(1) When the assistant guides the hoisting rope to the rope pulley on the
boom head, the crane operator must operate the reeving winch. This
procedure must be done in such a manner that the rope does not slacken
up on the winding drum.
(2) Reeving can be done manually or with the help of a reeving winch.
If the reeving winch is used, the rope on it must first be reeved in reverse
direction between the hook block and the rope pulleys on boom head and
then connected with the hoisting rope of winch 1 (or winch 2).
(3) Reeving winch and hoisting winch synchronisation
Procedure for this operation: (taking hoisting winch 1 as working winch)
1)
Turn “synchronization switch” to the left “Reeve SYNC” gear, which is described as
above;
2)
Push right control lever forwards and backwards, the reeving winch and hoisting
winch 1 will carry out synchronous movements, namely, reeling off hoisting winch 1
and spooling up reeving winch, or spooling up hoisting winch 1 and reeling off
reeving winch.( Push left control lever forwards and backwards, the reeving winch
and hoisting winch 2 will carry out synchronous movements. namely reeling off
hoisting winch 2 and spooling up reeving winch, or spooling up hoisting winch 2 and
reeling off reeving winch)
3)
After hoisting rope is reeved well, return the “synchronization” switch to neutral
position, and remove the rope lock connecting the reeving rope and hoisting rope.
Finally wind the reeving rope onto the reeving winch.
(1) The operation mentioned above must be carried out by at least tow persons.
(2) After the hositing rope is reeved correctly between rope pulleys, the
“synchronization” switch must be returned to neutral position.
