XCMG QY70K-I China 70t crane arm truck with hydraulic system.
XCMG
QY70K-I truck crane bring customers new advantages. 6 specialized techniques,
load moment limit with color LCD make the machine outstanding in the market.
Exclusive telescoping technology prevents occurrence of core pipe bending, oil
cylinder bending and boom breaking caused by mis-operation, and therefore
operation safety is improved.
Advantages and highlights:
1.
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 condition.
2.
Hydraulic heat radiation system with superpower, permissible ambient
temperature exceeds 55℃
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 55℃,
which meets the requirements for high temperature operation.
3.
High-temperature resistant and ageing resistant wiring harness, service life
covers product lifecycle
The
protecting ply of wiring harness is produced according to QC/T29106-2004
Technical Conditions of Automobile Low-voltage Wiring Harness, heat-resistant
temperature is increased to 105℃, corrugated
pipes are added for protection, protection class of plug-ins is IP67. The
service life in high temperature operation exceeds 15 years.
4.
High-temperature resistant sealing elements, working efficiency is improved by
10%
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%.
