Description

The world’s most powerful floor grinding and polishing machines

The Expander range of floor grinders has many characteristics which allow the operator to achieve the ultimate FLAT FLOOR. With a fixed planetary gear-driven head that works to grind all flooring surfaces flat, to the machine design which focuses all of the weight and grinding pressure over the top of the working section of the machine. In particular, the Expander 1000 features one metre (1000mm) wide working area with six planetary heads, which along with its 1.35-tonne weight delivers the ultimate flat floor.
Many machines available on the market are designed with a floating grinding head, this allows the machine to follow the contours of the floor and can at times leave a ‘wavy’ appearance to the floor. The combination of the floating head and lighter machine weight reduces the grinding ability of the machine to produce perfectly flat floors.
