NGZ-31 Inner-combustion rail drillingmachine type internal combustion
operation between drilling machine is suitable for places where no power supply
shortages of high-power machine,
It is compact structure and lightest weight in Chinese market ,self locking
function clamp device ,correct borehole positioning and high drilling precision,
the machine USES the internal combustion engine as the power source, small
volume, simple operation, convenient maintenance,is about 75 kg/m, 60 kg/m,
50 kg/m, 43 kg/m rails to the ideal of the drilling machine.
The Internal combustion rail drilling machine fit the hollow drilling bit
and also twist bit (diameter≤13.5).
It has auto cooling water supply function. It’s an indispensable equipment
in railway maintenance.
This drilling machine is suitable for the maintenance and engineering
department of rail joint hole drilling, and the basic track of switch can also
be applied to the communication and engineering department of the guide rail
connection plug hole drilling, works departments using dia 31 tubular rilling,
electricity sector adopts special twist drill.
