JCB is launching the 520X, its heaviest excavator to date, and is thus targeting the established market leaders Caterpillar and Komatsu in the 50-ton segment. The new flagship is intended to strengthen the British company's position in the lucrative heavy equipment sector. As a heavy earthmoving contractor, you will have more options when it comes to large excavators – the decisive factors will be the terms for purchase and service as well as performance under full load.
