A mechanical leg comprises a frame, a retractable member, a wheel, an extension and retraction driving member, a travel driving member, an auxiliary leg, and an auxiliary wheel. The extension and retraction driving member is located on a side of the frame. The retractable member is connected to the extension and retraction driving member. The wheel is connected to the retractable member. The wheel is further connected to the travel driving member. A first end of the auxiliary leg is connected to the auxiliary wheel, and a second end of the auxiliary leg is located on the frame. The retractable member extends under the driving of the extension and retraction driving member to drive the wheel to jump. The wheel is driven by the travel driving member to move. When the auxiliary wheel contacts the ground, the mechanical leg moves with the rolling of the wheel and the auxiliary wheel.

A leveling system for a lift device includes a control system. The control system has programmed instructions to acquire operation data regarding operation of the lift device, fluidly couple a first leveling actuator and a second leveling actuator based on the operation data, acquire an update regarding the operation data, fluidly decouple the first leveling actuator and the second leveling actuator based on the update regarding the operation data, and selectively control the first leveling actuator and the second leveling actuator to (i) selectively reposition a first tractive element and a second tractive element relative to each other about a longitudinal axis defined by the lift device and (ii) selectively reposition the first tractive element and the second tractive element about a first lateral axis defined by the lift device.

A suspension system including four dampers is disclosed where each damper includes a compression chamber and a rebound chamber. A first hydraulic circuit includes a front hydraulic line, a rear hydraulic line, and a first longitudinal hydraulic line that extends between and fluidly connects the front and rear hydraulic lines of the first hydraulic circuit. A second hydraulic circuit includes a front hydraulic line, a rear hydraulic line, and a second longitudinal hydraulic line that extends between and fluidly connects the front and rear hydraulic lines of the second hydraulic circuit. First and second longitudinal comfort valves are positioned in the first and second longitudinal hydraulic lines, respectively, between the front and rear hydraulic lines. Both of the first and second longitudinal comfort valves are electromechanical valves and can be actuated to couple and decouple front axle roll control from rear axle roll control.
