Overhead cranes and gantry cranes have similar functions, both are used to lift objects for transportation and lifting. Can overhead cranes be used outdoors? What is the difference between an overhead crane and a gantry crane?
1.Can overhead bridge cranes be used outdoors?
No, because its structural design has no outrigger design, its support mainly depends on the brackets on the plant wall and the steel rails laid on the load bearing beams. The overhead cranes can be operated in idle operation and ground operation. Idle operation is cab operation. The ground operation is usually chosen to use the remote control, which is easy and safe to operate.
2.Difference between overhead bridge cranes and gantry cranes
Structure and working mode
Overhead bridge cranes are composed of main girder, motor, winch, large traveling, small traveling, etc.. Some of them can use electric hoist, some use winch, the size depends on the actual tonnage. There are also double girder and single girder overhead cranes. Large tonnage cranes generally use double girder.
Gantry cranes are composed of main girder, outriggers, winches, trolley travel, trolley travel, cable reels and so on. Unlike bridge cranes, gantry cranes have outriggers and can be used both indoors and outdoors.
Working mood
Overhead cranes are limited to indoor work, the hook can be double electric hoist, suitable for processing plants, automobile factories, metallurgy and general industrial plant lifting.
Gantry cranes work in a variety of ways, usually indoor small tonnage, shipbuilding gantry cranes and container gantry cranes outdoor, are large tonnage lifting equipment, container gantry cranes are used for port lifting. This type of gantry crane adopts double cantilever structure.
Performance advantages
Overhead cranes with high working level are generally used metallurgical cranes, this working level is higher, good performance, while energy consumption is relatively low, in line with environmental standards.
Portal crane working level is generally A3, which is for general portal cranes, for large tonnage, customers have special requirements of the working level can be adjusted to A5 or A6, energy consumption is relatively high, in line with environmental standards.
Equipment prices
Crane simple and reasonable, low operating costs, and gantry cranes compared to the price is slightly lower, but the two are still based on demand, and the two forms are not the same, but the price difference between the two on the market is still relatively large, the impact of the more manufacturers to choose and so on, so the price is not the
