Length and Thickness of L Angles

You might want to beef up you design. If that is the motor, the torqure will destroy your scissor lift.

Need to be more specific and include dimensions of motor to be able to judge. The sisscor lift actually looks like it might be either square stock or square tubing can't be sure without any dimensions or the file.

i think the total weight required to lift is enough to calculate the thickness of the langle.

"Can anyone help me with how to find the length of web in the L angle and its thickness for the structure below? The weight of the motor is 300kg."

We need to know the lengths of the blue and red elements.

Are there 3 hydraulic cylinders or only one?

Does one cylinder raise and lower the assembly?

Do the two cylinders move the motor out to the end or how far?

the length of the blue element is 1500.

length of red element is 500.

there are three cylinders.

one cylinder rises the whole.

two cylinders move out to the end

This appears to be essentially the same device shown in post "Center of Gravity"

What are the units of measurement?

The unit as shown is unstable as it appears the center of gravity of the system is outside the bottom support points. A counterweight is indicated of the same mass as the motor and at a greater distance from that end than the motor mass overhangs the bottom support points.
