Specifications:
J151 E single boom jumbo is specifically designed for development and production drilling in headings from 10 ft. by 10 ft. (3m by 3m) up to 24 ft. wide by 20.5 ft. high (6.3 m high by 7.6m wide) in one carrier set up.

Diesel tramming with electric hydraulic drilling enables cost effective drilling with the flexibility of fast heading to heading moves. The compact size and articulated design allow the jumbo to tram and setup in tight headings, circular ramps or crosscuts.

Operator is comfortable in a fully enclosed, sound suppressed, MSHA certified cab. Cab has excellent visibility for both drilling and tramming. Cab can include an optional air conditioning/heating system that uses HEPA filtration for both the introduced make up air and the recirculated interior air.

All operator controls for drilling and tramming are either pilot operated or 24 V DC solenoid controlled, minimizing the noise and heat that is generated within the cab. Joystick operated drill feed and boom controls simplify and improve the hole to hole positioning. All operator controls are conveniently located for comfortable operation from the standard "Captains" style seat. The seat can be rotated to give the operator a clear forward and aft view.
