摘要： A boom hoist is disclosed having top and bottom mast sections joined together midway of an upstanding mast at a swivel joint defined by mating flange faces where the top mast section rotates about a central core extending into each mast section. A boom arm is pivotally carried by the top mast section and a universal attachment base is carried by the bottom mast section having a tongue connection for connecting the hoist to a plurality of associated structures for hoist operation. Advantageously, a side mount assembly for mounting the hoist near a side of a vehicle, a three-point hitch mount assembly for mounting the hoist to a farm tractor, a fork lift mount assembly, a floor mount assembly, and a roller frame mount assembly are provided for the hoist.
