Apr 20, 2012· Design Equations for Scissor Lift: For a scissor lift that has straight, equal-length arms, i.e. the distance from the horizontal-jack-screw attachment (or horizontal hydraulic-ram attachment) point to the scissors-joint is the same as the distance from that scissor-joint to …

### Scissor Lift Design Calculation [3no7oo86qgld]

The lift mechanism that was eventually built and implemented was a 3-level scissor lift. In order to analyze the forces throughout the lift structure, a set of mathematical equations was derived. From these equations, it was discovered that prudent placement of a lift's actuator can significantly reduce the forces required of the actuator and ...
