Manual material handling tasks are typically complex, and cart handling is no exception; the operator lifts the materials to the cart, starts the cart moving, sustains the motion of the cart, turns the cart, brakes the cart and lifts the objects from the cart. Determining the acceptability of cart-handling forces, however, has traditionally been limited to analyses of starting the cart moving, sustaining the movement and turning the cart. Dr. Albin will discuss techniques for evaluating the acceptability of push-pull forces by taking into consideration the compound interaction of all the different exertions performed.
