Construction Machinery CDM6485H features:

This model has many optional working devices, and has strong travelling driving force. The ground clearance is high. It adopts to mining and other serious conditions. The undercarriage can be disassembled, so it’s easy to be transported.
This model is widely applied in mines and earthwork sites such as mining, road construction, railway construction and urban construction.

Strong power system
Adopt the QSM11 series engine with low noise, low emission and strong power that supports the work at high altitudes and meets Phase III waste gas emission standards of Europe and America.

Advanced hydraulic system
Adopt the double-pump double-loop negative flow control system that follows technical and intelligent electric proportional control and allows the engine and hydraulic power to be always consistent, thereby improving power utilization and fuel economy.

Excellent computer monitoring system
Set three power control modes to meet different load requirements.
Adopt the integrated electro-mechanical hydraulic technology to realize intelligent control, this technology can perform auto-diagnosis and auto-alarm display to the fault and it can provide functions of automatic idle speed, automatic engine overheating protection, auto-prompt of maintenance information and history fault log.
The multi-function monitor can fully monitor engine speed, coolant temperature, engine oil pressure and fuel level and so on.
Automatic sound warning for travel.

Multi-function comfortable luxury cab environment
The spacious and multi-function cab designed according to ergonomics enhances comfort for operator.
The luxury suspension seat can be regulated to provide optimal comfort for driver.
The mounting seat of cab adopts silicone oil & rubber material, it can both reduce the vibration and noise in the cab and greatly reduce the driver's fatigue, tremendously enhancing work efficiency.
The high-power air-conditioner and multi-hole circulating system enhance the refrigeration and heating capacity, to ensure comfortable temperature in the cab.
The cab has protective railings, so the operator is safer and more comfortable.

Convenient maintenance system
Three side doors can be opened, so that each maintenance point can be accessible when routine inspection and maintenance are performed.
• The label of maintenance point is clear and simple, convenient for operation.
• Electrical components are all arranged in the cab and the electrical control box for easy maintenance.
Walkways are increased on both sides of the platform, avoiding the trouble from ground maintenance and making maintenance easier.
The engine hood is opened a small door for the part of the engine needing maintenance, so that maintenance work becomes very convenient.
