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 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 example of this to show the point would be a 20-foot lift length which is featherweight made from Styrofoam that 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 will 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.
The number of cross-sections of scissor folding supports sections which will be required to be extended at their full extension to be able to reach the needed height within the weight support parameters. Finally, you will never want to ascend some employees up on a platform along with their supplies which is on a platform supported by any kind of structure which is unstable as obviously any type of equipment which is susceptible to tipping would put individuals in a very dangerous situation.
Each cross section should be weighed to determined the overall weight and length of the scissor lift in addition to the overall stability of the equipment. When entirely extended, determine the angle between the scissor arms measured against the horizontal or ground level.
