Abstract
A self locking basket assembly has a basket extending from a base platform, and a gate system for releaseably securing a worker within the cage. The gate system includes a gate operatively mounted on a pivotable locking mechanism. The locking mechanism is opened by moving the gate in a rearward direction at an angle to a plane defined by the base platform and thereafter pivoting the gate about a hinge mechanism to an open position.
Claims18
A self locking basket assembly (16) for a personnel lift comprising a base platform (102), and
- a gate system (100) for releaseably securing a worker within the basket assembly, the gate system (100) including a gate (200) operatively mounted on a pivotable self locking mechanism (180),
- the locking mechanism (180) including a hinge pin (188), a locking member (190) coaxially positioned around at least a section of the hinge pin (188), and a pivoting member (210) coaxially positioned on the hinge pin (188),
- the locking member (190) including a locking member notch (194) which is in mating engagement with a first gate notch (218) on the pivoting member (210) when the gate (200) is in a closed position,
- whereby the pivoting member (210) is capable of axially and circumferentially pivoting on an axis that is on an angle to both the horizontal and vertical along the pivot pin (188), and whereby the locking member (190) is disengaged when a vertical and horizontal force is applied to the pivoting member (210).

A personnel lift (10) comprising
- a base (12),
- a lift assembly (14) attached to the base (12) and capable of extending along a vertical axis and having an upper end,
- an basket assembly (16) extending from the base platform (102), and a gate system (100) for releaseably securing a worker within the basket assembly,
- the gate system (100) including a gate (200) operatively mounted on a pivotable locking mechanism, the locking mechanism (180), the locking mechanism (180) including a hinge pin (188), a locking member (190) coaxially positioned around at least a section of the hinge pin (188), and a pivoting member (210) coaxially positioned on the hinge pin (188),
- the locking member (190) including a locking member notch (194) which is in mating engagement with a first gate notch (218) on the pivoting member (210) when the gate (200) is in a closed position,
- whereby the pivoting member (210) is capable of axially and circumferentially pivoting on an axis that is on an angle to both the horizontal and vertical along the pivot pin (188), and whereby the locking member (190) is disengaged when a vertical and horizontal force is applied to the pivoting member (210).
