Requirements of cantilever cranes for working environment

Cantilever crane is a kind of light and small lifting equipment, which can greatly reduce the work intensity of workers and improve work efficiency. Cantilever cranes generally use 380 volt three-phase power supply and cannot be used in flammable and explosive environments. The editor briefly introduces the requirements and operating procedures of the cantilever crane for the use environment.

The environmental requirements of cantilever cranes are as follows:

1. The power source of the crane is three-phase AC, the rated frequency is 50HZ, and the rated voltage is 380V.

2. The altitude of the crane installation site does not exceed 2000M.

3. There must be no flammable, explosive and corrosive gas in the working environment of the crane.

4. Cranes are not allowed to lift molten metal, toxic materials and flammable and explosive materials.

Safety operating regulations for cantilever cranes :

1. The operator of the cantilever crane should check the switch button and wire rope limit before use for any faults. If there is any problem, it must be repaired in time before it can be used. After use, the power switch must be turned off before leaving.

2. Concentrate when lifting the workpiece, put your hands on the operating switch, so as to brake at any time, and do not chat or eat while lifting, so as to avoid danger.

3. When hoisting any workpiece, be sure to try the hoist. The hook should be vertical. If it is found to be unbalanced, adjust the hook in time. Do not hoist obliquely. Re-try the hoist to keep the workpiece stable before hoisting.

4. Over-load lifting is not allowed, and lifting any workpiece is not allowed to exceed the rated lifting weight, otherwise, heavier punishment will be imposed according to the violation of operating regulations.

5. When lifting the workpiece, it is not allowed to be too high from the ground. It should be about half a person's height. If there is an object over it, be careful not to collide, and it is forbidden to lift it across the machine tool.

6. When lifting any workpiece, you should pay attention to the operating conditions at all times, stop the lifting immediately when abnormal noise or abnormal phenomenon occurs, and report and deal with it in time. If you work with illness, you will be severely punished according to the operating procedures.

7. All surprise repairs are strictly prohibited when the cantilever crane is in use.

8. When not in use, the jib crane should be placed in a safe place. It is not allowed to obstruct the operation route of other lifting equipment, and it is not allowed to park at will. Otherwise, it will be punished according to the operation regulations.

Cantilever cranes are simple to use and easy to operate. They are essential equipment for many companies to reduce work and improve efficiency in workshops.
