Bridge cranes and gantry cranes have similar functions and are used to lift objects for transportation and hoisting. Some people may ask whether bridge cranes can be used outdoors? What is the difference between bridge cranes and gantry cranes? The following is a detailed analysis for your reference.
1. Can bridge cranes be used outdoors?
Can the bridge crane be used outdoors? No, because its structural design does not have outrigger design. Its support mainly relies on the brackets on the factory wall and the rails laid on the load-bearing beams. The operation mode of the bridge crane can be no-load operation and ground operation. Idle operation is cab operation. Generally, ground operation is selected and the remote control is used. The operation is simple and safe.
2. The difference between bridge crane and gantry crane
Currently, there are many types of bridge cranes and gantry cranes on the market. Customers choose bridge cranes or gantry cranes according to their own needs, mainly in terms of equipment structure, working method, price, etc.
1. Structure and working mode
The bridge crane is composed of a main beam, a motor, a winch, a trolley traveling mechanism, and a trolley traveling mechanism. Some of them can use electric hoists, and some can use winches. The size depends on the actual tonnage. Bridge cranes also have double girder and single girder. Large-tonnage cranes generally use double beams.
The gantry crane is composed of main beam, outriggers, winch, cart traveling, trolley traveling, cable drum, etc. Unlike bridge cranes, gantry cranes have outriggers and can be used indoors and outdoors.
2. Working mode
The working mode of the bridge crane is limited to indoor operations. The hook can use double electric hoists, which is suitable for lifting in processing plants, automobile factories, metallurgy and general industrial plants.
Gantry cranes work in a variety of ways, usually with small tonnage indoors, shipbuilding gantry cranes and container gantry cranes outdoor, which are large-tonnage lifting equipment, and container gantry cranes are used for port lifting. This gantry crane adopts a double cantilever structure.
3. Performance advantages
Bridge cranes with high working levels generally use metallurgical cranes, which have higher working levels, good performance, relatively low energy consumption, and comply with environmental standards.
The working level of gantry cranes is generally A3, which is for general gantry cranes. For large-tonnage gantry cranes, the working level can be raised to A5 or A6 if customers have special requirements. The energy consumption is relatively high and it meets environmental protection standards.
4. Equipment price
The crane is simple and reasonable, with low operating costs. Compared with the gantry crane, the price is slightly lower. However, the two still need to be purchased according to demand, and the two forms are not the same. However, the price difference between the two in the market is still relatively large, which affects the price. There are many factors, so the prices are different. The exact price needs to be determined according to the specific model, specifications, etc.
