Recently, 2 units 55 ton rough terrain crane were delivered to customer by sea.

High lights of RT55E Rough Terrain Crane

Developed jointly by Chinese and German engineers, it leads the industry technology tendency. With advanced design concept introduced, perfect product is built with the longest boom, highest lifting capacity and power performance compared with products in the same class.

Three operating modes: superior performance of operation on outriggers, which is not less than that for truck crane in a stationary site; unique performance of operation on tires makes it easy to complete the job what truck crane could not finish when it is difficult to deploy outriggers in a confined site; powerful pick and carry capacity makes fast operation of lifting and transferring load. It is suitable for lifting and transferring operation in oil patch, storage, goods yard, dock and logistic base, etc.

Two driving modes: forward and reverse driving function contributes to fast transferring within a site or from a site to another; four electro-proportional steering modes combined with min. turning radius of 5.7m offers unmatched maneuverability in a confined space. Specialized off-road tires and super power system ensure favorable off-road capacity, suitable for applications in various adverse sites. 

Cummins electronically controlled engine (Off-road：U.S.EPA Tier 3/EU Stage IIIA), ZF automatic transmission, KESSLER axles are matched optimally, contributing to distinguished power performance; the hydraulic system from Rexroth designed for the product has good applicability and reliability; CAN bus control system, fault diagnostic system and warning devices ensure safe and efficient operation.

Cab of integrated design is simple and artistic. All-weather cab has a wide field of view and sliding doorsaving space and facilitating operation. It is spacious and comfortable due to ergonomic inner design.Damping suspension seat with high backrest may be adjusted according to operator’s body, and can reduce operator fatigue and optimize productivity. Air conditioner and heater are equipped in the cab. Large screen color display combined with main control panel makes operation convenient and easy, and the operating parameters and working conditions may be seen at a glance.  

Swing, rigidly lockable hydraulic suspension technology: the shock absorption function of rear suspension may be performed through the swing mechanism and suspension cylinder when driving on roads, consequently road shock is buffered and travel smoothness is improved; the rear suspension cylinder may be locked to rigid state so as to meet the requirement for travel with a load suspended; during operation of crane on tires, when the turntable is turned over ±3°, suspension system may automatically switch over to rigid state, operation safety is ensured.

Switch over of wheel turning direction: when the vehicle is driving while the turntable is turned over 90°, the control system will send a signal through the position sensor fitted on the turntable for controlling the hydraulic change valve between the steering wheel and the change cylinder of front axle. And then the vehicle drives in reverse direction, and the rotating direction of the steering wheel is the same as that for forward driving.

Automatic low pressure brake technology: with full hydraulic double circuit disc brake fitted, the brake is engaged automatically when the pressure in braking system is lower than the setting, thus driving safety is insured.
