Abstract

Pivoted (11) platform (1) forms bridge between loading area (2) and lorry or van. Platform is raised by hydraulic cylinder (3,31) and secured against disengagement from vehicle by stops (4). When platform needs to be lowered to accommodate small van electromagnet disengages catch and spring retracts (4a) stops. Stops are automatically reset by chain and spring (9,10) when platform is raised.
