Abstract

The bollard comprises an outer bollard element 3 comprising a bore, an inner bollard element 5, at least partly located within the bore and movable between retracted and extended states, at least one urging element 19 arranged to exert an force on the inner bollard to urge it towards an extended state, and a lifting apparatus 13,14 coupled to the inner bollard element and operable to exert a force sufficient to lift the inner bollard to the extended state when also subject to the urging force, with a coupling device decouplably coupling the urging element and lifting apparatus together. The inner bollard element preferably includes a bore within which the urging element and lifting apparatus are at least partially located. The lifting mechanism may comprises a lead screw and a nut or a pneumatic, hydraulic or electro-magnetic device. Also claimed is a kit of parts for a bollard.
