These units are the modern way to manually load and unload pallets by bringing the level and location of the top of load closer to the person doing the work. They are excellent additions to any loading or unloading process using pallets as the transportation medium. They reduce worker fatigue, improve safety and eliminate situations that can lead to back injuries or damage to sensitive products. Typical applications are in manufacturing, processing and distribution. These are true ergonomic tools. They are spring-free and designed and manufactured to automatically raise and lower pallets during loading or unloading and to turn pallets so the worker does not have to reach, stoop or strain, and the rotating ring minimizes walking or stretching during the loading or unloading process. As the load changes, the unit automatically either raises or lowers, keeping the top of the load at the optimum height.
