Mechanical Scissor Lift

摘要

A scissor lift incorporating a trolley; lateral and oppositely lateral rollers; axles positioning the rollers at lateral and oppositely lateral sides of the trolley; torque cancelling “C” brackets mounted upon the trolley's lateral and oppositely lateral sides; a jack screw actuator connected operatively to the trolley for alternatively longitudinally and oppositely longitudinally moving the trolley; lateral and oppositely lateral roller tracks having longitudinal edges, each of the tracks supporting one of the rollers and each of the “C” brackets engaging one of the longitudinal edges; a scissor arm matrix having a lower longitudinal end connected to the trolley; a platform attached to the scissor arms' upper end; and a motor connected operatively to a chassis for longitudinally moving the jack screw actuator and for vertically moving the platform.

主权项

1. A scissor lift comprising:
(a) a trolley having a lateral and oppositely lateral sides; (b) lateral and oppositely lateral rollers; (c) mounting means respectively positioning the lateral and oppositely lateral rollers at the trolley's lateral and oppositely lateral sides; (d) lateral and oppositely lateral “C” brackets respectively opening at the trolley's lateral and oppositely lateral sides; (e) a jack screw assembly comprising a helically threaded shaft, said assembly being connected operatively to the trolley for alternatively longitudinally and oppositely longitudinally moving the trolley; (f) lateral and oppositely lateral tracks having longitudinally extending edges and respectively supporting the lateral and oppositely lateral rollers, each of the “C” brackets' openings receiving one of the longitudinally extending edges; (g) a scissor arm matrix having a lower end connected operatively to the trolley; (h) a load platform connected operatively to an upper end of the scissor arm matrix; and (i) turning means connected operatively to the jack screw assembly for actuating the trolley's alternative longitudinal and oppositely longitudinal movements and for alternatively lowering and raising the scissor arm matrix and load platform.
