JUMBO 250

GENERAL FEATURES

 

Jumbo  250  is  suitable for vertical, horizontal and slant  drilling using a down-the-hole hammer and offering a variety  of  drilling  options adaptable to different working surfaces. We can proudly certify  that Jumbo 250 can resolve  any  perforating  task with  any type of material, be it marble or granite, without the need  for a cooling system  or  difficult  maintenance.  The machine is mounted on a support and transportation trolley that allows
easy manoeuvring within a quarry. Perforation can be performed  at a maximum drilling depth of 30 m. When the column  is  mounted on  a  trolley  its  positioning is controlled by a hydraulic cylinder, allowing to place the column  in  any position from 0° to 90°.  The column  can  be easily detached  from the trolley for  horizontal or vertical drilling.
The  consumption  of compressed air is reduced  to  a minimum  as it is only used to operate the down-the-hole hammer, while the rotary head, the drilling feed and the positioning of the  column are hydraulic. Jumbo 250 is individually  assembled according to specific requirements of a client.The standard  machine is equipped with 1 m conical drilling rods, a 2" to 8" down-the-hole hammer and 70 to 250 mm diameter drill bits.
