MACLEAN ENGINEERING: EQUIPPED TO SUPPORT GLOBAL MINING & TUNNELLING OPERATIONS
MacLean Engineering enhances its Ground Support product offerings with the addition of a new Small Section Bolter and line of Shotcrete Vehicles.
MacLean Engineering has long been known in the global mining industry as a leader in the Ground Support field of mechanical rock bolting technology. Since its beginnings in 1973, MacLean has produced over 280 Scissor Bolters. Expanding on its expertise in Ground Support, MacLean Engineering introduces a new Small Section Bolter (the MacLean MEM-SSB Small Section Bolter) and a line of Shotcrete Vehicles, which includes the SS-3 Shotcrete Sprayer and the TM-3 Transmixer.
“MacLean’s mission is to satisfy our customers’ needs through the design, manufacture and support of the safest and highest quality mobile equipment solutions possible for the underground hard-rock mining industry. With the introduction of the Small Section Bolter, Shotcrete Sprayer and Transmixer, we are now able to offer our customers a complete solution to Ground Support,” says Alicia Woods, Sales Director at MacLean Engineering.
The MacLean MEM-SSB Small Section Bolter is the first of its kind in the mining industry. Its unique lift-arm design equips this platform-based bolter with superior leveling capabilities offering increased stabilization and operator safety. The bolting mast remains on the platform, as on the standard-size Series 900 Scissor Bolter, giving the operator exceptional screen handling and scaling capabilities. This unique lift-arm design and platform make the MEM-SSB a much more productive unit as compared to other boom-based bolters. Designed for a minimum working heading of 10’ x 10’ (3m x 3m) makes the MEM-SSB ideal for mines with smaller drift openings and for those wanting to reduce the amount of waste they mine.

Complementing MacLean’s Ground Support rock bolting equipment is its new line of Shotcrete vehicles. Advancements in shotcrete equipment technology, logistics and materials make shotcrete an ever-growing trend in mining today. The TM-3 Transmixer and SS-3 Shotcrete Sprayer allow mines to develop underground areas and tunneling projects quickly and safely using highly flexible and durable ground support materials.
The MacLean SS-3 Shotcrete Sprayer optimizes the latest developments in wet shotcrete materials, additives and spraying processes. The unit accommodates shotcrete composite up to and including 5/8” aggregates, reinforcing fibers and accelerator curing agents and is capable of a spray rate of up to 20 cubic yards per hour (15 m3/hr). The first MacLean SS-3 was delivered to Canada’s largest operating Gold mine, Agnico-Eagle’s LaRonde Mine in Quebec, this October. The SS-3 will join a fleet of MacLean equipment consisting of Boom Trucks, Secondary Breakers, a Scissor Lift and eleven Series 900 Scissor Bolters.
The MacLean TM-3 Transmixer is capable of a payload of up to 7.8 cubic yards (6.0 m3). When compared to what the market currently has to offer, this cuts most delivery trips in half, saving time and money. Standard features, like the low profile reverse tilt drum, make this hauler easily compatible with any spraying unit. J.S. Redpath Limited purchased the first Transmixers out of production; two units are now in operation at Barrick Gold Corporation’s Storm Mine in Nevada.

The expansion of its Ground Support equipment line-up was a natural progression for MacLean Engineering. MacLean has observed in their customers a desire to work in smaller headings and an increase in use of shotcrete, either alone or combined with traditional bolt and screen methods of ground support. The new Shotcrete vehicles and Small Section Bolter together with the proven “MacLean Bolter,” position MacLean Engineering as a leading supplier of comprehensive Ground Support.
