EOT (Electric Overhead Traveling) cranes are widely used in industries like manufacturing, steel plants, warehouses, and construction. The control panels for EOT cranes are critical for safe, efficient, and reliable operation.
1. What are EOT Crane Panels?
EOT crane control panels house electrical and electronic components that control:
Hoisting (up/down)
Long travel (forward/backward)
Cross travel (left/right)
Braking systems
Safety interlocks
