Companies that manually unload trucks or containers put employees at risk injuries for repetitive lifting and fatigue. When this occurs it can cause employees to slow down, resulting in the need for several people to complete the task. Consequently the task becomes more expensive for the company to hire more of people.
Additionally, other employees might be unable or unwilling to fill in for such physically exhausting tasks leaving companies scrambling. Since implementing the Container Unloader, Yusen found they used fewer employees to unload a container in less man hours with higher employee satisfaction.
