Torque limiter system is a safety device installed on heavy load handling equipment to ensure its operational safety and prevent overloading accidents. The torque limiter system developed by the company is applicable to mobile cranes, tower cranes, excavators, aerial working platforms, overhead cranes and all other equipment that can be used for lifting and handling.
Through the sensor to collect the key data of the operating equipment real-time calculation of the actual load and the rated load, to send warning signals and overload signals to the operator, automatically stop the dangerous direction of the equipment action, and effectively avoid the destruction of the mechanism and overturning caused by overloading. Equipped with a special display, the system provides real-time operation data parameters for the equipment operator to ensure operational safety.
The system is based on model development and introduction of modal analysis, based on wireless technology for the measurement of system parameters, the actual load calculation is more accurate, the real debugging-free, greatly enhancing the production efficiency of the host manufacturing enterprises; high-performance combination of cloud, end, side calculation, dynamic calculation of the rated load, the equipment lifting capacity of the line surface and body of the multi-dimensional presentation of the lifting ability, lifting capacity is stronger and more comprehensive; through the function of safety certification of the system design to meet the regulatory requirements of export, Europe and the United States; vehicle-mounted crane Europe and the United States regulatory requirements; on-board lifting planning function is like a real-time online lifting expert, providing professional guidance for operators at any time, making lifting more energy-efficient, more efficient and safer.

The traditional construction machinery operation method has a strong dependence on operator experience, which not only affects the productivity and cost, but also can't be applied to the operation requirements in special environments. Combining RTK, LIDAR, millimeter-wave radar, IMU, visual recognition and other perception technologies, robot control technology, 5G large bandwidth and low-latency communication technology, we have developed a real-time positioning system for the drawing of operating maps of construction machinery and equipment, equipped with self-developed high-performance domain controller for the development of special algorithms and models, and realized the autonomous planning and decision-making of various action paths and the electro-hydraulic closed-loop precise control of the execution of the action to complete the unmanned and unmanned operation of construction machinery and equipment. The system is equipped with self-developed high-performance domain controller and special algorithm model development to realize autonomous planning and decision-making of various action paths and electro-hydraulic closed-loop precision control of action execution, and complete the unmanned driving and unmanned operation of construction machinery equipment.

Due to the transportation regulations and the life cycle requirements of the transport equipment, the transport equipment needs to count the weight of the loaded materials when loading to control overloading and underloading, and the traditional weighbridge weighing method has a lagging effect, which affects the production efficiency. The traditional weighbridge weighing method has lagging time, which affects the production efficiency. By collecting relevant information directly or indirectly through sensors, developing special calculation models, and carrying self-developed operation controllers to develop real-time weighing of loaded weights, this on-board weighing system has the characteristics of high precision, convenient installation and debugging, high reliability, etc., and the weighing values can be directly used for trade settlement, and the system is widely used in the bulk transportation weighing industry segments, such as cement, building materials, agriculture, mines, wharves, logistics and chemical industry. The system is widely used in cement, building materials, agriculture, mining, dock, logistics, chemical and other bulk transportation weighing industries.
Advantages of the system:
High precision, error less than 1%;
Easy to install, can be front or rear mounted;
