Abstract

The invention provides an elevator with a balancing counterweight capable of easily and safely supplying the quake-proof reinforcement from a box in an elevating road of the elevator. The elevator hasthe balancing counterweight (1) connected with the box by a rope, the balancing counterweight (1) can be guided by a guide rail (9) to elevate relatively to the box, the balancing counterweight (1) has a pair of columns (2) with openings which are oppositely arranged side by side and the I-shaped cross section, an upper frame (3) and a lower frame (4) connected with the top and bottom ends of twocolumns (2), a plurality of counterweight sheets (6) inserted into the openings in the laminating state and protruded toward the fore-and-aft direction of two columns, and a connecting body (7) mounted on the front faces of two columns at the center position of the counterweight sheets (6) in the vertical direction, wherein a pair of L-shaped installation sheets (7b) are respectively arranged atboth side ends of the connecting body in the long side direction and are respectively fixed at the front faces of two columns by a bolt (8).

Description

technical field [0001] The present invention relates to an elevator having a counterweight that is raised and lowered relative to the car, and more particularly to an elevator with anti-seismic reinforcement applied to the counterweight. Background technique [0002] Generally, in an elevator, a car and a counterweight are provided in the hoistway, and the two ends of the main rope wound on the pulleys of the winding machine arranged above the hoistway hang down the car and the counterweight respectively. The rotation of the pulley causes the counterweight to be guided by the guide rails provided in the hoistway, whereby the car and the counterweight move up and down relative to each other. The balance counterweight is composed of the following parts: a pair of columns having a U-shaped cross-section, the front side, the side surface, and the rear side, which are arranged side by side with mutual openings facing each other; the upper frame and the lower frame connecting the ...
