COUNTERWEIGHT DEVICE FOR LIFT

摘要

A counterweight device for a lift comprises a counterweight frame, counterweight blocks (2) and pressing plates (1) for the counterweight blocks. The counterweight frame is a rectangular frame composed of two long vertical beams (4), an upper side beam (3) and a lower side beam (5). A cross drawing plate (7) is fixed between the two long vertical beams (4). A short vertical beam (6) is connected between the cross drawing plate (7) and the middle part of the lower side beam (5). Two counterweight guide slots are formed between the short vertical beam (6) and the two long vertical beams (4). The counterweight blocks (2) are superposed in the two guide slots from bottom to top, respectively. Two pressing plates (1) for the counterweight blocks are fixed between the short vertical beam (6) and the two long vertical beams (4) at an upper end of the counterweight blocks (2), and stride over the two guide slots respectively.
