Abstract
Abstract A wheeled hoist is illustrated having a base portion which may be readily disassembled for shipment having a tray forming a transverse frame for carrying a rearwardly inclined post or standard and a longitudinal base portion, all supported by wheels. The post carries a boom which may be mounted directly within the post to be raised and lowered, and the post is removably mounted to distribute an axial load to the base.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
207 words
A wheeled hoist having a base formed from a transverse base member, and a longitudinal base portion extending forwardly from said transverse base member; said base being supported by wheels, comprising: a post carried by said base and being inclined rearwardly toward said transverse base member; means supporting said post carried by said transverse base member on one end and tapering inwardly toward and being removably connected to said post on the other end; one of a pair of transverse structural section forming a part of said base having a surface at substantially a right sngle to said post; fastening means removably securing said post to said surface at substantially a right angle thereto to transmit an axial load in bearing thereon; a boom mounted to be raised and lowered carried adjacent an upper end of said post extending outwardly above and in alignment with said longitudinal base portion; said longitudinal base portions including a pair of structural members extending outwardly from said transverse base member in generally longitudinal alignment; said structural members being each removably received by said transverse base member; and fastening means removably securing said pair of structural members to said transverse base member whereby said wheeled hosit may be readily disassembled for shipment.
Claim 2
Dependent Claim
207 words
A wheeled hoist having a base formed from a transverse base member, and a longitudinal base portion extending forwardly from said transverse base member; said base being supported by wheels, comprising: a post carried by said base and being inclined rearwardly toward said transverse base member; means supporting said post carried by said transverse base member on one end and tapering inwardly toward and being removably connected to said post on the other end; one of a pair of transverse structural section forming a part of said base having a surface at substantially a right sngle to said post; fastening means removably securing said post to said surface at substantially a right angle thereto to transmit an axial load in bearing thereon; a boom mounted to be raised and lowered carried adjacent an upper end of said post extending outwardly above and in alignment with said longitudinal base portion; said longitudinal base portions including a pair of structural members extending outwardly from said transverse base member in generally longitudinal alignment; said structural members being each removably received by said transverse base member; and fastening means removably securing said pair of structural members to said transverse base member whereby said wheeled hosit may be readily disassembled for shipment.
Claim 3
Dependent Claim
204 words
A wheeled hoist having a base formed from a transverse base member, and a longitudinal base portion extending forwardly from said transverse base member; said base being supported by wheels, comprising: a post carried by said base and being inclined rearwardly toward said transverse base portion member; means supporting said post carried by said base on one end and tapering inwardly toward and being removably connected to said post on the other end; said transverse base member including a pair of longitudinally spaced transverse structural sections; a pair of end frame members bridging said longitudinally spaced transverse structural sections and being integrally connected thereto forming a support frame; fastening means removably securing said post to said support frame; a boom mounted to be raised and lowered carried adjacent an upper end of said post extending outwardly above and in alignment with said longitudinal base portion; said longitudinal base portion including, a pair of structural members extending outwardly from said transverse base member in generally longitudinal alignment; said structural members being each removably received by a respective end frame member; and fastening means removably securing said pair of structural members to said transverse base member; whereby said wheeled hoist may be readily disassembled for shipment.
Claim 4
Dependent Claim
204 words
A wheeled hoist having a base formed from a transverse base member, and a longitudinal base portion extending forwardly from said transverse base member; said base being supported by wheels, comprising: a post carried by said base and being inclined rearwardly toward said transverse base portion member; means supporting said post carried by said base on one end and tapering inwardly toward and being removably connected to said post on the other end; said transverse base member including a pair of longitudinally spaced transverse structural sections; a pair of end frame members bridging said longitudinally spaced transverse structural sections and being integrally connected thereto forming a support frame; fastening means removably securing said post to said support frame; a boom mounted to be raised and lowered carried adjacent an upper end of said post extending outwardly above and in alignment with said longitudinal base portion; said longitudinal base portion including, a pair of structural members extending outwardly from said transverse base member in generally longitudinal alignment; said structural members being each removably received by a respective end frame member; and fastening means removably securing said pair of structural members to said transverse base member; whereby said wheeled hoist may be readily disassembled for shipment.
Claim 5
Dependent Claim
16 words
