MD3 Series

Category:

APPLICATIONS

  • Service brake
  • Safety brake
  • Emergency brake

ORIGINAL EQUIPMENT

  • Zinc coated steel structure - epoxy resin painting - RAL 3000 final colouring.
  • Stainless steel pins, self lubricating bushes on main joints
  • Asbestos free linings, bonded to easy-to-replace plates.
  • Friction coefficient µ =0,4
  • Braking torque scale indicator

OPERATION

  • The disc brake MATEC MD are negative brakes (spring loaded).
  • 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, where the linings are fitted.
  • An electro-hydraulic or pneumatic thrustor makes an apposite force to the spring load, causing the pads to open, therefore the brake to release.
  • The braking force given by the linings against the disk can be modulated by adjusting the spring. (see standard features).
  • 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
  • Brake manual opening lever LSM.

THRUSTOR TYPES

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