Product Description

Zoomlion Crawler Crane Torque Limiter

1021403704 1021500485 1021403102 Suitable for Zoomlion crawler crane 70-500 tons use

Function:

The role of the crane torque limiter mainly includes the following aspects:
1. Real-time monitoring and display
- **Parameter display**: it can visually display various parameters such as main hook lifting capacity, secondary hook lifting capacity, boom working angle, boom length, working radius, etc. in the form of numbers and graphics, so that the operator can understand the current working status of the crane at any time.
- **Status monitoring**: real-time monitoring of the crane's lifting load, boom extension length, boom working angle and other key parameters, to ensure that the operator can accurately grasp the crane's working status, and detect abnormalities in time.

2. **Warning and Alarm Function**
- **Audio-visual warning**: When the working amplitude of the crane boom is close to the working limit, or the lifting load or torque is close to the current permissible load limit of the equipment, it will emit a slow warning beeping sound, while the warning indicator light blinks slowly to remind the operator to pay attention to it
- **Audio-visual alarm**: When the working limit or load limit is reached, a sharp warning beep sound is issued and the warning indicator red light flashes sharply, clearly informing the operator of the dangerous condition so that he/she can take timely measures.

3. **Safety control and protection**
- **Output control signal**: When dangerous working condition is detected, the output control signal prevents the crane from continuing to operate in the dangerous direction, but allows it to move in the safe direction to avoid accidents.
- **Prevent overloading operation**: By accurately monitoring the hoisting load and moment, it ensures that the crane works within the rated load range, prevents damage to the crane structure due to overloading, and extends the service life of the crane.
- **Guaranteeing operational safety**: Effectively avoiding serious accidents such as crane tipping over, broken boom, broken wire rope, etc. caused by misoperation or unnoticed dangerous working conditions, protecting the operator's life and the safety of surrounding equipment and property.

4. **Data recording and analyzing**
- **Black box function**: automatically records dangerous working conditions during operation, providing a basis for accident analysis and treatment, helping to identify the cause of accidents, summarize lessons learned, and improve the level of safety management and operation standardization.
- **Data analysis and optimization**: through the analysis of the recorded data, it can understand the working condition and load law of the crane, provide reference basis for the maintenance, repair, overhaul and optimization of the operation procedure of the equipment, and further improve the use efficiency and safety of the crane.

In summary, the crane torque limiter is an important equipment to guarantee the safe operation of the crane, which is of great significance for the prevention of accidents and the protection of personnel and equipment safety.
