The RTG Crane Spreader is the lifting device installed beneath a Rubber-Tyred Gantry (RTG) crane trolley. It is used for container lifting, transfer, stacking, loading, and unloading operations. By connecting to the container corner castings through a twistlock system, the spreader provides a secure connection during handling in ports, container terminals, and inland container yards.
RTG crane spreaders are classified by their structure and operating functions. Common options include fixed, telescopic, rotating, and automatic spreaders.
A fixed RTG spreader has a fixed frame length and is designed for single-size container handling. The structure is simple and mainly used in dedicated or stable operating conditions.
Applications: used in facilities handling a single container size or specialized lifting operations.
A telescopic RTG spreader uses a hydraulic or electric extension system to adjust its frame length for different ISO container sizes. It is the most common type in container terminals.
Applications: Suitable for ports, inland container depots, rail terminals, and logistics yards handling mixed container sizes.
A rotating RTG spreader is equipped with a controlled rotation function to assist container alignment during loading and unloading. It is used where container positioning is not consistent.
Applications: Used in container yards where precise container positioning is required or where containers may not be perfectly aligned.
An automatic RTG spreader integrates sensors and control systems for locking, positioning, and operation feedback. It is used in semi-automated and automated container terminals.
Applications:Suitable for high-throughput container terminals, semi-automated facilities, and automated port operations.

The gantry crane is a lifting equipment widely used across various industries, construction sites, ports, warehouses, and other fields. Its unique structure and powerful load-bearing capacity make it ideal for modern heavy-duty material handling. The “gantry” structure design allows the crane to move freely within a space, covering a large working area. So, what makes gantry cranes special? What are their types, parameters, control methods, applications, and working principles? How do they differ from bridge cranes? Let’s explore together. Types of Gantry Cranes Based on design, application, and operating environment, gantry cranes are typically categorized into the following types: Single-Girder Gantry Crane Single-girder gantry cranes are widely used across industrial sectors, warehouses, ports, and workshops. Featuring a single-girder support lifting mechanism, they traverse via side columns and bottom rails. With their simple structure, user-friendly operation, and moderate lifting capacity, they are ideal for handling light to medium loads. Capable of spanning large distances freely, single-girder gantry cranes are suitable for heavy material handling and lifting operations. Double Girder Gantry Crane Compared to single-girder gantry cranes, double-girder gantry cranes offer greater…
In ports, logistics parks, and industrial material handling, Portal Cranes and Gantry Cranes are two common and core loading/unloading equipment types. They differ in structural design, performance characteristics, operating methods, application scenarios, and investment costs. This article provides a comprehensive analysis of Portal Crane vs Gantry Crane and guides you in making the right selection. Structural Design Comparison The structural differences between Portal Cranes and Gantry Cranes primarily manifest in load-bearing methods, movement trajectories, and coverage ranges. The former centers on a fixed tower and rotating boom, emphasizing “point coverage” and flexible horizontal rotation. The latter features a portal frame structure and longitudinal rail travel, prioritizing “extensive horizontal movement” and efficient on-site logistics handling. Consequently, their distinct structural designs directly dictate their differing application scenarios. Portal Crane Structural Characteristics Portal slewing cranes employ single/double cantilever boom structures with the tower fixed to foundations or rails, enabling 360° or partial rotation. This configuration enables flexible operation in narrow, elongated spaces such as shorelines, dock fronts, and ship berths, making it particularly suitable for ship-to-shore material handling. Its core functionality combines vertical…
In modern industrial operations, efficient material handling is crucial for maximizing productivity and optimizing workflow. Bridge cranes, also known as overhead cranes or EOT cranes, are fixed material handling systems widely used in manufacturing, metal processing, warehousing, and loading/unloading operations. In this article, we will explore the working principle, main components, applications, and operational benefits of bridge cranes, providing a comprehensive guide for industrial planners and logistics professionals. Bridge Crane Working Principle A bridge crane operates on a bridge-like structure spanning the workspace, with a trolley and hoist system that moves horizontally along the bridge and vertically lifts or lowers loads. The crane’s movement across the runway, combined with precise hoist control, enables efficient and safe handling of heavy materials in factories, warehouses, and industrial facilities. For information on how overhead cranes work, please see this article: Overhead Crane Working Principle: Components, Motion & Operating Process Bridge Crane Terminology The following is an introduction to terminology related to bridge crane parts. Crane Capacity: Crane capacity refers to the maximum weight a bridge crane can safely lift. Typically measured in tons…
An EOT Crane (Electric Overhead Traveling Crane) is an efficient and reliable overhead lifting system used to handle heavy materials in factories, warehouses, workshops, and industrial plants. Running on overhead rails, EOT cranes enable safe and precise three-dimensional movement of loads through coordinated lifting, cross travel, and long travel motions. This article will guide you through EOT crane definitions, types, structure, working principles, applications, and cost factors to help you select the most suitable solution for your lifting needs. How EOT Crane Works? The working principle of an EOT crane involves a combination of vertical lifting, horizontal trolley movement, and longitudinal bridge travel, enabling efficient handling of heavy loads across industrial facilities. The crane operates on elevated runway rails installed along the building structure, with the bridge girder spanning the workspace. The hoist mechanism raises or lowers the load using steel wire ropes or chains, while the trolley moves the load horizontally along the bridge. The entire crane travels longitudinally along the runway rails, enabling three-dimensional positioning of materials. Modern EOT cranes are powered by electric motors with precise speed…
