COUNTERWEIGHT FOR AN ELEVATOR, BALLAST WEIGHTS FOR THIS COUNTERWEIGHT AND ELEVATOR EQUIPPED THEREWITH

摘要

The counterweight according to the invention for an elevator with a frame (1) comprising two vertical U- shaped posts (3) parallel and opposed to each other and connected to each other by at least one upper cross-beam (5) and one lower cross-beam (7), wherein the wings of the vertical posts accommodate flat ballast weights forming a mass and piled up on each other in the frame (1), is characterized in that the upper ballast weights (11'a, 11'b), at least those located at a higher height than that of the conventional tilted assembly of the lower one-piece ballast weights (11'), comprise at least two parts interlocked with each other so that they can be successively assembled by interlocking them in a plane and in rows between the two posts (3), said interlocking providing a good lateral stiffness to avoid the lateral escape of said two interlocked ballast weight parts (11'a and 11'b) out of said frame (1) during counterweight displacement. ® KIPO & WIPO 2007
