Product Description
HT21 series of mini excavators inherited Hengte's innovative design concept with the design of 450 ° no tail swing in the structure, full-power variable pump control system, compact structure, flexible operation, and easy maintenance. It is the ideal equipment to replace manual constantly, freeing up labor in agriculture, forestry, water conservancy, and construction industry in the future.HT21 mini excavator is the result of in-depth market research, taking the advantages of domestic and foreign products. It is a high configuration, high cost-effective product with distinct advantage compared with other Chinese manufactures. It's finished after more than two months.
1,The whole appearance is designed with 450 ° no tail swing streamlined. The front of HT21 is self-designed with movable arm side shifter; so that the machine can swing around 45 ° and work in the wall corner and other narrow zones.The overall outline use non-tail swing design. It can operation easily and expand the scope of application of the machine when the upper body is rotated in the narrow area. The no-tail design has obvious advantages and rotation safety than other domestic products, has obvious advantages.
2,The engine is Laidong LL380B with maintenance service outlets all over the country. It is low- fuel consumption and low noise.
3, HT21 is Japan KYB piston pump so that the big arm, small arm and rotation own their independent hydraulic system to achieve fast, smooth and powerful operation. There is a significant performance advantage compared with the gear pump.
.
4,The main valve is Parker with highly efficient and excellent operating performance, with broken pipeline and a control device. It can work immediately after install a breaking hammer.
5,The swing motor is 2.5K Eaton with reliable quality, large displacement, high torque and conditions adaptability.
6, The performance of import Eaton walking device is more stable and the quality is more reliable.
7,The guide handle is short handle control valve, which makes on and off more easily without affecting performance to prevent misuse and increase security.
8,The special armrest is high-grade and left is liftable with small swing angle, which is beautiful and easy to get on or off. The right box handle is rotatable and liftable with user-friendly design.
9,The integrated dashboards can display temperature, speed, oil pressure, work time and other parameters.
10,All pipelines are built in work equipments to prevent damage and improve job security. The boom cylinder is installed in the top to avoid bruising the cylinder when working.
11,They are all Q345 steel welding including chassis, shelves and important load-bearing parts of work equipment to assure the safety and reliable. Rubber track can reduce the vibration without damage.
12,The hydraulic hose is made by a famous domestic brand Guangzhou Tianhe with withstand voltage 35Mpa. The connectors are made by Suqiangge to prevent oil spills.
13, Convenient Maintenance
(1) It is convenience to add antifreeze and check radiator when the left hood can be opened.
(2) Horizontal open rear hood is convenience to check the engine.
