Embodiment Construction

[0020] reference figure 1 , It shows the hoisting device of a rope hoist (for example, in an overhead crane trolley not shown), which includes a rope drum 1 for hoisting rope 2 and a hoisting device (not shown) Lifting member 3. The lifting member 3 has a wheel device 4 for lifting the rope 2. Correspondingly, the higher part of the fixed section of the rope hoist (such as its frame) has sheaves 5 for hoisting the rope 2. The hoisting rope 2 is routed from the rope groove 1 a on the rope drum 1 to a fixed attachment point X on the rope hoist via the rope wheel device 4 and the sheave 5 for said hoisting member 3. This uses a single hoisting rope 2 to form a four-rope or 1x4 hoisting rope arrangement according to the drawings, which includes four pitches in the up and down direction. When the lifting member 3 is lowered, the lifting member 3 moves a distance S / i to one side. The rope drum 1 is in a horizontal position. The hoisting rope 2 is in a layer on the rope drum 1.

Abstract

The invention relates to the hoisting arrangement of a rope hoist that comprises the hoisting rope (2), rope drum (1) with one rope groove (la) for the hoisting rope, and a hoisting member (3) for hoisting a load, which hoisting member comprises a rope pulley arrangement (4) for the hoisting rope (2), where the hoisting rope (2) is routed from the rope drum (1) via at least the hoisting member's (3) rope pulley arrangement (4) to a fixed attachment point (X) on the rope hoist. The rope drum (1) is tilted in relation to the horizontal plane in a manner where the first end of the rope drum (1),towards which the hoisting rope (2) is wound in the hoisting member's (3) upper position, is higher than the rope drum's (1) second end, towards which the hoisting rope (2) is unwound in the hoistingmember's (3) lower position.

Description

Technical field [0001] The present invention relates to a hoisting device for a rope hoist, which includes a hoisting rope, a rope drum having a rope groove for the hoisting rope, and a hoisting member for lifting a load, the hoisting member including a hoisting rope for the hoisting rope The rope sheave device of, wherein the hoisting rope is routed from the rope drum to a fixed attachment point on the rope hoist via at least the rope sheave device of the hoisting member. Background technique [0002] Generally, such a lifting device of a rope hoist may be present in the trolley of an overhead crane (which has been arranged to move along, for example, a horizontal main support device). Among them, the design basis for such equipment has been clarified in the FEM standard (Federation Europeenne dela Manutention, 1.001, manual 4). [0003] In such a device, an angle is formed between the rope groove on the rope drum and the exit direction of the hoisting rope, because when the hois...
