How to Calculate Scissor Lift Length
A scissor jack lift's length is proportional to the scissor support weight 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 will be a 20-foot lift length which is featherweight made from Styrofoam which is practically weightless. It definitely could not support at much of a height and will not be able to support a lot 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 would support of the weight of the occupants and objects on the platform in addition to the weight of the platform.
The number of cross-sections of scissor folding supports sections that will be required to be extended at their full extension to be able to reach the needed height within the weight support parameters. Lastly, you would never want to ascend some employees up on a platform together with their supplies which is on a platform supported by any type of unstable structure since clearly any machine that is susceptible to tipping will put people in an extremely dangerous situation.
Each cross section must be weighed to determined the overall weight and length of the scissor lift as well as the overall stability of the machine. When fully extended, determine the angle between the ground or horizontal level against the scissor arms measured.
