Abstract

The invention provides a hydraulic double-type crane which comprises a gantry unit, a skidding unit and dismounting and mounting units, wherein the gantry unit comprises gantry top sections, at least one gantry standard section connected to the lower parts of the gantry top sections as well as gantry bases connected below the gantry standard section; the dismounting and mounting units are connected to the gantry bases and comprise gantry self-dismounting and mounting systems and jacking sleeve frames; and the skidding unit is connected above the gantry top sections and comprises a skidding beam, a skidding bearing beam and a skidding beam skidding mechanism which can drive the skidding beam to skid on the skidding bearing beam. According to the hydraulic double-type crane, no-load and loaded skidding of the skidding beam can be achieved, and the skidding beam span can be adjusted.

Description

technical field [0001] The invention relates to a large-scale hoisting machine, in particular to a crane and an installation method for extra-large equipment (such as a chemical reactor). Background technique [0002] Most of the hoisting and hoisting machinery for extra-large equipment (such as chemical reactors) now consists of large crawler hoisting equipment and small hydraulic single-gantry cranes. The following disadvantages exist in the hoisting of large-scale equipment: 1. When installing large-scale equipment, the use of large-scale crawler hoisting equipment has disadvantages such as long installation period, large floor area, and high risk factor. 2. The crawler hoisting equipment requires a large area for site hardening, and the economic benefits of large-scale hoisting projects are poor. 3. The use of a hydraulic single gantry crane needs to be equipped with a wind rope, and at the same time it needs to harden the foundation, resulting in high cost. Contents ...
