Boki 4552

Ideal for confined spaces!

Reform's Boki 4552 is a compact mobile excavator with a boom reach of up to 6,500 mm. With an external width of 1.22 m combined with 4 different steering modes, the Boki 4552 gives you perfect positioning, even in confined spaces. With a top speed of up to 40 km/h, the Boki 4552 can be quickly transferred between different work sites.

The reach can be selected with 3 different booms with telescopic arms; either a reach of 4,800 mm/5,600 mm or 6,500 mm is available.

The Boki 4552 has a tilting cab, which makes maintenance much easier. Inside the cab, what first catches the eye is the ergonomically designed driver seat with integrated pilot valves in the arm rests to prevent relative movements. The two-lever cross control with pilot-operated valves also makes working considerably easier.
