Today, I checked TH crane main hoist when shielding plug is installed into ITE pit. I did some jogging actions on main hoist during the operation.
Everything looks fine. No burning smell, no strange noise. An outside crane expert suggest that jogging is the worst working situation for crane. We have
to use jogging actions during our crane operation. But, we could try to use less jogging when operate the crane. |
