Abstract
The present invention relates to a crane, for example in the form of a tower crane, telescopic boom crane or port crane, comprising a load holding means which is hinged to a hoist rope and by means of which rope can be lifted and lowered, the load holding means having a rotary drive for rotating a load coupling part with respect to a rope hinge part hinged to said hoist rope about an upright load holding axis of rotation. According to the invention, the rotary drive is designed as an inertia drive and has a flywheel which is mounted on the load hook or load coupling part so as to be rotatable about the upright load holding axis of rotation and can be rotationally driven by a drive motor.
Claims22
A tower crane comprising:
- a load holder hinged to a hoist rope, wherein the load holder is configured to be lifted and lowered by the hoist rope, wherein the load holder comprises a rotary drive for rotating a load coupling part with respect to a rope hinge part hinged to the hoist rope about an upright hinge axis of rotation, wherein the rotary drive is configured to be an inertia drive and comprises a flywheel mounted on the load coupling part so as to be rotatable about the upright hinge axis of rotation and configured to be rotationally driven by a drive motor, wherein the rope hinge part has at least one deflection pulley for the hoist rope which is drivingly connected to an energy generator, wherein the crane is configured such that the energy generated by the energy generator during hoist rope movements is stored in an energy storage for supplying energy to the drive motor.
A tower crane, comprising:
- a load holder hinged to a hoist rope, wherein the load longer is configured to be lifted and lowered by the hoist rope, wherein the load holder comprises a rotary drive for rotating a load coupling part with respect to a rope hinge part hinged to the hoist rope about an upright hinge axis of rotation, wherein the rotary drive is configured to be an inertia drive and comprises a flywheel mounted on the load coupling part so as to be rotatable about the upright hinge axis of rotation and configured to be rotationally driven by a drive motor, wherein the load coupling part comprises a quick-coupler for coupling an end tool comprising a concrete bucket and/or load gripper in a rotationally fixed manner, wherein the quick-coupler comprises a form-fitting detachable locker for detachably locking the end tool to the load coupling part in a form-fitting manner, wherein the quick-coupler has an energy line coupling device and/or signal line coupling device for coupling an energy line and/or a signal line of the end tool to be coupled respectively for supplying energy to the end tool from the load holder and/or exchanging signals and/or information between the load holder and a respectively coupled end tool.
A tower crane, comprising:
- a load holder hinged to a hoist rope, wherein the load longer is configured to be lifted and lowered by the hoist rope, wherein the load holder comprises a rotary drive for rotating a load coupling part with respect to a rope hinge part hinged to the hoist rope about an upright hinge axis of rotation, wherein the rotary drive is configured to be an inertia drive and comprises a flywheel mounted on the load coupling part so as to be rotatable about the upright hinge axis of rotation and configured to be rotationally driven by a drive motor, wherein a control apparatus is configured to receive target posture information obtained from a construction data model (BIM) communicatively connected to the crane and, in dependence on the received target posture information, to control the rotary drive in such a way that the load coupling part and/or a end tool coupled thereto is moved into a position corresponding to a rotary position information.
