INTRODUCTION

AXERA D05 126-126XL is intended for use in mining, preparation work and tunnelling. It is an independently operating hydraulic rig that drills vertical, inclined and horizontal holes. Jumbo drills are used in mining, for making drills in all direction.The tamrock Axera D05-126 is a single boom electro-hydraulic jumbo for mining development in cross section up to 38 m2.

The robust universal boom have a large optimum shaped coverage, 360˚ rotation and full automatic parallelism for fast and easy face drilling. The boom can also be used for cross-cutting and bolt-hole drilling.The jumbo layout is designed for good visibility and balance, this and the powerful four-wheel-drive articulated carrier ensure fast and safe manoeuvering in narrow drifts.The high performance drilling system allows high drilling performance with good drill steel economy and high machine reliability.The operator environment and added automatic functions allow the operator to concentrate on safe, fast and accurate drilling.All the service points are well protected but easy to access.

DESCRIPTION:

The X-Y coordinated boom movements together with 360° actuator roll-over make the use of the boom simple and logical. Accurate automatic parallel holding both in vertical and horizontal plane improves the drilling performance and accuracy.

Large dimensioned rectangular profile, adjustable and sealed boom extension wear-pieces, large diameter bearings, sealed main joints, expanding pins in cylinder joints and use of super strong cast pieces in most stressed areas are some of the features that are included to the boom design for improve reliability.
