Abstract
A hoist includes a cable configured to lower and to raise a load, and a drum arranged to be rotatably seated about an axis of rotation and configured to wind up and to unwind the cable. The drum comprises a flanged wheel which comprises a securing device configured to secure the cable. The securing device comprises a cable-accommodating block comprising an abutment surface, and a cable clamp. The cable-accommodating block is affixed to the flanged wheel in a direction of tension of the cable and is configured to have the cable be passed there-through. The cable clamp comprises a counterpart abutment surface. The cable clamp is configured to be affixed to the cable. The abutment surface of the cable-accommodating block is configured to be contacted with the counterpart abutment surface of the cable clamp under an effect of a tensile force.
Claims18
A hoist comprising:
- a cable configured to lower and to raise a load;
- a drum arranged to be rotatably seated about an axis of rotation and configured to wind up and to unwind the cable, the drum comprising a flanged wheel which comprises a securing device configured to secure the cable, the securing device comprising:
- a cable-accommodating block comprising an abutment surface, the cable-accommodating block being affixed to the flanged wheel in a direction of tension of the cable and being configured to have the cable be passed there-through, and
- a cable clamp comprising a counterpart abutment surface, the cable clamp being configured to be affixed to the cable,
- wherein,
- the abutment surface of the cable-accommodating block is configured to be contacted with the counterpart abutment surface of the cable clamp under an effect of a tensile force;
- and
- an installation device configured to install and secure the cable clamp to the cable therein outside of the cable-accommodation block, the installation device comprising a support structure comprising:
- a receiving space for the cable clamp,
- a support surface configured to have the counterpart abutment surface of the cable clamp abut thereon, and
- a recess configured to have the cable be arranged therein,
- wherein,
- the installation device is arranged so that the installation device does not rotate with the drum, and
- when the cable clamp is in the receiving space and the cable is in the recess, the counterpart abutment surface of the cable clamp abuts the support surface in a plane which is perpendicular the direction of tension of the cable.
A hoist comprising:
- a cable configured to lower and to raise a load;
- a drum arranged to be rotatably seated about an axis of rotation and configured to wind up and to unwind the cable, the drum comprising a flanged wheel which comprises a securing device configured to secure the cable, the securing device comprising:
- a cable-accommodating block comprising an abutment surface, the cable-accommodating block being affixed to the flanged wheel in a direction of tension of the cable and being configured to have the cable be passed there-through, and
- a cable clamp configured to be affixed to the cable, the cable clamp comprising a counterpart abutment surface, an exterior cone ring comprising an exterior cone ring surface, and an interior cone ring, the interior cone ring comprising,
- an interior cone ring cone surface, the interior cone ring being arranged so that the interior cone ring cone surface converges toward the load, and
- a plurality of segments which are arranged separate from each other substantially parallel to the direction of tension of the cable,
- the interior cone ring being configured to surround the cable and to be connectable to the exterior cone ring so that the interior cone ring is connectable with the cable in a force-locking manner in the direction of tension of the cable,
- wherein,
- the interior cone ring is surrounded by the exterior cone ring,
- the plurality of segments of the interior cone ring are arranged to comprise a segment cone surface,
- the exterior cone ring surface is constructed complementary to the segment cone surface, and
- the abutment surface of the cable-accommodating block is configured to be contacted with the counterpart abutment surface of the cable clamp under an effect of a tensile force.
