Heavy Duty Anchor Drive Units

-- Steady & Reliable Manufacturer --

Introduction

Heavy Duty Anchor Drive Units are high-performance power transmission systems designed to generate the torque required for deploying and retrieving large anchors under extreme working conditions. They are primarily used on large commercial vessels, offshore ships, and marine platforms where conventional anchor drives are insufficient.

These units are engineered to operate reliably under high static and dynamic loads caused by vessel movement, seabed resistance, and environmental forces such as waves and wind. Their design emphasizes power, durability, and precise control to ensure safe anchor handling.

In offshore applications, heavy duty anchor drive units often form part of integrated anchoring and positioning systems, contributing directly to vessel stability and operational safety.

Specification

Maximum Output Torque Up to 10,000 Nm or higher, depending on design
Drive System Hydraulic motor combined with heavy-duty gearbox
Rated Duty Cycle Continuous heavy-duty operation
Control Interface Manual, remote, or integrated control system
Protection Level Offshore-grade sealing and corrosion protection

Application

Heavy duty anchor drive units are commonly used in demanding marine and offshore scenarios.

  • Large commercial vessels and tankers
  • Offshore drilling and support vessels
  • Anchor handling and construction ships
  • Floating platforms and special-purpose marine structures

Advantages

Designed for extreme conditions, heavy duty anchor drive units offer clear performance advantages.

  • Delivers extremely high torque for large anchors
  • Maintains stable output under shock and peak loads
  • Supports long operating cycles with minimal downtime
  • Improves overall safety during anchoring operations

Material and Structure

The housing is manufactured from high-strength alloy steel to withstand heavy mechanical loads and vibration. Internal gear systems are precision-machined and optimized for efficient torque transmission.

Advanced sealing and lubrication systems protect internal components from seawater ingress, ensuring long service life in offshore environments.
