Overhead cranes are becoming symbolic of manufacturing plants, warehouses and shipping yards. As lifting equipment, they are typically the most beneficial lifting equipment option offered to managers and operators of plants and warehouses.
However, using the current market selections of either a double girder or buying single girder overhead crane, managers or plant operators run the potential risk of as being a tad confused thereby buying inappropriate equipment.
Herein we require a candid examine several of the elements that differentiate the 2 systems available for sale. The purpose of this piece to further improve buyers?capability to buy an overhead crane system which will fully meet their needs while as well being economical in the original purchase as well as the long-term running costs.
Exactly What The Two Systems Are
Single Girder Overhead Crane – This is basically the overhead crane that includes single girder/beam that forms the bridge running throughout the two runway rails. Under the single girder, the hoist is installed. (The hoist will be the part within the overhead crane that accounts for lifting mechanism.)
Double Girder Overhead Crane – The double girder overhead crane, on the other hand, consists of two girders/beams side-by-side running across the two runway rails. This particular system offers the lifting device install along with the bridge and linked to both girders.

The Operating Differences
Besides the variations in the systems structure that exist between the two crane systems, in addition there are operating differences. Many of them include:
Overhead Clearance ?Overhead room is definitely the maximum distance possible between the floor along with the hook from the lifting system. The one girder operates within a shorter headroom. This is because the hoist method is installed under the girder, thereby using up more headroom. On the other hand, the double girder operates with a tad more headroom. Better headroom emanates from the lifting device being installed along with the girder. This clears the headroom around the quantity of the girder.
The one girder is, therefore, the best choice for a plant which has little room in between the girder and runway rails and the roof. Also, it is the most appropriate to get a plant that is not responsive to headroom space. The perfect industrial overhead crane is the ideal selection for plants that require maximum utility of the headroom.
Lifting Load Rating ?Although among lower weight ratings you can find both single and double girder, higher weight rated magnetic overhead crane design structure can be a preserve of your double girder cranes. The double girder structure is much more stable and therefore stronger enough to stand up to the heavy weight involved. In this regard, it is actually more readily found a 50-ton double girder overhead crane than finding a 50-ton double girder overhead crane.
The Variations In Pricing
There exists a marked difference regarding the cost of every one of system. The double girder is generally much more expensive compared to the single girder overhead crane, even throughout the same weight load rating. There is mainly due to the extra quantity of components working in the production of the double girder overhead crane.
With considerations of the price tag on the 2 cranes and the working dynamics from the each at heart, you should find it easier to choose the best option that works well with you.
