CHECK WEIGHT Russian patent published in 2006 - IPC B66C13/18 

FIELD: mechanical engineering; testing facilities.

SUBSTANCE: invention relates to testing of load-lifting and transport machines. Proposed check weight made in form of pack contains blocks 2 of preset mass with through recess in height and round section grips for coupling with slings. Each block has centering member in form of truncated pyramid with lower base arranged symmetrically relative to axes of symmetry of block on its upper plane. Recess 7 corresponding to centering member is made also in form of truncated pyramid from side of lower plane 6 of each block to fix blocks relative to each other and form wedge clearance between lower and upper planes of adjacent blocks non-occupied, respectively, by recess and centering member mentioned above. Wedge clearance between blocks increased in direction from line of contour of lower base of centering member square to line of outer contour of assembly pack. Centering member and assembly pack block are made integral from one material.

EFFECT: simplified design, reduced metal usage, improved reliability of check weight.
