Metalforming Solutions The fastest Hydraulic Overload Protection System in the industry. Overview When an overload occurs, an oil-filled chamber trips, enacting AIDA’s patented oil escape system that delivers the fastest response in the industry (ten milliseconds), ensuring that your press is not stuck at BDC or damaged. This instantaneous reaction is only possible with the AIDA ball socket type HOLP system.

The HOLP can also be released at any time using AIDA’s "unstick" switch. This feature frees a slide "stuck" on bottom in a matter of seconds. Recovery time to reset the overload takes only seconds, so tool set up and down time is significantly reduced.

The HOLP system is easily adjustable from 110 down to 60 percent of press capacity to provide protection that matches the tool being used. The HOLP can be set to release when a tool gets too dull and help avoid production of bad parts.
