Japanese Patent JP2001514609
Kind Code:
A
Abstract:
A ship unloader (1) including a jib crane (2) having a grab (10) mounted on a holding rope (11, 12). The holding rope (12) passes over a pulley (14) on the jib (3) to raise or lower the grab (10). A guiding sheave (20) slidably attaches a guiding rope (21) to the holding rope (11, 12) between the pulley (14) and the grab (10). The guiding sheave (20) is suspended from the jib (3) by a suspending rope (25) of variable length. A crowding winch (24) connected with the guide rope (21) draws and extends the holding rope (11, 12) so as to position the grab (10). The length of the suspending rope (25) is adjusted to control the position of the guiding sheave (20) along the holding rope (11, 12).
