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 scissor structure's weight combined 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 show the point would be a 20-foot lift length that is featherweight made from Styrofoam which is pretty much weightless. It certainly will not be able to support at much of a height and will not be able to support a lot at all.
In order to calculate scissor lift length, determine how high in the air you need to support a platform which will support of the weight of the occupants and objects on the platform in addition to the platform's weight.
The number of cross-sections of scissor folding supports sections that will be necessary to be extended at their full extension to be able to reach the required height within the weight support parameters. Finally, you would never want to ascend a few workers up on a platform with their materials that is on a platform supported by any type of unstable structure since obviously any type of equipment which is susceptible to tipping will 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 as well as the overall stability of the machine. When completely extended, determine the angle between the horizontal or ground level against the scissor arms measured.
