  1. 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
  2. Excellent off-road capability
    • Big ground clearance and departure / approach angle offer excellent off-road capability
  3. 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
      1. 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
      2. 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
