What is a gantry crane?

Gantry crane is a large lifting equipment running along the ground track, often used outdoors or in places without travel beam support, such as freight yards, docks, storage bases, railway freight stations, etc. It uses the columns and beams on both sides, with electric hoists or open winches to lift and move heavy objects horizontally, achieving efficient and stable loading and unloading operations.

Gantry cranes are divided into several types according to their structure and purpose:

Single-girder gantry crane: simple structure, suitable for small and medium-sized tonnage lifting;

Double-girder gantry crane: stronger bearing capacity, suitable for large tonnage and heavy load operations;

Semi-gantry crane: suitable for sites with columns on one side and factory walls on the other side;

Container gantry crane (RTG, RMG): used for container loading and unloading, and is standard equipment for port logistics.

Application scenarios of gantry cranes

• Port container terminal

• Steel storage and processing center

• Prefabricated component factory and bridge engineering

• Railway station freight platform

• Aerospace manufacturing company

•  

  Wind power equipment assembly site

   

 Features

1. Stable structure and strong adaptability
It adopts a portal structure design, consisting of a main beam, legs, and ground beam, with good load-bearing stability;
It can operate independently in outdoor environments without a factory or a driving beam, and adapt to various complex terrains.

2. Strong load-bearing capacity
It can be designed in a variety of specifications from 5 tons to 320 tons, meeting the lifting needs from small and medium-sized materials to heavy equipment;
It is particularly suitable for large-tonnage handling operations such as steel structures, shipbuilding, railways, and bridge construction.

3. Track operation and wide coverage
It walks along the ground track, has a large working range and flexible layout, and can make full use of the site area;
It can be customized by gauge and span to cover working areas of different widths.

4. Easy installation and flexible disassembly and assembly
Compared with bridge cranes, it does not require upper structure support and has a short installation period, which is especially suitable for temporary work sites;
It is easy to disassemble and relocate, can be reused, and is suitable for construction sites or rental businesses.

5. Multiple control modes
Supports multiple operation modes such as ground handle control, wireless remote control, cab control, etc.;

Can be used with intelligent systems to achieve remote control and status monitoring to improve the level of automation.

6. Good safety performance
Optional safety devices such as windproof anchoring device, anti-collision system, limiter, overload protector, etc.;

For outdoor operations, the equipment has good rainproof, dustproof and corrosion-resistant properties.

7. Low maintenance cost
Simple structure, standardized components, easy maintenance;

Low long-term use cost, economical and durable, it is the preferred solution for many companies.
