Abstract
A concave personnel basket for an aerial work platform such as a boom lift is disclosed. The personnel basket is configured with a middle portion, facing away from the boom lift, that is recessed several feet towards the boom lift. The basket also has two opposite ends, also facing away from the boom lift, that protrude several feet outward relative to the middle portion. As a result, the personnel basket can partially envelop convex target structures such as cell towers and building corners. Personnel standing in the basket can thus access multiple sides of the target without needing to command the boom lift to reposition the basket. This improves work efficiency and safety.

A personnel basket for an aerial work platform comprising a boom lift, said basket comprising:
- a basket floor with a floor top, a bonded, symmetrical, polygonal floor bottom, and a bonded, symmetrical, polygonal floor perimeter with a plurality of floor sides, said floor bottom configured with a flat center portion of said floor bottom configured to attach to a boom lift arm on a boom lift side of said floor perimeter by a basket rotator and at least one support beam or bracket;
- said floor bottom further comprising at least two other diagonal sides facing towards said boom lift, and at least two sides facing away from said boom lift;
- said floor top configured with a substantially flat surface configured to allow at least one adult person to stand on said floor top while said floor bottom is attached to said boom lift, and lifted above the ground by said boom lift;
- said floor perimeter of said basket floor and said plurality of floor sides configured with at least an away facing middle portion and two away facing opposite ends;
- said away facing middle portion being flat and parallel to said flat center portion, and bonded to said two away facing opposite ends by the at least two other diagonal sides facing away from said boom lift;
- said floor perimeter further configured in a concave shape with said two away facing opposite ends disposed at least two feet further away from said boom lift side relative to said away facing middle portion;
- thus allowing said basket floor, and a person walking along said basket floor, to move freely throughout the platform and more closely approach multiple sides of a convex elevated work target of interest while said floor is lifted above the ground by said boom lift;
- said floor perimeter further configured with a guard rail raised at least three feet above said floor top.

- said floor top configured with a substantially flat surface configured to allow at least one adult person to stand on said floor top while said floor bottom is attached to said boom lift, and lifted above the ground by said boom lift;
- said floor perimeter of said basket floor and said plurality of floor sides configured with at least an away facing middle portion and two away facing opposite ends;
- said away facing middle portion being flat and parallel to said flat center portion, and bonded to said two away facing opposite ends by the at least two other diagonal sides facing away from said boom lift;
- said floor perimeter further configured in a concave shape with said two away facing opposite ends disposed at least two feet further away from said boom lift side relative to said away facing middle portion;
- thus allowing said basket floor, and a person walking along said basket floor, to move freely throughout the platform and to more closely approach multiple sides of a convex elevated work target of interest while said floor is lifted above the ground by said boom lift;
- said floor perimeter further configured with a guard rail raised at least three feet above said floor top;
- wherein said guard rail associated with a boom facing middle portion next to said boom lift side of said floor perimeter further comprises a support for a substantially rectangular boom lift control box;
- wherein a portion of said guard rail associated with said away facing middle portion further comprises a hinged gate and a latch configured to open and shut;
- said gate configured to swing inward when said latch is open, thus enabling personnel to enter and exit said basket;
- said gate configured to remain shut when said latch is shut, thus protecting personnel inside said basket from accidentally falling out of the basket;
- wherein said hinged gate is disposed opposite said boom lift side in said away facing middle portion.
