Product Description
XCMG crane parts lifting torque limiter HC3901
803543102 fits the following models:
QY25K5
Function:
Crane lifting moment limiter is an important safety device, its main role and function are as follows:
1. Prevent overloading and overturning
The lifting moment limiter calculates the current moment value and compares it with the preset safety threshold by real-time monitoring the lifting weight, boom angle, working amplitude and other parameters of the crane. Once the actual moment exceeds the safety threshold, the moment limiter will immediately activate the protection mechanism, cut off the power supply of the lifting mechanism or issue an alarm, thus avoiding the equipment overturning caused by overload or excessive moment.
2.Real-time monitoring and warning
The moment limiter can display the actual load, working radius, boom angle and other information of the crane in real time. When the load is close to the rated value (e.g. 90%), it will send out a warning signal; when it reaches 100% of the rated load, it will send out an alarm signal; when it exceeds 104% of the rated load, it will automatically stop the operation of lifting and increasing the working radius.
3.Intelligent management and data analysis
Modern torque limiters have intelligent functions, which can record and analyse the crane's operating data and generate reports to provide a basis for equipment maintenance and optimisation. Some of the equipment also supports remote monitoring and data transmission, which is convenient for managers to understand the real-time operating status of the equipment.
4. Improve operational safety and efficiency
The torque limiter reduces the risk of accidents caused by human error or misuse through automatic monitoring and protection mechanisms, and helps operators control crane operations more accurately and improve work efficiency.
5. Compliance with safety standards
Many national and regional regulations require lifting equipment to be fitted with a torque limiter to ensure the safe operation of the equipment. The use of torque limiter not only ensures the safety of the operator and the surrounding personnel, but also meets the relevant regulatory requirements.
6. Protecting the equipment and prolonging its service life
By limiting the torque, it avoids damage to the equipment due to overload or over-torque operation, reduces mechanical wear and fatigue, thus prolonging the service life of the equipment and reducing the maintenance cost.
Working Principle
The working principle of the torque limiter is based on sensor technology and intelligent control algorithm. The sensor collects the crane's lifting capacity, boom angle and other parameters in real time and transmits the data to the controller. The controller calculates the current moment value and compares it with the preset safety threshold, and immediately triggers the protection mechanism once it exceeds the safety range.
In conclusion, the crane lifting moment limiter is an important device to ensure the safety of crane operation, through real-time monitoring, early warning and protection mechanism, effectively prevent accidents from occurring, and at the same time, improve operational efficiency and equipment life.
