Lifting plastic crates is easy with the right tool. At TAWI we manufacture special crate tools for vacuum lifters which are suitable for all types of containers and plastic crates.
The tools are designed to suit the dimensions of each crate. Shifting the crate from one place to another is often carried out with a forked tool. If you need the turning/tilting function added, a couple of suction cups will help keep a steady grip on the container while the contents are being emptied.
