The lifting machinery should be marked with distinctive colors to identify the size and quantity of components excluding stabilizers.

The content of the lifting machinery mark mainly includes the following aspects:

1. The name and address of the lifting machinery manufacturer.

2. The type, model and factory number of the lifting machinery.

3. The maximum rated lifting capacity of the lifting machinery.

4. The scope of use, restrictions and prohibitions of lifting machinery.

5. The main technical parameters of the lifting machinery, including working radius, main boom length, etc.

6. Marks of key components, such as main wheels, running wheels, lifting hooks, hook cables, etc.

7. Instructions and precautions for the use of auxiliary equipment of lifting machinery.

8. The factory date and factory inspection date of the lifting machinery.

The content of the logo should be clear, eye-catching, easy to identify, bright in color, and not faded or blurred. In addition, the sign should be placed in a conspicuous location for easy viewing by operators.

In addition to the mentioned sign content, the lifting machinery should also be marked with the following aspects:

1. The size and number of the stabilizers of the hoisting machinery. The stabilizers are the lifting equipment. An important part of machinery that can improve the stability and safety of lifting machinery.

2. The rated working pressure of the hydraulic system of the hoisting machinery and the amount of oil required per unit time, as well as the oil replacement cycle and method.

3. The rated voltage and current values ??of the electrical system of the lifting machinery, the specifications and length of the cables used, the number and location of cable joints, and the type and usage of the remote control.

4. General maintenance and maintenance methods of lifting machinery, as well as troubleshooting methods under special circumstances.

The content of the lifting machinery signs should be as complete and accurate as possible. At the same time, attention should be paid to the update and maintenance of the signs to ensure that the signs are clearly visible to improve the safety and reliability of the lifting machinery.

Precautions for crane signs

1. Accuracy of sign content: The content of the sign must be consistent with the actual situation, and there must be no false or wrong information, otherwise it will mislead operators and increase Risk of accidents.

2. Selection of logo color: The color used for the logo should be eye-catching, bright, not easy to fade, and should be different from the main color of the lifting machinery to avoid confusion.

3. The location of the sign: The sign should be placed in an easily visible location and should correspond to the relevant parts of the lifting machinery so that the operator can quickly find the correct sign information.

4. Modification and update of signs: The signs need to be modified and updated according to the actual situation of the lifting machinery, such as changes in rated lifting capacity, updates of maintenance and upkeep methods, etc., to ensure that the content of the sign is always accurate reliable.

Marks are an important part of lifting machinery and play a vital role in the safety and reliability of lifting machinery. Therefore, operators should read the signs carefully and abide by the signs to ensure the safe operation of the lifting machinery.
