How to Calculate Scissor Lift Length
The length of a scissor jack lift is proportional to the support weight of the scissors and the integrity of the steel cross sections over the length. The scissor structures weight and length are corollaries, meaning that the former determines the latter for a stable scissor jack. An extreme instance of this to show the point will 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 could not 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 platform's weight.
The number of cross-sections of scissor folding supports sections which will be required to be extended at their full extension in order to reach the needed height within the weight support parameters. Finally, you would never want to ascend a few employees up on a platform along with their supplies which is on a platform supported by any kind of unstable structure because obviously any machine which is susceptible to tipping will put individuals in a very dangerous situation.
Determine the weight of each scissor cross-section. This is very important to determining the weight and length of the scissor lift you would require in addition to the overall stability of the machinery. When completely extended, determine the angle between the horizontal or ground level against the scissor arms measured.
