1.1. Rotor brakes

1.1.2 Active brakes

These brakes are called active or positive brakes because they need pressure in order to brake. This name differentiates them from the failsafe or passive brakes.
Active brakes do not use springs.
Active brakes always have an E in the model name (NHCE, NHCEN, HE), which identifies them as active brakes.
Its main characteristics are:

  • Active brakes with self-aligning system, which allows them to adjust the position of the brake with regard to the disc
  • Hydraulic braking and spring released

NHCE 900
Its main characteristics are:

  • Clamping force up to 60.000 N, maximum pressure of 100 bar
  • Piston diameter 90 mm
  • Positive brake
  • Hydraulically applied
  • Self-aligning
  • Spring released

NHCE 900 Active brakes
NHCEN 900
Its main characteristics are:

  • Clamping force up to 57.000 N, maximum pressure of 130 bar
  • Piston diameter 75 mm
  • Positive brake
  • Hydraulically applied
  • Self-aligning
  • Spring released

NHCEN 900 Active brakes
NHCEN 120
Its main characteristics are:

  • Clamping force up to 150.000 N, maximum pressure of 135 bar
  • Piston diameter 120 mm
  • Positive brake
  • Hydraulically applied
  • Self-aligning
  • Spring released

NHCEN 120 Active brakes
NHCE 1400
Its main characteristics are:

  • Clamping force up to 150.000 N, maximum pressure of 160 bar
  • iston diameter 110 mm
  • Positive brake
  • Hydraulically applied
  • Self-aligning
  • Spring released

NHCE 1400 Active brakes

In the HE Series of active brakes, the name of the brake indicates the number of pistons and their diameter (HE-1-75: 1 x 75 mm diameter piston).
HE – 1-75
Its main characteristics are:

  • Clamping force up to 70.000 N and maximum pressure up to 160 bar
  • One 75 mm piston
  • Positive brake
  • Hydraulically applied
  • Spring released

HE 1 -75 Active brakes
HE – 2-90
Its main characteristics are:

  • Clamping force up to 200.000 N and maximum pressure up to 250 bar
  • Two 90 mm pistons
  • Positive brake
  • Hydraulically applied
  • Spring released

HE 2 - 90 Active brakes
HE-3-120
Its main characteristics are:

  • Clamping force up to 610.000 N and maximum pressure up to 180 bar
  • Three 120 mm pistons
  • Positive brake
  • Hydraulically applied

HE 3 -120 Active brakes
OPTIONS
Apart from the already mentioned brake-specific options, there are some common options valid for all brakes. These are the following:

  • Rotor brake lining
    • Antec offers 3 options regarding the composition of the lining:
    • Organic lining – up to 300 ºC
    • Semi-metallic lining – up to 500 ºC
    • Sintermetal lining – up to 900 ºC
  • Lining wear detector
    • Function:
    • On/off Indicator (brake on / brake off)
    • Lining wear indicator
  • Types of lining wear detectors:
    • Inductive
    • Mechanical
