Abstract

In a fluid-operated ram a piston member is reciprocable within a casing and divides the casing into two chambers. One of the chambers is arranged to be connected to a source of driving fluid while the other is arranged to be evacuated whereas the piston member is held by a quick-release mechanism, e.g. a mechanical bolt or an electromagnet arranged to co-operate with part of the piston member.
