Poster L3 Iss 4

This poster is provided by the M&EE Networking Group to remind industry that when using a twin jib crane under the control of one operator then there is only the need for one Crane Controller. Where more than one TJC is used to lift a single load, this is classified as multiple lifting. Additional training and competence for the operators and Crane Controllers is required.

Added reference to Module P503 of the Infrastructure Plant Manual. Minor formatting changes.
