SP-S Connectors


The SP-S Connector is an advanced development of the well proven SP-Connector-Design, with major improvements achieved by incorporating a new center lock that features a bolted connection. The “S“ in the name denotes the bolted connection. New are also the conical contact surfaces which hamper to cake both connector halves and support the disassembly. The new locking system comprises of matching and interconnecting profiles that rotate on the same axis, thereby eliminating the risk of misalignment. This design allows for easy assembly and dismantling.

PLOWMASTER®-S

Plowmaster Mining 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®-S, bringing it to operational maturity.


The THIELE PLOWMASTER®-S 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 screw lock of the PLOWMASTER®-S remain easy to open, even after long runtime.
