Stacker crane safety brake system (SBS)
Our safety brake system (SBS) for stacker cranes consists of an SKP 50, 65 or 95 disc brake that acts directly on the stacker crane travel railhead. The brake and integrated Dellner hydraulic power pack (HPP) is mounted on a bracket designed to fit the crane’s structure. For warehouses where regular hydraulic oil isn’t allowed, the systems can as an option be supplied with food grade, freeze grade or food-freeze grade oil, instead of the standard mineral based oil.
Compared with hydraulic buffers, an emergency brake system has the following advantages.
- Cranes can be stopped anywhere in the aisle if speed exceeds a set limit or in an emergency, so they can work at higher speeds
- Retardation and mechanical forces acting on the cranes can be up to three times lower, which can extend crane life or allow a lighter crane to be used
- Less space is required because you don’t need the extra racking or other strengthening mechanisms to handle buffer shock after an emergency stop
- Running and maintenance costs can be reduced
