Gardner-Denver Universal Jumbo Twin Boom Drill Rig for drilling parallel holes


 

Versatility
 

The Gardner-Denver Jumbo is a multi-purpose machine, and is not restricted to only one function, such as drilling parallel holes. The Universal, as the name implies, drills burn cuts, V-cuts, cross cuts, stopes, rock-bolt holes, etc.
 

Ruggedness

The heavy-duty undercarriage features a one piece rigid structural frame, heavy-duty planetary axles, low pressure wide tires.
 

Maneuverability
 

A highly efficient power steering combined with short wheel base, reduces the turn radius to a minimum. Automotive type steering that allows the Jumbo to tram close to the wall, without fear of "locking side" as in case of articulated steering. The compactness, low profile and operator side seating feature permits the machine to negotiate headings as small as 10' (3.05 m) wide x 9' (2.7 m) high.

Highly mobile, highly flexible, the Universal Jumbo uses the building block design to give you the combination of components and options you want. And as the conditions and assignments change so can the Jumbo.

This basic drill carriage can be put to a number of mining tasks by assembling various combinations of engineered "building block" components.

JT144/DPT
 

Boom and Positioner Combination


Technical Parameters: 

1. JTI-DPT Boom and Positioner Combination is a roll-over-type Boom for full face coverage
2. 360º rollover capability; full-circle coverage pattern; eliminates blind spots
3. Rotation in both directions allows the hose harness to be kept clear from damage or twisting
4. Rollover reaches the lower toe holes at the bottom of the tunnel face
5. Completely enclosed rotation mechanism prevents debris from jamming the Boom
6. A wide RANGE of drilling components, feeds, and drills can be mounted on the Boom; choice of right or left hand mounting; vertical or horizontal bracket
7. Hydraulically operated, easily controlled; for swift and POSITIVE positioning all cylinders include checkvalves to LOCK the boom in set position in the event of power loss or hydraulic fluid leakage
8. Drill positioner can be REMOVED from the the boom; replacement by stock units reduces costly downtime and assists maintenance programs
9. Rigid construction; provides a RIGID mounting for feed and drill components; PRECISE drilling; reduces wear; mounts longer feeds and larger drills
10. Simple maintenance; all swivel joints are easily lubricated or REPLACEABLE; insure maximum SERVICE life of major components
11. Multiple Booms; several units can be combined on a single jumbo rig to provide a MAXIMUM coverage pattern.


The JTI 144 Boom and DPT Positioner used as a combination unit result inthese maximum overall equipment capacities.
