Product Description
Rated at 20 t on a 33.5 m four-section telescopic boom, the QY20G feeds its boom, winch, and slewing circuits from a load-sensing, variable-displacement axial piston pump — proportional output at any throttle, with no lag when the load swings out.
- Engine: turbocharged six-cylinder diesel on a 6×4 carrier chassis
- Hydraulics: load-sensing main pump, pilot-operated proportional valves, isolated swing and winch circuits
- Boom: 33.5 m four-section, single-cylinder sequential telescoping
- Jib: 8.5 m lattice offset extension for extended reach
- Outriggers: fully hydraulic H-pattern, individually adjustable
- Slewing: 360° continuous through planetary gear reduction, free-swing option
XCMG's QY series holds its reputation in the field, not on the spec sheet: high-tensile welded boom sections, hardened pins, and a hydraulic layout that maintains pressure across long shifts. This 2020 unit is held in Shandong, China, and is available for inspection and documentation review.
