Abstract

The invention provides a telescopic importing system and a crane with the same. The telescopic importing system provided by the invention comprises an importing mechanism, a traction mechanism and a supporting mechanism, wherein the importing mechanism comprising an importing transverse beam and an importing section movably arranged on the importing transverse beam; the importing transverse beam is detachably connected with a lower support seat; and the supporting mechanism comprises a supporting section which is arranged at the lower end of one horizontal end face of the importing transversebeam. The crane provided by the invention comprises the telescopic importing system. According to the telescopic importing system provided by the invention, a distance between the end part of the importing mechanism after importing is finished and a gyration centre is greatly reduced, a maximal elevation angle of a crane arm in a hoisting process is increased, a minimal gyration radius in the working process of a movable arm tower crane is reduced, a movable arm variable amplitude range is increased, a purpose of use convenience for hoisting operation is achieved, and the performances of the crane is improved. Furthermore, the telescopic importing system and the crane provided by the invention have good safety and stability, and easiness in operation.

Description

technical field [0001] The invention relates to the field of engineering machinery, and more specifically, to a retractable introduction system and a crane with the same. Background technique [0002] The tower crane needs to be lifted and introduced when increasing the height of the tower body. The introduction of the standard section requires a set of introduction system to complete. The introduction system is usually fixed on the tower body or the lower support. [0003] Such as figure 1 As shown, the introduction system is fixedly connected with the lower support 10' of the tower crane, and the introduction system generally includes an introduction beam 21', a tie rod 22' and a traction mechanism 23'. Due to the position of introduction and the needs of safe operation, the introduction beam 21 ' of the introduction system stretches out the distance L outside the tower body and must be long enough. However, the longer introduction beam is easy to interfere with the hois...
