Compare item

Pneumatic drill

YYTZ25-5 hydraulic rock drill unit

Construct preparation

(1)pneumatic drill (contain drill rig)tube and wire(wind water hydraulic oil) miscellaneous, waste a lot of time before and after work. (2)general preparation time need an hour

1)adopt integer design,frame compact,simultaneity the machine mates with track or wheels move conveniently, come under for the hole’s length and depth impact smaller. 2)Need about 20 minutes to arranged

Labor sanitation monitoring

Working face with more water fog,visibility low,between the working face 4-5 m can’t see anything.Noise high,between the working face 6-7 m can’t talking

  1. working face clean,can’t see any fog and dust,noise is low than pneumatic drill (2)after testing,the result as follow: Dust:0.26mg/m³
  2. Noise:instantaneous A voice level(LP)88.2~90.1dB(A)
