Port container gantry crane

The rail-mounted container door crane is the core equipment for lifting and stacking operations in container yards, and is widely used in logistics hubs such as bulk cargo yards and port terminals. This equipment has the characteristics of strong cross-column operation capability, high storage efficiency, excellent storage yard utilization rate, and convenient operation. It is an important support for improving the efficiency of logistics node operations. Its outstanding advantages are reflected in the following aspects:

• Stable structure, veilig en betrouwbaar: Finite element simulation is used to simulate a variety of actual working conditions to ensure that the whole machine has sufficient strength, stiffness and overall stability, and has excellent wind resistance, earthquake resistance, anti-collision and anti-overturning capabilities, ensuring safe and reliable operation of the equipment in various complex environments.
• Efficient anti-sway and smooth operation: Weihua independently developed a mechanical and electrical anti-sway system, which can realize two-way flexible damping and anti-sway of large and small vehicles, effectively suppress the swing of the spreader, greatly improve the efficiency of container loading and unloading, and ensure smooth and accurate operations.
• Excellent components and durable: The whole machine adopts fully digital AC frequency conversion speed regulation and energy feedback technology, combined with PLC control and CMS intelligent monitoring system, which can monitor the status of the equipment in real time and achieve predictive maintenance. The lifting mechanism supports constant power speed regulation, with smooth operation, small impact and low noise, which significantly improves the working environment.

Railway container gantry crane

◆ Hefgewichtbereik: 35t~45t

◆ Spanbereik: 20m-50m

◆ Functieniveau: A6-A8

Railway container gantry crane

Railway container gantry crane usually refers to the specialized application of rail-mounted container gantry crane (RMG) in railway freight stations and multimodal transport hubs. It is specially designed for the rapid loading, lossen, transfer and storage of railway containers. It is the core equipment that connects railway and road transportation and improves the efficiency of multimodal transport.

Its core advantage lies in relying on fixed rails to achieve efficient, nauwkeurig, and large-scale continuous operations, and deeply integrating the automation and intelligence requirements of the railway logistics system. The main technical features are as follows:

• Intelligent management: Integrate CMS (Crane Management System) or RCMS to monitor equipment status, operating parameters, and fault information in real time to achieve preventive maintenance and intelligent management.
• Precise anti-sway: Equipped with an electronic or mechanical anti-sway system to ensure minimal swing of the container during lifting, achieving rapid alignment and improving the loading and unloading speed of railway trains and trucks. Efficient connection: Containers can be transferred directly between railway flat cars and trucks or yards, achieving seamless sea-rail and road-rail connections of “getting off the train and boarding the ship/getting on the train”.
• Comprehensive protection: Equipped with multiple safety systems, such as wind alarm, dynamic scanning, anti-botsing, anti-lifting of trucks, automatic truck correction, enz., to ensure the safety of people, machines, en vracht.

Bridge container crane

◆ Hefgewichtbereik: 10t~60t

◆ Spanbereik: 10m-60m

◆ Functieniveau: A6-A8

Bridge container cranes are the core loading and unloading equipment in indoor container yards, cargo sheds and specialized container transfer stations. Its core advantage lies in making full use of the upper space to achieve large-span, opslag met hoge dichtheid, wide operating coverage, and smooth and accurate operation. It is especially suitable for efficient and continuous container handling and stacking operations under fixed workshops or cargo sheds. Its main technical advantages and features are as follows:

• Multi-functional configuration: Equipped with a special spreader and hydraulic grab, it supports quick switching and can stably complete container raw coal storage and loading and unloading operations in a -30°C environment. It has a reasonable structure and reliable performance.
• Efficient anti-sway: The lifting mechanism adopts an integrated design and is equipped with a self-developed two-way flexible resistance anti-sway system, which effectively suppresses the swing of the spreader and significantly improves loading and unloading efficiency.
• Intelligent control: Integrated intelligent control system supports semi-automatic and manual modes, and has operation recording, data analysis, status monitoring and chain protection functions to fully ensure the efficiency and safety of operations.
• Remote collaboration: Supports remote one-to-many collaborative operations, relying on high-precision sensing and automatic algorithms to achieve path planning and collision avoidance, greatly improving operation speed and accuracy and saving labor costs.
• Precise positioning: Equipped with a high-precision vehicle detection and positioning system, it can identify the position and status of the vehicle in real time, and intelligently link with the crane to achieve accurate and fast loading and unloading operations.

Rubber-tyred container crane (RTG-kraan)

◆ Hefgewichtbereik: 35t~50t

◆ Hefhoogte: 12m-18.5m

◆ Functieniveau: A6-A7

Rubber-tyred container crane (RTG-kraan)

The tire-type container gantry crane (referred to as tire crane or RTG) is a key mobile equipment in the container yard. Its core advantage lies in its excellent maneuverability and flexible site adaptability. It can move and transition freely within the yard without fixed tracks. It is especially suitable for port yards and intermodal transport yards with large container throughput and frequent adjustments to the container layout. Its main technical advantages and features are as follows:

• Flexible maneuverability and free layout: No need to lay tracks, relying on tires to travel, enabling cross-container area and cross-yard operations, and easy transition; the yard layout is flexible and can quickly respond to changes in the operation line, improving yard utilization and operation flexibility.
• Stable structure, veilig en betrouwbaar: Modern design methods such as finite element analysis are used to ensure that the gantry structure has sufficient strength, stiffness and overall stability under various working conditions such as moving and lifting; it is equipped with complete wind-resistant and anti-overturning devices and anti-collision systems to ensure the safe operation of the equipment in complex outdoor environments.
• Precise anti-sway and rapid alignment: Equipped with a high-performance electronic anti-sway system, it can effectively suppress the swing of the spreader and container, achieve fast and accurate container alignment, and significantly shorten the operation cycle time.
