drum brake / pneumatic / spring / emergency

Service brakes, safety brakes, emergency brakes welded steel structure in accordance with standards DIN 15435

APPLICATIONS
? Service brake
? Safety brake
? Emergency brake

ORIGINAL EQUIPMENT
? Welded steel structure according to DIN 15435 - epoxy resin painting (2 coatings) - RAL 3000 final colouring.
? Manganese phosphated pins.
? Self-lubricating bushes on main joints.
? Light alloy drums with asbestos free bonded linings
?Friction coefficient ?=0,42
? Braking torque scale indicator.

OPERATION
? The drum brakes WESTCAR type A are negative.
? The braking force is obtained by means of a spring that, through a suitable system 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 to 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.
