Definitions
- the invention relates to an auxiliary device for setting the lower and upper luffing support of an adjustable Hilfsaumikers, which is arranged at the head of the main boom of a mobile crane, and a method for setting.
- the lower luffing support is lifted by an additional crane and parked on a pole.
- the crane operator must then walk along this raised rocker support to unhook the lifting gear of the auxiliary crane. This operation is not without risk, because the rocking support in the raised position can be up to 6 m above the ground.
- the actual upgrade process which is carried out by the crane to be erected, can be continued.
- the disassembly must be carried out in the reverse manner, d. H. the lower luffing support is placed on a pole by the crane to be equipped, the crane operator hangs the lifting lugs of the additional crane after hitting the lower luffing support and raises the lower luffing support briefly, so that the rod is free. The rod is then guided parallel to the lowering of the lower luffing support via a rope by hand, so that it is deposited together with the lower luffing support back into transport position.
- the object of the invention is therefore to provide a way by which a faster and safe up and disassembly of adjustable Hilfsauslegem can be achieved. This object is achieved with the features of claim 1, as well as the method of preparing according to claims 14,15 and 16.
- the adjustable Hilfsauêter 3 is, for example via an adapter 4 to the head 6 of the
- Main boom 5 cultivated, whereby however the adapter is not absolutely necessary for the accomplishment of the task. Cultivation is carried out by means suitable for use, e.g. Auxiliary crane or
- the hoist rope 14 is unwound from the Haupthubtechnik 15 of the mobile crane and with the
- Both luffing posts are interconnected by a tension member strand 17 ( Figure 2).
- the connecting rod 13 is connected to the flying cross member 11 (Fig. 3).
- the hoist rope 14 is unwound, the cross member 11 is aligned along a line from the fixed cross member 12 to the tip 18 of the lower rocker support 9. The pulley 19 is stretched. The hoist rope 14 can be decoupled from the Verbindunsstange 13 in this position. 4, the next step is shown.
- the main boom 5 is raised above the luffing cylinder 7.
- the Verstellhubwerk 16 is unwound, so that the distance between the flying crosshead 11 and fixed cross member 12 increases.
- the Verstellhubwerk 16 can be wound up again from a predetermined main boom angle position, so that the distance between the flying traverse 11 and fixed crossbar 12 is reduced.
- the adjustable Hilfsaumiker 3 lifts off the ground, since it is connected by means of another Switzerlandgliedstranges 10 with the upper rocker support 8 (Fig. 5).
- the adjustable Hilfsaudunger 3 is mounted on an adapter 4 to the head of the main boom 5 (the adapter is not absolutely necessary for the fulfillment of the task).
- the cultivation takes place by suitable aids, z. B. auxiliary crane or forklift.
- the two rocker supports 8 and 9 are flat for reasons of transport on the Hilfsauêter 3.
- the hoisting rope 14 is unwound from the main lifting gear 15 of the mobile crane and connected to the multi-link rod assembly 13. This strand is permanently connected to the lower rocker support 9. Both rocker supports are interconnected by a tension member strand 17.
- the Aufstellbock 20 By winding the hoisting rope 14 on the hoist 15, the Aufstellbock 20 begins to erect itself, the connecting rod strand 13 begins to stretch to the right of the Aufstellbock 20, then also left from Aufstellbock 20 until the lower rocker support 9 is raised.
- the main hitch 15 continues to wind, the traction member strand 17 between the rocker supports 8 and 9 begins to tension.
- the jack 20 is prevented in its position to the rear by the stop screws on falling back.
- FIG. 9 The connecting rod strand 13 has arrived in its final position in front of the Haupthubtechnik 15, the rocker supports 8 and 9 are in the end position, the operation is completed.
- the disarming takes place in reverse order.
- This figure shows an embodiment of the jack 20, and that consists of a welded construction which is rotatably mounted (pivotable) on the lower rocker support. At the bearing feet stop means are provided which prevent a turning of the jack. At the upper end of the Aufstellbockes is a fork in which the previously described connecting rod strand 13 - as can be seen from Figures 6 to 9 - can be stored.
- the stop screws are used during disassembly also at the same time that the jack 20 is fixed in its position such that the connecting rod strand 13 is taken over the fork shape of the jack 20 again.
- This connecting rod strand 13 pulls the Aufstellbock 20 when upgrading the tiltable Hilfsaumikers with high until it comes to rest on the stop means.- Accordingly, when dismantling the Aufstellbock 20 by the discharge of the connecting rod strand 13 taken and brought into its transport position ( Figure 6).
