Definitions
- the invention relates to methods for switching the hoisting rope of a crane from single-stranded operation to double-stranded operation and from double-stranded operation to three-stranded operation and devices for carrying out this method.
- Hubseilumscherscherungen serve to change the strand number.
- An increase in the number of strings reduces the power requirement, but at the same time also reduce the working speeds. It is therefore advantageous if the hoist rope strand number can be changed as needed.
- there is a need for a Umschervorraum which makes it possible to effect a change in the strand number with only a few steps and little effort.
- DE 603 18 518 T2 describes a device for changing the number of rows of a pulley for a crane, which makes it possible to carry out a change in the hoist rope strand number of the pulley from a pulley with a single strand in a pulley with two strands and vice versa, in which no disassembly of the pulley is required.
- the boom In this device, the boom must first be brought to change the strand number in a horizontal position. Since the bottom block is not held by the hoist rope during the change, because one end of which is released by hand, the bottom block is to be secured, which is done by attaching it to a bracket adjoining the bracket by means of a bolt.
- the hoist rope is given "play", the Bolt that connects the hoist rope at one end via a wedge with the swivel, which is located at the fork tip of the boom shaft, is released. Subsequently, a connection of the wedge piece at the now free end of the rope with the lower block, which has through holes for this purpose, is produced via a bolt. With a locked, inwardly curved guide which rests approximately tangentially to the rope pulley of the lower block, the single strand of the hoist rope is guided at the point where it moves away from the pulley to the center of the upper part of the housing of the pulley on the boom.
