Abstract

The invention relates to the technical field of lifting equipment, in particular to a super-lifting device and lifting equipment. The super lifting device provided by the present invention includes two super lifting jibs, the first ends of the two super lifting jibs are used to connect with the lifting main boom of the lifting equipment, and each super lifting jib surrounds the respective corresponding The pivot axis is pivotally arranged with respect to the main boom, wherein, on the side where the corresponding super-lift jib frame is located, the side of the pivot axis away from the left and right middle planes of the main boom is relatively close to the lifting main boom. One side of the left and right split planes of the heavy main boom is inclined downward. In this way, during the rotation of the two super-lifting jibs around the pivot axis relative to the main boom, the two super-lifting jibs can be deployed or moved closer, making the deployment control of the super-lifting device more convenient, fast and accurate , which can effectively improve the stability of deployment positioning.

Description

technical field [0001] The invention relates to the technical field of lifting equipment, in particular to a super-lifting device and lifting equipment. Background technique [0002] Due to the continuous large-scale construction and development of large-scale engineering projects such as petroleum, wind power, and steel at home and abroad, and the equipment specifications and weights of these projects are also increasing, this will affect the lifting weight of cranes and other lifting equipment. Performances such as lifting range and lifting height have put forward higher and higher requirements. In order to meet the performance requirements of modern machinery for lifting equipment and give full play to the boom performance of super-large-tonnage lifting equipment, super-lifting devices are usually added on the basis of the original boom. [0003] The super-lifting device is a device set up to improve the lifting capacity of the lifting equipment in the slewing plane and ...
