QY80K Truck Crane
◆QY80K is designed as 5-axle crane carrier with single engine,and the chassis has strong pass-ability.The engine is electronic-controlled injection engine with two operation control modes,environmental protection and high efficient.The oviform boom profile contributes prominent lifting performance for half and fully extended boom section.The combination of fixex counterweight and self-assembled counterweight and 2-section outrigger increase the crane overall lifting performance.The whole machine still holds the K series crane features, compact arrangement for each part, reasonable layout, good-looking appearance and ergonomically design.
◆The third generation of improved type operator's cab and driver's cab, interior space is more reasonable,streamlined appearance and unified style,and with our exclusive oviform boom profile.(three-color lamp is for option)
◆Various mechanism and control system are accurate to every detail.
◆The 5-axle crane carrier has excellent passability.
◆The smart and highly suspended arc type counterweight.
◆The hydraulic system is constant output variable displacement system,high work efficient and energy saving.
◆Centralized lubrication system.
◆The electronic-controlled injection engine with two operation modes,315KW output crane travel drive and only 180 KW output for crane lifting operation.
◆The overall sense is stronger,and the overall quality is superior.
◆The counterweight is self-assembly and with 3 type of combination.
◆The ergonomically and considerate design,beautiful shape and with good soundproff effect.
