Abstract

Truck drivers suffer work injuries to a higher extent than most other occupations. The HTO concept and the interaction framework were applied in a pre-study leading to a redesign of a new powered pallet truck. The old truck was evaluated using a literature study, interviews, observations, injury statistics and benchmarking, as part of the HTO analysis. The analyses showed that the driver often stood on the rear part of the platform with the heels outside the platform, making them vulnerable to injury. The injury statistics also showed that drivers of powered pallet trucks had more heel injuries than drivers of other truck types. There were two reasons for this. The steering arm was slightly too long, and the vibration damping was better the further back the drivers stood on the platform. This study led to redesign of the steering arm and platform suspension in the new truck generation. The combination of the HTO concept and the interaction framework supported the analysis in identifying relationships that otherwise would not have been obvious.
