Abstract
Abstract The present invention relates to hoisting equipment, and more specifically to a method of mounting a long-size heavy object into vertical or close to vertical, position by turning this object about a fixed axle, and to a device for realizing this method. The invention can most successfully be used for mounting into vertical position, or close to it, column- and tower-type apparatuses, transmission line and cableway supports, metal smoke and air chimneys, masts of communication means, pile drivers, and other vertical-type constructions with a weight of 1,000-1,500 tons and more, with lateral dimensions of up to 10 m. and more, and a length of up to 150-200 m. and more. The method according to the invention provides for moving the bottom ends of frame supports in a definite succession towards the supposed axis of turn of the object to be erected, whereto the frame supports are attached by their span pieces. The method cuts the time of erection, and permits using winches of relatively small load capacity.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
133 words
A method to mount a long-size heavy object into vertical or close to vertical, position by turning this object about a fixed axle with the aid of at least two movable frame supports, which before the start of lifting are located at different distances from the axis of turn, are inclined to the longitudinal axis of the object in the direction of its turn, and are by their top ends hinged to the object, consisting in moving towards said axis of turn of said object first the bottom ends of a frame support most distant from said axis of turn, until this support takes vertical position, or a position close to it, and then moving in the same direction the bottom ends of the frame support located nearer to said axis of turn.
Claim 2
Independent Claim
133 words
A method to mount a long-size heavy object into vertical or close to vertical, position by turning this object about a fixed axle with the aid of at least two movable frame supports, which before the start of lifting are located at different distances from the axis of turn, are inclined to the longitudinal axis of the object in the direction of its turn, and are by their top ends hinged to the object, consisting in moving towards said axis of turn of said object first the bottom ends of a frame support most distant from said axis of turn, until this support takes vertical position, or a position close to it, and then moving in the same direction the bottom ends of the frame support located nearer to said axis of turn.
Claim 3
Independent Claim
140 words
A device to realize the method of mounting a long-size heavy object into vertical or close to vertical, position by turning this object about a fixed axle, comprising: at least two frame supports disposed along said object to be erected, the top ends of said supports being hinged to this object; a means to move the bottom ends of these supports; a carriage attached to said means to move it along said object in the direction of said supposed axis of turn of this object, resting on which carriage in the beginning of the erection of said object are the bottom ends of the frame support most distant from said axis of turn of said object, each subsequent frame support starting to rest on said carriage through its bottom ends by the moment the previous frame support takes vertical position.
Claim 4
Independent Claim
140 words
A device to realize the method of mounting a long-size heavy object into vertical or close to vertical, position by turning this object about a fixed axle, comprising: at least two frame supports disposed along said object to be erected, the top ends of said supports being hinged to this object; a means to move the bottom ends of these supports; a carriage attached to said means to move it along said object in the direction of said supposed axis of turn of this object, resting on which carriage in the beginning of the erection of said object are the bottom ends of the frame support most distant from said axis of turn of said object, each subsequent frame support starting to rest on said carriage through its bottom ends by the moment the previous frame support takes vertical position.
Claim 5
Dependent Claim
62 words
A device as claimed in claim 2, wherein said frame support most distant from said supposed axis of turn of said object to be erected, consists of a frame and jibs, which are shorter than the frame, and are hinged to this frame from the side of said axis of turn, said carriage first taking up the bottom ends of said jibs.
Claim 6
Dependent Claim
26 words
A device as claimed in claim 2, wherein said bottom ends of said frame supports have heels, and said carriage has seats congruent with these heels.
Claim 7
Dependent Claim
28 words
A device as claimed in claim 2, wherein the top ends of said frame supports in the beginning of erection of said object are located over this object.
Claim 8
Dependent Claim
30 words
A device as claimed in claim 2, wherein said frame support most distant from said supposed axis of turn of said object, is connected to the end of this object.
