Winches and Unreelers for Suspension Bridge Construction in South Korea

1. Project Overview

Zhifang has completed the delivery of a batch of friction winches and unreeler supporting equipment to South Korean. The machinery is specially customized for local suspension bridge construction projects, marking another milestone of the company’s overseas infrastructure equipment export business.

2. Equipment Configuration

• Total set quantity: 4 complete sets, 8 main machines in total

• Core equipment: JKM-22T friction winches & JTF-5T unreelers

• Supporting components: control cabinets, hydraulic power units, reducers, sensors, ABB motors, inverters and a full range of spare mechanical & electrical parts

3. Multi-mode Synchronous Operation Advantages

The integrated system supports flexible switching of multiple operation modes to adapt to diverse suspension bridge construction working conditions:

1. Independent operation: Each single machine can run separately for scattered small-scale construction tasks

2. Single-set synchronous operation: One set of winch + unreeler operates synchronously for basic cable laying work

3. Two-set linkage operation: Double sets run in coordinated linkage to improve construction efficiency for medium-scale main cable erection

4. Four-set full linkage operation: All four sets operate synchronously as a whole to meet large-scale, long-distance main cable traction demands of super-large suspension bridges

4. Product Technical Highlights

1. High load capacity: Designed for heavy-duty, long-distance continuous traction required by suspension bridge main cable construction

2. Precise tension control: Matching winches and unreelers deliver stable tension output to avoid construction safety hazards

3. Complete supporting system: Equipped with standardized control panels, drive systems and comprehensive spare parts to guarantee on-site continuous construction

4. Stable adaptability: Optimized structure to fit complex outdoor construction environments of bridge engineering

5. Significance of This Export

1. Market expansion: This batch of customized bridge construction equipment officially enters the South Korean infrastructure market, proving Zhifang Machinery’s international product competitiveness

2. Industrial cooperation: Promotes technical exchange between China and South Korea in the field of suspension bridge special engineering machinery

3. Brand development: Validates the recognition of Zhifang’s independent R&D technology and product quality by overseas engineering contractors

4. Future layout: Lays a solid foundation for the enterprise to further explore global overseas bridge infrastructure markets

6. Enterprise Outlook

Henan Zhifang Machinery will keep focusing on the R&D and upgrading of special bridge construction equipment. The company will continuously optimize multi-scenario linkage control solutions for suspension bridge construction machinery, supply safer, more efficient and more reliable engineering equipment for global infrastructure projects, and deepen international cooperation in the infrastructure manufacturing industry.
