Safety precautions of small crane during operation

Let's share the safety precautions of small cranes during operation.

Steps/methods

1. Anyone involved in the construction must be familiar with the hoisting method and project content, carry out the construction according to the requirements of the scheme, and strictly implement the rules and regulations. 2. In the process of construction, construction personnel must have a specific division of labor and clear responsibilities. During the whole hoisting process, you must seriously observe the order at the site, obey orders and obey orders, and you are not allowed to leave your post without authorization. 3. There should be a unified command signal in the hoisting process, and all personnel involved in the construction must be familiar with the signal, so that all operating posts can coordinate their actions. 4. During the hoisting process, under the command of the commander-in-chief, the whole site shall be deployed, and the deputy commanders of each post shall correctly carry out the orders of the commander-in-chief, so as to achieve rapid and accurate signal transmission and carry out their duties. 5. In the whole construction process, the site should be cleaned and obstacles removed to facilitate operation. 6. In the process of construction, all personnel involved in climbing operations must pass the physical examination, fasten their seat belts and tie them in a safe place. Tools should have safety ropes, and it is not allowed to throw things down at will. 7. Construction personnel must wear safety helmets. In winter construction, put down your ears to protect your hearing. 8. Live welding wires and wires should be far away from wire ropes. The distance between fire lines shall be kept at least 2m, or a protective frame shall be provided. When the welding wire passes through the wire rope, it should be separated and not allowed to touch. 9. Before hoisting construction, contact the local meteorological department to understand the weather. Generally, it is not allowed to work in rain, snow, open air or at night. When necessary, anti-skid and adequate lighting measures must be taken. At the same time, with the approval of the leaders, it is forbidden to hoist when the wind force is greater than 6, and it is forbidden to hoist large equipment when the wind force is greater than 5. 10: If it is necessary to bind the rigging to the structure during construction, it must be inspected and can withstand it safely, and it can only be used after approval. At the same time, a protective layer should be added to ensure that the structure and rigging will not be worn. 1 1. Before hoisting, relevant departments shall be organized to conduct a comprehensive inspection according to the requirements of the construction scheme, including: (1) Whether the rigging configuration of construction machinery is consistent with the scheme; (2) Whether the concealed works have records of self-inspection and mutual inspection; (3) Whether the position of the equipment foundation anchor bolt (referring to the embedded bolt) meets the engineering quality requirements and is consistent with the screw hole of the equipment skirt or base; (4) Whether the earthwork around the foundation is backfilled and compacted; (5) Whether the construction site meets the operation requirements; (6) Whether the hoisting equipment meets the hoisting requirements; Crane online; (7) Whether the construction electricity is guaranteed; (8) Understand the division of labor, command system and weather conditions; (9) Whether other preparatory work has been implemented, such as security, ambulance, living supply and reception. Hoisting instructions can only be issued after inspection and confirmation. After the construction personnel enter the operation post, they still need to inspect the post again. If the examination is correct, they can wait for the operation. If it is necessary to hoist every other day, personnel shall be organized to defend the site. 12: Before hoisting, try hoisting to check the stress of each part, and then continue hoisting after the situation is normal; During the lifting process, it is not allowed to stay and pass under heavy objects or near stressed rigging without the permission of the on-site commander. 13. Under normal circumstances, no one is allowed to bring things up and down. Under special circumstances, when it is really necessary to take things up and down, feasible safety measures should be taken and approved by the leaders. At the hoisting site, a special area should be set up and guarded by special personnel. In addition to this project, other construction personnel are not allowed to enter. All construction commanders and operators should wear signs, and journalists without standards are not allowed to enter. 14: If the hoisting process is interrupted for some reason, measures must be taken to deal with it, and heavy objects shall not be suspended. 15: In case of an accident during hoisting, all operating posts should stick to their posts, strictly maintain the order at the site, and make records so as to analyze the causes. The hook plays the role of connecting the crane with the heavy object, so it must be maintained. Therefore, when the lifting height limiter or hook locking device of the hook fails or is damaged, it is absolutely not allowed to be used again; As for working without a license, we should investigate the leadership responsibility.
