Abstract
The present invention relates to a method for suspending the rails, tracks, or the like of a lifting apparatus on a beam, with at least one cable that connects the beam and the tracks, the ends of the cable being connected to each other by a connector, so as to be releasable. In order to prevent the redundancy suspension system parting and falling, or the cable being damaged by the cable clamps, in the event of a sudden load, for example if the rail attachments break, it is proposed that the connector (10) consist of two wedge locks (12, 13) that can be joined to each other to form one structural element, these wedge locks being arranged in such a manner that the one wedge lock (12) be rotated through 180°
relative to the other wedge lock (13). Thus, the effective directions of the wedges (18 close, 19) that clamp the cable ends (9a, 9b) are opposed to each other. The cable ends (9a, 9b) that enter from opposite directions can be returned in the direction opposite to their direction of entry after passing around the wedges (18, 19) of the wedge locks (12, 13), and they can be clamped by the wedges (18, 19), at least when under load.

Description
A System for Suspendinq the Ralls or the Llke of a Llftlng Apparatus on a Beam The present inventlon relates to a system for suspendlng the ralls, tracks, or the llke of a llftlng apparatus on a beam.
A brochure publlshed by Demag Materlal Handllng Equlpment descrlbes a redundancy suspension system for rails (crane tracks and monorall systems) ln whlch the ralls are addltlonally secured by means of a steel cable. It ls the task of a redundancy suspenslon system to assume the supporting function should the actual suspenslon system that ls usually ln the form of a bolted connectlon fall. To thls end, the steel cable ls wrapped around the upper beam and passed through the opening of a supportlng element that ls addltlonally secured to the ralls. The ends of the cable are formed as thimbles that connect the ends of the cable securely to each other, so that the cable ltself forms a closed rlng.
One disadvantage of this solutlon ls that ln the event of abrupt loadlng, for example, lf a rall attachment should fall, the redundancy suspension system also fails or, at the least, the cables become damaged by the cable clamps.
It is the task of the present lnvention to descrlbe a cable connector for a redundancy suspenslon system, wlth which the disadvantages discussed above are avoided.
Accordlng to a broad aspect, the invention provides a connector for releasably connecting a cable having two cable ends . This connector conslsts of two wedge locks that are iolned to each other to form one structural unlt, these belng arranged in such a way that the one wedge lock ls rotated through 180~ relatlve to the other wedge lock, so that after passing around the wedges of the wedge locks the cable ends that enter from opposing directions can be returned in the direction that is opposite the direction in which they entered, can be clamped by the wedges at least when under load, and are thus opposed to the effective directions of the wedges that clamp the ends of the cable. This ensures that if an sudden load occurs, the cable pulls tight against the fictional resistance of the wedge locks, which then become hot and absorb the kinetic energy that is generated suddenly.
One advantageous embodiment of the connector is such that each wedge lock is formed from a base plate and a pocket plate that is installed on this and lncorporates a wedge-shaped space to accommodate the correspondlng insertable wedge.
It is advantageous if the wedge can move freely in the direction of entry so that the wedge cable connector is simple to release when not under load.
A simply constructed connector consists of two plates that have a common base plate as the connector.
In order to prevent the cable from slipping out, the end of the cable is preferably fitted with a cable clamp.
In order to provlde for the effective absorption of the kinetic energy in the event of a sudden load, preferably the angle of the wedge lies in the range from 10~ to 16~.
One embodiment of the present invention will be described in greater detail below on the basis of the drawings appended hereto. These drawlngs show the following:
Figure 1: a cross section through a beam with a redundancy suspension system;
Figure 2: a front view of the suspension system shown in Figure 1:
Figure 3: a front vlew of a connector;
Flgure 4 a plan vlew of the connector shown ln Flgure 3, wlth the steel cables that pass through this, shown ln cross section.
Figure 1 shows the suspenslon of a track 1 on a beam 2 by means a pin 3 that is connected at its upper end to a cross beam 4 so as to be able to pivot through a small angular range.
The cross beam 4 ls connected securely through a bolted connectlon 5 to the lower flange 6 of the I-beam 2. The upper contact surface 7 of the cross beam 4 lles against the lower outer surface 8 of the flange, acted upon by a force.
As can be seen ln Flgure 1, the lower end of the pin 3 is also secured to the track 1 and can also pivot through a llmited angular range.
Flgure 1 also shows that a cable 9 is provided with the pln 3 for suspenslon, and the beam 2 and the track 1 are connected to each other by thls cable. To thls end, the cable passes around the beam 2 and through the suspension of the track 1. The ends of the cable 9 are connected securely to each other so that the cable 9 forms a closed rlng that holds the track 1 on the beam 2 should the suspenslon system fail.
