One of Northern Ontario’s Five Best Places to Work

Industry leader grooms talent from within By NADINE ROBINSONFor Northern Ontario Business As Tasha Kingsley drove into work, she noticed the 10 international flags representing major customers at RDH Mining Equipment (RDH) were barely fluttering. She knew it was going to be another scorcher of a day in Alban. In their newly expanded 15,000-square-foot facility, Kingsley would be cool in the air-conditioned office, but it would be a different story for shop workers.Thankfully for those designing and fabricating the mining and underground mobile tunnelling equipment on site, 60 kilometres south of Sudbury at French River, the owner would soon arrive with frozen treats for everyone. “Four employees bought RDH from the previous owner, so they know what it’s like to work those hot summer days,” said Kingsley.“The owners truly care about employees and want to do what they can to make them comfortable.”In 2013, RDH made the list in the Annual PROFIT 500 Ranking of Canada’s Fastest-Growing Companies (by PROFIT Magazine). Established in 1984 with three employees, RDH has now grown to 56 employees.Popsicles aren’t the only advantage to working at RDH; fish fries are also common. “We’re a pretty social group,” said Kingsley, executive assistant to the COO. “Partially out of necessity, since we are quite isolated, but we’re now a big goofy family, and the company likes to celebrate accomplishments like the completion of a major order.”Since RDH become an industry leader by creating the first fully independent battery-operated underground mining equipmentin 2012, there have been a lot more fish fries.“Being an innovative industry leader is a source of pride for our employees,” said Kingsley.RDH believes in nurturing the close-knit atmosphere, with activities like golf tournaments, where employees, owners, andkey suppliers all vie for prizes, a trophy, and bragging rights.“There’s always a lot of joking, laughing, and fist-bumping… And of course we round out the day with a chicken...

Machinery you can feel good about….

In mining, many companies are having to go deeper underground in their search for more minerals. In order to meet the increasing demand for equipment suited to this environment, RDH Mining Equipment Ltd. has led the industry with the development of fully independent, battery electric underground mining equipment. In 2011, it introduced the first in the Evolution battery equipment line, the Muckmaster 300EB, a three cubic yard battery powered underground loader (LHD). The following year it introduced the Haulmaster 800-20EB, a 20 tonne battery powered underground haul truck. Both models have been working underground since their introduction and have proven their value to the mining industry. Reduced costs (ventilation, maintenance, and energy), a healthier work environment, and increased production are but a few of the benefits of battery electric mining equipment over traditional diesel machinery. Due to the success of their battery technology and performance of the previously developed models, RDH is introducing a larger, more powerful underground loader to its Evolution battery equipment line, the Muckmaster 600EB, the world’s first 6 yard capacity battery powered underground loader (LHD) for hard rock. Nearly five years of testing has provided the RDH team with knowledge that only underground working experience can provide. In keeping with their guiding design principle, “simplifying heavy equipment”, RDH has simplified and improved the battery system, ensuring a product for customers that is more economical and easier to operate and maintain. The Muckmaster 600EB has the same dimensions as the company’s standard 6 yard diesel loader and all of the features including ride control, enclosed operators cabin with AC and heat, remote control, and a camera...

RDH unveils battery-powered machines

August 13, 2013 by NORM TOLLINSKY In: Sudbury Mining Solutions Journal Eight loaders and three haul trucks sold to Kirkland Lake Gold RDH Mining Equipment has unveiled what is likely the first battery-powered load-haul-dump (LHD) machine for the underground mining market. Several years in development, the three-yard Muckmaster EB300 was showcased at the Canadian Institute of Mining and Metallurgy’s (CIM) 2013 convention and trade show in May. Development of the battery-powered loader was driven by Kirkland Lake Gold in order to quickly access new ore zones without having to spend millions of dollars on new ventilation raises, explained Kirkland Lake Gold president Brian Hinchcliffe. “Our COO, Mark Tessier, felt the technology was pretty mature, that we weren’t going too far out on the limb and that the rewards would be huge,” he said. It was a long process, recalled RDH president Kevin Fitzsimmons. “The prototype went on surface first and they got all of their operators to try it. Then it came back and we were asked to make some tweaks to it. It went to their health and safety committee, the Ministry of Labour was there… there were a lot of steps before it went underground in May 2012.” The first battery-powered loader to be put in service had chalked up a full year of moving muck in May, so both Kirkland Lake Gold and RDH felt the time was right to unveil it at the CIM, held in Toronto May 5, 6 and 7. Kirkland Lake Gold now has eight EB300s and three 20-tonne battery-powered haul trucks. Government regulations require 100 cfm of ventilation per horsepower for diesel...

Conveyor Haul Truck for Potash

RDH Mining Equipment announces the development of its conveyor haul truck, the Haulmaster 600-7LPC, designed specifically for low height seams. With units currently working in potash mining, operators and mine managers are praising its benefits and performance. The Haulmaster 600-7LPC’s conveyor built into the chassis moves the load towards the rear door without the risk of side spillage associated with the unloading of traditional haul trucks. The load mass is evenly supported by a series of robust crossbeams. Chains pull the conveyor to ensure a smooth, even and fail-safe operation.  Driven by hydraulic motors, the load is safely and steadily moved to the rear of the load body. In addition, the hydraulic control allows the operator to reduce conveyor speed or even stop it completely if needed.  When compared to traditional underground haul trucks the conveyor truck has a few specific advantages.  Because the load body is never lifted, the truck can work in low seams or under obstacles like ventilation or electrical, which is ideal for low ceilings as in potash mining. Units are currently working in a 70 inch heading.  There is no risk of tipping. The unit can unload on uneven surfaces or incline as the dump body is never lifted.  The conveyor system allows the unit to unload in a fraction of the time it takes a traditional dump truck. The low-maintenance truck is highly cost-effective, integrating a maintenance-free conveyor mechanism with sealed bearings. No downtime has been experienced in over one year of operation, ensuring the mines production targets are met.  Prior to the introduction of the conveyor belt truck, the mine used LHD’s...
