T'urrakochern was previously a normal · 'crane use ;. Au Be-IVlGK w-sr then a Krari permanently mounted on the stove required for maintenance work. The latter horseradish had to be mounted on top of the cooker after completion be in considerable trouble with rich brought, especially on cramped: construction, parts, on cones a moving crane only with considerable difficulty a.yetabar was.

Bsi the erection of structures of the type mentioned ^ using the method according to the invention and. one crane created to carry out the procedure? the above-mentioned and other disadvantages of known methods and devices can be avoided.

In a method of the type mentioned at the outset, it is in accordance with the invention provided that at each (Der Teilf.tücke at least one carrier or a profile part arranged, which or which a guide or rail for a forms on the sections along upwardly movable crane that one the girders or profile parts when building the Construction to form a continuous guide, which when each additional part is placed on top of each other: tückes P is extended, and that the crane is designed in such a way that he while erecting the structure on its outside able to climb upwards.

In an arrangement for performing the method according to the invention, the invention provides that one in the course of Erection of the structure on guide rails on the outside of the structure, a crane that can be moved upwards has a carriage carrying the crane, which via variable length lifting devices with a further, serving as a support carriage is connected, and that the two carriages by means of locking devices alternately lockable on the guide rails and alternately moved upwards by means of the lifting devices

The tower cooker 1 under construction is composed of a \ i. ^r ; oinor Ansah! Sections 2, to which I] -Pi ¹ OTiIe or the like serving as rails are welded; are. The crane 4, which has a boom 5, is mounted on a crane slide 6. The crane carriage 6 has an upper platform 7 supporting the crane 4 and a lower platform 7 ¹ supporting a winch arrangement 3. The carriage 6 is movably guided along the rails J by means of sliding shoes 9 engaging in the rails 3. The sliding shoes 9 can be locked on the rails 3.

Below the crane slide 6 there is a longer, separate slide 10 which serves as a support bearing and is connected to the crane slide via a pair of hydraulic jacks 12 composed of pistons and cylinders. The lower carriage 10 carries a Pumpensatκ 11 and v / eist sliding blocks 9 of the same kind as the carriage 6. The lifts 7 and 7 'are connected by a s a frame 14 laterally of the cooker 1 run the elevator car 13 to reach.

Starting from the position shown in the drawing, the construction of the construction by means of the arrangement according to the invention proceeds as follows: A section 2 for the cooker 1 is lifted into its position by means of the crane 4. In addition, the crane 4 can be rotated on its base 15, so that the new part 2 is placed on a previously placed part 2 ^! aufr: etzbar. When placing part 2, particular care must be taken that the rails J genpu have been aligned with one another. Subsequently, the section 2 with the

Previously added section 2 ^: welded. After the welding of the part 2 with the animal part 2 ^f , the H-profiles 5 form a ^{continuous guide that extends over the entire height of the KoChOx 1} S. Before you place the next part, the crane 4 must be moved upwards. The lower slide 10 is then locked in the position shown in the drawing, whereupon the locking of the crane element G is released Pressure medium device or an electromagnetic actuating device with stops, bores or the like on the guide rails 3 are brought into engagement. For this purpose, the locking devices are preferably arranged in or on the sliding shoes !: 9 To facilitate the laying of the cables and lines required for this purpose, a pressure medium source can be provided on each of the slides, whereby the operation of valves or the like for the pressure medium can be done electrically via a central control panel.

If the slide 10 is now locked on the rails 3 and the crane slide 6 is unlocked, the hydraulic jacks 12 are supplied with pressure by means of the pump set 11, so that the crane slide 6 lifts away from the lower slide 10. The jacks can be dimensioned so that the required lifting height can be achieved in one step, or in such a way that the crane is lifted in several steps. After lifting des.Kranschlitten 6 to the desired height, it is locked in the position it has reached. Then the lock of the carriage 10 can be released and. in the drawing corresponding JE · "but higher at a portion of 2 the position shown to be tightened by means of the jack in one of the. Subsequently, may be introduced a new lifting cycle. In order to avoid the risk that the locking devices of the crane carriage 6 and. the lower Slide 10 are released at the same time, safety devices are provided which the

After the construction of the tower cooker has been completed, the crane welded or otherwise attached to its upper end, where it can be used for later maintenance and repair work serves. Those that are no longer needed after the digester has been erected and are required for the crane to move upwards Facilities are dismantled and. can be reused when building other similar structures will. It is easy to see that the The method and the arrangement for its implementation are also advantageous when erecting tower cranes or the like Constructions are applicable.
