Its performances such as lifting height, boom length, working speed and lifting capacity have achieved advanced international level. The truck crane, with spacious cab and luxurious equipments, adopts full slewing system, telescopic boom, electro-hydraulic proportional control system and self-made full-width special purpose chassis with four axles. 8×4 drive and hydraulic power steering mechanism provide the crane with good driving performance and flexible steering. The system with latest load feedback electro-hydraulic operated proportional directional control valve and double pump is adopted to make full use of the working capacity of each actuating mechanism. The control type of 2 levers, which are flexible and stepless speed regulated, can carry out any of the 2 crane movements “Spool up main / auxiliary winch”, “Reel off main / auxiliary winch”, “Telescope boom in / out”, “Derrick”, and “Slew” simultaneously. All that not only provides the crane with stable and reliable simultaneous movements but also greatly improves crane’s working efficiency. The safety devices fitted in hydraulic system, such as relief valve, balance valve, hydraulic lock and brake valve etc., prevents the oil line from overloading and the accidents caused by oil pipe breakage. The control system adopts modern data bus technology and has fault self-diagnosis function. LCD can display the pressure on fault point in real time and provide the troubleshooting methods. The safety devices such as load moment limiter, and the complete lighting system equipped in the crane ensure your safety during operation and are convenient for night work. This crane has a novel style which makes it beautiful in figure, in form and in color.___________________________________COMPONENTS & PARTSNew sliding design for bracing support, side hydraulic lock Anti-slew steel wire Moment Limiter and Display Major boom head and slider Hydraulic Motor
