2.Superstructure
2.1Slewing ring
Single row four-point contact ball internal tooth slewing ring, it can slew 360° continuously, roller raceway seal is water proof and dust proof.
2.2Turntable
Welded by fine grained high strength steel, with anti-torsion frame structure, has strong load bearing capacity.
2.3Hydraulic system
Mechanical control multi-way change valve control system, the main control valve is load sensitive multi-way change valve. When pressure difference between pump outlet and load pressure decreases or increases, the system will automatically change the flow of actuator such as motor, oil cylinder, etc., accordingly system heating is reduced and inching control of whole machine is improved.
Winch system has features of high speed with light load and low speed with heavy load. Free fall is adopted in elevating system, energy saving.
Fine inching control and smooth operation are available in the swing system. Oil tank capacity: about: 483L
2.3.1Hydraulic oil radiator
Connected with hydraulic system in series, with larger power, can efficiently reduce the oil temperature in the hydraulic system
2.4Control
Mechanical control, realized by 5 joysticks located in the front of seat. All motions and speeds of crane may be infinitely controlled by joysticks.

Driven by hydraulic motor, with planetary gear reducer, normally closed brake and rotation resistant rope equipped. Main and auxiliary hoist systems can be operated separately.
Main winch: single line pull is 40KN, diameter of wire rope is 14mm, length 155m; Auxiliary winch: single line pull is 40KN, diameter of wire rope is 14mm, length 90m.
2.6Elevating system
One cylinder with counterbalance valve equipped. Elevating angle: -2°~80°
2.7Slewing system
Driven by hydraulic motor, with built-in planetary gear reducer and normally closed brake. Free-sliding function is available. Stepless slewing speed regulation is available.
2.8Main boom
It consists of one base boom and three-telescoping section, torsion-resistant design, made of high strength structural steel, with bi-hexagonal cross section. Good stability in lifting operation is available. Slider clearance is adjustable. Single-cylinder plus ropes telescoping mechanism is for synchronous telescoping. Five pulleys on boom head are standard.

2.10Safety devices
Hydraulic balance valve, hydraulic relief valve, double-way hydraulic valve, etc are fitted in the hydraulic system to ensure the system stable and safe.
Hirschmann Load moment limiter system employs advanced micro-processing technology, has features of less power consumption, powerful function, high sensitivity and easy operation. LCD with large screen will show the lifting operation data, such as moment percentage, actual lifting capacity, rated lifting capacity, working radius, boom length, boom angle, max. lifting height, working condition code, parts of line, limited angle, information code, etc. by means of Chinese and graphical symbol. It has complete forewarning and overloading cutout function, as well as overloading memory (black box) and fault self-diagnosis function.
Rope end limiter is equipped in winch to prevent rope over-releasing. Height limiter is fitted on the boom head to prevent rope over-winding.
