HydrauWinch 80 IG Immersion Guidance

HydrauWinch 80IG

A 80 mton immersion guidance winch. The HydrauWinch 80IG is driven by four high torque hydraulic motors through a pinion/gear transmission. Each of the hydraulic motors are equipped with a displacement shift and controlled by one hydraulic valve block. Three positions of the displacement shifts can be selected to obtain different torques and speeds. The hydraulic valve block ensures safe operation for the 4 hydraulic motors and brakes. The electronic controls are exclusive but can be provided.


  • Speed control: controlled acceleration and deceleration to the set cable speed, enabling even payout of the winches
  • Load control: Monitoring and regulating cable load and resulting disk load to prevent overloading of the structure.
  • Payout control: Highly precise cable payout for careful positioning of the tunnel element
  • Communication protocol: throughout the operation, all winch information can be transmitted to the survey system for visualisation and logging
