Hydraulic system
The crane adopts a series-connected hydraulic system with hydraulic pilot proportional control. The high-speed hydraulic motor drives the planet reducer to realize movements of the mechanisms.
The system has such advantages as high efficiency, energy-saving, smooth and safe simultaneous movements.
The oil cooler for hydraulic system: a radiator driven by high-power hydraulic motor, 40 kW
Hydraulic oil tank capacity: 770 L
Electrical system
24 Volt DC, negative ground, two batteries of 200AH each.
The electrical system of the crane includes the power supply, engine start, engine shutdown, indicator lights, warning devices, illumination devices, fan, wiper, horn, hoisting limiter, hydraulic oil cooling fan, concentrated display panel, load moment limiter, safety devices etc. which not only ensure safe operation of the crane but also provide a good working environment.
Counterweight
A tray-type assembly structure is adopted for the counterweight system. The counterweight plates are stacked up, and locked by the hydraulic oil cylinder.
The counterweight is 2.98 m wide, which is easy for transportation.
The movable counterweight consists of four counterweight plates, i.e. a counterweight base plate (8 t), a middle plate (8 t) and two side plates (2 t each); whose total weight is 20 t.
