heavy objects, the hook wire rope should be kept vertical, and it is forbidden to drag the hoisted wire rope while the hook wire rope is inclined. When the hook is hung but the lifted object has not been lifted, the crane is prohibited from moving or rotating.
8. When lifting and rotating heavy objects, the speed should be uniform and stable, so as to avoid the danger of heavy objects swinging in the air. When lowering the weight, do not go too fast to prevent the weight from suddenly falling and being damaged. When lifting long and large weights, someone should pull the rope to prevent accidents caused by heavy weights.
9. When the crane is working, personnel who have nothing to do with the lifting operation are strictly forbidden to stay on the crane.
Safety guidelines for cranes:
1. The overload or the weight of the suspended object is unclear;
2. The command signals are not clear and do not hang;
3. Inadequate binding or hanging, or imbalance, may cause sliding or hanging;
4. Do not hang when there are people or floating objects on the suspended objects;
5. Do not hang the structure or parts if there is a defect or damage that affects safe work;
6. Do not hang when there are embedded objects with unclear pulling force;
7. The working site is dim, and the site, suspended objects and command signals cannot be seen without hanging;
8. Do not hang without padding between the corners of the object to be hoisted and the binding wire
9. Do not hang when tilting and lifting heavy objects;
10. The crane safety device is incomplete, unreliable and not suspended.
The above is the relevant introduction of " Safety Operation Regulations and Safety Guidelines for Cranes ". Knowing the above, I hope that when you use a crane, pay more attention to the safety operation regulations and safety guidelines for cranes.
