TECHNICAL FEATURES
• Welded steel frame in according to DIN 15435 (drum brakes) zinc
coated steel frame (disc brake)
•Epoxy resin painting (2 coatings) with RAL 5010 final color

•Asbestos free lining pads,glued to easy-to-replace plates (disc
brakes).
• Braking torque scale indicator
•Protection grade IP 56
OPERATION
• WC Drum and disc brake are nagative
•The braking force is obtained by means of a spring that, through
a suitablesystem of levers,transmits its amplified action to the
braking pads.
• An electrohydraulic or pneumatic thrustor makes an opposite
force to the spring, causing the pads open, therefore the brake to
release.
•The braking force of the linings against the drum can be modulated
by adjusting the spring.
• Braking torque changes depending on braking force modulation.
