Hand pulley by Easy Scale Scaffolding Ltd.
Securpulley is a patented hand pulley with an automatic brake. Designed to lift up to 110 pounds with a 4:1 safety ratio, this tool will suspend a load whenever the operator stops lifting. If the handler needs to rest, wipe hands or leave the job site temporarily, the pulley will safely hold the load in place. Even if one drops the rope or trips and falls, the load will not fall-the automatic brake will instantly lock, avoiding an accident.
