GRT8120 OPERATOR MANUAL SET-UP AND INSTALLATION
HOIST ROPE REEVING
NOTE: 35 x 7 (rotation resistant) hoist rope is used on this
crane.
Within load and range chart limits and permissible line pull,
multi-part line reeving allows the operator to raise a greater
load than can be raised with a single line part. A qualified
rigger should do the reeving using standard rigging
procedures. The load lifted must be within the limits
contained in the load chart.
Possible Reeving Combinations
NOTE: The maximum load bearing capacity of individual
hook blocks does not correspond to the maximum
load bearing capacity of the TMS9000-2 together
with this hook block. The load bearing capacity of
the TMS9000-2 depends on the rope pull, the
reeving and friction force. It is lower than the load
bearing capacity of the hook block.
NOTE: Please note that the maximum load bearing
capacities already include the weight of the hook
block and the lifting gear. You must subtract these
weights in order to obtain the actual payload.
NOTE: The recommended hook-blocks are designed to be
of sufficient weight to overhaul the rope properly
when using the parts of line required for the allowed
load at the chosen boom length. Operating with a
higher number of parts of line than is necessary for
a particular boom length may result in poor rope
spooling behavior and loosely stored rope, which
can result in future rope damage. If operation in
these extended ranges is desired, extra weight
should be carried by the hookblock or a heavier
hookblock should be used.
