YUCHAI Mini Excavator

Founded in 1989, Yuchai Heavy Industry is the earliest excavator company in China to produce mini excavators and sell them to the world. It is the largest production and export base of small excavators in China and a national high-tech enterprise.

More than 30 years of innovation and development, providing customers with high quality assurance!

YANMAR engine

YANMAR engine

Engine power reserve increased by 30%

Power/Speed 14.5/2400 (kW/ RPM)

Engine with muffler. Aluminum, oil-dispersed, water-dispersed parallel radiator.

Load sensitive system

Load sensitive system

The movement is light, swift, powerful, coordinated and efficient.

The load sensitive control system has lower power consumption and higher efficiency than conventional hydraulic system.

High efficiency and low power consumption save fuel and reduce heat of hydraulic system.

 Telescopic chassis

Telescopic chassis

The chassis can narrow to 1080mm at the narrowest, extend to 1400mm, and can pass through narrow passages.

Interchangeable track

Interchangeable track

Rubber tracks are standard version. Rubber tracks and steel tracks can be Interchanged without support wheel.

Yuchai U18 mini excavator

Full Pilot Control

More comfortable driving experience and smoother movement

The Boom Can Be Deflected Left and Right

Maximum left deflection angle of boom is 70°.

Maximum right deflection angle of boom is 60°.

It improves the flexibility of the excavator bucket, reduces the working space, so that the bucket can rotate when the machine body and boom remain stationary.


Two columns canopy → four columns cabin. The cab is interchangeable.

Various Attachments

More than ten types of attachments

Hydraulic hammers, buckets, quick change devices, wood grabbers, simple grab pliers clearing bucket, clamshell bucket, drilling tool, lawn mower, etc.

More than 40 key working conditions are applied, with a wide range of working conditions.
