Series 900 Scissor Bolters

Series 900 Scissor Bolter in an undergroung mine.

The original MacLean ground support paradigm shift.

The MacLean Advantage:

The MacLean Series 900 Bolters, the 928 (eight foot-wide deck) and the 946 (seven foot-wide deck) provide a complete ground support system for underground hard rock mines. The benefits of safety, productivity, versatility and quality of installation combine to provide the ideal tool for the mine development cycle and rehabilitation operations.

Benefits:
  • All operations carried out from beneath supported ground
  • Physical effort and fatigue are minimized compared to traditional rock bolting methods
  • The scissor bolter is designed for single person operation
  • Transverse feed enables drilling and bolting of a complete ring from a single set up
  • Single pass drilling allows for rapid installation of bolts
  • Versatility

Features:
  • Self-propelled, high speed four wheel drive articulated carrier
  • Electric hydraulic control system with remote drive capability on-deck
  • Hydraulic positioning, rock drilling/bolting systems
  • Operating protocol prevents exposure to loose rock hazards
  • Multiple types of bolts can be installed (resin or cemented grout rebar, Split Set® and Swellex® bolts, mechanical anchor, friction bolts)
  • Long hole drilling capability
  • Proven heavy duty scissor lift mechanism
  • High capacity storage for bolting supplies
  • 2000 lbs (900 kg) deck payload capacity
  • Forward shifting hydraulic deck

Applications:
  • Installation of screen or wire mesh
  • Long hole drilling for test holes or cable bolting
  • Rock bolt installation from invert to invert
  • Maximum back height of 6.57m (21.5ft) that can be reached by the stinger
  • Optimum back coverage of 6m (20ft)
  • Optimum wall coverage of 5m (16.5ft)  wide heading from single setup
  • 1.32m transverse feed travel
