Abstract
A line guidance device (40) is provided for use with a confined space entry/retrieval hoist and fall protection anchorage system (10) and includes a line guide (46) that guides a line from an extend/retract line device (22) past another extend/retract line device (20) with both devices (20, 22) mounted on a backside (24) of a mast (12) of the system (10).
Claims18
A confined space hoist and fall protection anchorage system comprising:
- a post comprising a first side, a second side, a proximal end, and a distal end, the post oriented along a first axis;
- a line guidance device releasably coupled to the post at a first position and oriented away from the confined space, the line guidance device comprising a first flange and a second flange, the first flange and the second flange coupled perpendicularly a distance apart on a mounting plate, a pulley mounted between the first flange and the second flange and configured to rotate about a second axis perpendicular to the first axis;
- a first extend/retract line device supported on the mounting plate;
- and
- a second extend/retract line device removably coupled on the first side to the post at a second position proximal to the first position.

A confined space hoist and fall protection anchorage system comprising:
- a first post positioned adjacent to a confined space, the first post oriented along a vertical axis and having a first side oriented away from the confined space;
- a second post comprising one or more pulleys at a proximal end of the second post and one or more other pulleys at a distal end of the second post, the second post pivotably coupled to the first post via one or more brackets and a spar coupled to the first post and the second post, the spar having an adjustable longitudinal length such that, as the spar is extended and retracted, the second post is pivoted at a proximal end about the first post;
- an extend/retract line device removably coupled to the on the first side to the first post at a first position, the extend/retract line device comprising a line guidance device, the line guidance device being releasably coupled to the first post at a first position and oriented away from the confined space, the line guidance device comprising a first flange spaced a distance apart from, and oriented perpendicular to, a second flange, the first flange and the second flange being supported on a mounting bracket, the line guidance device further comprising a pulley mounted between the first flange and the second flange, the pulley configured to rotate about a second axis perpendicular to the first axis;
- and
- a second extend/retract line device removably coupled on the first side to the first post at a second position proximal the first position.

- a winch coupled to the mounting plate of the line guidance device, the winch configured to extend and retract a winch cable coupled to a harness worn by a worker suspended by the system;
- and
- a self-retracting lifeline device removably coupled to the post at a second position proximal to the first position and oriented away from the confined space, the self-retracting lifeline device configured to extend and retract a lifeline extending from the self-retracting lifeline device, about the pulley of the line guidance device, and coupled to the harness worn by the worker suspended by the system.
