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 µ=0,42
• Braking torque scale indicator.

OPERATION
• The drum brakes MATEC 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.

OPTIONALS
• Automatic wear compensation (RG)
• Linings max wear indicator (fitted on rod) (FCU)
• Open brake indicator, either fitted on thrustor or on spring set (to be specified) )FCA)
• Larger drum (50% wider) (L)
• Stainless steel pins (INOX)

THRUSTOR TYPES

• MATEC type "M" electrohydraulic
• EMG type "ELDRO" electrohydraulic
• EMG type "ELTMA" electrohydraulic
• Pneumatic (upon request)
