Trenchless Horizontal directional HDD machine underground pipe laying under DL220

Main component configuration
DL220 horizontal directional drilling machine is a horizontal directional drilling device for one machine.
There are chassis, power head, drill stand, power station, vice, operating platform, automatic lever mechanism,Automatic anchoring device, hydraulic system, electrical system and other components

1,Chassis

The chassis mainly consists of main frame and left and right walking device. The rear end of the frame is provided with a hydraulic support leg,The traveling reducer adopts the built-in planetary reducer (including motor), which has large output torque and structure compact. It adopts the handle to control the caterpillar walking, the transition loading and the machine adjustment are convenient and safe.

2,Power station unit
The system consists of a diesel engine, a hydraulic pump, a slurry pump assembly, an overflow valve, and a hydraulic oil tank,The diesel tank, the valve block assembly, the accumulator assembly and so on.
The power station is powered by a diesel engine and the hydraulic pump serves as a hydraulic system
The supply of high pressure oil is the core part of the rig. The engine uses a Cummings engine with a total power of 110kW.

3,Push-pull device
The push-pull device provides feeding force or back force to the power head through an oil cylinder and a chain mechanism, High strength, reliable and stable operation.

Jiangsu Dilong Heavy Machinery Co., Ltd., as a member of International Society for Trenchless Technology (ISTT) and China Society for Trenchless Technology (CSTT), started the trenchless R&D since 1998. She is one of the earliest specialized private companies in no-dig technology development and construction in China. The company has our own engineering subsidiary. All types of products are applied to our own projects first, then the R & D center shall follow the feedback from job site and get improvement accordingly, finally we sell the product to other customers.

Our machine has already been sold to India, Russia, Indonesia, Vietnam, Singapore, Australia and other countries of the world. We shall maintain our commitment of quality product, timely technical support and consistent service as always, and your order shall be a new start for our long term cooperation.
