Embodiment Construction

[0040] figure 1 Through 4 are detailed views of one embodiment of the slider provided by the present invention and perspective views of individual parts. The slider consists of two parts, the thrust wedge 1 ( figure 1 with 2) and sliding part 5 (Figures 3 and 4). The thrust wedge 1 has a wedge surface 2 and a bearing surface 3 . The thrust wedge 1 also has securing means 4, in this example in the form of recessed eyelets, as structures for cooperating pretensioning means, which will be described in more detail below. The sliding part 5 shown in Figures 3 and 4 constitutes a supplementary part to the thrust wedge 1, the sliding part 5 has a sliding surface 6 on its outside and a wedge surface 7 on its inner surface, when these parts are in an assembled state, the wedge surface 7 and The wedge faces 2 of the thrust wedge are in contact and act together. The sliding part 5 also has a groove 8 . A part of the pretensioning device is then packed into the groove 8 and the groo...

Abstract

The invention relates to a slide block for a telescopic crane jib which includes at least two mutually co-operating and relatively movable slide block parts, at least one of the parts comprising an oblique surface. The parts of the block are pre-tensioned or biased to move in a direction so that the total width of the slide block will vary and enlarge to fill a gap between inner and outer telescopic jib sections. In a telescopic crane jib-slide block arrangement incorporating such a slide block, the slide block is disposed on an inner telescopic jib section and presents a sliding surface to an adjacent outer telescopic part.

Description

technical field [0001] The invention relates to a slider of a telescopic boom and a slider assembly (arrangement) of a telescopic boom. In particular, the present invention relates to a self-adjusting slide, that is, a slide that can adapt its width to its environment and needs within its assembly in or on a telescopic arm, thereby optimally meeting its Task. Background technique [0002] The term "slider assembly" as used in this context refers to the parts of the slider itself, as well as those parts of the telescoping arm which cooperate with the slider to ensure its function. [0003] The purpose of providing sliders in the telescopic arms is to enable the telescoping motion of the telescoping parts relative to each other with as little friction loss as possible, thereby minimizing wear on the telescoping parts themselves. Generally, they are simply inserted between the telescoping parts and are usually fixed to one telescoping part, either the outer one or the inner o...
