An overhead crane is a type of crane found in industrial environments.which is a kind of hoisting machinery for lifting installed over workshop, warehouse and open storage area. It is commonly called a bridge crane because its both ends are located on the tall concrete pillars or metal supports, which looks just like a bridge. An overhead crane consists of parallel runways with a traveling bridge spanning the gap and a hoist, the lifting component of a crane, which travels along the bridge. The overhead crane, one of the most widely used hoisting machinery, characterize that the bridge move along the runways on the both side and the space below the bridge can be fully made use of without interference from the equipment on the ground. If the bridge is rigidly supported on two or more legs running on a fixed rail at ground level, the crane is called a gantry crane or a goliath crane.
 
 
Unlike mobile or construction cranes, overhead cranes are typically used for either manufacturing or maintenance applications, where efficiency or downtime is critical factors. Double girder Overhead Crane and Single girder Overhead Crane are two common kind of overhead crane.
 
 
Double-girder overhead cranes have the advantage of low overall height as the load hook can almost always be raised between the two crane girders. Double-girder overhead cranes can be equipped for cab or floor control, while the single-girder overhead cranes are designed to be controlled from the floor. offers the advantage of a low dead weight. In a word, single-girder overhead cranes are generally used when weight is below 50 tons and span is within 35 meters without any special operating requirement. If large span, high working speed and high dead weigh are required, double-girder overhead cranes will be more suitable.
 
 
Thus, when you decide to buy overhead crane, the first thing to do is to consider the possible factors such as useable range, working frequency, use ratio, and dead weight. Overhead crane supplier should be chosen by conducting market research based on a certain technical parameters. Most importantly, The Overhead crane supplier you choose must have the special equipment safety license.When you install the overhead crane, Overhead crane manufacturer with installing qualification should be chosen, which can provide one-stop service of manufacture, installation and commissioning. Overhead crane manufacturers like Otsego Crane & Hoist Co., Gorbel, Inc. and Sissco Hoist & Crane are experienced manufactures providing overhead handling solutions to customers in a wide range of industries.
 
 
After deciding the Overhead crane manufacturer, you should help the manufacture deal with report on starting construction for special equipment before installing the overhead crane. And then you must check whether organization scheme, installing equipment, installation procedures, technical requirements are in line with the requirements. After the installation, you should supervise the manufacturer to conduct a comprehensive self-checking and running test, load test. After confirming the crane is qualified, it then can be put into use.
