How to Calculate Scissor Lift Length
A scissor jack lift's length is proportional to the weight of the scissor support together with the integrity of the steel cross sections more than the length. The weight of the scissor structure combined with the length is corollaries of each other; therefore, the former determines the latter for scissor jack stability. An extreme example of this to illustrate the point would be a 20-foot lift length which is featherweight made from Styrofoam that is practically weightless. It certainly could not support at much of a height and would not be able to support much at all.
Determine how high in the air the platform will be raised to determine or calculate the length of the scissor lift needed to support the weight of both occupants and objects on the platform in relation to the platform's weight.
The number of cross-sections of scissor folding supports sections which would be required to be extended at their full extension in order to reach the required height within the weight support parameters. Finally, you would never want to ascend some employees up on a platform with their materials that is on a platform supported by any type of unstable structure since clearly any kind of machinery that is susceptible to tipping would really put individuals in an extremely dangerous situation.
Determine the weight of every scissor cross-section. This is very important to determining the length and weight of the scissor lift you would need as well as the overall stability of the machinery. When entirely extended, determine the angle between the scissor arms measured against the ground or horizontal level.
