Rope Cutters

quicKutter

Kemp Propulsion Systems supply the quicKutter. The revolutionary quicKutter™ rope cutter system eliminates rope and line problems. The system has no moving parts to wear out, and is easy to install.

  • quicKutter™ cuts rope, line and twisted steel line.
  • Extremely competitively priced.
  • International Patent applied for.
  • Available in 3 sizes: Series 16 for shaft sizes 1″- 2″, Series 25 for Shaft sizes 2″- 4″ and Series 30 for Shaft sizes of 4″- 6″

Bearing Failure Due To Rope And Line Entanglement

Cause

  • Vessels operate in waterways where there is an increasing presence of rope and line.
  • Rope or line is entangled with the propeller and wraps around the shaft between the propeller and the bearing carrier
  • The tight coils of rope or line restrict the flow of fresh lubricating water to the lubrication zone between the bearing and the shaft
  • The tight coils of rope or line may melt due to friction and enter the bearing sealing off the flow of fresh lubricating water.

Consequences

  • Bearing burnout and propulsion system damage
  • Unscheduled down time = less operating time = less income
  • Increased frequency of repairs = increased operating costs = decreased profits.
  • Threat to the welfare of the crew.

Problem

  • Rapid failure of the bearing due to overheating.
  • Premature wear of the bearing due to overheating
  • Risk of severe damage to the propulsion system due to associated stress
  • Risk of severe damage to the propulsion system due to associated stress
  • Other types of cutters may reduce boat speed

Solution

  • Stop the rope or line from wrapping around the shaft between the propeller and the bearing carrier.
  • Ensure the rope or line is continually cut away to allow a continuous flow of lubricating
    water through the bearing.
  • Install the Quickwater quicKutter™ System (Patent Pending).

Benefits

  • Reduces the risk of propulsion failure
  • Cost effective – low capital cost for high savings
  • Increased bearing and shaft life = Reduced maintenance costs
  • Reduced down time = Increased income
  • Easily installed and fits all shaft sizes (Can be fitted to vessels with full keels)
  • Simple, robust and effective
  • Provides effective protection against rope and line
  • Blades can be easily replaced if required
  • Easily integrated with the Quickwater Sandstopper

How does the Quickwater quicKutter™ System Work?

The Quickwater spool is fixed to the propeller between the propeller and bearing carrier to prevent the rope or line from wrapping around the shaft. It provides a surface for the rope or line to wrap around to enable the quicKutter™ blades to continually cut the coils of rope or line as they form and are pressed against the quicKutter™ blades.

The quicKutter™ is fixed to the bearing carrier and protrudes out over the Quickwater spool surface ensuring that the clearance does not allow rope or line to pass under the blade and that rope or line is continually cut away to allow a continuous flow of water to exit from the bearing.
