Selection Criteria Overhead Equipment

The choice of equipment to be applied to a given installation by the Application Engineer begins with the data as presented to him by the user. This point in the relationship establishes a communication link, which will decide whether or not the correct piece of Overhead Equipment is applied at the most economic advantage to the user. The role played by the user cannot be minimized. No one knows better than he, just what work he expects to accomplish with this piece of machinery. However, all too often, he oversimplifies the requirements, and along with minimal crane and building parameters, merely refers to one of the following crane classifications as defined by The Crane Manufacturing Association of America, as shown in Figures 1, 2, 3, 4, 5, 6 and 7. This approach places the ultimate user in an unfair position, since he has then assumed the status of the machinery designer and must, therefore, assume the responsibility of the success or failure of the operation of that piece of machinery. If the user selects a Class "C" crane for his job requirement, when actually a Class "B" crane can adequately handle the work load, he is not offering the most economic solution to his company and added little to the cranes service capabilities.
