Electric Torque Output Devices

-- Steady & Reliable Manufacturer --

Introduction

Electric Torque Output Devices are advanced marine and industrial equipment designed to deliver precise torque for deck machinery, winches, capstans, and pulling applications. These devices utilize high-efficiency electric motors combined with precision gearing to ensure smooth, controllable torque output in a variety of operational conditions.

Engineered for high reliability and continuous operation, these devices allow operators to adjust torque levels in real time, protecting lines, cables, and mechanical components from excessive stress. Their modular design enables integration with existing deck systems or automated control interfaces.

Electric Torque Output Devices are ideal for vessels, offshore platforms, tugboats, and marine construction projects. They provide energy-efficient torque delivery with minimal maintenance requirements, making them an essential component for modern marine and industrial operations.

Specification

Rated Torque 5 kNm to 500 kNm depending on model
Drive Type Electric motor with precision planetary or bevel gearbox
Control Mode Local manual, remote panel, or integrated bridge control
Speed Range Variable up to 20 rpm, adjustable for load conditions
Duty Cycle Continuous operation with overload protection
Efficiency Up to 95% mechanical and electrical efficiency
Environmental Protection IP65 rated housings, corrosion-resistant materials, marine-grade coatings
Line Compatibility Wire ropes, synthetic lines, chain cables

Application

Electric Torque Output Devices are widely used in marine and industrial operations:

  • Deck winches for mooring and anchoring large vessels
  • Pulling operations on offshore support vessels and FPSOs requiring precise torque control
  • Towing and salvage operations by tugboats and rescue vessels
  • Industrial lifting and hoisting applications for heavy loads
  • Marine construction projects for controlled cable and chain handling

Advantages

The benefits of electric torque output devices include:

  • Precise torque control for improved operational safety and reduced line stress
  • Energy-efficient operation with lower operational costs
  • Smooth, reliable performance under continuous load
  • Modular and compact design for flexible installation
  • Reduced maintenance compared to hydraulic systems

These features ensure longer service life, increased deck operation efficiency, and enhanced safety for personnel and equipment.

Material and Structure

The devices are built with high-strength steel or alloy housings to withstand torque and dynamic loads. Internal gears and shafts are precision-machined and heat-treated for durability.

Bearings, seals, and electrical components are marine-grade and corrosion-resistant, ensuring reliability in harsh offshore environments. Housings are protected with marine-grade paints or coatings for extended service life.

Installation Tips

To ensure optimal performance:

  • Mount the device on a solid, level surface with adequate reinforcement for torque reaction
  • Align the output shaft with the connected line or equipment to prevent misalignment stress
  • Verify electrical connections, voltage, and control interface compatibility
  • Perform low-load test runs to verify torque control, speed adjustment, and emergency stop functions
  • Inspect mounting bolts, housings, and electrical components periodically to maintain reliability

Comparison

Compared to hydraulic or pneumatic torque systems, electric torque output devices offer precise control, energy efficiency, and lower maintenance requirements. Electric drives provide smoother torque curves and are easier to integrate with automated control systems.

While hydraulic systems can handle ultra-high torque, electric devices excel in precision, responsiveness, and operational flexibility for modern deck machinery applications.
