Abstract

This thesis is focused on problems of scissor lifts and solutions. For the chosen solution is created kinematic scheme and power analysis of scissor lifts. Scissor lifts are for lifting up burdens to desired position. The goal of the thesis is the proposal of electro-hydraulic drive system for scissor lifts including a design of main aspects and constructing documentation to hydraulic unit. In the following part of the thesis is described an analysis of natural frequency hydraulic drive and a determination of a speed profile of the scissor lifts. In the conclusion a comparison is given between the suggested propulsion and the chosen alternatives.
