Definitions
- the invention relates to a telescopic boom, comprising a tubular base boom box and at least one boom box telescopically disposed within the base boom box, and a head having pulleys at the outboard end of the innermost boom box.
- the total weight of a mobile crane with a telescopic boom approved for use on public roads is determined by the permissible axle load (for example, 12 tonnes in Germany) and the number of axles. Parts of the crane, such as counterweight and main boom extension, often need to be transported separately to stay within allowable axle loads.
- the length of the telescopic boom which consists of rigid sheet metal boxes, limits the transport possibilities and the maximum permissible weight per unit.
- the last inner box so the innermost boom section, carries at the front end a head with a roller set for cutting the hoist rope, for the deflection of the hoisting rope (inlet roller) and possibly attachment points for a main boom extension and for a boom bracing.
- the head is built into the cross-section of the box and largely closes it by steel components and mounting parts that can not be removed except by complete disassembly of the inner box.
- the disadvantage is that you have to disassemble the innermost boom box, with the head arranged thereon and the associated set of rollers only, but can not continue to use the long boom, so that two boxes with the same cross section are needed for an extension. A box remains useless after the extra time.
- the invention has for its object to reduce the disassembly or assembly effort in a conversion of a boom to a longer boom and to avoid a remaining after the conversion and unnecessary at this point boom box.
- a telescopic boom crane with a tubular base boom box and at least one inner box, which is telescopically disposed within the Basisauslegerkastens, and a head with pulleys at the outside end of the innermost boom box characterized in that the functions of the head and the front storage at the end this innermost box are integrated into a frame which is arranged on the outer circumference of the boom box such that all parts belonging to the head outside the free cross section of the boom box are arranged and that for extension of the boom at least one further boom box is inserted into this box.
- At least one additional boom head can be fastened to the boom boxes to be inserted.
- the further boom head is attached to the innermost inner box.
- attachment points for a main boom extension are present at the innermost boom box to be inserted.
- the main boom extension can be a tilting auxiliary ejector or an adapter for a teetering auxiliary ejector.
- the head may have at least one inlet roller, which is pivotally, slidably mounted or mounted so arranged on the head that it does not affect the free cross section.
- the head (1) has at least one inlet roller, which is pivotally mounted, pushed or mounted so arranged on the head that it can be introduced into the free cross section by pivoting, pushing or mounting. It is advantageous if the head consists of interconnected cross connections.
- attachment points can be arranged for a boom bracing or it can be arranged as attachment points for a boom extension at the cross connections clevises.
- both head roller sets can be used for the shearing of a lower bottle.
- the head roller set of the inner boom box can serve as a cable guide and it is also possible that the boom head is releasably secured to the boom box.
- the invention is to integrate the functions of the head and a front bearing in a frame which is either permanently installed or mounted on the outer circumference of the inner boom box or other box, the cross section remains accessible without much retooling effort to insert more inner boxes without disassembly of the box to which the head is attached must make.
- FIG. 3 shows a corresponding arrangement with an inlet roller and FIG. 4 shows an end view for this purpose
- the head 1 consists of a load-bearing steel structure which is arranged completely outside the cross-section 2 of the jib box 3.
- the clevises 4, 5, as fastening points of a main boom extension, are arranged outside the box radii 6 and connected to each other horizontally and vertically by cross connections 7 and 8. At the same time they are connected in the longitudinal direction 9 with the box radii 6 to initiate the forces in the boom box 3.
- suspension points 10 are connected to the roller set 11, whose forces are introduced via the existing connections to the boom box 3.
- At the rear end of the upper fork heads 5 can each left and right a guy 12 for z. B. be arranged a lateral Auslegerabschreib whose forces are also introduced via the existing connections in the boom box 3.
- At least one inlet roller 13 is arranged for the roller set 11, which can also be displaced in width to minimize the deflection angle of the rope at different Einscherungen. If this inlet roller 13 protrudes into the cross section 2, it must be brought by pushing, turning or lifting out of the cross section in order to insert additional inner boxes can. It is also possible to arrange the inlet roller 13 outside of the cross section 2, so that they do not have to be removed from this.
- the sliding elements 14 take over the guidance and storage of the inner box 15 to be inserted, as is the case with telescopic jibs in the prior art.
- the cross connections 7.8 of the fork heads 4.5 stiffen the box cross-section 2, whereby bearing forces can be absorbed.
