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 along with the length is corollaries of each other; hence, the former determines the latter for a stable scissor jack. An extreme example of this to show the point would be a 20-foot lift length which is featherweight made from Styrofoam which is pretty much weightless. It definitely will not be able to support at much of a height and could not support much at all.
In order to calculate the length of a scissor lift, determine how high in the air you require to support a platform which will support of the weight of the objects and occupants on the platform in addition to the platform's weight.
In order to reach the required height within the weight support parameters, the number of cross sections of scissor folding supports sections that would be necessary to be extended at their full extension. Finally, you would never want to ascend a few workers up on a platform with their materials that is on a platform supported by any type of unstable structure since obviously any machinery which is susceptible to tipping will put people in a very dangerous situation.
Determine the weight of every scissor cross-section. This is very important to determining the weight and length of the scissor lift you will need along with the overall stability of the machine. When completely extended, determine the angle between the horizontal or ground level against the scissor arms measured.
