Specialist steel doors for the mining sector

With an increase in mining operations, Australian mine sites appraised their requirements for door openings to onsite maintenance facilities.

Historically, mine sites had large open sheds primarily used to carry out service and maintenance of mining equipment and large mining vehicles. Due to the nature of mine sites, there were several issues surrounding working in a large, open-sided shed. These included dust, extremes of temperature, wind and rain.

To meet the changing requirements of the industry and workplace and as a result of significant improvements in mine safety, it was necessary to investigate ways to improve work conditions. Large steel doors were installed to the work sheds so the area could be sealed off.

When the maintenance sheds were enclosed, they provided maintenance workers the benefit of a controlled working environment. Servicing time for regular maintenance procedures was reduced. There were also benefits to equipment, vehicles and to the sheds themselves. When protected from the elements, all have a longer lifespan.

As the mining industry changed, oversized machines with a large capacity were introduced for high production efficiency and to meet customer requirements. To enable entry of large dimension mine vehicles, and taking into account the severe weather conditions on some mine sites, mine doors had to be engineered to accommodate the larger vehicles and to have the ability to withstand high wind loads.

Monarch Renlita Overhead Doors (Monarch) is an Australian business with over 45 years’ experience designing and manufacturing large-scale specialist steel doors. Monarch doors are widely used in mine sites throughout Australia.

Monarch doors have a reputation for their strength and durability. Our doors are rugged and they have an outstanding performance record under harsh conditions. Monarch offers dependable and robust doors that provide security and smooth, effortless operation for the large-scale door openings required on mine sites.

Our doors span up to 30 metres and are engineered to withstand high wind loads.

We design our doors alongside the building designer, working around the crane beams to ensure the crane access and operation is not obstructed. Vertical slides are a perfect solution when dealing with crane access. The vertical doors slide between the crane beam and the outside of the building, effectively freeing the path of the crane.

Our doors are manufactured offsite and when delivered require minimal installation works and in turn, there is only a small amount of disruption to the site. Once installed, due to the high quality and robust design of Monarch Doors, very little servicing is required.

The Monarch Renlita Series 5000 vertical sliding counterweight balanced single-leaf door and the Monarch Renlita Series 3000 foldaway two-leaf door are ideal for mine buildings. Features include:

  • Individually designed and manufactured to achieve exact counterweight balance for safety and appearance.
  • Clad vertically with COLORBONDR ribbed sheeting, e.g. Trimdek and Spandek.
  • Complete with Zincanneal steel counterweight casings.
  • Suit opening sizes up to 30 metres.
  • Suitable for power operation: All doors incorporate the Renlita heavy duty drive electric operation system, designed to fully open or close the door at approximately 6-7 seconds per metre of opening height, using a continuously rated 3 phase motor, close-coupled to a matched reduction gearbox.

Monarch forms part of the ARA Group, a Group of companies specialising in building and infrastructure services for industrial, commercial and government markets.

Monarch has offices and manufacturing facilities around Australia.
