How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the weight of the scissor support along with the integrity of the steel cross sections more than the length. The scissor structure's weight together with the length is corollaries of each other; therefore, the former determines the latter for a stable scissor jack. An extreme example of this to illustrate the point would be a 20-foot lift length which is featherweight made from Styrofoam that is pretty much weightless. It definitely can not support at much of a height and will not be able to support much at all.
In order 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 along with 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 required to be extended at their full extension. Finally, you will never want to ascend some workers up on a platform along with their supplies that is on a platform supported by any type of structure which is unstable since clearly any kind of machine that is prone to tipping would put people in an extremely dangerous situation.
Each cross section should be weighed to determined the overall length and weight of the scissor lift in addition to the overall stability of the machinery. When fully extended, determine the angle between the horizontal or ground level against the scissor arms measured.
