The first mini-excavator was designed by the Japanese company Yanmar in 1968. The serial production of Yanmar began in already in 1971. The first mini-excavators were equipped with metal tracks and a large swivel platform that impeded the operation of the machine in cramped conditions. In 1979, Yanmar mini-excavators received rubber tracks, and in 1994 a machine was created with a zero turning radius working platform. When rotating the platform, such a mini-excavator does not protrude beyond the dimensions of the chassis, so it can work while standing close to the obstacle. The emergence of mini-excavators with a zero turning radius was the impetus for the success of this class of machines in the world market. Mini-excavators became the founders of all mini-equipment. Nowadays, mini-bulldozers and mini-loaders are also widely represented on the world market.
Therefore, mini-excavators use water services and gas workers in urban areas for laying pipes, signalmen and power engineers for laying cables, road services for installing fences and road signs, landscapers for landscaping yards and planting trees, emergency rescue services in case of emergency (even possible work using radio control), builders for the largest amount of work (for example, the construction of foundations for country houses), archaeologists for excavations.
For each specific type of work, the necessary working equipment is installed on a mini-excavator. For digging, planning, laying pipes and cables, a bucket of optimal width is installed, and after laying the cable, it is possible to use a hydraulic installation. All modern mini-excavators are equipped with a hydraulic drive and are able to work with all types of attachments.
Having successfully started the mass production and sale of mini excavators in Japan in 1971, in 1979 Yanmar entered the world market. But during this period, sales in Europe and America were not at all significant. The change in situation began in 1994, when models appeared with a zero turning radius of the platform. Since then, sales of mini excavators in Europe and America have begun to grow steadily. The real boom in sales of mini excavators came in 1999-2005. Below is the sales schedule for mini excavators in the USA and Europe.
