Repetitive manual materials handling of heavy loads is common in assembly and is a common cause of low back disorders. The manual manipulation of a heavy load may be made more comfortable by constraining the load to move along a guide. The frictionless guide directs the motion of the load to the goal con guration as the human operator provides forces in directions that are comfortable. In this ...

This paper explores the use of passive guides to assist a human in manipulating heavy loads. A guide acts as a frictionless rail which con nes the load to a one-dimensional curve in its con guration space. In this paper we formulate the problem of designing guides to e ectively assist the human , and we apply the formulation to two types of materials handling tasks: pushing a heavy cart and sin...

In recent years, high speed and automation have been promoted to provide higher efficiency for container handling in cranes handling containers such as container cranes and transfer cranes. To bring about automation in these cases, it is important to detect the positioning of hoisting loads accurately. In 1996, Mitsubishi Heavy Industries, Ltd.(MHI) developed a hoisting load position sensor usi...

Cable suspended robots support a moving platform (MP) in space by several spatially arranged cables with computer-controlled winches. The winches are mounted on base platform (BP). Compared to conventional robots, it is possible to control not only the translational motion of the payload but also its orientation in order to perform, for example, loads handling. By this, cable suspended robots c...

This report is an update of the review for ramp-based baggage handling related literature undertaken in 2005 (Tapley and Riley, 2005). The aim of this review is to present information relating to alternative methods of loading narrow-bodied aircraft that reduce the manual handling related injury and ill-health risks to the handlers, and to identify knowledge gaps. This was used to inform subseq...
