Lifting weight with LEGO Technic!

How much weight can be lifted by LEGO alone? How high can we go?

Various mechanisms are tested including linear actuators, pulley systems with block and tackle, gear racks and large LEGO Technic motors. As part of the build, I utilised a few common types of lift system including a scissor jack and rack system.
