22M Working Height Articulated Boom Crane

● The boom head, cylinder piston rod, and other parts of the articulated boom crane are equipped with dust and sand protection devices. ● The drag chain of the articulated boom crane is made of high-strength engineering plastic resistant to marine climates, suitable for harsh working environments. Easy to Operated ● Lifting lugs of each articulated boom crane are provided on the chassis and turntable for easy hoisting. ● The working basket of each articulated boom crane is equipped with an automatic leveling function, and the tilt angle of the work basket relative to the horizontal plane does not exceed 1.5 °.

●The articulated boom crane are equipped with upper and lower control consoles (ground console and platform console) with a reversing switch for switching between them. The upper control console has a lockout function to disable the lower console. ● The boom extension, luffing, and rotation operate smoothly and are equipped with buffer devices. ● The electric self-propelled articulated boom crane adopt to hydraulic braking and mechanical parking brakes, offering simple operation, safety, and reliability. The service brake features automatic compensation, and the brake is of disc type. ● A foot switch is installed on the platform of the articulated boom crane operations can only be performed when the foot switch is pressed. ● When the machine is parked on a surface with an inclination exceeding 5 °, the boom movement by the will be articulated boom crane restricted.

● The system of articulated boom crane adopts PLC and CAN bus control, simplifying wiring and facilitating maintenance and repair. ● Boom extension, luffing, rotation, and platform movement of articulated boom crane are all controlled by electro-hydraulic proportional control, enabling step less speed regulation. ● The articulated boom crane is equipped with an intelligent charging system, utilizing a fully automatic charger that can complete the entire charging process automatically. Charging stops automatically once the battery is fully charged.

● Key hydraulic components and control elements of the articulated boom crane are imported branded products, ensuring high reliability. ● The hydraulic system features automatic pressure compensation and load sensing functions, preventing the hydraulic pump from being damaged due to overload. ● An emergency descent device is installed on the articulated boom crane, allowing the work platform to safely lower to the ground in the event of a main pump failure. ● Safety valves on the articulated boom crane are installed in the hydraulic circuit to prevent abnormal pressure increases in hydraulic components.
