riding in overturning buckets like that was common in the tunnelling industry into the early 1980s.... most contractors had a "man riding bucket" consisting of an overturning muck skip with the dodgers drilled for a bolt ( to stop them being opened ) into the 1980s... I first saw actual purpose-made man-rider skips around that time, painted white and with SWL marked in kg and no of persons, although they had been in use for long time in some quarters
