Jumbo drill

ZJ21

  • Aisle navigation Inside 3 m respective of feed length Inside 10 ft. respective of feed length
  • Height with canopy in drill/tram position 2.8 m 7 ft. 3 in
  • Width overall 1.7 m 5 ft. 6 in 

Exceptional flexibility and innovation in a common platform

Designed for flexibility and productivity, the ZJ21 is a jumbo drill on a first-ever common-carrier platform. The controls and boom let you convert your jumbo to a bolter, or vice versa. The ZJ21 also offers excellent useable coverage in a small jumbo platform.

  • Usable face coverage up to 66 m2 for getting the most from your application use cases
  • Engineered for higher uptime*
  • Improved operator adoption with simplified training on an easy-to-use, intuitive platform
  • *Higher uptime based on factors that include optimizing drifter and feed service intervals, ground level-maintenance and a boom geometry that limits damage to the front-end

Features and benefits

Common control system

Hydraulic pilot control system with universal drilling and bolting layout. Intuitive, common controls offer advantages in operator adoption, training and performance, as well as maintenance benefits.

Drifters with improved consumable life

Proven energy recuperation, hydraulic dampening, and progressive blow energy technologies help you to get the most from drilling. Drifter model options include Komatsu JZD10, JZD12 and JZD21, manufactured by Montabert.

Innovative boom geometry

Boom geometry prevents carrier interaction with the feed for added protection and less repair downtime. The ZJ21 shares the bolter boom lift geometry for excellent coverage (up to 66 m2) and allows a drill steel of up to 16 feet to be used inside the 3 x 3 m tunnel dimensions.

Telescopic and fixed drilling feeds

Lightweight, durable and cost-effective drilling feed delivers superior drill performance and reduced daily maintenance.

ROPS/FOPS-certified operator enclosure

Designed with zero-harm, ergonomics and comfort in mind. Standard hydraulic height-adjustable canopy. Enclosed cabin option with climate control available.

Common carrier design

The 100% design commonality from rear skirt to outer boom structure allows you to convert from jumbo to bolter. This innovation provides your operation with versatility while simplifying maintenance and training.

Application flexibility

Outstanding coverage in a small platform. Unique front-end geometry enables operators to reach lifters and perimeter holes easily, and drill more comfortably on various grades. The ZJ21 can even back up a two-boom jumbo in larger development headings.

Productive boom design

Superior aisle navigation in a 3 x 3 m heading (with 16-foot drill steel option), boosting output by pulling longer rounds in small headings.

Reliable, proven powertrain

Powered by a dependable diesel drive Dana T12000 Series with integrated torque converter and three forward/reverse speed options. Battery electric power model available in 2021.
