Load testing is one of the most important tests performed on overhead crane equipment. Load testing involves loading a crane to verify the maximum performance level of the structure, hoisting equipment and control systems. Load testing is used to verify the maximum, safe load capacity of crane systems. These tests include a variety of conditions and … Read more
Overhead crane design has evolved over the last hundred years to include a variety of sizes, applications, and general uses. Overhead cranes are the most common type of industrial crane design, and are invaluable in manufacturing, material handling, and storage applications. Here we will discuss the most common types of overhead cranes used in modern manufacturing. … Read more
Bridge cranes and gantry cranes are similar in both design and function. Both types of overhead cranes are designed to perform repetitive hoisting actions, in warehouses and heavy manufacturing factory floors. Bridge and gantry cranes are extremely strong in design, and do not depend on cantilever leverage, but rather the strength of a winding cable … Read more
First—What it is Not! The construction industry relies on heavy, tracked cranes (think ‘crawler crane’) to do a majority of its lifting, most of which is out-of-doors. This is not at all what we are talking about in this article. We are concerned largely with indoor applications in this overview. Although it’s a critical piece of infrastructure, … Read more
Cranes must be adequately serviced and inspected prior to use to prevent unexpected failure and personal injury. Cranes are designed for a specific purpose and must be maintained to perform the job they are designed to do, or they can become extremely dangerous. Crane operators are highly trained in the use and operation of cranes, and are … Read more
Overhead Bridge Cranes: Single Girder and Double Girder Cranes To the casual observer cranes look very much alike. Besides a girder crane, other members of the family include overhead cranes, single girder cranes, and double girder cranes. We also have the bridge cranes, double girder overhead crane, the single girder overhead crane, double girder crane, … Read more
Cranes are helpful machines, but they can also be quite dangerous. Even small cranes are capable of lifting extremely heavy loads, so it’s essential that they follow the strictest safety requirements to ensure safe operation for everyone. The American Society of Mechanical Engineers (ASME) put together a set of safety standards that all crane owners, manufacturers, … Read more
Crane systems can be quite complicated, and every part is crucial to the efficiency of the system as a whole. One of the most important parts of a crane is the reeving system, which affects elements like lifting capacity, overhead space, lift speed, and lateral movement. So, what is crane reeving? What Is Crane Reeving? … Read more
Is a top running or underhung bridge crane appropriate for your facility? Learn more about how to make this determination, the pros and cons of each configuration, and factors to keep in mind as you evaluate what’s best for your business. When selecting a bridge crane, there are several important design criteria that you will … Read more
When looking at injury statistics, cranes are often cited as being the most dangerous piece of equipment on site. One article states that approximately 80% of crane accidents are a result of operators exceeding the crane’s capacity. Further, the Bureau of Labor Statistics notes that “just over half of all fatal crane injuries involved the worker being struck by an object … Read more
