FIELD: transport engineering; load-lifting machinery. ^ SUBSTANCE: invention relates to load-lifting equipment used in different spheres of application, mainly, for servicing and repair of automobiles, particularly, to lifts with hand drives. Proposed lift has base in form of frame with fitted-on running wheels 1 and support wheels 2 consisting of left-hand part 3 and right-hand part 4. Lower end of left-hand part 3 is furnished with pedal 5 with stop "E", and upper end is hinge-coupled with lower end of intermediate lever 6 on upper end of which toothed sector 7 is rigidly secured which is installed for constant meshing with other toothed sector 8 rigidly secured on upper end of lifting lever 9. The latter is hinge-connected with main lever 10, and connected by lower end with lifting wheel 11 and cross support beam 12 and is installed parallel to upper lifting lever 13. The latter is hinge-coupled by upper end with right-hand part 4 of base and by lower end, is hinge-connected with cross support beam 12 forming, together with right-hand part 4 of base a parallelogram mechanism. Shackle 14 is hinge-coupled with intermediate lever 6 and main lever 10. Lifting wheels 11, cross supports beam 12 and lower lifting lever 9 are installed on one axle "C". Stop 15 is mounted on left-hand part 3 of base. Adjustable support 16 is installed on cross support beam 12. Upper end of left-hand part 3 of base, lower end of intermediate lever 6 and support wheels 2 are installed on common axle "B". ^ EFFECT: reduced overall dimensions and weight of lift. ^ 3 cl, 4 dwg
