UTILITY VEHICLES Suspension system installed on DUX unit with totally enclosed, fully equipped cab DUX improvements After installation and intensive testing on DUX model TD-18 and DT-20N underground trucks, DUX has now made available its new operator suspension system on all haulage and utility equipment with a totally enclosed FOPS/ROPS cab or canopy. Able to withstand the rigours of harsh, underground mining conditions and Model DS3.8 Boom available for field installation on DUX DS Series scalers particularly well‐suited for applications requiring travel over longer distances at higher speeds; the system significantly softens impact loads and vibration levels experienced by the driver and co‐driver. DUX is also currently in the process of manufacturing this system so it can also be offered as a retrofit kit for field installation. For roof control underground, DUX can now replace an old scaling boom with a newly designed, lighter version available with rotary head and bracket for the installation of optional hydraulic hammer, scaling claw or rotary cutter for use on soft material such as limestone, salt or potash. The new DUX DS-3.8 provides a telescopic extension of 3.80 m (closed boom length: 5.23 m). It provides a maximum reach at 55° boom angle of 10.05 m. The weight of the boom assembly without pedestal is 3,040 kg. Battery power Battery power was the subject of one article last month. This is a field in which MacLean Engineering leads. At the PDAC conference in efforts across 2017 focussed on rolling out EV propulsion packages across the full range of the company’s product lines in both standard 2.4 m (8 ft) and smaller section 1.8 m (6 ft) carrier configurations. “A mobile fleet propulsion system that can significantly cut ventilation costs and at the same time reduce heat and improve air quality in the underground environment - this is the compelling business case for the new era of battery power in underground mining, one that we’re fully engaged in for our global customer base,” remarked company President Kevin MacLean at the time. The MacLean approach to EV propulsion for underground mining is built on giving customers access to best-in-class battery, electric motor, onboard charging (ie no additional charge station infrastructure required), and vehicle analytics technology, and then successfully integrating James are a scaler and grader. For road maintenance underground the grader can be supplied with or without ripper teeth to ensure the best way of road preparation. UNDERGROUND MINING EQUIPMENT WORLDWIDE With over 45 years of experience, DUX offers a full range of products designed to meet the needs of mining and tunnelling projects worldwide.

It is providing a battery powered fleet to Goldcorp’s Borden project in Chapleau, Ontario, expected to be the world’s first all- electric hard rock mine by the time it reaches production stage. The company’s R&D these components into mobile equipment by leveraging the company’s multi-discipline engineering expertise, hard rock mining knowledge, and custom manufacturing experience. In other words, you can't just understand the battery cycle, you need to understand the mining cycle it's going to be used in. This is how MacLean has developed battery power, engineered for life underground. PMP offers three battery-powered personnel vehicles that can be customised for other tasks. The Marmot is a four-wheel drive, 0.5 t unit featuring intuitive, easy-to-learn controls with a patented modular control system. With four- wheel independent suspension, it is capable of climbing 2.5 km vertical elevation at 20% grade. Crew cab and closed cab configurations are offered.
