Selecting the right double-girder gantry crane for your business is important if you want to get the greatest possible benefit out of your investment. Anytime you purchase a large piece of equipment like this for your business, you should put careful thought into the decision-making process. In this case, that means considering all of these factors:
1. The load rating of the crane. Cranes(Grúas) are rated based on the amount of weight they are capable of carrying. Double-girder cranes are usually designed for extremely heavy lifting, ranging anywhere from 15 tons up to 500 tons or more. When buying a crane, determine the maximum amount of weight that you need to lift and move. Then, make sure that the model you purchase is capable of handling at least that much weight. You may even want to think about buying a crane that is a little bit oversized to reduce the risk of accidentally overloading it.
2. The span of the crane. Another major consideration is the total distance that you need the crane to span. The longer the distance is between the two legs, the stronger the crane needs to be to support the weight of the load.
3. The overhead clearance requirements. You also need to think about the amount of overhead clearance that the crane will provide. One of the benefits of using double-girder cranes is that the trolley can run on top of the girders, providing additional overhead clearance. That makes these cranes a great choice for use in buildings with low ceilings or in other situations where the amount of overhead space is limited. The hook height should be tall enough to provide plenty of clearance in the area where you plan on using the crane.
4. The wheel style. Gantry cranes are usually mounted on wheels. Some models are equipped with rubber tires(neumáticos de goma), allowing them to glide smoothly over just about any smooth surface. Cranes that are designed to carry heavier loads sometimes run on metal wheels like a train. The choice of wheels usually depends on the overall lifting capacity of the crane as well as the conditions under which it is going to be used.
5. The reputation of the manufacturer. Double-girder gantry cranes(grúas pórticos birrailes) are built to carry loads that are extremely heavy. To prevent accidents or injuries, the crane itself needs to be constructed to the highest standards. Buying a crane from a trusted manufacturer is the best way to ensure that it has the quality that you need. Avoid the temptation to save money by purchasing from a lesser-known company. It is worth the extra investment to buy a high-quality crane from one of the leading companies in the industry.
The process of selecting a double-girder gantry crane requires careful consideration. It isn’t a decision that should be made lightly. All of the factors in the previous section need to be carefully evaluated to find a crane(encuentra una grúa) that is capable of meeting the needs of your business. By working closely with a qualified manufacturer, you can determine which crane is best suited to your specific situation.
