摘要:
A chain hoist (10) having an improved chain guide (12) for a link chain (14). The chain guide (12) has a channel (36) with a cross-shaped cross section, through which the link chain (14) extends. An end surface (26) of the chain guide (12) extends away from a mouth opening (28) of the channel (36). The channel (36) establishes a through-passage direction (D) which widens in the direction of the end surface (26), and a protrusion (30) is formed on the end surface (26) around the mouth opening (28) of the channel (36).

A invention relates to a chain shackle for fastening a hoist chain of a chain hoist to a hoisting member or the chain hoist. The chain shackle includes two identical shackle halves installable against each other to work together in such a manner that they form between them a first space for one chain loop or chain loop half of the hoist chain to lock it against the hoisting direction or force. The first space is open in a first direction in the longitudinal direction of the chain shackle. A second space is connected to the first space and intended for a second hoist chain loop that is coupled with the first chain loop or is to be coupled with a chain loop half. The second space is open in both longitudinal directions of the hoist chain.

A low profile transport device includes a frame having a top surface and a recess disposed along the top surface to hold and transport an object. The low profile transport device also includes a plurality of wheels disposed below the frame that support the frame, and a plurality of pivotable wheel struts coupled to the wheels. The wheel struts are each individually adjustable relative to the frame from a first position relative to the frame to a second position relative to the frame to allow the low profile transport device to climb an obstacle without tilting the frame. The low profile transport device also includes a motor that generates movement of the wheels.
