can you possibly claim that two men only need 15 minutes to reeve the
K-10000 hoist rope. I have been operating large mobile cranes for
many years, and it is always several hours of hard work for 3-4 men to lay
on a new rope or to change from two to six lines.
We have never claimed that two men can lay on a new
rope in 15 minutes; that may take 3-4 men a whole day. There is
slightly over 4,000 ft of rope.
What we do claim is that two men, the operator plus
one man on the ground, can change the reeving from 2 to 6 parts or
from 6 to 2 parts in less than 15 minutes, 5 minutes is possible, and
neither of them will have touched the rope.
We further claim that the operator plus two men on
the ground can change the reeving from 6 to 12 parts or from 12 parts to 6
parts in less than half an hour, 15 minutes is possible, and none of the
three will have touched the rope.
Because of the way it is done, it does not matter
much whether it is raining, snowing or windy.
The reeving change is difficult to explain in just
words, but easy to understand on photographs. The process is
explained and richly illustrated in THE
CONVERTIBLE HOISTING BLOCK, which you would encounter under A FEW
PHOTOS or TROLLEY on the Detail Selection Page.
