Parker-Origa has introduced a range of stop cylinders that provide damped braking and reliable holding of heavy conveyed loads.

Variants are available for horizontal and vertical installation, and the design facilitates change of the integrated shock absorber element, enabling the damping characteristics to be tailored to changing workpiece loads and speeds.

The stop cylinders have been developed to provide smooth deceleration characteristics to safeguard the workpiece.

The ability to lock the stop cylinders in their rearmost end position prevents the workpiece from rebounding.

The replaceable shock absorbers are selected according to the weight of the conveyed load and the speed of movement.

If the conveyed load is changed, the speed adjusted, or the mass of the workpiece to be stopped or altered, the shock absorber can be quickly changed, even in the installed condition.

By twisting the stop head the stop cylinder can change the direction of travel of the conveyed load.

If a change of operation is required, from ‘stop’ to’ free travel’ of the conveyed load, the rocker mechanism of the stop cylinder can be deactivated without the need for tools.

Different models in the range allow the workpiece to be stopped by a shock absorber and roller lever combination, roller lever alone, or piston rod.

With a maximum operating pressure of 10 bar, the stop cylinders can handle workpieces up to 1,700kg and conveyor speeds of up to 45m/min.

The stop cylinders are currently available in single-acting (with spring return) or double-acting versions.

As an option, position switches can be fitted for the rocker and the piston rod to provide positional feedback.
