Plowmaster

Plowmaster Mining

In modern plow systems operated with 42x137 mm round link chains at speeds of up to 3.6 m/s, the chain connectors are subject to much higher operational demands. In order to extend the operating life of the plow chain connectors, THIELE, with the support of FEM-Analysis, has developed a new concept. After assessing numerous trial applications in high-performance operations underground, THIELE has optimized the design of the PLOWMASTER®, bringing it to operational maturity.


The THIELE PLOWMASTER® runs in the shadows of the plow chain, and is therefore protected from the formation of any contact fractures which may otherwise occur as a result of abrasive contact during operation. The PLOWMASTER®’s lock remains easy to open, even after long runtime.
