The components shown in the safety edge catalogue have heights up to 150 mm. Further, they are
generally equipped with one Haake contact chain only.
In certain applications, the power-operated devices have, due to their inertia, long stopping times
and thus also large stopping travels. Examples are big and heavy doors (hangar doors),
automatically-guided vehicles (AGV), theatre stages etc.
In these cases, the up to 150 mm high safety edges mentioned above will not be sufficient.
Here so-called bumpers are used. Their dimensions as well as the positions and number of the
contact chains are specially selected and manufactured for the intended application.
Bumpers are protection devices for large over-travels. They are equipped with a rubber-foam
cushion with suitable surface finish and reinforced if necessary. Colours may also be applied.
Hazardous machines and systems are frequently equipped with safety elements (safety doors) with a locking mechanism to protect the operator. Their function is:
To protect against risks at shearing and crushing edges, safety sensitive edges are employed.
Applications such as machine guards, lifting tables, theatre stages ...
To protect persons against risks of this kind, pressure sensitive safety mats are employed. At devices such as machines, machining centres, presses, robot cells, ...
Valve interlocks are used everywhere where a sequence of valves helps protect personnel and machinery.
These are mainly:
- offshore applications,
- chemical plants ...
