Large overhead cranes play a critical role (papel crítico) in many industries. These cranes are used to lift heavy objects and move them around the factory floor or up to higher storage. There are 10 ton and 20-ton (10 ton y 20 ton) cranes that are used to lift various pieces of equipment, especially during the deployment of military organizations. These cranes lift the equipment up and place it for transport to the new area or facility. One of the benefits of a good overhead crane is that it can lift an extremely heavy load with just the push of a button. Even so, the crane operator must be trained in moving and manipulating the load and the crane to ensure there are no accidents or injuries during crane operation.
There are many types of cranes and the most common size are cranes with a 10 or 20-ton lift capacity. These cranes are used in almost every industry (cada industria) and are especially helpful in warehouses and factories. Some overhead cranes are used in shipyards to load and unload ships while they are sitting in port. Overhead cranes are popular for a number of reasons.
First, they are perfect for moving very heavy loads quickly and safely (rápida y segura) from one location to another. What might take a group of fifteen or twenty men several hours takes an overhead crane just a couple of minutes and can be done with a single crane operator.
Overhead cranes are generally less expensive than extra manpower (mano de obra extra) to move heavy loads. They are also safer and last longer.
Overhead gantry cranes and bridge cranes generally have high lifting capacity. These cranes can lift 10 or 20 tons with ease.
Overhead cranes can easily move heavy loads from one place to another and never bring the load to the floor. Gantry and jib cranes can lift as much as 20 tons and carry it to another location on the upper levels of a warehouse or factory (almacén o fábrica). Gantry cranes can move loads to almost any height. All that is required is a simple adjustment in the height of the crane.
Telescopic cranes carry a boom that can be expanded to reach areas farther away than can be accessed by traditional types of overhead cranes. These cranes are good for moving about on a factory floor where there are often obstructions in the path (el camino) of the crane.
A tower crane is fixed in a permanent position, often anchored to the floor. These types of overhead cranes usually have a greater lifting capacity since they are grounded and stabilized (estabilizado). However, they are limited in how far they can move a load once it is lifted.
Some overhead cranes can be mounted on mobile platforms (plataformas móviles) and moved from one location to another. These cranes can generally lift up to 20 tons or more and move the load safely to another position. This type of crane is often used when moving equipment parts for assembly in another location.
Overhead cranes are found in almost every industry, from manufacturing (fabricación) to transportation and logistics. The most common lifting capacity for an overhead crane is 10 to 20 tons, although some cranes will lift several hundred tons.
