SPECIFICATIONS, SUPERSTRUCTURE 1) Main boom and telescoping mechanism 2) Jib The box-shaped main boom consists of 5 U-type boom sections made of high-strength steel. The main boom head is equipped with 5 sheaves, which is convenient for changing line parts without removing the wedges. The rooster sheave is optional. The telescopic boom sections are telescoped in / out via two telescopic cylinder and two sets of boom extension / retraction ropes. The telescopic cylinder is equipped with a plunge-jointed balance valve. Min. main boom length (with telescopic sections completely retracted): 11400 mm Max. main boom length (with telescopic sections completely extended): 43000 mm Min. telescoping out time: about 140 s It consists of two box-shaped jib sections. The jib section II is secured into the jib section I, and the whole jib is side stowed with the main boom via moveable pins during driving. A sheave is assembled at the jib head. Offset: 0, 20 and 40 Jib length: 3) Derricking mechanism 10 m 17 m Rear-mounted single derricking cylinder with derricking balance valve. Derrick angle: -3-78 Derrick speed: 4) Hoist mechanism 4.1) Main and auxiliary winches -3 ~ 78 /60s Main and auxiliary winches are equipped with the same spare parts, including double displacement axial plunger hydraulic motor and planetary reducer. An usually-closed brake is installed between the motor and reducer. The winches are driven by the hydraulic motor with planetary reducer to lift or lower the hook. 4.2) Wire rope Twist resistant wire rope Max. hoist rope strength: Max. hoist rope speed: Rope diameter: Rope length: 4.3) Hook block 70 kn 150 m/min (At the 4 th layer) Φ19 mm 200 m Rotatable main hook: 60 t, with 5 sheaves and hook latch, secured at the chassis frame in front of turntable. Rotatable auxiliary hook: 5.5 ton, with hook latch, used for the rooster sheave and jib, secured at toolbox on the chassis frame. 5) Swing mechanism It consists of cycloid motor, planetary gear reducer, pinion gear and swing bearing etc. Via the planetary gear reducer, the hydraulic motor drives the pinion gear to rotate and makes the swing bearing outer ring rotate around its inner toothed ring fixed on chassis frame, providing superstructure with 360 unlimited swing. - 4 -
Hydraulically controlled usually-closed brake, with a swing function that you can control and a pneumatic swing lockout device. Swing speed: 6) Turntable 0~2r/min High-tensile steel structure with integral mounting for two winches and bolt on counterweight. 7) Hydraulic 7.1) Oil pump Dual variable plunger pumps mounted on PTO supply oil for telescoping, derricking and hoist mechanisms; Dual gear pumps mounted on transmission supply oil for outriggers, swing mechanism, steering. Gear pumps mounted on engine supply oil for braking,pilot oil-way,and air conditioning 7.2) Control valve Use two sets of double hydraulically controlled multi-way directional valve,with mechanical joysticks. Derricking and telescoping use one set of valve,main and auxiliary winches use one set of valve. 7.3) Pipeline The hydraulics lines are a combination of tubes and hoses run through a central rotating joint. The oil cooler is located in the chassis. The indicators on the dash show the pressure 7.4) Hydraulic oil tank Capacity: 7.5) Filter about 730 L High pressure filter with the filtering accuracy of 10 µ mount on oil-ways of swinging, steering and braking. Two return-line filter with the filtering accuracy of 12 µ mount in hydraulic oil tank. 8) Crane controls The superstructure movements are controlled by two hydraulically controlled joysticks on both sides of operator s seat (comply with ISO standard requirements). The left joystick controls the swing and boom telescope / aux. winch movements (using button on keyboard to interchange between boom telescope and aux. Winch). The right joystick controls the derricking and main winch movements. The boom extend / retract pedal controls boom extension and retraction. The joysticks and the boom extend / retract pedal can provide the crane with simultaneous movements among Spool winches up, Reel winches off, Derricking, Telescope boom in / out and Swing. 9) Cab Outriggers movements can be controlled by the electrically controlled switches on the dash. There is only one cab for RT60 rough terrain crane. It can be used as operator s cab as well as driver s cab. The cab is side-mounted and adopts left hand drive. The crane adopts EATON (Ji ning) hydraulic steering gear, Yuxin (He nan) special air conditioning for vehicle and Jingwei (Beijing) special cab heater for vehicle. Exhaust emission complies with the requirements of Europe Environment Protection. - 5 -
There are two control boxes on the both sides of operator s seat. The left / right control box can be pulled up. The controls of superstructure are arranged according to the requirements of ASME B30.5-2007 standard and comply with ISO (International Organization for Standardization) standard. Cab dimensions: Length: Width: Height: 10) Rated capacity indicator (RCI) 2300 ± 5 mm 1060 ± 5 mm 1665 ± 5 mm If the actual load approaches the rated one, the buzzer sends out visual and audible warning. If the actual load reaches the rated one, all dangerous movements are switched off automatically. The rated capacity indicator also can limit the working range (including working radius, boom angle, lifting height and swing range etc.). The following information can be displayed on the screen: Boom angle or moment ratio; Boom length or default hook weight; Actual working radius or swing angle; Actual lifting capacity; Max. permissible lifting capacity; Offset or line parts; Boom status indication; Outrigger status (completely extended, intermediately extended or completely retracted or On Tires indication. The following information is displayed by bar graph: Percentage of actual lifting capacity to the rated one or working pressure of the hydraulic. 11) Outriggers H-type outriggers, hydraulically controlled, can be operated in the cab simultaneously or independently. Each vertical jack cylinder is equipped with a two-way hydraulic lock to ensure that outriggers are secured reliably during working or driving. Outrigger boxes are directly welded onto the chassis frame. The outriggers can be completely extended, intermediately extended or completely retracted for crane operation. Outrigger spread (Height): 6900 mm Outrigger spread (Width): 6900 mm (fully extended) 4830 mm (half extended) 2760 mm (fully retracted) - 6 -
