Patent number: 9512597Abstract: A device to actuate a contamination cover on a machine bracket is disclosed. The device may include a first transition cylinder mounted on the machine bracket and connected to the contamination cover, a transition circuit connected to the first transition cylinder for transmission of hydraulic pressure to the first transition cylinder; and a transition sensor coupled to the transition circuit to control the transmission of hydraulic pressure to the first transition cylinder. The activation of the transition sensor may permit the transmission of hydraulic pressure to drive the first transition cylinder for transition of the contamination cover from a close to an open position.Type: GrantFiled: September 3, 2012Date of Patent: December 6, 2016Assignee: Caterpillar Work Tools B.V.Inventors: Cornelius Antonius Maria Van Hooft, Dirk Jacobus Luyendijk, Holger Jongebloed
