 Short vehicle length and small turning radius provide the crane with maximum maneuverability and flexibility in narrow job sites

Excellent off-road capability
? Big ground clearance and departure / approach angle offer excellent off-road capability.

Strong gradeability
? Cummins electronically-controlled engine, automated transmission and steerable drive axlex provide reliable power output.
? Even in the condition of abrupt road resistance,the engine can also be functional. 
? Four-wheel drive, hydraulic suspension and special tires optimize the vehicle’ s drive performance to its maximum, suitable for any bad roads and job sites.

Pick-and-carry operations

? The rough terrain crane has the ability to pick and carry loads, thus improves the working efficiency greatly.
? The crane can also carry out ”On tires“ Lifts without extending the outrigger beams in narrow job sites.
? Superior pick-and-carry ability during short-distance transit can bring great convenience to the users.

Single cab design
? Single cab design with large skylight provides large field of view;
? Air-cushioned seat suits to all types of figures, which can release the driver’ s or operator’ s fatigue, thus improves the working efficiency;
