This is a Protema crate lifter with roller, a special tool suitable for handling plastic crates used in various industries to hold small parts that can quickly become very heavy or when unpacking goods onto shelves.
A crate turner tool can be used to lift, turn and empty the content of crates. A more ergonomic way to push goods onto and off a platform is by using a roller attached to the front or sides of the platform. To facilitate manual handling even more rollers can also be placed all across the platform surface.
Another good solution is using a telescopic platform that enables longer reach, which is very popular in the computer server maintenance business.
