How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the support weight of the scissors as well as 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 scissor jack stability. An extreme instance 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 certainly will not be able to support at much of a height and could not support much at all.
To be able to calculate the length of a scissor lift, determine how high in the air you need 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.
To be able to reach the required height within the weight support parameters, the number of cross sections of scissor folding supports sections that would be required to be extended at their full extension. Lastly, you will never want to ascend some workers up on a platform along with their supplies that is on a platform supported by any kind of unstable structure because obviously any kind of equipment that is prone to tipping will really put individuals in an extremely dangerous situation.
Each cross section should be weighed to determined the overall weight and length of the scissor lift in addition to the overall stability of the equipment. When completely extended, determine the angle between the horizontal or ground level against the scissor arms measured.
