The working class of a bridge crane indicates the intensity of its operational workload, specifically reflecting the time-based workload and load capacity of the crane. Hook-type cranes are classified into three levels and seven categories: A1-A3 (light duty); A4-A5 (medium duty); A6-A7 (heavy duty). The magnitude of a bridge crane's duty class is determined by two capabilities: the frequency of crane usage, termed the utilization rate; and the magnitude of loads borne, termed the load condition. During its effective service life, a bridge crane undergoes a specific total number of duty cycles. A duty cycle encompasses the entire operational process from preparing to lift a load until the next lifting operation commences. The total number of work cycles indicates the crane's utilization rate and serves as a fundamental parameter for classification. This total represents the sum of all work cycles performed during the specified service life. Determining an appropriate service life requires consideration of economic, technical, and environmental factors, while also accounting for the effects of equipment aging.

What is the span of a bridge crane?Bridge cranes are the most commonly used lifting equipment in workshops. The span of a bridge crane refers to the distance between the centerlines of the two rails on its running track. It is denoted as: L. The unit is typically: M (meter).The span of a bridge cran

How to Prevent Rust on Idle Metallurgical Cranes?We all know that rust prevention is crucial for equipment that has been idle for extended periods. For lifting equipment like metallurgical cranes and gantry cranes, how should rust prevention be carried out when they are left unused for long duration

Driven by demands for energy efficiency, environmental protection, and economic viability, coupled with continuous improvements in foundry production efficiency, the demand for bridge cranes transporting molten metal is growing significantly. Such cranes are commonly referred to as metallurgical cranes, metallurgical hoists, or foundry cranes.
