Product Description:

1,Hydraulic system provide perfect power and accurate control to ensure continuous digging operation.

Main components, such as pump, valve, are manufactured by international top brand enterprises.

There is an open hydraulic system with Tri pump & Tri circuits, controlled by load sensing system and limit power to ensure higher efficiency and productivity at the lower est hydraulic loss. Reasonable power distribution and double pumps with crossover power control system can reduce circulation time under multiaction operation and promote productivity.

Swing secondary pressure control for better starting and braking pressure so as to ensure fast and stable swing operation.

Hydraulic hose, connection: world famous brand with excellent performance ensure better reliability for operation in mine.

High efficiency features:

Starting with zero displacement with better starting load and starting performance

Technique with minimum flow control at neutral position for best energy saving and economical efficiency

Technique with pressure cut-off to provide better system protection

Control of constant power of single pump, limited power of three pumps for reasonable distribution of engine power

Confluence of three pumps for combined movements and increasing of operating efficiency

Logic valve control for automatic straight traveling, automatic release of swing brake

Confluence of two pumps for increasing operating efficiency

2,Power system(Unique power-driven technology in China)

Electromotor

Clean energy: zero-displacement, environmental friendly

Low cost: compare to diesel engine, the electromotor is more economical

Maintenance free: lower operating cost and easy maintenance

Separate hyd-oil cooler with better cooling effect and easy maintenance

3,Welding&casting structure for working attachment

Adopt international top brand cylinder seal for better sealing property

Working attachment pins are made of special wearresistant alloy, hardening and chroming treated for getting high strength and long circle life

4,Automatic central ludricating sestem

Top brand automatic central lubrication at setting time interval, for specified quantity and at all lubrication points. which results in saving of manual daily maintenance, reduced manpower and increased productivity

5,Classified esign & manufacture based on working condition

Special design & manufacturing of bucket, undercarriage, working attachment and other structure parts based on different working condition; customizing design on power unit, hydraulic system, oil products and electrical system to make our products suitable for all kinds of adverse circumstance

Working attachments such as breaker, cultivators, quick-change connector can be equipped to meet different working requirements

Hydraulic systems are pretty well sealed and have the advantage of being able to be designed to move and manipulate very heavy loads. the space shuttle is loaded with quite a few hydraulic systems.
Q:Where can i find a diagram and explanation of a hydraulic circuit of an excavator?
Search online for the operator's manual for the specific brand/model number of excavator you are looking at. You may even be able to download a free copy from the manufacturers website. Most hydraulic circuits consist of a pump and motor to force fluid through the system, a reservoir to hold the hydraulic fluid, valves to control the flow through the system, cylinders or other devices that transfer energy into a usable force for doing work, maybe a filter. There will be other components but those are the most basic fundamentals of a hydraulic circuit. Good luck and have fun!
Q:Disney show/movie about a dinosaur in a swamp that's actually an excavator?
Could be Frog Dreaming from 1986.
