Fluidically actuatable failsafe disk brake system and lifting device comprising said system

A fluidically actuatable disk brake system comprising:

• a plurality of brake cylinder pairs each comprising brake cylinders arranged on both sides of a brake disk in at least one brake caliper,
• wherein,
• each of the brake cylinders comprise a brake piston and a spring arrangement, the spring arrangement being configured to apply a spring force toward the brake disk,
• a first fluid connection and a second fluid connection are provided on each of the brake cylinders, the first fluid connection and the second fluid connection being configured to supply a fluid to the brake cylinder so that a force which counteracts the spring force can be applied to the brake piston to reduce a braking force exerted by the spring force,
• a 2/2-way valve is assigned either to the first fluid connection or to the second fluid connections of a first brake cylinder of a first brake cylinder pair,
• a 2/2-way valve is assigned either to the first fluid connection or to the second fluid connections of a second brake cylinder of the first brake cylinder pair,
• if the first fluid connection of the first brake cylinder of the first brake cylinder pair is assigned to the 2/2-way valve, the second fluid connection of the first brake cylinder of the first brake cylinder pair is fluidically connected to the first fluid connection of the second brake cylinder of the first brake cylinder pair, and
• if the second fluid connection of the first brake cylinder of the first brake cylinder pair is assigned to the 2/2-way valve, the first fluid connection of the first brake cylinder of the first brake cylinder pair is fluidically connected to the second fluid connection of the second brake cylinder of the first brake cylinder pair.
