A simple search for gantry cranes on the Internet will lead you to many different websites that sell them regularly. Some of them are portable, capable of only lifting 2 tons, yet there are others used for more industrial purposes that can lift 20 tons or more. Although the construction of each one is similar, in general, there are major differences due to how much weight they are capable of lifting. Here is a quick overview of how gantry cranes work (grúas portico trabajan), how the largest ones in the world are constructed, as well as how the smallest portable units can allow anyone to lift several thousand pounds on their own.
What Are 20 Ton Gantry Cranes Are Used For?
These cranes are very useful (son muy útiles) for not only lifting objects that are exceedingly heavy, but also moving them to different locations. For example, when you look at shipping yards where enormous ships are unloaded, these gantry cranes are actually taller than the ship, capable of using the hoist to lift and move the containers either onto the ship, or off of the ship onto the dock. The construction includes beams that come down to the ground, and a bridge girder where the trolley can move back and forth. If this is inside of a warehouse, the bridge girder will be attached to runway beams on either side, allowing it to move freight throughout the facility. These are typically able to move 20 tons (gruas son capaces de mover 20 toneladas) or more, using a hoist that can handle that amount. However, the smaller ones are designed and a slightly different way and will use a hoist with a smaller lifting capacity.
Overview Of 2 Ton Gantry Cranes
These cranes are very small by comparison and do not require any additional support from the structure that they are in. Although they are typically used inside, they can also be used for outdoor projects. They are easy to move around because of the wheels that can be locked and unlocked. The base on either side will be triangular informed to provide stability, with wheels on either end. The beam above where the hoist and trolley are connected is very similar to what you will see with the larger units. In some cases, it is only a hoist situated in the direct center to provide maximum stability.
A Comparison Between The Two
Based upon the description that has been given for each, the main difference between both of these units is their construction and size. Obviously, the smaller portable units will be much smaller, usually made of aluminum, making them very easy to maneuver. The construction differs in that 20 ton gantry cranes typically utilize runway beams located on either side of the complex where they are installed, whereas the 2 ton variety (variedad 2 tn) simply has the crossbeam and the hoist connected in the center. Both of them are very useful for their own reasons, and the prices can also be very different as well. A 2 ton gantry crane can cost as much as $2500 whereas a 20 ton gantry crane that has significantly more metal, and structural design, can cost tens of thousands of dollars.
