Product component and system description
The upper part
Electrical System
The electrical system mainly includes the following parts: engine control, monitoring instruments, auxiliary equipment, hydraulic system control, torque limit and safety monitoring, etc.
The composition of the electrical system: conventional electrical system and PLC monitoring system.
The conventional electrical system adopts a 24V parallel circuit, and the wiring of the electrical equipment adopts a single-wire system with negative grounding. Including power supply, start control, cab air conditioning and audio, lighting (lights), wipers, etc.
The PLC monitoring system includes the control of main and auxiliary winches, rotation, main arm amplitude change and other actions, and engine status monitoring. All actions adopt liquid proportional control technology, and the PLC logic control through CAN-bus bus technology can effectively ensure the realization of various functions of the host and fully reflect the people-oriented design concept.

Safety measures
This crane widely uses mechanical, electronic and hydraulic safety and alarm devices to ensure the safe use of the machine. Safety devices include torque limiter, slewing locking device, boom anti-flip device, lifting height limit device, boom angle limit device, anemometer, slewing warning and hydraulic system overflow valve, balance valve, etc.
Installation mode & working mode switching
In installation mode, the overwinding prevention device, boom limiter, torque limiter, etc. are not functional, which is convenient for crane installation; in working mode, all safety devices are functional.
Emergency Stop
In an emergency, pressing this button will stop all actions.
