Aspects to improve cabin comfort of wheel loaders andexcavators according to operatorsAbstractComfort plays an increasingly important role in interior design of earth moving equipment. Although research has been conducted on vehicle interiors of wheel loa- ders and excavators, hardly any information is known about the operator’s opinion. In this study a questionnaire was completed by machine operators to get their opinion about aspects which need to be improved in order to design a more comfortable vehi- cle interior. The results show that almost half of the operators rate the comfort of th- eir cabin‘‘average’’ or ‘‘poor’’. According to the operators, cab comfort of wheel loaders can be increased by improving seat comfort. Besides improving seat comfort, cabin comfort of excavators can be improved by changing the cab design (including dimensions, ingress/egress), view, reliability, and climate control.Keywords: Cabin comfort; Operators’ opinion; Earth moving equipmen t.1. IntroductionComfort plays an increasingly important role in vehicle design. As machine operators of earth moving equipment often spend long hours in their vehicle— some- times even more than 8 h a day—comfort is a major issue in interior design of these machines.Operating earth-moving machinery is not a physically heavy job and can be sustained for long periods.Nevertheless, operating such a machine appears to be a risk factor for musculoskeletal disorders, especially when the task is not interrupted by other working activities or breaks. Zimmerman et al. (1997) showed that the main problems of earth-moving machinery operators concern physical complaints in the neck/ shoulder and low back region, general fatigue and feelings of discomfort. This might be attributed to a combination of static load during prolonged sitting— frequ- ently in awkward postures—exposure to whole body vibrations, and handling and steering the machine(Zimmerman et al., 1997; Tola et al., 1988; de Looze et al.,2000).A comfortable well-designed vehicle interior may reduce awkward postures and provide an environment that stimulates optimal operator performance. Based on a literature review about musculoskeletal disorders and their risk factors, Zimmerman et al. (1997) made four recommendations for reducing work-related musculoskeletal disorders among operators: minimizing of magnitude and frequency of vibration rea- ching the operator; locating controls optimally to minimize reach distances, trunkflexion and trunk rotation; providing maximum operator visibility from an upright supported seated posture; and taking regular breaks to minimize the effects of sus- tained postures. Improvements of cab comfort are very often based on reducing the risk factors for work-related musculoskeletal disorders (Zimmerman et al., 1997; Attebrant et al., 1997). Only a few studies have mentioned aspects which operators wishto see improved. Nakada (1997) describes the desirability ranking for dump trucks and wheel loaders given by product creators, designers, design engineers, operators and young people. Nakada, (1997) shows that much design attention has been paid to instrument panel/monitors and meters and the operator seat. Unfor- tunately, the operators’ opinions cannot be distinguished in Nakada’s study (1997).However, in order to design a comfortable vehicle interior, the opinion of the operators is important as they are the end-users of the machines. Their user expe- rience may be of great help designing a more comfortable vehicle interior. The aim of the current study is to find aspects mentioned by wheel loader and excavator ope- rators, which can be used to improve the comfort of vehicle interiors in the future. In this article we describe the results of a questionnaire given to 273 machine operators. They were asked their opinion about their current machine, their future demands and aspects they considered important to work well with the machine. This allowed us to identify aspects that need improvement in machine design.2. Method2.1. SubjectsA convenience sample was obtained through approaching operators visiting Ba-uma (the world’s largest exhibition for construction equipment). Most of the parti- cipants were wheel loader operators (n = 61) and excavator operators (n=212). The others (n = 65) were operators of several construction machines (e.g., mobile cranes, dozers, tower cranes, off-road trucks). Only the results for wheel loader and excava- tor operators are presented in this article, as they account for 18% and 62.7% of the total number of respondents respectively. Figs. 1 and 2 show a typical wheel loader and excavator.2.2. QuestionnaireData were collected by means of a questionnaire which was completed during an interview. The questionnaire was divided into three parts: (1) characteristics of the population, (2) evaluation of the current machine being operated, and (3) future de- mands on earthmoving machinery. In the first part we asked the operator’s age, y ears of experience as operator, the kind of machinery being operated and its age. In the se- cond part of the questionnaire, operators evaluated their machine by rating overall comfort and their opinion of specific parts of the machine on a four-point scale (very good, good, average, poor). Finally, two open questions asked about the operator’s f- uture demands: what improvements would make the machine more comfortable and what aspects are the most important to work well with the machine.2.3. Data analysisData were sorted by machine type, after which the responses of wheel loader operators and excavator operators were separately analyzed. Within these groups, operators of older machinery (≥4 years old) were separated from operators of newer machinery (〈4 ye ars old). In addition, the categories ‘‘very good’’ and‘‘good’’ were combined (‘‘very good/good’’) and the categories ‘‘average’’ and ‘‘poor’’ were com- bined(‘‘average/poor’’).Frequency tables were made of the operators opinions about overall machine comfort and about their opinions about specific parts of their machines. Chi-square was calculated between age of machine and overall comfort and between age of ma- chine and the operators’ opinion of specific parts of the machine. We assumed that if fewer than 80% of the operators rated a part of the machine ‘‘good/very good’’, im- provement of this part could contribute to a more comfortable vehicle interior. In part three of the questionnaire, the operators indicated aspects to improve machine com- fort a nd aspects they found necessary to work well with the machine. We classifiedthese aspects into categories and calculated the percentage responses.3. Results3.1. Characteristics of the populationBoth the wheel loader operators (mean age: 36.5±9.4 years) and the excavator operators (mean age: 36.3±9.3 years) who participated in this study, were experien- ced with a mean of 12.3 (±8.1) and 13.4 (±9.2) years of service, respectively. Half of the operators operate machines less than 4 years old (53% of the wheel loader and 50% of the excavator operators).3.2. Evaluation of current machine57.4% of wheel loader operators and 55.9% of the excavator operators rated the overall cabin comfort‘‘good/very good’’. It shows that operators of newer machinery (<4 years old) rated the overall cab comfort as ‘‘good/very good’’ more often than operators of older machines (≥4 years old). This was found both among wheel load- ers (χ2(1)=8.5,p<0.04) and among excavators (χ2(1)=23.0,p<0.001).Seventy-eight percent of the operators driving wheel loaders less than 4 years old, rated the comfort of their machine a s ‘‘good/very good’’.With excavator operators this figure was 81%. These results show that during recent years the experienced cab comfort of excavat- ors and wheel loaders has improved.It illustrates the opinion of the operators about specific parts of the machines less than 4 years old.Fewer aspects of wheel loaders are rated‘‘average/poor’’ by more than 20% of the operators, than excavators. Com- mon aspects which can contribute to increase of cab comfort are dashboard and dis- plays, adjustability of seats and controls, vibration and damping, noise reduction, and seat comfort. Excavator operators would also like to see improvement of climate co- ntrol, improved machine appearance, and better cab dimensions (including interior space, ingress/egress),view, and reliability.3.3. Future demandsThe participants generated 467 items desired to improve the machine’s comfort. We classified these aspects into 15 categories (see Table 2). It shows which features。
