SGB 01-02-03-05: Unidirectional progressive safety gears for low and medium speed.

Progressive scalable safety gear applicable for a wide range of loads.
Superb solution for car but also counterweight installation due to reduced width dimensions. Many modernization packages available. Available with compliance for many global lift norms and directives.

  • Safety gear acting in downward direction
  • Braking power is generated by expanding the C-profiled safety gear block
  • Wide application range (also Duplex arrangement available)
  • Different connections (top or bottom) from actuating mechanism to gripping wedges available
  • Various options like safety gear housing, synchronization linkage or governor rope connection for maximum flexibility
