How to Calculate Scissor Lift Length
A scissor jack lift's length is proportional to the weight of the scissor support 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 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 would not be able to support at much of a height and will not be able to support much at all.
Determine how high in the air the platform would 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 platform's weight.
To be able to reach the necessary height within the weight support parameters, the number of cross sections of scissor folding supports sections that will be necessary to be extended at their full extension. Finally, you will never want to ascend some employees up on a platform along with their supplies that is on a platform supported by any type of unstable structure as clearly any equipment which is prone to tipping would put people in an extremely dangerous situation.
Every cross section must be weighed to determined the overall length and weight of the scissor lift as well as the overall stability of the machine. When entirely extended, determine the angle between the scissor arms measured against the horizontal or ground level.
