99903514: TELESCOPIC CRANE: 1-14 SECTION 1: OPERATION
1-10: CHANGING FROM DOUBLE TO
SINGLE-PART LINE
Initially, your crane is set up with two-part line.
Single-part line gives you a closer load distance
and faster line speed.
If you require a closer load distance or a faster
line speed, first check that you have the capac-
ity to lift your load using single part line. If you
do, change the crane to one part line using the
following steps:
1) Disconnect the pin which holds the hook/
snatch block assembly in place. Set aside the
pin and the snatch block.
2) Disconnect the double-line anchor pin.
3) Remove the downhaul weight from the crane
boom tip.
4) Slide the downhaul weight onto the wire rope.
Drop it into place on the hook. NOTE: Some
cranes have two hooks. Use the hook rated for
your load.
5) Lift your load. When finished, return the
boom tip to two-part line, or stow the snatch
block and pin.
