Buy or hire the SY26U if...
The SANY SY26U is a 2.6 tonne mini excavator positioned as a value alternative to the established Kubota, JCB and Takeuchi machines in the same size class, sold in the UK through a small number of appointed dealers. SANY's UK presence is newer and thinner than the market leaders, so buyers weigh the lower purchase price against a less mature parts and resale network. It is more often bought outright by owner-operators than stocked in volume by the large national hire fleets.
