Brake Power Unit

Application



Brake power units (for a luffing winch) are used on ship loaders to hold a boom in position and to stop them from falling. In older brake power units, the speed at which the brakes were applied took too long and could not handle the high ow of oil getting into the braking system.

Solution



Custom Fluidpower designed a tightly compact upgrade to the old brake power unit. This one, with safety features in mind, contains two large valves (one redundant), and a fail-safe brake. The upgrade allows presure to 50 bar then decay to 0 bar in 2-3 seconds.

Key Features



  • 5.5 kWh
  • 20 lmp (variable displacement pump)
  • 80L tank
  • >300 lmp return flows
  • Brakes come on in 0.2 seconds
