Leveling system for lift device
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.

Upright post structure and automobile elevator
The invention relates to the field of automobile elevators. An upright post structure is provided, wherein the upright post structure is a polygonal columnar structure formed by bending a plate, the upright post structure comprises a back plate, both ends of the back plate in a width direction vertically extend toward the same side of the back plate to form a side plate, end parts of the side plate away from the back plate extend oppositely to form a front plate, wherein the upright post structure further comprises one or a combination of various. Thus, when the upright post structure is subjected to a force in a horizontal direction, the local stress of the upright post is transferred so that the strength of the upright post is improved. The invention further provides automobile elevator using the upright post structure.

Storage systems
Disclosed are various embodiments of storage systems. In some embodiments, the storage system includes an upper frame, a guide tube that supports the upper frame, a pivot arm, and a side support. A first end of the pivot arm is rotatably coupled to the guide tube, and a second end of the pivot arm is rotatably coupled to a fixed pivot point. The side support includes a guide post that is inserted into the guide tube. The guide tube is configured to move along the guide post.
LEVELING SYSTEM FOR LIFT DEVICE
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. The first leveling assembly includes a first pair of actuators positioned to facilitate a first pitch adjustment and a first roll adjustment of the first end of the chassis. The second leveling assembly includes a second pair of actuators positioned to facilitate a second pitch adjustment and a second roll adjustment of the opposing second end of the chassis. The control system is configured to (i) actively control the first pair of actuators and the second pair of actuators during a first mode of operation, and (ii) actively control the first pair of actuators and facilitate passive control of the second pair of actuators during a second mode of operation.
