Magnetbau Schramme - Double and Single-acting Spreader Solenoids

Spreader solenoids are used almost only as actuation (releasing) magnets for brakes. Single-acting spreader solenoids are used almost only in moving stairways (escalators), or as replacement units for older elevators. Only double-acting spreader solenoids are allowed to be used in passenger elevators.


Single-acting and double-acting spreader

DC single-acting spreader solenoids are single-stroke linear solenoid systems designed for pressure-exerting force action. When hinge-suspended by the rear side, they are suitable for spreading, as required for releasing brakes.


DC double-acting spreader solenoids consist of two magnet systems that are combined in a housing and operate pressure-exerting in opposed direction to each other. They are suitable for spreading applications, e.g., for releasing brakes.


The following spreader solenoids are examples for brake magnets realized in series. Magnetbau Schramme developments are customer-specific. If you are searching for the right electromagnet, brake, spreader or double-acting spreader solenoid for your series project, simply contact us for the perfect solution. Our team will help you - guaranteed.

If you want more detail information about single-acting or double-acting spreader solenoids please contact us here.

Please note that we do not have „ex stock“ standard products, and can therefore only process inquiries for series.
