Bollard Pull Tests - Tug Boats / Drag Force Measurement

Bollard pull trials are conducted in order to determine the static pull that a tug is able to employ in operating conditions. Unlike ground vehicles, the statement of installed horsepower is not sufficient to understand how strong a tug is - this is because other factors, like transmission losses, propulsion type, propulsion system efficiency, have an influence as well.

Dynamometers are used for force and load control, including drag force measurement, for example: Bollard pull test, drag force measurement of rescue vehicles, plows, etc.

Ron dynamometers are especially suitable for force measuring due to these following features:

  • Small and portable

  • Remote indicator

  • RS-232

  • Additional displays

  • Data logger

  • 2000h battery life

  • Perpendicular design between shackle holes

  • Aerospace quality steel

  • Fatigue rated load cells

  • Set points

  • 40 years of experience
