Piling Auger Drill Rigs

Product detail  Piling Auger Drill Rigs for Highway and Foundation         ZDD100a drilling equipment has simple structure, easy operation, low price, energy saving,and can also drill vertical and horizontal blast hole, especially it has low center of gravity and detachability is good, so movement and transportation are convenient.         ZDD100a electric drilling rig is the equipment that converts the electric energy and compressed air into mechanical energy to break rock. After electrify, the drilling tool is driven by the torque produced by cycloidal reducer through the intake seat. Compressed air are divided into two way after going through oil mist device and pneumatic valve: one way enters into the cavity of promoting cylinder, which produces an axial force drives the drilling tool to promote or elevate through the cylinder piston and guide rod; the other way enters into the impactor through the intake seat, so as to achieve impact drilling.  Advantages of Down the Hole Hammer Drill Rig  1. Powerful and reliable engine  2. Powerful feeding and rotating system  3. New drilling boom  4. High power drive motors  5. Safe and stable travelling system Photo of product
