(1) Small size, light weight, complete functions, easy transfer.
(2) High technical performance. The design and manufacturing technology of modern hydraulic excavator has been well developed in small excavation, and electromechanical integration technology and industrial modeling technology have been widely used. Engineering plastics and other new materials, new processes are constantly used in small excavators.
(3) Compact structure. The small excavator adopts full hydraulic transmission, and the multi-channel distribution valve is lying in the platform. The cab can be turned over for 30 minutes °。 When the engine hood is opened, the engine can be maintained and repaired without removing the counterweight.
(4) It has strong applicability. The rubber track is used as the standard equipment of the walking mechanism, and the steel track is optional. The chassis of some models is equipped with a hydraulic lifting mechanism, which can tilt the small excavator 15 ~ 20 degrees above the platform °， The excavator is more suitable for working on the slope. There are many kinds of working devices. Sometimes a machine can be equipped with several, more than ten or even dozens of working devices. The working device can swing to the left and right, and the maximum can swing to the left and right by 90% °， This is very beneficial to the construction of small excavators in narrow sites and on both sides of roads. With a bulldozer, it can be used for bulldozing and leveling operation. When excavating, the bulldozing plate supports the ground, which can obtain better operation stability.
(5) The operation is simple and flexible. Due to the full hydraulic transmission, the operation is light, including walking foot control, and the control force of the control lever is not more than 40N.
