A mounting rib for an elevating platform, the rib designed and configured to insert through a slot in the sidewall of the elevating platform. The rib is composed of a T-shaped and two L-shaped components, wherein the T-shaped component inserts through the slot and the L-shaped components are attached on the exterior of the platform. Also, a corner-mounted rib for an elevating platform.

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.

Mounting plates for elevating platforms, including a mounting plate with interior and exterior reinforcement pieces elongated vertically and with rounded corners; a single-piece mounting plate inserted through slots in the platform wall; and a single-piece mounting plate with top and side tabs that wrap around the platform exterior to transform tension stress into shear stress.

A lift machine includes a base having a first end and a second end, a first assembly, and a second assembly. The first end has first and second pivot points defining a first lateral axis. The second end has third and fourth pivot points defining a second lateral axis. The first assembly is pivotably coupled to the first and second pivot points. The first assembly extends away from the base in a first direction such that first and second tractive elements are longitudinally offset from the first lateral axis and spaced from the first end of the base. The second assembly is pivotably coupled to the third and fourth pivot points. The second assembly extends away from the base in a second direction such that third and fourth tractive elements are longitudinally offset from the second lateral axis and spaced from the second end of the base.

A lifting device includes a chassis, a turret connected to the chassis so as to rotate around a vertical axis, and a lifting arm, extending between a first end connected to the turret, and a second end connected to a unit for carrying the load. It includes a first sleeve and a second sleeve, each able to receive a respective fork, arranged on the chassis, on either side of the turret, parallel to one another.

A machine includes a chassis, a turntable coupled to the chassis, a boom coupled to the turntable, an axle, a first actuator, and a second actuator. The chassis has a first end and an opposing second end, and defines a longitudinal center axis. The turntable is selectively rotatable about a rotation axis. The axle is pivotally coupled to the first end of the chassis and configured to pivot about the longitudinal center axis. The first actuator is coupled to the first end of the chassis and positioned on a first side of the longitudinal center axis. The first actuator is extendable to selectively engage a first contact point on the axle. The second actuator is coupled to the first end of the chassis and positioned on an opposing second side of the longitudinal center axis. The second actuator is extendable to selectively engage a second contact point on the axle.

A method of operating a construction machine that includes a base, support arms each pivotally coupled to the base, and a plurality of wheel assemblies each coupled to the one of the support arms, the method including, in a transport mode of the construction machine, turning a wheel of each of the wheel assemblies, independently from a wheel of another of the wheel assemblies, to a toe out orientation. The method also includes driving each support arm to a deployed condition of the support arm in an operational mode of the construction machine. Driving each support arm to the deployed condition causes the distal ends of each of the support arms to move away from one another and outwardly from the base. The method also includes locking each support arm in the deployed condition and controlling steering of each wheel in the operational mode of the construction machine.

A lift device includes a chassis, a boom pivotally coupled to the chassis, a first leveling assembly pivotally coupled to a first end of the chassis, a second leveling assembly pivotally coupled to an opposing second end of the chassis, and a control system.
