Definitions

  • the present invention relates to a crane having the features of the preamble of claim 1.
  • hose run Many different solutions for realizing the course of the at least one hose line (hereinafter also referred to as "hose run") in the region of the transition from the crane column to the first crane arm are known in the prior art.
  • a solution according to the prior art is in document FR8201499 disclosed.
  • the hose path between the crane column and the first crane arm takes place from a connection point mounted on the outside of the crane column to a connection point arranged on an outer side of the first crane arm.
  • connection point on the crane column is located on the side of the crane column facing away from the first crane arm.
  • the course of the hose takes place on the outside of the crane pillar via the first joint to a connection point located at the top of the first crane arm and / or the at least one hose line passes laterally in the lower region of the first joint and then runs upward to one the underside of the first crane arm arranged connection point.
  • the object of the invention is to reduce the risk of damage to the at least one hose line in a generic crane.
  • the crane has a crane column which is arranged rotatably about a vertical axis on a base frame and a first crane arm which is mounted pivotably on the crane column via a first joint.
  • At least one hose leads from a first connection point on the crane column or the base frame to a second connection point in or on a region of the first crane arm which is close to the first joint.
  • Due to the selected hose path results in a compact and tight leadership of at least one hose between the crane column and the first crane arm.
  • the first crane arm is often referred to as the main or lifting arm and the second crane arm as articulated.
  • the second crane arm may carry one or more telescopic boom extensions.
  • FIG. 1 shows a crane 1 with a base frame 2, a crane column 3, a first crane arm 4, a second crane arm 5 and a telescopic mounted in the second crane arm boom extension 6, which opens into a load hanger 7.
  • the first crane arm 4 is pivotally mounted on the crane column 3 via a first joint 8. The pivoting takes place via a first piston-cylinder unit 10.
  • the second crane arm 5 is pivotally mounted on the first crane arm 4 via a second joint 9. The pivoting takes place via a second piston-cylinder unit 11.
  • the crane column 3 is rotatably mounted about a vertical axis on the base frame 2.
  • the base frame 2 is often mounted on a vehicle. However, it could also be mounted stationary.
  • a first embodiment of the invention is in the FIG. 2 shown.
  • FIG. 2a shows the in FIG. 1 illustrated crane 1 in a detailed view of the area of the crane column 3 and the first crane arm 4 in section.
  • a hose line 12 (shown here and in the following embodiments representative of several hose lines, normally a single hose line will not suffice) extends between a first connection point 13 at the crane column 3 and a second connection point 14 in the first crane arm 4. Pipes 15 lead from the connection points 13, 14 away.
  • the hose 12 enters via an opening 18 in the first crane arm 4 a.
  • the second connection point 15 is located below a service opening 16 of the first crane arm 4 arranged in the first crane arm 4, which permits easy and quick access to the second connection point 14 and is usually covered by a cover 18 arranged detachably on the first crane arm 4.
  • a roller 17 or a sliding section can be arranged on the first crane arm 4.
  • the second connection point 14 is farther away from the service opening 16 in the interior of the first crane arm 4, specifically in the region of the upper side of the first crane arm 4.
  • FIG. 5 is the second connection point 14 as in FIG. 4 further away from the service opening 16 in the interior of the first crane arm 4, specifically in the region of the underside of the first crane arm 4. This also applies to the exemplary embodiment of FIG. 6 ,
  • the second connection point 14 may be arranged near the first articulation 8 in or on the first crane arm 4.
  • the FIG. 7 shows that the second connection point 14 can also be arranged at a distance from the first joint 8 in or on the first crane arm 4.
