The Flipper Arm Actuator SB18 is an alternative to the standard flipper arm gearbox. The Flipper Arm Actuator SB18 comes with a higher torque which makes placement on containers much easier. The actuator can be easily mounted on spreaders and is suitable for the six-flipper and four-flipper configurations. It is available both as an option for new spreaders, or as an upgrade on spreaders already in operation (additional mechanical modifications are needed to retrofit bases designed for smaller gearboxes on mobile harbour crane spreaders).

Benefits of the upgrade

  • Simple, rounded and robust design.
  • Assembly fits on the existing footprint.
  • Fewer operating parts, with less failure points.
  • Comes with a built-in cross-port relief valve.
  • The shaft ends increases force and extends lifetime.
  • Does not require lubrication.
