Working area diagram
Bold lines determine the limiting position of any load for operation within working areas indicated.
When lifting over swingaway and/or jib combinations, deduct
total weight of all load handling devices reeved over main
boom nose directly from swingaway or jib capacity.
NOTE: All load handling devices and boom attachments
are considered part of the load and suitable allowances
MUST BE MADE for their combined weights. Weights are for
Grove furnished equipment.
