QY50K (CE) Truck crane

Self-propelled chassis. The crane reaches workplace in short time, irrespective of roads condition.
All wheels of two front axles are turning, power steering system has emergency circuit. Rear axles differential with blocking and blocking between axles.
Extending outriggers with auto-levelling system.
Fully revolving body, with slewing bearing
Hydraulic drive with safety valves ensures wide range of adjustment of devices working speed and possibility of making many actions simultaneously
Main telescoping boom, with 5 sections (40m) with variable length. Hydraulic synchronized extending of boom’s sections enables moving the load in every direction of the space.
Folding jib (8,5-15m), mounted on main boom enlarges working range of the crane.

Crane Safety Load Moment Indicator using various sensing devices monitors crane's work functions and provide the operator with a continuous reading of the crane's capacity. The LMI provides the operator with information regarding the length and angle of the boom, tip height, working radius, rated load and the total calculated weight being lifted by the crane. If no permitted conditions are approached, the Load Moment Indicator will warn the operator by sounding an audible alarm, lighting a warning light and locking out those functions that may aggravate the crane's condition.
