Guide channel for service lines in conveyors and cranes

摘要

The guide channel for energy supply lines has a static construction (6) for mounting to a static section of the crane base. A moving channel (7) pivots on a rotary axis (8) against the static section (6). An intermediate channel (9) is mounted on the main channel, rotating on a second axis (10) parallel to the first (8). All three structures (6,7,9) have channel sections (11-13) with their ends aligned when the lower structure is not moved. When the sections move in relation to each other, the control sets the movement of the moving (7) and intermediate (9) sections to travel past each other.
