Innovation to the Core

For over a century, we have been North America’s preferred supplier of custom, proven and reliable underground material handling systems. We build mine skips, rail cars, mine personnel cages and other underground haulage equipment painstakingly designed to withstand the most demanding working conditions. Through our unrivalled combination of industrial manufacturing expertise, innovative engineering and outstanding technical support, we consistently exceed customer expectations with every product we produce.

Custom Design & Engineering
The challenges that the mining industry faces can vary significantly from one location to the next. Underground material handling and haulage systems typically require customized designs to meet the specific requirements of a particular mining operation. We specialize in custom-producing mining skips, cages and other conveyance systems to meet our customers’ unique needs for productivity, safety and reliability. Our engineers are equally adept at refurbishing earlier equipment designs to improve the performance and safety of existing mine haulage systems.

Our designs and manufacturing processes strictly comply with all industry-related quality certifications including ISO 9001, CWB (fusion welding of steel structures, fusion welding of aluminium, certified welding inspection) and APEO Certificate of Authorization.

Automation

We have invested heavily in automation technologies to ensure mining firms can keep pace with the ever-evolving demands placed on its crucial role in the supply chain. Our automation solutions involve the sequential linking of operations over a significant number of individual equipment pieces. Often, automation reduces the amount of human involvement required to accomplish a task. Automation is also an effective tool for maximizing efficiency and improving safety.

Our approach

  • Interlocking of functions – each operation can only proceed if specific communication protocols are satisfied.
  • Redundancy – important interlocks must be arranged so that all permissions have been properly scrutinized within the process.
  • Flexibility – adding and removing system functions should be done with ease while maintaining overall system integrity.
  • Reliability – maximizing the use of digital components versus hard-wired systems.
  • Simplicity – understanding system operation and capturing critical interlocks with the least number of steps.

Material handling system automation can play a dramatic role in how operations function in an underground mining environment.

Cages

No two mining operations are the same. And no two Wabi mine cage designs are the same. Our engineers will visit your mine site to ensure that the mine shaft cage we design and manufacture satisfies your unique operational and load requirements. One thing always remains the same: every mine cage features the highest quality materials, dependable systems and components, and is designed to endure the harshest working conditions.

We can also reconfigure existing cages to accommodate any changes to operating requirements that may occur. A certificate of load capacity stamped by a professional engineer accompanies all mine shaft conveyances we manufacture. We also offer Conveyance Inspection Service to guarantee that your mine personnel cage complies with all safety guidelines.

We design and manufacture many mine cage styles including:

  • Single and multiple deck compartment configurations
  • Two or four-guide configurations
  • Compartment configurations manufactured in steel or aluminum

Loading & Dumping Systems

We excel in enabling our clients to handle broken rock with maximum efficiency and minimum effort. Whether the application is run-of-mine muck, crushed rock or comminuted ore, our expertise in controlling muck streams is unparalleled.

We use tried and true rules of thumb for chute and control gate designs, and validate our non-conventional designs with Discrete Element Modelling (DEM). We employ our proprietary material, MET500, for wear linings in hard-to-access areas as it outwears traditional quenched and tempered wear plate materials by up to five times.

We design and manufacture many mine loading and dumping system styles including:

  • Skip loading stations
  • Skip dump chutes

Shaft Guidance
Guide Roller Suspension Bracket

Shaft guidance systems operate on rigid guide strings that require a systemic approach for maximum efficiency. This guidance system involves coupling the guide roller bracket design with guide wear shoe operating clearances. Active guide roller suspension and load absorption require adequate operating clearance between guide slippers and the shaft compartment guide string.

The design philosophy is that the guide roller bracket is allowed to deflect before the guide slipper contacts the guide string surface. This deflection before impact is critical to absorbing the energies imparted into the guidance system, ensuring smooth vertical travel for the shaft conveyance.

Contact us now and consult with our engineering team on the shaft guidance system best suited to your operations.

Rigid-Mount Guide Roller Bracket

Our rigid-mount guide roller system offers a novel approach to shaft conveyance guidance. The system enables a simpler mode of operation versus comparable systems for greater efficiency and travel stability when encountering misalignment conditions in the shaft compartment guide string.

With our proprietary design, the position of the rolling element is captured in a fixed position by the rigid bracket. When the rolling element is in contact with the guide string surface, energy absorption is accomplished through the rolling element only. The main advantages of a rigid-mount bracket design include simplicity of operation and lightweight construction.

Contact us now and consult with our engineering team on the roller brackets best suited to your operations.

Lock-N-Load® Cage Holding System

We live and breathe to innovate new efficiencies in mining operations. In working closely with our clients, we recognized the challenges posed by rope stretch when holding a mine cage firmly in place during loading and unloading.

Our solution is the proprietary Lock-N-Load cage holding system, an innovation achieved through the use of advanced technology with lightweight hydraulic clamps and very rapid clamping times. Proportional control valves ensure a controlled clamp release on system deactivation as the conveyance takes up the resultant rope stretch.

Contact us now and consult with our engineering team on the unrivalled benefits of our exclusive Lock-N-Load system.
