How to Calculate Scissor Lift Length
A scissor jack lift's length is proportional to the weight of the scissor support along 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; thus, the former determines the latter for a stable scissor jack. An extreme instance of this to illustrate the point would be a 20-foot lift length which is featherweight made from Styrofoam which is pretty much weightless. It certainly would not be able to support at much of a height and could not support a lot at all.
To be able to calculate scissor lift length, determine how high in the air you require to support a platform that will support of the weight of the objects and occupants on the platform in addition to the platform's weight.
To be able to reach the required height within the weight support parameters, the number of cross sections of scissor folding supports sections which would be required to be extended at their full extension. Finally, you would never want to ascend a few workers up on a platform with their supplies which is on a platform supported by any kind of structure which is unstable as clearly any kind of machinery that is prone to tipping will really put people in an extremely 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 require along with the overall stability of the machinery. When entirely extended, determine the angle between the ground or horizontal level against the scissor arms measured.
