Parker has introduced its P1D-H rod lock pneumatic cylinders for applications where safety is critical.
P1D-H cylinders have been purposely designed to hold loads safely in position even when there is an unexpected failure in the compressed air supply.
With this special functionality, the P1D-H represents an essential safety component in static applications that require extra safety for the protection of both objects and workers.
Available in bore sizes from 32 to 125mm, the P1D-H range offers a separate rod lock unit flange mounted to the front end cover of the cylinder. The impressive locking force is provided by the cartridge (through which the piston rod passes), which is mounted transversally in the rod lock unit. When there is no signal pressure, the force from the internal springs pushes the ‘over-the-centre’ mechanism to lock the piston rod using jaw clamps.
