- Maneuverable and robust drive
- Four-wheel drive and four-wheel steer chassis
- Fully hydraulic steering system
- Variable steering modes, front-wheel steer, four-wheel steer and crab steer
- 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 axle 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
- The crane is fitted with air conditioning, suitable for all-weather work
- Digital display and keyboard units, advanced data bus technology, error check and audible & acoustic alarm ensure the safety and high efficiency of the operation
