XCMG Truck Crane (QY70K)

XCMG QY70K Hydraulic mobile crane is one of the most popular crane in all the xcmg cranes.The features ofXCMGQY70K Hydraulic mobile craneare:1The concept of making safe, environmental, reliable and advanced products is implemented during designing and manufacturing processes for xcmg crane qy70k.2 XCMG CRANEGross vehicle weight is reduced and reliability is improved greatly due to adoption of components made by established manufacturers worldwide, as well as first class steel plates and key hydraulic parts.3XCMG CRANEExcellent lifting performance and wide working areas due to variety of counterweight combination, outrigger positions (fully extended and half extended), single top. Its main lifting performance ranks first in domestic similar products.4Electro-hydraulic proportional control system and hydraulic system equipped with advanced electro hydraulic proportional valves, slewing buffer valves and electric variable motor contribute to improvements on smooth operation and inching control.5Oval cross-section boom has features of strong anti-torsion and reasonable transfer of tension. New materials such as WELDOX 960 super-high tension steel, glass fiber reinforce plastic and aluminum alloy not only meets high performance requirements, but also reduces gross vehicle weight.6High working efficiency is achieved by adoption of double variable main hoist system contributing to low speed with heavy load, high speed with light load and energy saving, as well as high elevating and telescoping speed.7Spacious and bright cabs for driver and operator, equipped with heater and air conditioner, comfortable for operation.8Powerful environmental chassis engine contributes to excellent maneuverability.
