The difference between gantry crane and bridge crane
Gantry cranes and bridge cranes are the secondary classification under the classification of bridge type cranes and boom type cranes, and their styles, performances and other aspects are different;Here is an example of double girder bridge crane and double girder gantry crane
1. Similarities
It can be applied to the working environment of indoor lifting and hoisting, most of which are driven by electric power. When rainproof equipment or rainproof measures are installed, it can be operated outdoors.
Two, the difference
1: The shape is different.
①Bridge crane (like a moving bridge)
②Gantry crane (looks like a moving door frame)
2: The running track is different.
①The bridge crane is a lifting equipment that is horizontally framed on the rails of the fixed crotch pillars of the building and is used in workshops, warehouses, etc., indoors or in the open air for loading, unloading, and lifting.
②Gantry crane is a variant of bridge crane, also known as gantry crane. There are two tall legs at both ends of the main beam, which run along tracks on the ground.
3: The application scenarios are different.
①The bridge frame of the bridge crane runs longitudinally along the tracks laid on the elevated bridges on both sides, which can make full use of the space under the bridge frame to lift materials without being hindered by ground equipment. It is a kind of hoisting machinery with a wide range of use and a large number, and it is more common in workshops, warehouses and other indoor areas.
②Gantry cranes have the characteristics of high site utilization, large operating range, wide adaptability, and strong versatility, and are widely used in port freight yards.
The gantry crane has legs and the wheels are on the ground (the rails are laid on the ground); the bridge crane is in mid-air, and the wheels are on the beams of the pillars (the beams are laid on the beams), and the beams are erected on the brackets (horns) extending from the pillars.
