Abstract: A lift device includes a chassis having a first end and an opposing second end, a first actuator coupled to the first end of the chassis, a second actuator coupled to the first end of the chassis, a third actuator coupled to the opposing second end of the chassis, a fourth actuator coupled to the opposing second end of the chassis, and a control system. The control system is configured to fluidly couple at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator, and fluidly decouple and actively control the at least two of the first actuator, the second actuator, the third actuator, and the fourth actuator.

Abstract: A lift device includes a chassis, tractive elements, a platform including a deck, a lift assembly, and a stair assembly. The lift assembly is configured to move the platform between a lowered position and a raised position. The stair assembly is coupled to at least one of the platform and the chassis and includes a first support and a second support extending parallel to one another. The stair assembly is repositionable between a stored position and a deployed position and facilitates access to the deck from the ground when in the deployed position. The first support extends farther outward horizontally than the second support relative to the chassis when the stair assembly is in the deployed position. The first support extends farther outward horizontally relative to the chassis when the stair assembly is in the deployed position than when the stair assembly is in a stored position.

Abstract: A telehandler includes a frame assembly, tractive elements, a cabin, a boom assembly, and a locking mechanism selectively reconfigurable between a locked configuration and an unlocked configuration. The boom assembly includes a base boom section having a proximal end pivotably coupled to the frame assembly and a distal end opposite the proximal end, an intermediate boom section pivotably coupled to the distal end of the base boom section, and an upper boom section having a proximal end pivotably coupled to the intermediate boom section and a distal end configured to be coupled to an implement. The boom assembly is configured to move freely when the locking mechanism is in the unlocked configuration. In the locked configuration, the locking mechanism is configured to couple the intermediate boom section to the frame assembly such that the locking mechanism limits rotation of the base boom section relative to the frame assembly.

Abstract: A leveling assembly for a lift device includes a carrier arm, an axle, a first actuator, and a second actuator. The carrier arm includes a base that defines a first interface configured to pivotally couple the carrier arm to a chassis of the lift device to facilitate a pitch adjustment of the leveling assembly, a projection that defines a second interface, and a transition that extends angularly between the base and the projection such that the projection is elevated relative to the base. The axle defines a third interface positioned to engage with the second interface to pivotally couple the axle to the carrier arm to facilitate a roll adjustment of the leveling assembly. The first actuator is pivotally coupled to a first lateral end of the axle. The second actuator is pivotally coupled to an opposing second lateral end of the axle.
