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.
