TN Series – Integrated Ship Loading Spout

Product Overview

The TN series loading spout is developed for large bulk terminals and ship loading systems where durability, installation efficiency, and long travel stability are critical. Unlike traditional separated winch arrangements, the TN series integrates the lifting system directly with the loading spout structure. This integrated design reduces installation complexity, minimizes structural interfaces, and improves overall system reliability.

With its heavy-duty straight inner tube construction, modular maintenance design, and automation options, the TN series provides a practical solution for high-capacity bulk loading operations.

Advantages & Features

The TN series combines heavy-duty mechanical design with practical engineering features developed for large bulk loading projects. These advantages focus on structural durability, operational safety, ease of maintenance, and adaptability to demanding bulk material handling environments.

Heavy-Duty Long Travel Winch System

The TN loading spout is designed for heavy-duty ship loading and large stockpile applications requiring extended travel ranges and high structural strength. With total lengths up to 30 meters and travel up to 25 meters, the TN series is engineered for demanding bulk handling environments.

To support the higher loads associated with long travel and large capacity operation, the TN series uses a planetary gearbox drive system. Compared with conventional industrial gearboxes, planetary gear units provide higher torque density with lower weight, allowing a more compact and efficient lifting arrangement. This design ensures stable movement and reliable operation under heavy-duty conditions.

The integrated winch and spout design reduces on-site installation work and simplifies equipment installation, which is especially beneficial for large ship loading projects.

Heavy-Duty Inner Tube and Guiding System

The TN series adopts a straight inner tube design specifically developed for heavy-duty applications. This structure provides improved strength and durability compared with standard designs and is suitable for high-capacity bulk material handling.

Inner tube sections are connected using split clamping flanges . This modular design allows individual tube sections to be removed and replaced more easily, significantly improving maintenance efficiency.

UHMW polyethylene guide rings are installed between tube sections to prevent direct steel contact. The wear-resistant and self-lubricating properties of UHMW material reduce friction during extension and retraction, ensuring smooth movement and preventing sticking during long travel operation.

Heavy-Duty Inner Tube and Guiding System

Advanced Dust Sealing System

The TN loading spout features a double rubber skirt designed to maintain close contact with the material pile or ship hatch during loading operations, helping to minimize dust emissions. The outer dust sleeve is available in polyester, nylon, Hypalon, and rubber materials to match different environmental conditions.

The reinforced sleeve construction ensures durability and reliable sealing performance for large bulk material loading systems, particularly in outdoor and port environments.

Smart Automation and Safety Control

The TN loading spout integrates automation and safety features suitable for large bulk handling systems. Adjustable upper and lower limit switches and slack rope detection protect the lifting mechanism from abnormal operation.

Project-Based Custom Engineering

Each TN loading spout is engineered according to project-specific requirements for ship loading or large stockyard applications. Configurable items include inlet arrangements, discharge configurations, dust extraction interfaces, lifting arrangements, and control systems.

This flexibility allows the TN series to integrate smoothly into ship loaders, conveyor systems, and bulk terminals. Our engineering approach focuses on providing reliable solutions based on real operating conditions.

Long Service Life Construction

Critical components are manufactured using precision machining processes to ensure dimensional accuracy and stable operation. Protective surface treatments such as galvanizing and industrial coating systems provide corrosion resistance suitable for marine and outdoor environments.

Structural components are designed for continuous heavy industrial duty while minimizing maintenance requirements. These design features help extend equipment service life and ensure dependable performance in demanding applications.

Optional Features

Optional configurations allow the equipment to be adapted to specific process requirements and operating conditions, improving reliability, durability and operational performance.

Pivoting Inlet Hopper

The TN series can be equipped with a pivoting inlet hopper designed for conveyors with luffing movement. The hopper consists of an upper fixed section and a lower pivoting section connected by hinge pins. This allows the loading spout to remain vertical regardless of conveyor angle, improving operational stability and reducing structural stress.

Rotary Trimming Spout

The TN series can be equipped with a rotary trimming spout consisting of a slewing bearing, drive unit, and rotating distributor head. This system enables 360° material distribution, allowing material to reach deeper and side areas of the ship hold, improving hold utilization and reducing ship loader repositioning frequency.
