An inclination sensor system for a mobile work machine includes a MEMS inclination sensor and a further inclination sensor of a different type and a fusion device. The inclination sensor is configured to output a first inclination signal on the basis of an inclination that exists at the inclination sensor. The further inclination sensor is configured to output a second inclination signal on the basis of the inclination that exists at the further inclination sensor. The fusion device is configured to calculate a corrected inclination signal on the basis of the first and second inclination signals and to output same as the corrected inclination signal.

A lift device includes a base, a platform configured to support an operator, and a scissor assembly coupling the base to the platform.

The first inner arm is configured rotate relative to the first outer arm about a first middle axis. The first scissor layer has a first end axis center point. An actuator is configured to move the platform between a fully raised position and a fully lowered position relative to the base. The first middle axis is offset vertically from the first end axis center point.

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 rod including a first end portion coupled to the platform and a second end portion opposite the first end portion, a housing defining an aperture sized to receive the second end portion of the rod, and a sensor coupled to the housing and configured to provide a signal in response to the second end portion of the rod exiting the aperture. The controller is operatively coupled to the sensor and the actuator and configured to control the actuator in response to receiving the signal from the sensor.

A machine localization system includes a work machine including an extendable implement, a first pressure sensor coupled to the work machine, a second pressure sensor located at a known elevation, and a computing system operably coupled to the work machine, the first pressure sensor, and the second pressure sensor. The computing system is configured to receive a first pressure measurement from the first pressure sensor and a second pressure measurement from the second pressure sensor, determine a maximum operating height of the extendable implement based on a difference between the first pressure measurement and the second pressure measurement, and configure the extendable implement to not exceed the maximum operating height.

A fire apparatus includes a chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a ladder assembly coupled to the chassis, and a stability system. The stability system includes at least one of (i) a front downrigger coupled to the chassis, (ii) a rear downrigger coupled the chassis, or an outrigger coupled to the chassis. The stability system is controllable to facilitate leaning the fire apparatus at least two degrees relative to a ground surface while maintaining full operational capability of the ladder assembly.

An intelligent platform may employ a unitary platform positioned between articulating legs with each articulating leg connected to a leveling module. The leveling module can be configured to execute a leveling strategy that involves extending at least one articulating leg to establish the unitary platform in a level orientation relative to an underlying, non-level terrain.

A system includes a platform having an upper surface and defining a recess having a floor, the recess configured to seat a dish, and a movable securing frame that is movably connected with the platform, the frame including a lift support having an upper surface that is movable along a path from a first location that is beneath the floor of the recess, through the recess, to a second location that is coplanar with the upper surface of the platform. A motor configured to cause oscillation of the platform and the movable securing frame can be used. A method of using the system can include placing a dish above a recess defined by an upper surface of a platform, and lowering the frame with respect to the platform, thereby seating the dish within the recess.

The present disclosure discloses an automatic leveling control method for a four-leg support working platform, which comprises the steps: determining the mass center position of the working platform, determining the main bearing quadrant and distinguishing active legs from the driven leg; adjusting the driven leg to weak state, controlling all legs to synchronously actuate for leveling; calculating the limit compensating actuation length of the driven leg, and performing compensating actuation until accomplishing the leveling process. The method is advantageous in: high speed, high robustness, no repeated oscillation. The mass center always stays within the bearing zone of the active legs, thus completely eliminating capsizing risk of the working platform. The compensating actuation of the driven leg ensures there is no weak leg, and hence high attitude and load-bearing stability of the working platform is achieved.

A safety interlock system includes a safety harness comprising a plurality of buckles to secure the harness to a user and a safety attachment ring. A fall-arrest belt clip is configured to be releasably attached to the safety attachment ring, the fall-arrest belt clip attached to a fall-arrest tether of a machine. The system further includes a safety interlock means for disabling an operation of the machine when the fall-arrest clip is detached from the safety attachment ring, the machine coupled to the fall-arrest tether.
