Problems solved by technology

Due to the limited hoisting capacity of the crane, and the larger the hoisting width, the lower the hoisting weight; when the hoisting distance is long and the weight of the hoisted items is heavy, it is often necessary to replace the crane with a larger hoisting capacity, which means that it is necessary to Greater equipment investment will have a greater impact on the economics of project construction

Abstract

The invention discloses a lifting tool specially used in water. The lifting tool comprises at least two buoyancy tanks which are symmetrically and fixedly arranged on a connecting rod of a pair of clamping portions of a connecting clamp. According to the lifting tool specially used in water, compared with a traditional overwater lifting manner, buoyancy is fully used for assisting in floatation, it is avoided that lifting equipment with larger capacity is replaced, the requirement for the lifting equipment is lowered, the cost is reduced, and lifting efficiency is improved.

Description

technical field [0001] The invention relates to the field of water engineering construction. More specifically, the present invention relates to a special sling in water. Background technique [0002] During the construction of water projects, some areas need to be completed by land cranes. Due to the limited hoisting capacity of the crane, and the larger the hoisting width, the lower the hoisting weight; in the case of long hoisting distance and heavy weight of hoisted objects, it is often necessary to replace the crane with a larger hoisting capacity, which means that it is necessary to Greater equipment investment will have a greater impact on the economics of project construction. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems and to provide at least the advantages which will be described later. [0004] Another object of the present invention is to provide a special lifting device in water....
