These patterns represent some, though not all, of the options for reeving patterns for
hookblocks. Always use a reeving pattern that allows the block to hang level.
When reeving the crane in preparation for any job, it should be kept in mind that hoisting
and lowering speeds decrease as the number of parts of line increases. For the most
efficient use of the crane, it is therefore desirable to use the minimum required number of
parts for lifting the load as determined by referring to the load rating chart.
This crane incorporates a “Quick Reeving” boom head and block which do not require
removal of the wedge and socket from the rope in order to change the reeving. Removal of
two pins in the boom head and three in the hook block will allow the wedge and socket to
pass through.
Never use less than the number of parts called for by the load rating chart.
If it is not practical to alter the reeving during the course of the work, the required number
of rope parts must be determined on the basis of the heaviest load to be lifted during
operations.
When the required number of rope parts has been determined, reeve the rope as shown
above. Attach a wedge type rope socket to the wire rope dead end and secure it to either
the boom peak or hook block as required. Dead end the rope on the hook block for an odd
number of line parts, and on the boom peak for an even number of parts.
As shipped from the factory, the crane has sufficient wire rope provided to allow the hook
to each ground level with any boom length and elevation when reeved with minimum parts
