1. An anchorage device for attachment to an aerial lift where the aerial lift includes a boom and a bucket configured to hold a worker, the boom having a first boom anchorage point and a second boom anchorage point, the bucket having a boom side and a non-boom side, the boom being directly attached to the boom side of the bucket and the boom not being directly attached to the non-boom side of the bucket, the anchorage device comprising:
a base plate for coupling to the bucket of the aerial lift, the base plate being attached to the non-boom side of the bucket; a slide bar having a length between a first end and a second end, the first and second ends of the slide bar being coupled to the base plate; a first stanchion having a proximal end and a distal end; a second stanchion having a proximal end and a distal end, the proximal ends of the first and second stanchions being attached to the base plate, the first end of the slide bar being attached to the distal end of the first stanchion, and the second end of the slide bar being attached to the distal end of the second stanchion; a first supplementary anchorage point coupled to the base plate and configured for attaching to the first boom anchorage point using a first supplementary lanyard, the first supplementary anchorage point being attached to the first stanchion between the proximal and distal ends of the first stanchion; and a second supplementary anchorage point attached to the second stanchion between the proximal and distal ends of the second stanchion, the second supplementary anchorage point being configured for attaching to the second boom anchorage point using a second supplementary lanyard; wherein the slide bar allows a lanyard coupler attached to the slide bar to slide along the length of the slide bar between the distal end of the first stanchion at the first end of the slide bar and the distal end of the second stanchion at the second end of the slide bar, wherein if the base plate detaches from the bucket when the first supplementary lanyard is attached between the first supplementary anchorage point and the first boom anchorage point, the first supplementary lanyard restrains falling of the anchorage device; and if the base plate detaches from the bucket when the second supplementary lanyard is attached between the second supplementary anchorage point and the second boom anchorage point, the second supplementary lanyard restrains falling of the anchorage device. |
