Proven technology from experienced Mine Shaft Cage manufacturers

  • Our cages range from very small Two-Man Auxiliary Cages and Trailer Cages operating on two guides, to large Multi-Deck Four-Guide Cages handling 300 persons or more, or internal loads of trucks, equipment and material exceeding 50 tons.
  • Cage construction materials include aluminum, mild steel, stainless steel and combinations of each.

  • Designed for versatility, multiple cage floor, door, roof, removable intermediate deck and removable counterweight options are available. Cage chairing mechanisms also available. Integral cage configurations or bail/bridle-type designs with removable cage pods are available.

  • For double-drum or friction hoist applications, our counterweights are designed for optimal balancing of the cage in both loaded and empty conditions within the range of friction available on the hoist. Tailored to your specific demands, individual weights can be added or removed as necessary to adjust ballast configurations for heavier loads and expand the overall range of possible payloads. The ballast is positively positioned and secured into the counterweight bail. FLS counterweights also convince with their robust steel construction that ensures a durable and heavy-duty design, in which shaft inspection platforms can be integrated into as well.

  • We provide Inspection Canopies and Work Platforms custom tailored for each conveyance and maintenance requirement. This offers you maximum safety, ensuring overhead protection and creating a safe working area when performing shaft inspections and maintenance. Our Inspection Canopies and Work Platforms are typically of lightweight aluminum construction in separate sections. This allows for easy installation and removal and minimises tare weight during regular operation of the conveyance. Furthermore, roll-on and lift-on styles are available.

  • For cages operating with single rope drum hoists, we provide Safety Mechanisms for either wood or steel shaft guides; cages can also be designed to operate with a multi-rope Koepe hoist.

  • We offer additional rope attachments and safety equipment, such as Catch Gears to catch and hold the conveyance in an extreme overwind situation, and Arrestor Frames for the head frame and shaft sump, designed to create a predictable deceleration and bring the conveyance to a stop in the event of a hoist problem.

  • Several types of Guide Rollers and Suspension Systems are available to best suit the conveyance requirements and shaft conditions.
