Due to the spread of small-sized loaders with on-board swing system (SLOS), it has become necessary to determine the level of their technical development. To understand the set task, a review of small-sized loaders, their classifications, performance parameters and implements was made. Modern SLOS manufacturers were analysed; their design features; main operating parameters: engine power, load capacity, speed and vehicle weight. An analysis of recent papers describing SLOS performance was conducted. It should be noted that most of them consider specific workflow processes, design features that do not reflect the full range of such machines. To solve this problem, a statistical analysis of theSLOS nomenclature data was performed depending on the classification features and performance indicators. This article presents the assessment of the impact of SLOS performance parameters and classification features on their level of technical development. Based on statistical data, the regression equations of the dependences were obtained: engine power on load capacity; loader weight on load capacity; dependences of performane parameters were plotted. General trends in the technical development of small-sized loaders were established. The vast majority of manufacturers focus on the production of medium-capacity loaders, as they are in the greatest demand. The analysis of the graphs suggests that in the future production of small-sized loaders with the load capacity of up to 1.5 tons, engine power of 60-70 kW and weight of up to 5 tons will increase. We can also predict growing production of compact SLOS with the load capacity of up to 0.5 tons, engine power of 20-30 kW and weighing up to 2 tons, which are widely used in urban landscaping. With the help of the present paper we can predict development trends, establish weaknesses of modern SLOSs and avoid competition when designing new loaders. |
