CONTINUOUS HAULAGE SYSTEMS
For over twenty years, Prairie Machine’s line of Continuous Haulage equipment has been an integral component in the most productive soft rock mines across the world. Spearheaded by the Flexiveyor, this customizable product line works in conjunction with any mining equipment infrastructure to provide a safe, automated, and continuous flow of ore, no matter the environment.
FLEXIVEYOR
The customizable Flexiveyor works in conjunction with any mining machine to provide a safe, automated, and continuous flow of ore.
The Flexiveyor is designed to continuously convey ore and tram around corners as sharp as 50⁰ with minimal operator supervision.
The Miner Follower system allows the Flexiveyor to automatically follow any mining machine through all corners of the mine, all while maintaining a throughput rate of up to 1200 tons of ore per hour.
Available in multiple configurations, the Flexiveyor is custom to contain an endless number of individual conveyor cars.
- The tried and tested Standard Flexiveyor is the ideal haulage solution in conventional mining environments.
- The Low-Profile Flexiveyor brings the same continuous haulage power to mines with limited access.
- The compact Narrow Flexiveyor integrates seamlessly into mines with restricted entry ways and work areas.
- With greater ground clearance, the Straddle-Over Flexiveyor is ideal for narrow mines with reduced access or with unstable ground conditions.

BELTLINE CLEAN-UP FLEXIVEYOR
The Beltline Clean-Up Flexiveyor ensures that no ore goes to waste.
The versatile Beltline Clean-Up Flexiveyor is engineered to follow any mining machine and to collect ore from the floor behind it and to collect any run-off from below a site's stationary conveyor belt system.
Each of the 3 cars found in this Flexiveyor system has independent steering and conveyor belt systems. The Beltline Clean-Up Flexiveyor can be turned to convey in any position and provides maximum ore output with minimal operator supervision.

FLEX BRIDGE
The versatile Flex Bridge offers continuous haulage through confined spaces.
The Flex Bridge is a series of overlapping, extendible conveyor sections that convey ore from any mining machine to a mine site's stationary conveyor belt system. Each section of the Flex Bridge can operate independently or can be controlled as one synchronized unit to continuously haul ore through confined spaces.
The Flex Bridge discharge car straddles the mine site's stationary conveyor belt structure while the intermediate and load cars can be extended, retracted, and angled to meet a site's specific conveyance needs.
