  •  MECHANISM – free-floating when set and self-centering
    when released
  •  ACTUATION – spring set / hydraulic released, hydraulic set /
    spring released – spring compensated
  •  MOUNTING – foot-mount or side-mount, actuators either
  •  CONSTRUCTION – steel and ductile iron, or aluminum
    shoes, stainless steel pins standard
  •  CONFIGURATION – single or double actuator, offset to
    either side of brake disc
  •  LININGS – non-asbestos compositions to suit application
  •  DISCS – solid or ventilated, carbon or stainless steel, cast
    iron or non-ferrous
  •  OPTIONS – special alloys, coatings, controls and custom
  •  APPLICATIONS -hoists / winches, conveyers, drives,
    processing machines
  •  ENGINEERING -application and selection assistance

Direct Spring Acting Hydraulic Disc Brakes:

Direct Acting Caliper Brake Used for Drawworks

Direct Acting Caliper Brake Used for Drawworks

Fast acting, requiring little maintenance and almost no lubrication, accommodating several applications and can endure harsh operating environments.  Used successfully for many applications such as emergency braking systems for Container Cranes and Ladle Cranes, Drawworks, Conveyors, and Logging Mills.

Direct Spring Brake Features: 

  • Spring set, hydraulic pressure release
  •  Self-contained removable actuators
  •  Many spring stack options
  •  Stroke / wear adjustment
  •  Spring caging feature
  •  Hydraulic pressure isolated from disc
  •  Actuator manual release / retraction
  •  Fixed assemblies with opposing actuators
  •  Floating assemblies with low friction float bearings
  •  Floating assemblies with single or opposing actuators
  •  Narrow profile with actuators on one side
  •  Single and multiple actuator assemblies
  •  Optional bases for fixed and floating assemblies
  •  Optional release and wear proximity – switches
  • Flow through actuators – better oil filtering
