Abstract
A lifting assembly for a lift truck with a lifting mast having at least one mast frame and a load part, as well as a lift drive having at least one lifting chain that lifts the mast frame, is attached to the mast frame at a connecting point and is guided across a deflection point. The lifting assembly includes at least one tensioning component that is arranged on the mast frame between the connecting point and deflection point of the lifting chain.
Claims19
A lifting assembly for a lift truck, the lifting assembly comprising:
- a lifting mast comprising a plurality of mast frames mounted and guided in each other;
- a load part;
- a lift drive comprising at least one lifting chain attached to a first mast frame of the plurality of mast frames at a connecting point on the first mast frame and guided across a chain roller on another mast frame;
- and
- a tensioning component located on the first mast frame between the connecting point and the chain roller, the tensioning component configured to apply tension on the lifting chain and deflect the lifting chain out of a direct connecting line between the connecting point and a deflection point defined by the chain roller;
- wherein the tensioning component comprises a shape of a block and being located at approximately half the distance between the connecting and deflection points when the first mast frame is in a retracted state;
- wherein the tensioning component engages the lifting chain in the retracted state and disengages the lifting chain in an extended state.
A lift truck comprising:
- a lifting assembly comprising:
- a lifting mast comprising a plurality of mast frames mounted and guided in each other;
- a load part;
- a lift drive comprising at least one lifting chain attached to a first mast frame of the plurality of mast frames at a connecting point on the first mast frame and guided across a chain roller on another mast frame;
- and
- a tensioning component located on the first mast frame between the connecting point and the chain roller, the tensioning component configured to apply tension on the lifting chain and deflect the lifting chain out of a direct connecting line between the connecting point and a deflection point defined by the chain roller;
- wherein the tensioning component comprises a shape of a block and being locate at approximately half the distance between the connecting and deflection points when the first mast frame is in a retracted state;
- wherein the tensioning component engages the lifting chain in the retracted state and disengages the lifting chain in an extended state.
