Mini-excavator, Compact Excavator, Mini-backhoe

The compact crawler excavators are scaled-down versions of the large excavators you often see on many construction sites. The mini-excavator is intended for underground construction and mineral exploration projects. This construction equipment is noted for its small size but its electric hydraulic system is powerful yet extremely efficient and quiet. The machine can be used along with the vertical shaft drill rig to achieve a faster drilling speed and minimizing construction times. You will often find these excavators in vertical shafts, slope mines (with gradients less than 14°) and drift mines, for rock collecting, mining waste removal and digging through frozen earth.

Configurations of Mini-Excavator
Slewing Platform

In the slewing platform of compact crawler excavator, a welded structure provides high rigidness. The bottom of the platform is connected with the base plate through a slewing bearing. In the middle, there is a robotic arm and slewing reducer, which with the slewing bearing composes a slewing system. On the right of the slewing platform, hydraulic oil tank and main valve are installed. On the left is operating cap, equipped with a comfortable seat, a protective roof and pilot valves.

Walking System
The whole walking system consists of crawlers, base plate, walking drive device and crawler stretching device. That’s why the excavator shows a good capacity in climbing slope and turning sharply, as well as enjoys low ground pressure and stable walking. The installed two crawlers are independently driven by two driving devices, able to freely walk, swerve, rotate and more.

Hydraulic System
Main parts include main oil pump, gear pump, hydraulic motor, hydraulic cylinder, main valve, pilot valve, oil filter, cooler and oil tank.

Dynamic System
The explosion-proof motor distributes electrical power of 37 KW to each device of this excavator and ensures a normal and highly efficient running.

Electrical System
The compact crawler excavator is outfitted with a vacuum electromagnetic starter, which is most often used to control and protect the main motor. Not only that, the excavator also makes use of an integrated protective device, which prevents the lighting system and bell from short circuits and electric leakage.
