||Collecting shopping trolleys: A manual handling injury concern
||Oct.2004, Vol.20, No.5, p.433-440. Illus. 16 ref.
||Shopping trolley collection was observed at six shopping centres. These observations showed that some collectors use possibly unsafe practices in nesting and moving columns of trolleys. To assess whether these practices could lead to manual handling injuries, a series of experiments were conducted. The forces encountered in two observed methods of nesting trolleys were measured and compared. The initial and sustained push forces required to move columns of up to 10 shopping trolleys were measured on the flat asphalt surface of a shopping centre car park. The push forces required to move larger numbers of nested trolleys were estimated using regression analysis. Pushing more than 13 nested trolleys was found to exceed recommended push forces and, hence, could lead to manual handling injury.
