Src300cr 30t Rough-Terrain Crane

Control room
With independently researched and developed ergonomics design of S.A.N. Y, sliding door, safety glass, corrosion resistant steel plate, soften interior, super-large internal space, panoramic skylight, adjustable seats and other humanization design, air conditioner and electric wiper, it is more comfortable and relaxing for operation; moment limiter display screen is equipped, which realizes organic combination of main console with operation and display system and provides open-and-shut data of all conditions during hoisting.

Boom system
▪ Boom: There are four booms, including basic boom of 9.9 m and fully extended boom of 31.5 m; they are made of welded structural steel with high strength, with U-shape section.
▪ Jib: There are two jibs of 7.7 m and 12.5 m respectively at the setting angle of 5°, 25° and 45°.
▪ Telescoping mechanism: It is subject to dual-cylinder rope row type telescopic mode, with the full extension/retraction time of 50/40 S only. The telescoping mechanism is simple, efficient, safe and reliable.

Superstructure hydraulic system
With load-sensitive variable plunger pump, it can adjust the displacement of oil pump in real time to realize the flow control with high accuracy and reduce the energy loss greatly.
▪ Electric control variable motor is used for winch, so high operation efficiency is ensured; the maximum speed of single rope of main and auxiliary winch reaches 125 m/min.
▪ With integrated slewing buffer valve, the slewing system has free trackslip function to realize steady rotary start and control, showing outstanding micro-mobility.

Lifting mechanism
With double-variable speed governing pump and motor, high efficiency and energy conservation can be realized. Winch balance valve is perfectly integrated with the unique anti-slip technology, thus weight can be lifted and dropped steadily. The anti-rotating steel wire rope of high strength is provided to realize accurate lifting and positioning. The steel wire ropes of main and auxiliary winches have the same diameter of 16 mm and the length of 175 m and 105 m respectively
