Product Description

(LG6220d) Lonking 22 Ton Excavator

Feasures
LG6220D with strong, powerful and high quality engine and advanced negative flow control hydraulic system to achieve the best power matching and minimum costand guarantee the optimum working efficiency.
Filtering System
The high efficiency dual element air filter ensures the quality of engine air intake. In addition, the air pre-filter can carry out the rough filtration over the air intake to enable the operation under the poor air quality working conditions and prolong the maintenance interval of the air filter. The oil-water separator and two-stage fuel filter will filtrate the fuel many times to ensure the quality of fuel fed to the engine.
Cooling System
The parallel radiator cooling makes cooling effect better and service easier.
Maintenance and Service
The easy maintenance of direct injection engine reduces the cost of maintenance. The global after service of engine enables the sharing of global resources. This will enhance the service efficiency, relieve the customers of worry about the service and ensure the attendance rate of excavator.
Functions
This machine allows the functions of straight travel, boom/armconfluence, boom/arm holding, swing priority, swinganti-reversing and regeneration ofarm cylinder. Each circuit without interference during composite action.Digging of arm and bucket as well as the lifting and swing of boom at the same time during operating, the operations of left and right motors are independent during traveling.
Auxiliary Hydraulic Valve
The main valve is provided with a set of standby valves to facilitate the installation of other accessories such as the breaking hammer.
