How to Calculate Scissor Lift Length
A scissor jack lift's length is proportional to the scissor support weight together 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; hence, the former determines the latter for a stable scissor jack. An extreme example of this to show the point will be a 20-foot lift length that is featherweight made from Styrofoam that 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.
Determine how high in the air the platform will be lifted to calculate or determine the scissor lift length required to support the weight of both occupants and objects on the platform in relation to the weight of the platform.
In order to reach the necessary height within the weight support parameters, the number of cross sections of scissor folding supports sections which will be required to be extended at their full extension. Lastly, you will never want to ascend a few workers up on a platform along with their materials which is on a platform supported by any kind of structure that is unstable because clearly any type of equipment which is susceptible to tipping would put people in a really dangerous situation.
Each cross section should be weighed to determined the overall length and weight of the scissor lift along with the overall stability of the equipment. When fully extended, determine the angle between the horizontal or ground level against the scissor arms measured.
