Safety shoe

Product catalog summary

Product Overview: The safety shoe by Mayser GmbH & Co. KG is designed as collision protection for level control on various platforms such as passenger, baggage, catering, and maintenance platforms. It is robustly built for rough environments and offers excellent water resistance, functioning effectively even with a water level of up to 10 mm.

Specifications: The safety shoe features switches that can be configured as normally closed (NC) or normally open (NO) with force-guided contacts, ensuring a single-fault-safe system according to ISO 13849-1 up to category 3 PL d. The NC switches open upon actuation, while the NO switches close.

Applications: It is suitable for areas where mobile platforms might contact objects, such as around air traffic (e.g., passenger stairs, carousels).

Operation: When pressure is applied, the safety shoe triggers actuation, sending a command to the control system to adjust the platform's position.

Areas of application The safety shoe is designed as collision protection for the level control of passenger, baggage, catering and maintenance platforms. Pressure on the surface activates the interior switches. Its especially rugged installation makes it perfectly suitable for use in a rough environment and provides excellent water resistance on the surface. The function of the safety shoe is guaranteed even in wet conditions, with a water level of up to 10 mm in the position of use. Concept Switches are installed in the safety shoe as normally closed contact (NC) or normally open contact (NO)...

Operation The lifting platform is moved to the body of the airplane and the safety shoe is positioned between movable platform and object. The loading lowers the airplane which would make it collide with the lifting platform. The safety shoe helps detect this. Pressure is applied on the safety shoe during the pressing in. This triggers actuation and the control of the lifting platform receives the command to lower itself until the safety shoe is relieved again. Other versions (also with monitoring resistor) available on request. Subject to technical modifications.

Maintenance and cleaning The sensors are virtually maintenance-free. Regular inspection Depending on the load, the sensors are to be tested at regular intervals (at least monthly) • for correct functioning: by activation or by applying the relevant test sample. • for damage: by visual checking. Cleaning If necessary, clean the sensor with a mild cleaning agent. Technical data 4/4 Safety shoe www.mayser.com
