Abstract: A lifeline trolley (10) has a channel which fits over and runs along a fixed lifeline (12). A personal lifeline can be attached to the trolley, and the trolley has a brake (28) which is activated by a snatch loading on the personal lifeline to brake the trolley on the fixed lifeline.

Abstract: The present invention relates to a base plate assembly for use in lifting articles having a bore therethrough. The base plate assembly is formed having a base adapted to receive and support the article with its bore extending substantially normally from the base. An annular wall member upstands from the base plate and is adapted to locate in the bore. A load-bearing cross member extends substantially diametrically across the interior of the wall member and is provided with a securing device so that the cross member is positively secured to the wall member. The securing device is disengageable so that the cross member can be demounted from the wall member. A length of load-bearing sling material has one end adapted to be passed up the bore in the article to extend beyond the distal end of the bore and to provide a loop by which the base plate and the associated article can be lifted. The other end of the length of sling material is formed as a loop around the cross member for attaching to the base plate.
