A Gantt chart is a project management tool assisting in the planning and scheduling of projects of all sizes, although they are particularly useful for simplifying complex projects. The operator must begin hoisting the load to determine, using a load weighing device, load moment indicator, rated capacity indicator, or rated capacity limiter, if it exceeds 75 percent of the maximum rated capacity at the longest radius that will be used during the lift operation. Structural capacities in a load chart are distinguished by:Shaded area, above a bold line, in bold type or marked with an asterisk *. The values given in the charts are \"Gross Capacities\" or \"Rated Capacities\". Load charts have become increasingly complex. In many cases, there is a need to use the same circuit to match a broad range of load impedance and thus simplify the circuit design. GROVE RT855B.
