- Lifting speed: 1.5-11.5m/min
- Trolley running speed: 10-40.1m/min
- Crane running speed: 16-50m/min
- Work duty: A3-A7
- Rubber tyred gantry crane
Rubber tired gantry crane is a kind of portable lifting equipment with tyres attached to the bottom of the crane, making the movement more convenient and easier. According to different application requirements, the mobile gantry crane is designed with certain number of rubber tires. Thanks to strong mobility, this kind of gantry crane can reach each corner of the working area freely as well as be moved from one place to another easily.
The rubber typred portable gantry crane is widely used in port, quay and container terminals to load, unload and transfer heavy items. The most distinguished feature of the equipment is high flexibility and high utilization of working areas. If you are looking for a flexible lifting solution for outdoor application, the movable gantry crane is a preferred option.
- Semi gantry crane
Compared with traditional gantry lifting equipment, this type is built with single leg to fit many outdoor workplaces where the space is an issue. According to different lifting requirements, the semi gantry crane is configured with single girder or double girder.
- Truss gantry crane
Truss gantry crane is more often used for outdoor environments where there are strong winds. This outdoor truss gantry crane is suitable to undertake small and medium lifting tasks with many advantages such as light dead weight, small windward area and easy maintenance.
- Cantilever gantry crane
The gantry crane can be designed with outreach on both sides of the main beam to form cantilevers which effectively increase the workspace. The gantry crane with cantilever is widely used in various open workplaces, such as port, railroad freight yard and shipyard.

Another critical consideration is the working environment. As the outdoor environments are changeable, you may need to configure your crane with several protection devices such as wind proof device, lightning protection device and rain cover.
Then you should think about questions like how often do you use the crane, which way do you prefer to make it move, rubber tyred or rail mounted?
Finally you should consider some options for critical parts of the crane such as the trolley and hoist type.
Other important factors involving in selecting an outdoor lifting equipment mainly include the cost of the crane, quality, service and qualification of suppliers. We suggest you to take a comprehensive consideration of these questions so as to make the best choice. We will help you find the best lifting system for your practical needs.
Safety Devices for Outdoor Gantry Crane
For gantry lifting system used in outdoor places, the working environment are uncontrollable, so it is critical to outfit safety devices to ensure an efficient and secure operation.
Wind proof and anti-slip device. According to relevant regulations, the rail mounted gantry crane for outdoor uses should be equipped with this protection device in case the equipment is blown by strong winds, leading to slide along tracks. Based on different operation modes, this device can be classified into three types: manual, automatic and semi-automatic.
Anti-collision device. The device is suitable for occasions where there are more than two gantry cranes traveling along the same rail. It is used to prevent collision between these cranes.
Rain cover and lightning protection device. For open-air working environment, it is essential to equip these safety devices in order to protect the electric control system of the crane.
