Embodiment Construction

[0016] Before any embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of parts set forth in the following description or illustrated in the following drawings. The invention is capable of other embodiments and of being practiced or carried out in various ways.

[0017] figure 1 A hoist assembly 10 is shown comprising a hoist body 12; a first attachment member, such as a top hook 14 shown coupled to the hoist body 12; a second attachment member, such as shown coupled via a chain 18 to the bottom hook 16 of the hoist body 12; and a plurality of cables 20 coupled to the hoist body 12. The cable is operable to move the chain 18 relative to the hoist body 12 in response to user actuation. Thus, movement of the chain 18 relative to the hoist body 12 changes the distance between the bottom hook 16 and the hoist body 12 . Chain bag 22 is utilized to store e...

Abstract

An attachment assembly (24) for coupling a hoist body (12) to a support structure to selectively permit and inhibit rotation of the hoist body with respect to the support structure. The attachment assembly comprises an attachment member (14) including a first end and a second end, the first end connectable to the support structure, and the second end defining a shank (44) having a polygonal cross sectional shape, a receiving member that defines a through hole sized to receive the shank and permit rotation of the shank with respect to the receiving member, and a key member (30) defining a first circular aperture (40) and a second polygonal aperture (42) spaced from the first aperture, such that in a first position, the shank extends into the first circular aperture to permit rotation of the attachment member with respect to the receiving member and in a second position, the shank extends into the second polygonal aperture to inhibit rotation of the attachment member with respect to the receiving member.

Description

technical field [0001] The invention relates to winches and the connection between winches and machinery, tracks, arms or other structures. Background technique [0002] The hoist assembly in the prior art includes a hoist body, a top hook, a bottom hook, a cable and a chain. The cable is operable to move the chain relative to the hoist body to vary the distance between the bottom hook and the hoist body. However, the structure of the hoist assembly in the prior art is relatively complicated. Coordination of multiple components / parts is required to allow or inhibit rotation of the winch body relative to the top hook. Therefore, it is necessary to improve the hoist assembly in the prior art. Contents of the invention [0003] In one embodiment, the present invention provides a hoist assembly for aerial lifting. The winch assembly includes: an upwardly extending attachment member; a downwardly depending handle coupled to the attachment member and having a polygonal cross...
