Product Description

New Model 70ton Hydraulic System Truck Crane qy70K

QY70K is the most popular model of China 70 ton truck crane, With the features of maturity and reliability of the old model.

Advantages and highlights:

1. The layout mode of oil port of radiator is optimized, heat radiating area of core is increased by 50%, radiation power of hydraulic oil radiator is improved from 10kW to 18kW, permissible ambient temperature exceeds 55ºC, which meets the requirements for high temperature operation.

2. The protecting ply of wiring harness is produced according to Technical Conditions of Automobile Low-voltage Wiring Harness, heat-resistant temperature is increased to 105ºC, corrugated pipes are added for protection, protection class of plug-ins is IP67. The service life in high temperature operation exceeds 15 years.

3. The seals of key hydraulic components such hydraulic pump, hydraulic motor, extension cylinder, jack cylinder, steering boosting cylinder, elevating cylinder and telescoping cylinder are upgraded to high temperature resistant silicon rubber lip seal, working efficiency is improved by 10%.

4. High-power air-conditioner meets the requirements of T3 working condition High-power air-conditioners are equipped in driver' s cab and operator' s cab, heat transferring area of condenser is increased by 75%, displacement of compressor is increased by 20%, refrigeration effect is improved by above 25% relative to regular products, which meets the requirements of T3 working
