1. small volume, light weight, complete function and convenient transfer.
2. high technical performance. The design and manufacture technology of modern hydraulic excavator has been well developed in the small hydraulic excavator for road construction, and the mechatronics technology and industrial modeling technology have been widely used. New materials and new technologies such as engineering plastics are constantly used.
3. compact structure. It adopts full hydraulic transmission, and multi-channel distribution valve is lying in the platform. The cab can be turned over 30 °. The whole machine counterweight is set down, and the engine can be maintained and generally maintained by opening the engine hood, without removing the counterweight block.
4. it is applicable. The crawler of the walking mechanism adopts rubber track as its standard equipment, and steel track is optional. Some models are equipped with hydraulic lifting mechanism on the chassis, which can tilt the platform of small hydraulic excavator for road construction by 15 ° ~20 ° to make the excavator more suitable for slope operation. There are many kinds of working devices, and sometimes a machine can be equipped with several, more than ten or even dozens of operating devices. The working device can be left and right, and the largest one can be set 90 ° which is very beneficial for the construction in narrow and small sites and on both sides of the road. With bulldozer, it can be used for bulldozing and leveling. When digging, the soil plate can support the ground, and the better stability can be obtained.
5. it is simple and flexible. Because of the full hydraulic transmission, it is light to operate, including the foot control, and the control force of the control lever is not more than 40N.
