Ener the weight of the payload, weight of the arms, and the angle between the arms and the ground to to determine the scissor lift force.

Scissor Lift Force Formula

The following equation is used to calculate the Scissor Lift Force.

F = (W+(WA/2)) / (Tan(a))
• Where F is the force (lbf)
• W is the weight of the payload (lbf)
• WA is the weight of the scissor arms (lbf)
• a is the angle between the arms and the ground (degrees)

To calculate a scissor lift force, add half the weight of the scissor arms to the weight of the payload, then divide by the tangent of the angle between the arm and the ground.

What is a Scissor Lift Force?

Definition:

A scissor lift forces pallets from place to place without any physical contact. The device itself completely handles the movement of the pallet, and it’s done through air pressure.

How to Calculate Scissor Lift Force?

Example Problem:

The following example outlines the steps and information needed to calculate Scissor Lift Force.

First, determine the weight of the payload. In this example, the weight of the payload is 50 lbf.

Next, determine the weight of the scissor arms. These are measured to be 50 lbf.

Next, determine the angle between the arms and the ground. This is measured to be 20 degrees.

Finally, calculate the scissor lift force using the formula above:

F = (W+(WA/2)) / (Tan(a))

F = (50+(50/2)) / (Tan(20deg))

F = 206.06 lbf
