Abstract
Lift assemblies and methods of operating same. A lift assembly for a vehicle includes at least one support member having a longitudinal axis lying on a plane and which is configured for attachment to the vehicle. A mast having a proximal end, a distal end, and a mast axis is pivotably coupled with the at least one support member at the mast proximal end. At least one gear arrangement is coupled between the at least one support member and the mast proximal end. The mast is pivotable relative to the at least one support member about an axis parallel with the plane through an angular displacement greater than 90 degrees. A boom is pivotably coupled with the mast proximate the mast distal end, and a first lift line is coupled with the boom.

A lift assembly for a vehicle, the lift assembly comprising:
- at least one support member, the support member having a longitudinal axis lying on a plane, the at least one support member configured for attachment to the vehicle;
- a mast having a proximal end and a distal end, the mast having a mast axis, wherein the mast is pivotably coupled with the at least one support member at the mast proximal end;
- at least one gear arrangement coupled between the at least one support member and the mast proximal end;
- wherein the mast is pivotable relative to the at least one support member about an axis parallel with the plane through an angular displacement greater than 90 degrees;
- a boom pivotably coupled with the mast proximate the mast distal end;
- and
- a first lift line coupled with the boom.
