As time progresses, with our increasing integration especially in Europe and the World, Security has been gradually becoming increasingly important. Positive measures have been implemented in terms of job and staff security and health on the basis of both state and private organizations. Besides, manufacturers aim to expand equipment and machine lives by developing various products and applications related to machine and equipment safety as well as provide safety for staff working with the machine. Locking systems developed for the safety of moving cylinder equipment carrying loads can especially be used with bot hydraulic and pneumatic drive systems. For example, for a hydraulic press, locking mechanisms mounted on auxiliary cylinders pre-installed on press are immediately activated in case of a potential emergency in hydraulic power unit of the press or in hydraulic cylinders that move the top plate and hold the top plate and mold weights, thus they will protect the machine and the operator from damage.

Another advantage of the locking systems is the ability to safely lock the top plate along the stroke during maintenance.

Safety locking units are available in different capacities for loads with different weights. Most commons are from 1 ton to 85 tons for hydraulic driven ones, and from 1 ton to 22 tons for pneumatic driven ones. A single mechanism can be applied to the same system. Depending on the machine design, two or more mechanisms can be mounted and the load holding capability can be increased.
