Underground Loading Machines,
Built for Your Mine
Not for a catalog.
AMAC builds custom underground loading machines for coal and potash operations across the US and Canada. We design, build, and rebuild every loader to your mine's specifications, so the machine fits your conditions instead of the other way around.

— The Lineup
Our Underground Loading Machines
AMAC builds underground loading machines in two configurations: electrohydraulic gathering arm loaders for continuous face loading, and towed swing tail loaders for tight places where direct loading is not possible. Both are engineered around your seam height, entry width, and material, and both are supported through rebuild and parts for the life of the machine.
Gathering Arm Loader
LDM36E150 Loading Machine
A remote-operated electrohydraulic gathering arm loader rated at a nominal 1,800 to 2,000 tons per hour. 36-inch conveyor, boom articulates to 45 degrees, discharges up to 9 feet. Built for coal, potash, and salt.

Swing Tail Loader

A towed loading boom that swings up to 180 degrees behind a continuous or bore miner. Powered by auxiliary hydraulics from the miner or by electric power. Built for tight places where direct loading is not possible.

— The Difference
Built to your mine's conditions
Backed by over 40 years of underground OEM engineering. ISO 9001:2015 certified.
Custom Engineering
Where most manufacturers start from a standard platform, we start from your seam height, entry width, and material, and engineer the loader around them.
Reliable Support
Repairs, rebuilds, and replacement parts for loading machines, including units built by other manufacturers. Our Bessemer shop handles everything from component repair to full teardown rebuilds.
Underground Safety
Remote-controlled operation, multiple emergency stops, robust hydraulics, and optional proximity detection to keep material moving safely in confined underground spaces.
