Well the key components are in this [Worm Gear Pack](http://www.bricklink.com/catalogItem.asp?S=9854-1). I'm sure the individual pieces can be had cheaper than the one set of these for sale on BrickLink.

# What is the best system for lifting things without pistons?

(Asked by: username_0 on 2015-02-15)

I am building a big walker thing. It has a mining laser at the bottom that can be lifted on one half, and the other is attached to the vehicle.

However, I can't seem to find a way, because the hooks attached to the strings come off to easily. The studs are also facing down and I am not using Mindstorms.

I'm looking for a purely LEGO solution.

Application of said parts are left as an exercise for the reader, though since OP says they're not using Technic, this might be a moot answer.
