Anchorage devices for an aerial lift that can include a base plate and a slide bar coupled to the base plate. The aerial device can include a bucket, and the base plate can be coupled to the inside or outside of the bucket. Supplementary anchorage points of the anchorage device can be attached to the lift using lanyards. The slide bar can be attached to the base plate using stanchions. A removable anchorage device can include inner and outer mounting bars, bucket engaging brackets coupling the mounting bars, and a slide bar; where the bucket engaging brackets fit over the bucket for attachment to and detachment from the bucket. The removable anchorage device can include supplementary anchorage points for attaching to the lift using lanyards. One of the mounting bars can be hollow and a supplementary lanyard attached to the lift can pass through the hollow mounting bar.

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; anda 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. 2. The anchorage device of claim 1, wherein the slide bar is U-shaped. 3. The anchorage device of claim 1, wherein the slide bar is coated with an insulating material. 4. The anchorage device of claim 1, wherein the base plate is coupled to the outside of the bucket. 5. The anchorage device of claim 1, wherein the base plate is coupled to the inside of the bucket. 6. The anchorage device of claim 1, wherein the base plate is coupled to the bucket using an adhesive. 7. The anchorage device of claim 1, further comprising a mounting plate, the mounting plate being attached to the bucket, the base plate being attached to the mounting plate. 8. The anchorage device of claim 7, wherein the mounting plate is attached to the bucket using an adhesive. 9. The anchorage device of claim 8, wherein the base plate is attached to the mounting plate using bolts.
