Product Description
Key Features
Easy to maintenance,repair,disassembly,installation and movement.
The power unit is mounted on a mounted frame,which is easy to move,and can leave a distance to the main body when it is working. The power unit has a high power electric motor,double hydraulic pumps(the primary one to serve the rotation unit while the auxiliary one to serve the feed oil cylinder),hydraulic box,filter,handle pump,oil condenser,electric control box.
Fast drilling speed can drill holes from any angle in work tunnel by column,
The main body consists of feed frame,rotation unit,rod holder,column,cylinder.facilitate to assemble or tear down.It can drill holes from 0°~360°in work tunnel by column.
Oil pump drive the motor to rotate,hydraulic cylinder working without turret.
The control is simple and easy by operating the bar;the workers only need to put on or pull the rod;and all the work could be done.It can auto-feeding and the feeding force and work speed are easy to control.The operation actions of chuck and rod holder are synchronized.The operator can easy to fix run load the rod without the spanner.The instrument boards show feed pressure,system pressure and flushing water pressure values,which increase the work efficiency greatly.
