Above on the page there are several PDF Manuals for YUCHAI Hydraulic Excavators, Spare Parts Catalogs.
Mini-excavator - a single-bucket hydraulic excavator with an operating weight of not more than 7.5 - 8 tons.
Machines of this type are designed for digging, extracting and moving soil, but due to their small size they can work in confined spaces and be transported on trucks and trailers without special training.
Mini excavators are used in construction, landscaping and other industries where a small amount of excavation is required.
The first mini-excavator prototypes were built in Japan in the late 1960s by Yanmar.
Serial production of machines was launched by the same company in 1971.
Kubota introduced its mini excavator in 1974.
In subsequent years, the production of mini-excavators was launched by almost all the leading manufacturers of large earthmoving equipment.
Structurally, mini-excavators are similar to full-size machines.
The basis of the excavator is a caterpillar or wheeled chassis, on which there is a turntable with an operator's seat, a power plant and working equipment.
Yuchai excavator equipment consists of an articulated-lever boom with a hydraulic drive; a bucket is used as the main working body.
However, in most cases, it is planned to replace the bucket with other working bodies - a grab, a hook, a hammer, etc.
Yuchai excavator operator's workplace can be open (closed with an awning) or located in a small cabin.
As a power unit, diesel engines with a capacity of 5 - 50 hp are usually used.
To ensure stability and clear the site, a low blade is mounted in front of the excavator chassis.
The wheel trailed mini-excavator has a similar design, but it has an open operator's station and is equipped with outriggers (supports).
