P-62M / P-62L PNEUMATIC SUPPORT LEG

P-62M / P-62L PNEUMATIC SUPPORT LEG Pneumatic support leg P-62M / P-62L is used to increase performance and improve the comfort of working with a WUP-22 drilling machine. The support is intended to support the drilling machine during operation and to exert uniform pressure on the drill. The articulated connection of the pneumatic support to the WUP-22 drilling machine makes it possible to drill lateral and inclined holes. The support is equipped with a regulation valve which makes it possible to smoothly adjust the pressure force and the slide out speed, providing a firm working grip at the same time. The support is equipped with a quick release valve for reasons of work safety. The purpose of this valve is to withdraw the mining device immediately, interrupting the drill pressure.

WUP-22 PNEUMATIC PERCUSSIVE DRILLING MACHINE The WUP-22 pneumatic percussive drilling machine is designed for drilling blast holes in medium hard coal and rocks at air pressure of 0,4 MPa. Bore dust removal can be affected by flushing or scavening. To increase speed of penetration in horizontal or inclined drilling WUP-22 is adopted to work with an airleg of P-62M. The purpose of the airleg is supporting the drill during operation providing uniform pressure and relieving arduousness of men work. Pneumatic drilling machines WUP-22 require lubrication by compressed air from e.g. a duct lubricator. For WUP-22 we may apply the tools for hammer drilling: (monolithic) or rods and bits.
