    摘要： An aerial device for operating on energized powerlines is disclosed. Embodiments of the current disclosure relate to a slew drive system for an aerial device. In some embodiments, the slew drive system provides leveling and jerk mitigation to an aerial platform of the aerial device. Various sensors may be disposed on an aerial device boom, on the slew drive, and on the aerial platform, for obtaining data indicative of a state of the aerial device. The data indicative of the state of the aerial device may be used to control the slew drive with various hydraulic valves and motors to level the aerial platform and mitigate/eliminate jerk. The systems and methods described herein provide a comfortable riding experience for aerial line workers in the aerial platform and maintain a level state of the aerial platform across a wide range of boom angles including at extreme ends of the boom assembly.

    摘要： A fire apparatus includes a chassis and a ladder assembly coupled to the chassis. The ladder assembly includes a first ladder section, a second ladder section slidably coupled to the first ladder section, a first support pivotably coupled to the first ladder section, and a second support fixedly coupled to the first ladder section. The first support and the second support are each configured to limit vertical movement of the second ladder section relative to the first ladder section.

    摘要： One variation of a method for monitoring lift events at a construction site includes: deriving a lifting profile from a first timeseries of load values, output by a load sensor coupled to a crane hook, during a first time period; deriving an oscillation characteristic from a first timeseries of motion values, output by a motion sensor coupled to the crane hook, during the first time period; identifying a type of an object carried by the crane hook during the first time period based on the lifting profile and the oscillation characteristic; selecting a load handling specification for the object based on the type of the object; accessing a second timeseries of motion values output by the motion sensor during a second time period; and, in response to the second timeseries of motion values deviating from the load handling specification, activating an object motion alarm for the object.

    摘要： A lift device includes a chassis, a platform configured to support a user, a lift assembly coupling the platform to the chassis, an actuator configured to at least one of (a) move the platform relative to the chassis or (b) propel the chassis, a sensor assembly, and a controller. The sensor assembly includes a bar including a first end portion coupled to the platform and a second end portion opposite the first end portion and a housing defining an aperture sized to receive the second end portion of the bar. The sensor provides a signal in response to at least one of (a) the second end portion of the bar contacting the sensor or (b) the second end portion of the bar exiting the aperture. The controller is operatively coupled to the sensor and the actuator and configured to control the actuator based on the signal from the sensor.
