Wednesday, April 26, 2023, 16:06, Adam Newsome, T-Hall Crane, Maintenance, Target Hall Crane - Hoist Wire Wrapping
|
It was observed recently that the main hoist's wires seemed skewed, and there was occasionally some noise heard when raising and lowering the hook block.
It was suspected that this was due to wires having jumped in their tracks at some point. This is typically caused by side loading. It is possible that
wire wrap skew occurred during the incident outlined in e-log 46. |
