Travelling 5t-320 ton Electric Double Beam Bridge Crane with Hoist Equipment

Product Description:

Double girder bridge crane is a lifting equipment which is transversely mounted over workshop, warehouse and material yard for material hoisting. It is a heavy-duty crane running on rails. Because its two ends are situated on tall cement columns or metal brackets, they resemble bridges. The bridge of double-girder bridge crane runs longitudinally along the rails laid on both sides of the viaduct. It can make full use of the space under the bridge to lift materials and is not hindered by ground equipment. It is the most widely used and the largest number of lifting machinery. Its applicable lifting weight is 5t-320t, its applicable span is 7.5m-31.5m, and its working environment temperature is in the range of -25-40 ~C.

General descrption:

Two girders are simply stronger than one, making double girder traveling cranes the ideal solution for the area coverage handling of heavy loads up to 32/5t. Like all factory cranes, these units are available with a number of main girder connection versions to best suit new or existing buildings and the best in functionality, versatility and convenience. double girder cranes feature welded box beams. All the sections used for main girders and end girders are computer-optimized for high performance and low weight, benefits that pay in terms of strength and cost efficiency.
