EOT cranes are one of the types of cranes that are used for transferring or loading heavy things for some definite work. EOT cranes are equipped with a derrick or a tower is used to lower and lift the materials with the help of pulleys and cables. Construction industries use these cranes according to their process in connected activities. The cranes used in construction industries mostly are of temporary structures. These machines are controlled by different methods such as radio control, infrared control or built in control station using a push button pendant or by an operator sitting in the cab of the vehicle. A standardized hand signal is used between the person operating the controls and workers in the ground. For bigger installation radio communication is used. Now you are thinking how it works? Well, its rational structure is of box construction adequately designed by ribs. It is connected with a bridge trolley which is moved by motors. Electromagnetic brakes are used to control the smooth lifting of weight. A hook is equipped with wire rope. Electric operations are controlled with push button sliding in loop through cable carriers. Now I will tell you about the history of EOT cranes as who were the first to use it? Or who invented it and many other questions like that. So, the cranes were found to be very useful since the starting of the history. The Greeks were the first people who use these cranes in the late 6th century. They used these cranes for lifting heavy and weighted materials. After Greeks, many other people like Roman and Chinese used this crane for same purpose and also made some changes regarding designs. EOT cranes are divided into two formats and these are single grider eot crane and double Girder EOT crane. The market of these eot cranes is spreading like a spider's web. Single girder EOT cranes also differ on the basis of running design. These cranes are divided in top running and under running design. These cranes are made from quality raw materials and are tested on various parameters. Two girder EOT cranes differ on the basis of load capacities. After knowing its types we will discuss about its features which are mentioned below: Easy to install Reliable structure Single or double speed type Cheaper in cost Higher efficiency in saving power. Available with radio remote control system. Rubber buffers are provided for extra protection. Easy to maintain. Fail safe type breaks, etc.
