Abstract

The invention relates to a crane. The crane comprises a vehicle body, a main arm (1) and an auxiliary arm (2), wherein the main arm (1) can rotate to a position where the main arm (1) is horizontallyplaced on the vehicle body; and the auxiliary arm (2) is connected with the end, away from the vehicle body, of the main arm (1), and can be overturned to the position above the main arm (1) horizontally placed on the vehicle body. By applying the technical scheme, the auxiliary arm of the crane can be overturned to be above the main arm, the problem that when an auxiliary arm of a crane in the prior art is installed on one side of a main arm, the gravity center deviates from the center of crane is solved, the problem that operation is difficult when the auxiliary arm is put away and releasedon the side face by manual work is solved, the put-away and releasing efficiency of the auxiliary arm is improved, and the intelligent level and the competiveness of the crane are improved.

Description

technical field [0001] The invention relates to the field of engineering machinery, in particular to a crane. Background technique [0002] Existing tire crane products are all equipped with a jib device. The jib for products below 200 tons is placed sideways on the right side of the main boom, and is transported together with the whole machine, and does not need a special transport cart for special transportation; while products of 200 tons and above, Limited by the width of the vehicle, placing the jib on the side will result in an over-width of the vehicle, which can only be transported on a special transport trolley. When in use, an auxiliary crane is required for auxiliary hoisting to realize the disassembly and assembly of the jib, which is extremely inefficient and expensive. figure 1 It shows a schematic diagram of the top structure of a crane of related technology, such as figure 1 As shown, the jib 2 and the main jib 1 of the crane are arranged side by side above...
