Overhead cranes have grown to be symbolic of manufacturing plants, warehouses and shipping yards. As lifting equipment, they are typically the most efficient lifting equipment option available to managers and operators of plants and warehouses.
However, using the current market choices of either a double girder or single girder overhead crane, managers or plant operators run the potential risk of as a tad confused thereby buying inappropriate equipment.
Herein we go on a candid take a look at a few of the elements that differentiate the two systems available in the market. The objective of this piece to improve buyers?capability to buy an overhead crane system that may fully meet the requirements while simultaneously being economical both in the initial purchase along with the long-term running costs.
Just What The Two Systems Are
Single Girder Overhead Crane – This is basically the overhead crane that consists of a single girder/beam that forms the bridge running throughout the two runway rails. Beneath the single girder, the hoist is installed. (The hoist may be the part in the overhead crane that accounts for lifting mechanism.)
Double Girder Overhead Crane – The double girder 100 ton overhead crane, on the other hand, includes two girders/beams side-by-side that run over the two runway rails. This kind of system has the lifting device install on top of the bridge and attached to both girders.
The Operating Differences
Apart from the variations in the systems structure that can be found between your two crane systems, there are also operating differences. Many of them include:
Overhead Clearance ?Overhead room is the maximum distance possible involving the floor and the hook from the lifting system. The single girder operates in a shorter headroom. The reason being the hoist method is installed below the girder, thereby taking on more headroom. Alternatively, the double girder operates using a tad more headroom. Better headroom emanates through the lifting device being installed on the top of the girder. This clears the headroom around the amount of the girder.
The one girder is, therefore, your best option for a plant which has little room involving the girder and runway rails and the roof. It is also the best to get a plant that may be not responsive to headroom space. The double girder overhead crane is the greatest choice for plants which require maximum utility of the headroom.
Lifting Load Rating ?Although among lower weight ratings you will discover both single 1 ton overhead crane and double girder, higher weight rated cranes really are a preserve in the double girder cranes. The double girder structure is a lot more stable and so stronger enough to withstand the heavy weight involved. In connection with this, it is actually more readily found a 50-ton double girder overhead crane than locating a 50-ton double girder overhead crane.
The Variations In Pricing
There exists a marked difference regarding the price tag on all of garage overhead crane system. The double girder tends to be considerably more expensive compared to the single girder 5 ton bridge crane, even inside the same weight load rating. There is certainly mainly as a result of extra amount of components working in the manufacture of the double girder overhead crane.
With considerations of the cost of both cranes as well as the working dynamics from the each in your mind, you need to find it easier to choose the best option that works the best for you.
