Abstract
In access equipment of the type in which a working
platform or cage is carried at the upper end of a boom
assembly comprising a lower boom pivotally mounted on a
support structure and an upper boom pivotally connected to
the lower boom and in which the pivoting movements are
effected by drive means operated by hand levers, stop
members are provided associated with the hand levers and
the position of the stop members is so controlled in
accordance with the angle between the upper boom and the
horizontal as to prevent the hand levers being moved into or
remaining in operating positions which would increase the
angle beyond a predetermined value.
