Device for guiding the loading rope on the jib head of a mast or on-board crane

The innovation relates to a device for guiding the loading rope on the boom head of a mast or board crane by means of a Role.

It is known to have a block at the top of the tree in loading trees . to arrange through which the loading rope is passed. This arrangement. does not cause any problems because the loading rope is guided along underneath the tree in the case of loading trees. This makes it possible Swing the block at the top of the tree to both sides so that the trees are on the port and starboard mast can be executed immediately.

Does the loading rope of a mast crane run for static reasons? not below the boom but between the boom head and the hanger block above the boom, is the arrangement of a loose roller or a block while maintaining the symmetry of the crane is no longer possible without further ado.

The demand for a loose role and a symmetry for both Pages would lead to a specially trained, very complex construction for attaching the role. That would

ο _

also additional weights come into the boom, which is adversely affect the mode of operation and the operating pressures.

Even with two mast cranes arranged next to each other, their loading ropes are connected to each other for coupled work, there are often difficulties in guiding the loading ropes,

In order to create perfect rope guidance for the loading rope, which easily adapts to the rope deflections, is according to the innovation provided that two eye plates are arranged symmetrically on the side of the boom head and one eye plate has a roller block with a loose roll, which can optionally be hung in each eye plate is.

The subject of the innovation is shown in the drawings. It show

The loading booms 2 are stored on the masts 1. The loading rope- 3 ".. ■ leads from the winch 4 via the mast block 5 to the boom head 6 and then to the loading hook 7. The hanger part. 8 consists of a hydraulic. ical adjustment device ,,. ■; . . '

On the boom head 6 of the loading boom 2 are shown in the Figo 2 to 4 symmetrically two eye plates 9 and. 10 arranged laterally. Each eye plate can optionally have a roller block 11 with a Take up loose roller 12, which is appropriately fastened by means of shackles 13 will. Depending on whether the crane is set up on port or starboard side of the ship, the loose roller 11, 12 in one or the other eye plate are shackled, so that both a coupled and normal work of the crane after "" is possible on both sides.

Each free eye plate 9 and 10 can be used to hold a Preventers 14 are used, to remove high torques and forces to keep out the slewing gear and the luffing gear of a crane. The boom is also advantageously guyed as soon as large loads are to be coupled to be driven »
