Product component and system description
Safety measures
Anti-overwinding function
The boom head is equipped with a main hoist and auxiliary hoist wire rope anti-overwinding device to prevent the wire rope from overwinding. When the main hoist and auxiliary hoist wire ropes are lifted to a certain height, the overwinding indicator light on the display will light up and the torque limiter will stop the lifting action.
Anti-over-releasing function
The main hoist and auxiliary hoist mechanisms are equipped with three-turn protectors to prevent over-release of the rope when the drum is releasing the rope. When the main hoist and auxiliary hoist wire ropes have only three turns left, the over-release indicator on the display will light up and the torque limiter will stop the falling action.
Pawl locking device
This function is used to lock the main luffing winch to protect the boom and park it safely when it is not working.
Mechanical safety device
The slewing locking device is used for mechanical limiting of the vehicle when the crane stops; the main arm and auxiliary arm bracket anti-rollover device prevents the arm and bracket from tilting backward.
Boom Angle Limitation
When the main boom reaches the specified angle, the lifting is stopped and controlled by the torque limiter and the travel switch; when the elevation angle of the main boom is less than the specified angle, the falling is stopped and controlled by the torque limiter and an audible alarm is issued.
Lifting hook anti-drop
All lifting hooks are equipped with anti-drop plates to prevent the slings hanging on the hook heads from falling off.
Hydraulic system
Equipped with hydraulic balance valve, hydraulic overflow valve and other devices to ensure the system is stable and safe during operation.
Torque limiter system
Detection function: The torque limiter can automatically detect the angle of the crane arm and the lifting load.
Display function: Large color 7.0-inch LCD display. Display the lifting operation parameters such as torque percentage, actual lifting weight, rated lifting weight, working radius, boom length, angle, maximum lifting height, working condition code, ratio, limit angle, information code, etc. in Chinese (or English) and graphics.
Warning function: It has complete pre-alarm and overload stop operation functions. If the actual load is detected to exceed the rated load and the crane arm exceeds the limit angle, the torque limiter will sound an alarm and limit the current action.
The system has a fault self-diagnosis function.
