HBXG – other models: crawler dozers from the Chinese maker in Xuanhua outside the named ranges, SD-7 to TY165-2, Cummins engines, 81.1 to 246 kW, 12,000 to 40,000 kg
HBXG, headquartered in Xuanhua in Hebei province, is a Chinese maker of crawler dozers. This page gathers the models the register could not assign to a named range: SD-7, SD-7 LGP, SD-8, TY120A and TY165-2. The SD and TY abbreviations denote different ranges within the HBXG programme, and LGP, as with other makers, marks a version with a wider track undercarriage and lower ground pressure for soft terrain.

The register lists here 5 versions with 81.1 to 246 kW of power, six-cylinder diesel engines of 8,300 to 14,001 cm³ displacement, including variants of the Cummins NTA855 range, torques of 569 to 1,627 Nm, operating weights of 12,000 to 40,000 kg and rated speeds of 1,900 to 2,100 rpm.
Crawler dozers in this weight class are used in earthworks, mining and landfill construction to push material, level ground and prepare roads for heavy transport vehicles; HBXG supplies chiefly the Chinese domestic market along with export markets in Asia, Africa and South America with comparatively affordable large machines.
When buying used, what counts is the condition of the track undercarriage, the roadwheels and the track shoes, the tightness of the blade's lift and tilt cylinders, the condition of the final drives, engine hours, and rust on the frame; spare parts for HBXG machines run mostly through Chinese export trade.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
