2.2ton Crawler Excavator
The crawler excavator is a compact excavator ,which matched LAIDONG tier III engine , the boom of excavator can swing to left or right , suitable for different director digging for your working , fitted famous brand main pump and valves , fitted international brand driving motor and slewing motor, hydraulic pilot servo operation system, with rubber track, with hydraulic broken pipeline system.the machine can changed track from rubber to steel and cabin from open to closed.ensure it can work in different working environments and conditions.
Compact, light and small turning radius, are its unique structural features; which makes it plays a biggest role in limited working sites.

What is a mini excavator?
A compact or mini excavator is a tracked or wheeled vehicle with an approximate operating weight from 0.7 to 8.5 tonnes. It generally includes a standard backfill blade and features independent boom swing.
Hydraulic Excavators are somewhat different from other construction equipment in that all movement and functions of the machine are accomplished through the transfer of hydraulic fluid. The compact excavator's work group and blade are activated by hydraulic fluid acting upon hydraulic cylinders. The excavator's slew (rotation) and travel functions are also activated by hydraulic fluid powering hydraulic motors.
Most compact hydraulic excavators have three distinct assemblies: house, undercarriage and workgroup.
In recent years, hydraulic excavator capabilities have expanded far beyond excavation tasks. With the advent of hydraulic powered attachments such as a tiltrotator, breaker, a grapple or an auger, the excavator is frequently used in many applications other than excavation and with the tiltrotator attachment, actually serves as an effective tool carrier. Many excavators feature quick coupler (quick-attach) mounting systems for simplified attachment mounting, dramatically increasing the machine's utilization on the jobsite.
