Boki 6552

The most powerful Reform mobile excavator!

The Boki 6552 is the most powerful Reform mobile excavator. With its strong 4-cylinder 98 hp VM diesel engine, the Boki 6552 is a real powerhouse. Equipped with a powerful hydrostatic drive for a maximum speed of up to 40 km/h, rapid changes of site are possible. The Boki 6552 also sets the bar in terms of working performance, and can achieve a reach of 6,500 mm or even 7,000 mm with a telescopic boom. The standard version has a reach of 5,400 mm. Equipped with a powerful load sensing hydraulic system, the Boki 6552 achieves very high excavation performance.

The short wheelbase of 1,640 mm and the 4 different steering modes ensure optimum manoeuvrability.

The cab is clearly and ergonomically designed and offers excellent all-round view. The safety cabin is ROPS- and FOPS-approved. The split driver's door and the hinged front window increase comfort. The cushioned driver seat with joysticks in the arm rests prevents relative movements and takes the driver’s anatomical needs into account.
