Product Description
Proven performance meets Chinese engineering excellence in this 55-ton hydraulic excavator from XCMG's premium lineup. Operating since 2021, this XE550DK demonstrates the durability and reliability that contractors demand from heavy-duty earthmoving equipment. Powered by a robust Perkins 2206 III N engine delivering 309.5 kW at 2100 rpm, this workhorse maintains consistent output across demanding applications from mining operations to large-scale construction projects.
Built to withstand rigorous site conditions, the machine features a 51,200 kg working weight with optimized ground pressure of just 88 kPa, ensuring stability without compromising mobility. Dual main pumps supply 720 L/min combined flow for responsive hydraulic performance, while the 6,550 mm boom and 2,550 mm arm provide exceptional reach and breakout force—330 kN bucket digging force and 255 kN arm digging force handle tough materials efficiently.
