  • Tappet springs with guide pins for protection against shearing forces
  • Aluminium rotor with toothed intermediate ring: friction lining and tooth system with low rates of wear

Guaranteed performance data for the LongLife design

  • Guaranteed service life of brake mechanism: 10x106 repetitive cycles of operation 15x106 reversing cycles of operation
  • The brake warranty covers either a period of two years or the guaranteed number of cycles - whichever is reached first.
  • The scope of the warranty in the event of premature failure covers replacement of the brake, including a flat-rate replacement fee

Hand Release

The hand release is used to release the brake by hand and can be retrofitted. The hand release springs back to its base position automatically after operation. The hand release requires an additional air gap SHL in order to function; this is factory-set prior to delivery. Dimension SHL (see the mounting instructions) must be checked once the equipment has been mounted.


A flange can be used if no suitable counter friction face is available. The flange can also be fitted with a cover ring.

Friction Plate

A friction plate is available for sizes 06 up to and including 16. This should be used if the counter face is smooth and machined, but is not suitable as a friction surface. The plate can be combined with a cover ring.
