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 along 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 would be a 20-foot lift length that is featherweight made from Styrofoam that is pretty much weightless. It definitely could not support at much of a height and can not support a lot at all.
In order to calculate scissor lift length, determine how high in the air you have to support a platform that would support of the weight of the occupants and objects on the platform along with the platform's weight.
The number of cross-sections of scissor folding supports sections which would 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 workers up on a platform along with their materials that is on a platform supported by any kind of structure that is not stable since obviously any type of machine that is prone to tipping would put individuals in a very dangerous situation.
Every cross section must be weighed to determined the overall weight and length of the scissor lift as well as the overall stability of the machinery. When fully extended, determine the angle between the scissor arms measured against the ground or horizontal level.