The ends 9a, 9b of the cable are connected tightly to each other by means of a connector 10. The connector 10 can be seen more clearly in plan view in Figure 3 and Figure 4 (plan vlew). It comprises a base plate 11 that has as a wedge lock 12, 13 on each side. The two wedge locks 12, 13 are connected slmultaneously to each other by way of the base plate 11. Each wedge lock thus consists of the common base plate 11 and a pocket plate 14, 15 that is formed from sheet metal and secured to it. The wedge locks are rotated through 180~ relative to each other; the upper openlng 16 of the wedge lock 12 and the lower opening 17 of the wedge lock 13 can both be seen in the plan view ln Flgure 4. The lnterlor spaces of the pocket plates 14, 15 are in the shape of a wedge and each has two slde surfaces and, when produced, these subtend an acute angle referred to as the wedge angle. In the embodlment shown, the wedge angle is 14~. A correspondingly shaped wedge 18, 19 can be inserted into the pocket plate from one slde, and thls wedge forms essentlally the same wedge angle. As can be seen in Figure 3, the ends of the cable enter the wedge-shaped pocket plate from opposite directlons and then pass around the wedge. The wedge 18, 19 can be moved freely in at least the direction of entry.
In some sections, transversely to its longitudinal direction and on both sides of its outside periphery, the cable lies against the wedge and the inside surface of the pocket plate; after passlng around the wedges 18, 19 of the wedge locks 12, 13, it returns in the direction that is opposite to its dlrectlon of entry. The cable 9 can be clamped by the wedges 18, 19, at least when lt is under load.
The effectlve directions of the wedges 18, 19 that clamp the cable ends 9a, 9b thus act in opposlte dlrectlons. Cable clamps 20a, 20b are used to secure the cable ends 9a, 9b, as ls shown ln Figure 1.

One embodiment of the present invention will be described in greater detail below on the basis of the drawings appended hereto. These drawlngs show the following:
Figure 1: a cross section through a beam with a redundancy suspension system;
Figure 2: a front view of the suspension system shown in Figure 1:
Figure 3: a front vlew of a connector;
Flgure 4 a plan vlew of the connector shown ln Flgure 3, wlth the steel cables that pass through this, shown ln cross section.
Figure 1 shows the suspenslon of a track 1 on a beam 2 by means a pin 3 that is connected at its upper end to a cross beam 4 so as to be able to pivot through a small angular range.
The cross beam 4 ls connected securely through a bolted connectlon 5 to the lower flange 6 of the I-beam 2. The upper contact surface 7 of the cross beam 4 lles against the lower outer surface 8 of the flange, acted upon by a force.
As can be seen ln Flgure 1, the lower end of the pin 3 is also secured to the track 1 and can also pivot through a llmited angular range.
Flgure 1 also shows that a cable 9 is provided with the pln 3 for suspenslon, and the beam 2 and the track 1 are connected to each other by thls cable. To thls end, the cable passes around the beam 2 and through the suspension of the track 1. The ends of the cable 9 are connected securely to each other so that the cable 9 forms a closed rlng that holds the track 1 on the beam 2 should the suspenslon system fail.
The ends 9a, 9b of the cable are connected tightly to each other by means of a connector 10. The connector 10 can be seen more clearly in plan view in Figure 3 and Figure 4 (plan vlew). It comprises a base plate 11 that has as a wedge lock 12, 13 on each side. The two wedge locks 12, 13 are connected slmultaneously to each other by way of the base plate 11. Each wedge lock thus consists of the common base plate 11 and a pocket plate 14, 15 that is formed from sheet metal and secured to it. The wedge locks are rotated through 180~ relative to each other; the upper openlng 16 of the wedge lock 12 and the lower opening 17 of the wedge lock 13 can both be seen in the plan view ln Flgure 4. The lnterlor spaces of the pocket plates 14, 15 are in the shape of a wedge and each has two slde surfaces and, when produced, these subtend an acute angle referred to as the wedge angle. In the embodlment shown, the wedge angle is 14~. A correspondingly shaped wedge 18, 19 can be inserted into the pocket plate from one slde, and thls wedge forms essentlally the same wedge angle. As can be seen in Figure 3, the ends of the cable enter the wedge-shaped pocket plate from opposite directlons and then pass around the wedge. The wedge 18, 19 can be moved freely in at least the direction of entry.
In some sections, transversely to its longitudinal direction and on both sides of its outside periphery, the cable lies against the wedge and the inside surface of the pocket plate; after passlng around the wedges 18, 19 of the wedge locks 12, 13, it returns in the direction that is opposite to its dlrectlon of entry. The cable 9 can be clamped by the wedges 18, 19, at least when lt is under load.
The effectlve directions of the wedges 18, 19 that clamp the cable ends 9a, 9b thus act in opposlte dlrectlons. Cable clamps 20a, 20b are used to secure the cable ends 9a, 9b, as ls shown ln Figure 1.
