The features of QY70K:
1,The concept of making "safe, environmental,
reliable and advanced" products is implemented during
designing and manufacturing processes.
2,Gross 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.
3,Excellent 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.
4,Electro-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.
5,Oval 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.
6,High 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.
7,Spacious and bright cabs for driver and
operator, equipped with heater and air conditioner, comfortable
for operation.
8,Powerful environmental chassis engine contributes
to excellent maneuverability.
