Do not exceed parts of line ratings.

  1. Load does not include blocks, slings, and all other equipment used to handle objects being lifted.
  2. Load ratings are for zero degree list.
  3. Loads must be freely suspended.
  4. Rope: Rotation resistant, compacted strand, 9080 lb. capacity.
  5. This chart is only a guide and should not be used to operate the crane. Individual crane’s load chart, operating instructions, and other instructional plates must be read and understood prior to operating crane.
