How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the scissor support weight 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 illustrate the point will be a 20-foot lift length that is featherweight made from Styrofoam which is pretty much weightless. It definitely can not support at much of a height and would not be able to support much at all.
Determine how high in the air the platform would be raised 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.
To be able to reach the required height within the weight support parameters, the number of cross sections of scissor folding supports sections which will be necessary to be extended at their full extension. Lastly, you would never want to ascend a few workers up on a platform with their supplies which is on a platform supported by any type of structure which is unstable as obviously any type of equipment that is susceptible to tipping would really put individuals in an extremely 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 entirely extended, determine the angle between the scissor arms measured against the horizontal or ground level.
