摘要

Bucyrus has improved nonproductive long-wall move time with the introduction of a variable frequency drive (VFD) to its Vers-A-Trac 650 model. Since its introduction in 2004, approximately 50 of the successful roof support carriers have been shipped. The Vers-A-Trac 650AC features the Bucyrus HiPACIO control system and represents the latest generation of heavy roof support carriers. The Bucyrus HiPACIO control system is an innovative variable frequency inverter drive that allows costly dc motors to be replaced by higher power, more efficient ac motors. Traction power is increased by 100 percent and hydraulic power by nearly 300 percent. These increases, in turn, nearly double loaded traction speed and gradeability and improve hydraulic performance.
