Overview:
The advanced rod lock cylinder technology is presented in this paper as a cost-effective solution which can address industrial safety issues in pneumatic applications. Rod lock cylinder is a piston-operated clamp used to hold a load in position during emergency stop (E-stop) conditions or when an air supply might be accidentally disconnected from a system. Detailing the components and functioning of rod lock cylinders, the paper states their wide range of applications. It describes the benefits of rod lock cylinders as plant safety solutions in comparison with other safety device systems. Different ways in which rod lock cylinders can be retrofitted and installed to suit specific safety requirements are explained, focusing on the performance characteristics of Parker 3MAJ/4MAJ series NFPA (National Fluid Power Association) rated rod lock cylinders.
