Product Overview

Description

 KDP-20 horizontal directional drilling machine

The KDP-20 is a full hydraulic Horizontal Directional Drilling Rig self-propelled with rubber crawler belts, integrated with power station and main power. It is convenient for moving and powerful of flexibility. Equipped with Cummins diesel engine, the rig is powerful with stable property. Adopting double-motor driven to the power head, the rotation will be steady with large torque. The power head equips with self-float shackle device to reduce the wearing of screw thread of the drilling rod, and then the operation will be easy and stable. All hydraulic hoses are covered into the protecting jacket to increase the service life. Convenient angle-adjusting cylinder, flexible adjusting of incidence drilling angle, adopting motor-chain machanism to the feeding pull-back, the same thrust power and pulling capacity, effect the direction controlling at a long distance easily. Double-holder makes the rod loading and unloading efficient. The KDP-20 rig is with the advantages of full hydraulic driven, centralization control, easy and nimble to operate.
