The Load Charts in this section are taken from the Load Chart Manual which has been published by NCCCO in cooperation with crane manufacturers to help candidates prepare for CCO written examinations. In some cases only excerpts of the load chart have been included and, therefore, they are not to be used for actual crane operation. If you need a load chart for a specific crane, you should contact the appropriate manufacturer or an official distributor.
