Description

The invention relates to a crane system, in particular a bridge crane system, with at least one horizontally extending and on or at a distance parallel to each other arranged tracks movable crane girder on which a crane trolley is arranged movable with a hoist.

Essentially, overhead crane systems consist of two crane girders with headrests that can be moved on parallel tracks. Along the crane girder a run or crane trolley is arranged movable. In general, the tracks and crane girders are made of double-T profiles, at the end factory connecting flanges are mounted with holes, which can be confined in the final assembly on site with corresponding pads. The parallel tracks are connected by stands to the ground, with the height of the stand depends on the one hand according to the height of the installation site and on the other hand according to the size of the loads to be lifted.

Such cranes are installed, for example, in nacelles, production and assembly halls, the stand for anchoring the rails of the bridge crane are firmly anchored to the ground at the site, for example by screwing with special foundations.

They are not only used for moving loads, for example in the form of workpieces and raw materials inside and outside of halls, but also in particular in warehouses for the operation of warehouses (automated warehouse operation).

From the DE 295 02 958 U1 a bridge crane with a movable on two rails bridge, a lifting device for lifting an elongated lifting frame is known, which serves to receive an elongated load, the lifting frame in two vertically aligned, attached to the lateral edge regions of the bridge Hubrahmenführungen stored so that it against a tilting is secured from its vertical position, wherein the lifting frame a horizontal synchronizing shaft is provided, which is mounted in the lifting frame and is in each case a gear in a vertically arranged on Hubrahmenführung rack engaged.

From the DE 10 2014 109 146 A1 is a crane system for transporting and possibly lifting and lowering of loads, at least consisting of a fixed to support crane longitudinal profile and along the Kranlängsprofils displaceable chassis with means for receiving or holding loads known, the displacement of the chassis along the Kranlängsprofils by means of an electric motor drive he follows. In addition, the invention relates to a crane system for transporting and possibly lifting and lowering of loads, consisting of a displaceable on parallel spaced transverse beams crane longitudinal profile and along the Kranlängsprofils movable chassis with means for receiving or holding loads, wherein the displacement of the chassis along the Kranlängsprofils and the displacement of the Kranlängsprofils entlag the parallel cross member by means of electric motor drives takes place.

The DE 10 2011 103 593 A1 describes a crane system for transporting and optionally lifting and lowering of loads, at least consisting of a bearing on or preferably indirectly to a support forming building sections attachable crane section, in particular crane longitudinal profile and a movable in the crane profile along the crane profile by means of casters suspension with means for receiving or holding loads, wherein on or in the crane profile further profile or surface parts are arranged, which form the running surface for the wheels of the chassis.

In bridge crane systems, it is necessary because of the predetermined distance between the parallel tracks for the head support of the crane girder or crane bridge to carefully match the effective length of the main girder of the crane bridge to the corresponding distance of the connections of the headgear. If the dimensions are not exactly maintained, it can lead to high transverse loads of the head carrier and its chassis while driving.

In view of the required care in the production in terms of dimensional accuracy of the construction of the crane systems at the customer preferably by specialists of the manufacturer, since the main carrier and also on the bridge girder usually welding must be made.

Furthermore, before building the bridge crane to create appropriate foundations on which then the stand is placed.

Based on the known prior art, the object of the invention is to provide a bridge crane, which is assembled in a modular system, can be easily and quickly mounted by non-professionals after delivery by the manufacturer and manages without complex foundations and anchoring in the subsoil.

According to the invention the object is achieved by a crane system, in particular a bridge crane system, with the features of claim 1. In the subclaims advantageous embodiments of the invention are given.

The crane system according to the invention is constructed as a modular system. The corresponding basic framework of the crane system consists of the vertical columns with pushed-on universal heads, the raceways and the cross members. In the parallel arranged raceways of the bridge girder with its attached to the ends chassis supports is arranged movable. On the bridge girder itself a movable trolley with a hoist is provided.

Runway, cross member and bridge girders are preferably made of a low-wear aluminum lightweight profile. The aluminum lightweight profile for the raceways has a wear-resistant insert on which roll the wheels of the chassis carrier. Furthermore, the aluminum profile has inside and / or outside conductor rails.

The floor facing the ends of the pedestals are provided with so-called counterweights. The counterweights, which are formed as moldings with the necessary statically determined weight, stand on the base plates of the pillars and enclose them.

By using anti-slip mats under the foot plates in conjunction with the counterweights, can be dispensed with a firm connection (anchoring) with the substrate.

The invention is thus based on the idea of manufacturing the crane installation according to the invention, in particular designed as a bridge crane installation, according to the modular principle, whereby the crane installation can be expanded by simple conversion or installation.

Since these cranes do not necessarily have to be fixedly connected to the ground, they are preferably suitable for a limited period of use at the site. The use of the universal heads on the pillars is especially special. These can on the one hand from a receiving plate with attached thereto side parts with longitudinal holes, which can be displaced on the upright columns and bolted via the holes arranged in the grid system exist.

On the other hand, the universal heads can also be designed such that they consist of an attachable to the upper end of the pedestal and verklemmbaren with this head part, above the formed of two clamping shells Aufsteckteils are provided at right angles to each other arranged profile receptacles for the raceways and the cross member.

To adjust the track and the cross member on the pillars, the universal heads can be moved on the pillars and clamped after setting on this.
