Electric tugger winch, line pull 12 kN (Technical supply specification)


1. General Data (Operating Conditions)

The tugger winch operates reliably under the following conditions:

  • Sea water temperature: −2 °C to +27 °C
  • Ambient air humidity: 60%–85%
  • Continuous vessel heel (either side): up to 5°
  • Continuous vessel trim (bow or stern): up to 2°

Stowed conditions:

  • Vessel heel (either side): up to 30°
  • Vessel trim (bow or stern): up to 6°

2. Purpose

The tugger winch is designed to handle and secure marine equipment components during vessel operations.

About

Application of Tugger Winches in Marine Systems

The tugger winch is integrated into marine lifting and auxiliary systems to stabilize and secure equipment components during operation. It provides controlled wire rope tension and is utilized when precise positioning of the boom or load is required without engaging the main hoist mechanism. These winches are critical for maintaining lifting system stability and mitigating dynamic loads.

Functional Role in Lifting Equipment Operation

The tugger winch operates in conjunction with cargo winches and luffing mechanisms to handle auxiliary loads. This ensures even load distribution and enhances overall system controllability during cargo handling or installation operations. The application of tugger winches is highly critical for over-the-side operations and within confined spaces.

Control and Integration with Other Mechanisms

Modern tugger winches integrate into the vessel equipment control system and can be operated from various control stations. This enhances operational convenience and allows the operator to control the process from an optimal vantage point. Independent control of each tugger winch ensures precise adjustment and increases operational safety.

Production and Design Customization

The design of these mechanisms incorporates classification society requirements and marine operation conditions. The tugger winch must be adapted to the specific vessel design and operational requirements. Izhora Hydrosystems LLC manufactures marine tugger winches, delivering solutions compliant with industry standards and customer specifications.
