The power, durability and versatility of Thern power winches means that bulk handling and mining operations can turn to one place for innovative load handling solutions – Thern, Inc. A coalmine operation needed to lift a 50-ton conveyor counterweight during routine maintenance of the conveyor. The counterweight is housed in a take up tower at the end of the conveyor where it is suspended, using gravity to maintain tension to on the belt. To perform the scheduled conveyor maintenance, crews needed to lift the counterweight to release this tension and access the conveyor. A custom conveyor maintenance winch system from Thern, Inc. provided an economical and reliable solution with the capacity to lift the large counterweight.

Thern’s Stabbing Board Winch delivers the rugged and reliable performance drilling rig operators need, in the compact package they require. During drilling operations, rig crews need to quickly, reliably and repeatedly pull sections of drill pipe from holding racks located on the derrick tower and position the pipe over the drill shaft for attachment to the drill head. As the drill penetrates deeper, additional pipe segments are added to continue drilling. Pipes are positioned from a work platform or stabbing board on the derrick tower where space is extremely limited, making large positioning systems prohibitive. The Stabbing Board Winch from Thern, Inc. provides rig operators a compact and reliable solution for positioning drill pipe.
