“…In other branches of industry as well, e.g. in transport, the food industry, the retail trade or the nursing service, wheeled containers, trolleys or two-wheeled carts are employed to reduce the proportion of lifting and carrying activities (Jung et al, 2005). These transport aids are mostly pushed or pulled together with their loads.…”

“…Their study showed that wheels with a 25 cm diameter were 16% faster than those with a 7.5 cm diameter. Carts with four wheels are preferable because they eliminate the friction force between the wheels and the floor [12]. It has also been recommended that the force that users need to exert to change the direction of travel can be reduced by using swivel wheels.…”

Expert recommendations regarding trolley specifications and customer expectations of trolley features are equally important in the development of a customer-oriented shopping trolley that minimizes the risk of musculoskeletal injuries. However, little is known about such customer expectations, and hence this study aimed to examine the views of Hong Kong adults on shopping trolleys.A cross-sectional survey was conducted with a sample of 140 Chinese adults aged 40 or over with no cognitive or communication impairments. These adults were approached in markets, supermarkets, and public parks in Hong Kong. Individual face-to-face interviews using a questionnaire were used to collect the data.Fifty-six (40%) of the participants were current users, 32 (23%) were ex-users, and 52 (37%) were non-users of shopping trolleys. More of the user and ex-user participants perceived shopping trolleys to be energy saving and protective of the joints. Lightness and easy storage, a pulling and pushing motion, suitability for use on stairs, and adjustable handle height were the trolley features most frequently expected by the participants. The user and ex-user participants rated lightness, a pushing motion and changeable trolley bags to be comparatively more important than the non-user participants.The findings have implications for the development of an evidence-based shopping trolley design. Close cooperation is needed between ergonomists and design and engineer experts to develop an ergonomically designed shopping trolley that prioritizes the health and safety of its users.

“…The push force is affected by a number of factors. For example the forces required when manoeuvring carts is less when pushing forwards than when pulling backwards (Lawson et al, 1993;De Looze et al, 2000;Jung et al, 2005). Push handle height, weight load and orientation can also affect push forces.…”

“…Push handle height, weight load and orientation can also affect push forces. A review of the evidence by Jung et al (2005) showed weight load is the parameter which has the most effect in pushing wheeled device. Although handle height is also of great importance.…”

Ensuring equal opportunity to all transport modes, including air travel, allows disabled people the same freedom of travel available to the rest of the population. However, boarding of wheelchair users onto airplanes is physically demanding for attendant airline or airport personal whom assist and time consuming and costly for airlines. This paper presents a comparison between two methods of boarding wheelchair users, measuring the forces required and the duration taken. Participants were asked to act as attendants and to board weighted wheelchairs onto simulated aircraft vestibules using two different manoeuvre methods ("going forwards" and "going backwards"), with two different loadings ("light" and "heavy") in two different access scenarios ("level access" and "sloped access") between the jet-way/scissorlift and the aircraft. The results reveal that the "going backwards" technique is a slightly faster manoeuvre method but no difference in the forces required exist between the two methods. The weight of the wheelchair affected the forces required to complete the boarding and exceeded health and safety guidelines for attendants. Reducing the height of the step between the aircraft and the jet-way or scissor-lift is recommended. Relevance to Industry: The research highlights the juxtaposition between the need to board wheelchair users and the excessive force required by the attendants propelling the wheelchair.
