Current Collector For EOT Crane, also known as a collector shoe or pantograph, is a crucial component in EOT crane systems. EOT cranes are used for material handling in various industries, and they run on tracks installed on the overhead structure.
The current collector is responsible for ensuring the continuous and efficient supply of electrical power to the crane's moving parts. It typically consists of a set of spring-loaded carbon brushes or other conductive elements that maintain contact with an electrified conductor rail or busbar system mounted along the crane's runway.
Here's how it generally works:
1. Collector Assembly: The current collector is usually mounted on the bridge or trolley of the EOT crane. It is designed to make reliable electrical contact with the conductor rail or busbar.
2. Conductive Elements: The collector shoe often contains conductive elements, such as carbon brushes or metal contacts, that make contact with the electrified rail.
3. Spring Mechanism: Springs are commonly used to ensure a constant and firm contact between the collector shoe and the conductor rail. This is important for maintaining a stable electrical connection, even when the crane is in motion or if there are slight variations in the height of the rail.
4. Electrical Path: The electrical path through the current collector allows power to be transferred from the fixed conductor rail to the moving crane. This power is then used to operate the crane's motors and other electrical components.
5. Maintenance: Regular inspection and maintenance of the current collector are essential to ensure optimal performance. Over time, the brushes or contacts may wear out and need replacement. The springs and other mechanical components also need to be inspected to prevent any interruptions in power transfer.
