WINONA, Minn., September 24, 2003 – Loading chute systems are judged by how accurately, quickly and dependably they get into position, hold steady and move to their next position. Thern power winches not only make all these things happen, but they do so more efficiently and effectively than complicated hydraulic systems or mechanical gear systems.In a typical installation, two separate Thern winches control height and extension of the chute arm. Winches are equipped with limit switches and standard brakemotors for complete and pinpoint control throughout the loading operation. The range of sizes, mounting options and other design parameters assure a smooth fit with any loading system configurations.Thern, Inc. is a major designer and manufacturer of winches, cranes and hoists for virtually unlimited industrial applications. Founded in 1948, Thern is headquartered in Winona, MN and markets its products worldwide.
