How to Calculate Scissor Lift Length
The scissor jack lift's length is proportional to the scissor support weight as well as the integrity of the steel cross sections over the length. The scissor structures weight and length are corollaries, meaning that the former determines the latter for a stable scissor jack. An extreme example of this to illustrate the point would be a 20-foot lift length that is featherweight made from Styrofoam which is pretty much weightless. It certainly could not support at much of a height and can not support a lot at all.
In order to calculate the length of a scissor lift, determine how high in the air you need to support a platform that would support of the weight of the objects and occupants on the platform as well as the weight of the platform.
The number of cross-sections of scissor folding supports sections which would be necessary to be extended at their full extension to be able to reach the needed height within the weight support parameters. 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 kind of unstable structure as clearly any equipment that is susceptible to tipping would really put individuals in a really 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 would need as well as the overall stability of the equipment. When completely extended, determine the angle between the scissor arms measured against the ground or horizontal level.
