Abstract

Swing member cable siding, especially for powering cranes, including an arm whose lower end is placed on the movable parts of the crane, and the upper end produces motion elements of the cable siding, which is lower the end of the arm mounted on the shaft, firmly connected with moving crane parts, using premium, for example, ball joints, wherein on the moving part of the crane is arranged relative safety switch by moving the arm relative to the moving part crane.

Description

The invention relates to a cable siding rake member, in particular for powering cranes, comprising an arm whose lower end is supported on a movable part of a crane and the upper end causes movement of the cable siding elements.

Retracting and unfolding of cables laid on cable sidings is carried out by means of an arm firmly anchored to the moving part of the crane. If the rider or the guide rails of the cable siding fails, this rigid coupling will damage the cable siding or tear the cables, usually into the work area, which seriously compromises the safety of work.

These drawbacks are largely overcome by a cable sidding member, in particular for powering cranes, comprising an arm whose lower end is supported on a movable part of a crane, for example, and the upper end induces movement of the cable siding elements according to the invention. The arms are mounted on a shaft rigidly connected to the movable part of, for example, a crane, by means of a safety, eg ball coupling, wherein a safety switch is arranged on the movable part of for example a crane, rejuvenated by relative movement of the arm relative to the movable part.

The arrangement of the scraper member according to the invention guarantees a virtually instantaneous stopping of the crane in the event of a breakdown occurring on the cable siding, thereby significantly increasing the safety of work in the work area and eliminating both direct and consequential damage resulting from a possible accident.

An advantageous embodiment consists in that the ball coupling is formed on the shaft by a freely rotatable and axially secured hub fixedly connected to the lower end of the arm, where through the axle bore there are arranged through axial bores for bearing the ball pressed by springs. recesses formed in a disc that is rotatably mounted on the shaft.

It is furthermore advantageous if the arm is adjustable in length.

A particular embodiment of the folding member according to the invention is shown in the accompanying drawings, in which Fig. 1 is an overall view of the folding member, Fig. 2 shows a detail of the ball coupling and Fig. 3 shows a section A-A of Fig. 2.

The rake member 15 of the cable spreader 15 forms an arm 1 whose upper end 2 implies the movement of the sliders 16 of the cable spreader 15 and the lower end 2 is mounted on the shaft 4. The shaft 4 is fixedly attached to the movable part 16, e.g. The actual bearing of the lower end 2 on the shaft 4 forms a ball coupling 6. The ball coupler 6 is freely rotatably mounted on the shaft 4 and a hub 8 axially secured by a retaining ring 17, in which axial through bores are formed ⁱⁿ which the balls 10 are pressed by springs 11 into corresponding recesses 14 formed in a disc 13 fixedly mounted on the shaft. . The spring pressure 11 is regulated by screws 12. Further, a safety switch 2 controlled by the relative movement of the arm 1 relative to the movable part 2, e.g. crane.

If the slider 16 or the guide rails 18 of the cable siding fails to increase the tensile force in the arm 1, the axial force of the balls 10 overcomes the pressure of the springs 11, thereby rotating the arm 1 relative to the movable part 5, e.g. The swinging of the arm 1 then causes the crane to stop by means of the safety switch 7.
