Sautter Lift Components’ SG Series provides a high-quality range of small, compact safety gears. Ideal for narrow shafts and new installation, they allow optimum use of space in the lift car, requiring only 19.5mm (with 4mm clearance) between the guide rail head and the safety gear frame.

The SG1D-1 safety gear provides catch downwards performance only and is often used for new catch frames, when catch upwards is covered by a brake on the lift drive.

SG2D-1, Version 1

SG Series Safety Gear

The braking force for catching downwards and upwards can be set continuously and independently with variant 1.

SG2D-1, Variant 2

SG Series Safety Gear

Variant 2 of the SG2D-1 is more compact. The ratio for the braking forces below / above is fixed.

Advantages of the SG Safety Gears Series

  •  Small, compact design
    – 140mm x 146mm x 49.5mm for the SG1D-1
    – 200mm x 164mm x 56.5mm for the SG2D-1
  • High catch load combined with high speeds
  • Minimum space required between guide rail head and frame attachment: 19.5 mm (4 mm air)
  • Uniform deceleration due to long spring travel of the disk springs
  • Flexible use in systems with internal and external guide rails (MRL, backpack)
  • Low forces for releasing the car from the catch
  • A wide range of options for triggering the safety gear enables optimum synchronization, matched to different car designs
  • Prevention of unintentional release by separate securing of the catch roller
  • Safety gear is type-tested without release, this allows flexible installation
