An article transport facility includes an article transport vehicle which is suspended from and supported by one or more travel rails supported by a ceiling, and is configured to suspend and support an article, and to transport the article from a support platform that serves as a transport origin to another support platform that serves as a transport destination. This article transport facility has an adjusting-purpose support platform which includes an adjusting-purpose support surface on which an adjusting-purpose device, which is used for a purpose of adjusting transporting-purpose profile information, can be placed in the same manner in which an article is placed on a support platform. The adjusting-purpose support surface is capable of being moved such that a height thereof can be varied continuously between an upper limit height and a lower limit height specified in advance.

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 tower crane for assembling a wind turbine includes a boom assembly including a boom and a hoisting block coupled to the boom, an extendable tower assembly including a plurality of tower sections, and a transport assembly including a central support frame coupled to the tower assembly, a self-propelled transporter configured to transport the tower crane, and a diagonal brace extending between the central support frame and the transporter, wherein the diagonal brace includes a linear actuator configured to selectably extend and retract the diagonal brace.

A boom lift includes a base having a first end and an opposing second end, a turntable coupled to the base, a boom coupled to the turntable, an assembly pivotably coupled to the first end of the base, and a first actuator coupled to the first end of the base and the assembly. The assembly includes a tractive element. The assembly extends from the base such that the tractive element is longitudinally offset from and spaced forward of the first end and the opposing second end of the base.

A crawler type crane having a base carrier unit having a control unit associated therewith and an upper portion assembly having a boom portion coupled at end to the base carrier unit and to a jib portion at an opposed end. The boom portion includes one or more selected boom sections that are articulatable relative to each other. The crane also includes a multi-function attachment unit that is coupled to the jib portion and has a grappling unit for grasping a work piece and a saw attachment unit for cutting the workpiece. The crane can also include a first fluid regulating device coupled to the jib portion for regulating a fluid to the jib portion and to the multi-function attachment unit and a second fluid regulating device coupled to the boom portion for regulating a fluid to the winch element and to the multi-function attachment unit.

A lift device includes a chassis having a first end and an opposing second end, a first actuator coupled to the first end, a second actuator coupled to the first end, a third actuator coupled to the opposing second end; and a fourth actuator coupled to the opposing second end. The first actuator and the second actuator are selectively engageable to facilitate providing active control of a first pitch adjustment and a first roll adjustment of the first end of the chassis. The third actuator and the fourth actuator are (i) selectively fluidly couplable to facilitate providing passive control of a second pitch adjustment and a second roll adjustment of the opposing second end of the chassis and (ii) selectively fluidly decouplable to facilitate providing active control of the second pitch adjustment and the second roll adjustment of the opposing second end of the chassis.
