Method for hoisting ultra-high overweight equipment in closed workshop and special sling

Abstract

The present invention relates to a method for hoisting ultra-high overweight equipment in closed workshop and a special sling. The hoisting method includes steps as follows: constructing an inclined slope near an equipment installing base; turning the equipment for making the installing direction in a right direction; parallel moving the equipment to a place near the inclined slope; placing the equipment on the inclined slope; raising up the equipment slowly and placing on the inclined slope bottom platform; hoisting the equipment in position cooperating with the special sling; the special sling includes a first girder, a second girder, a hanging ear, the first girder connects with the second girder showing included angle, one side of the first girder far from the second girder is equippedwith a first girder hanging ear, two sides of the second girder are equipped with a second girder hanging ear. The method uses two hydrostatic triggers, a bridge type hoisting engine in workshop andthe sling for cooperating lifting the ultra-high overweight equipment which can solve problem of insufficient weight-lifting capability; the inclined slope for storing equipment temporarily near the equipment base which can solve defect of limited workshop beam orbital height by ultra-high.

Description

technical field [0001] The invention relates to the technical field of hoisting heavy equipment in a workshop, in particular to a method for hoisting ultra-high and super-heavy equipment in a closed workshop and a special lifting tool. Background technique [0002] Large-scale lifting equipment is generally used to install overweight equipment in the factory building. However, due to the elevation of the crane beam track of the large-scale lifting equipment and the limitation of the height of the factory building, it is not realistic to use large-scale lifting equipment in the factory building. For example, when installing a large-diameter thick-walled rolling pipeline, the weight of the punching hydraulic machine frame reaches 200t, the height of 15.8m exceeds the elevation of the crane beam track surface by 15m, and the conditions of the site and surrounding environment are limited, and one or two machines cannot be used in the installation area. Large-scale lifting equipm...
