How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the support weight of the scissors and the integrity of the steel cross sections over the length. The scissor structures length and weight are corollaries, meaning that the former determines the latter for a stable scissor jack. An extreme instance of this to illustrate the point will be a 20-foot lift length which is featherweight made from Styrofoam that is pretty much weightless. It certainly would not be able to support at much of a height and can not support much at all.
To be able to calculate the length of a scissor lift, 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 as well as the weight of the platform.
The number of cross-sections of scissor folding supports sections that would be required 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 which is on a platform supported by any type of structure which is not stable because obviously any equipment that is susceptible to tipping would put individuals in a very dangerous situation.
Each and every cross section must be weighed to determined the overall weight and length of the scissor lift as well as the overall stability of the machinery. When entirely extended, determine the angle between the ground or horizontal level against the scissor arms measured.
