Publication number: 20140166953Abstract: A hoist rotation limiting system for a hoist. A hoist drum has a grooved exterior surface configured to position a cable in a predetermined position relative to the ends and longitudinal axis of the hoist drum as the cable is wound onto or off of the hoist drum. Upon the cable being positioned in the predetermined position, the cable urges portions of a carrier weldment to contact a switch, thereby sending an electrical signal to stop rotation of a hoist motor.Type: ApplicationFiled: December 18, 2012Publication date: June 19, 2014Applicant: LONGYEAR TM, INC.Inventors: CHRIS WRIGHT, STEFAN WREDE, JOSHUA BYRON

Patent number: 8408328Abstract: A hydraulic control system includes a first motor, a second motor, a pump operatively associated with the first motor, a first coupling valve operatively associated with the second motor, first parallel valves operatively associated with the second motor, and a first switching valve operatively associated with the first coupling valve and the first parallel valves. The first switching valve is configured to switch the first coupling valve between a first coupling state and a second coupling state opposite the first coupling state and to switch the first parallel valves between a first parallel state and a second parallel state opposite the first parallel state. While the first parallel valves are in the first parallel state a portion of the output of the first motor drives the second motor while the first parallel valves are in the second parallel state, the output of the pump drives the second motor.Type: GrantFiled: May 7, 2012Date of Patent: April 2, 2013Assignee: Longyear TM, Inc.Inventors: Stefan Wrede, Christof Kruse
