Interesting, BUT this type of project scares the hell out of me. Raising heavy weights overhead using un-engineered machinery is courting disaster. Any number of structural failures risk catastrophic failure, dropping the load on the operator or an innocent bystander. Unless you have a mechanical engineering background or access to someone who does this is probably a project best avoided. Case in point; the forks are the most highly stressed component of a forklift and the builder chose to use welded steel tubing in lieu of forged high strength steel commonly used in such an application.
