QY50B Truck Crane
 
QY50B Truck Crane adopts   self-made XZ50 special chassis, drive type 8×4.
 
Powerful Styre WD615.67A   engine conforms to emission standard of EuroⅡ.
 
5-section telescopic boom has   all-round hexagon boom profile or oviform boom profile.. Boom telescoping system   is double cylinders plus two-row of wire ropes, which? maximizes load lifting   capacity.
 
2-section folding jib with three kinds of offset angle and an   additional single top enlarge working range.
 
Double cylinders for elevating   have good stability.
 
Double H-shaped outriggers with additional front 5th   outrigger realize 360o full swing lifting operation.
 
Two independent winches   with variable displacement motor supply oil by single pump or double pumps to   obtain low speed with heavy load or high speed with light load at high work   efficiency.
 
Swing system with free-sliding function realize lifted load   automatically sliding to position.
 
Safe and reliable automatic load moment   limiter and hoist limit switch conform to China state compulsory   standards.
 
Operator’s cab, with adjustable seat and equipped with indicator   and pressure gauge etc, is convenient for operation. Air conditioner and heater   are for option.
 
Driver’s cab equipped with damping adjustable seat and   adjustable steering wheel is convenient for driving operation.
 
QY50B plateau   type, available for option of customers in highland area, is suitable for   operation in special working environment of heavy wind and sand, lower   temperature, rare air, and etc.
