Definitions

  • the invention relates to a tower crane according to the Preamble of the claim.
  • a well-known tower crane of this type meets the requirement of practice spend easily and quickly from its transport position to its operating position and vice versa quickly from the operating position back to its transport position to be able to fold up.
  • the well-known crane enables it to be erected quickly from the transport position in the operating position and vice versa folding into the transport position.
  • the boom In the known tower crane, the boom is in its respective swivel position opposite the tower is held by a rear guy rope that over rear guy supports are running. The angular position of the boom can therefore adjusted by pulling in or extending the guy rope become.
  • the object of the invention is to provide a simple angle adjustment of the boom enable.
  • Crane in its operating position Crane has a lower platform 1, which has fold-out supports 2 and with this connected foot pieces is supported on the ground.
  • the podium 1 With the podium 1 is connected via a rotary connection with the vertical axis of rotation of the superstructure 3.
  • the ballast weight 4 is located on a projecting part of the superstructure 3.
  • On an opposite, projecting part of the superstructure is around one Transverse axis articulated the lower tower section 5, the articulated with the upper tower section 6 is connected.
  • the boom link 7 is articulated to the top of the tower, which is articulated to the boom extension piece 8.
  • the Ausgerger-guy rope 9 In the field of articulated connection between the boom pieces 7 and 8 is the upper end the Ausgerger-guy rope 9 attached.
  • the boom guy rope runs over the guy support 10 and the A-frame over pulleys mounted on the uppercarriage 12, 13 to its fixed point 14 at the lower end of the hydraulic cylinder 15.
  • the tower is erected in the manner shown in FIGS. 3 to 5 through the hydraulic cylinder 15.
  • the lower tower section 5 and upper tower section 6 are connected to one another in an articulated manner by the laterally arranged joint 35.
  • the lever 36 is articulated in the joint 35, and in the joint 37 in the lower region of the upper tower section 6 is the Lever 38 hinged.
  • the levers 36 and 38 are one through the knee joint 39 Knee lever system connected.
  • the paired levers 35 are through a cross bar 40 connected to each other, to which the piston rod 41 of the cylinder 15 is articulated.
  • the lower end of the cylinder 15 is through the releasable hinge 42 connected to the lower tower section.
  • the tower sections 5, 6 stabilized in their extended position in that the connecting the tower pieces Joint 36 is laterally offset on the back of the tower and the Support the tower sections bluntly on their end faces. Because the tower from the boom is loaded by a right-hand rotating moment, the blunt on each other end faces of the tower sections do not stand out from one another. Of course can of course also on the side of the tower opposite the joint 36 a connection locking the two tower sections 5, 6 can be provided.
  • Fig. 4 shows the hydraulic cylinder 15 after erecting the tower.
