Patent number: 10334211Abstract: An optical hazard detection system is described that may be used with an aerial device. The optical hazard detection system is utilized for determining a hazard in proximity thereto. The system comprises an optical sensor and a controller. The optical sensor is configured to capture optical images. The controller is configured to acquire the optical images from the optical sensor. The controller is also configured to identify a hazard at least in part from the optical images and to establish a hazard zone to prevent the utility platform from striking the hazard. The hazard zone is within a deployable range for the aerial device.Type: GrantFiled: November 22, 2016Date of Patent: June 25, 2019Assignee: Altec Industries, Inc.Inventor: Joshua T. Chard

Patent number: 9221660Abstract: A restraint system for restraining a worker to a platform of an aerial device comprises a restraint liner and a platform strap. The restraint liner includes four sidewalls, a floor, a lip, an interior anchor, and an exterior anchor. The floor may be coupled to one end of the four sidewalls, while the lip may be coupled to the opposing end of the four sidewalls and may extend therefrom. The interior anchor may be positioned on an interior surface of a first sidewall and operable to couple to a liner strap coupled to a worker. The exterior anchor may be positioned on an exterior surface of the first sidewall. The platform strap may be coupled to the exterior anchor and operable to couple to the platform.Type: GrantFiled: November 25, 2014Date of Patent: December 29, 2015Assignee: Altec Industries, Inc.Inventor: Joshua T.

Patent number: 7980359Abstract: An isolation mechanism for electrically isolating a control input mechanism of an otherwise substantially conventional boomed apparatus (12), such as, for example, an aerial device, digger derrick, or crane, having a workstation (14) coupled with a movable boom (16), wherein the isolation mechanism allows a worker to control movement of the boom (16) and positioning of the work station (14) while protecting against electrical discharge along substantially any path which includes the control input mechanism. In a first embodiment, the isolation mechanism takes the form of an improved control input mechanism (10), portions of which are constructed of or covered with an electrically non-conducting material. In a second embodiment, the isolation mechanism takes the form of a boom extension (110) constructed of or covered with electrically non-conductive material. In a third embodiment, the improved control input mechanism (10) and the boom extension (110) are combined.Type: GrantFiled: August 25, 2008Date of Patent: July 19, 2011Assignee: Altec Industries, Inc.Inventors: Joshua T. Chard, Edman R. Blair
