Shantui SD22F Winch Bulldozer is a purpose‑built forestry‑spec crawler dozer with rear mechanical winch, engineered specifically for logging, timber haulage, road construction, and recovery operations in dense forest, steep terrain, and remote woodland environments. Factory‑configured with heavy‑duty winch + ROPS/FOPS forestry cab protection — the industry benchmark for 220‑hp class forest dozers.

Powered by Cummins NT855‑C280S10 inline‑6 turbo diesel (14.01 L displacement), delivering 162 kW (220 HP net) @ 1800 rpm — gross 175 kW / 235 HP — with 1030 N·m max torque @ 1250 rpm, offering immense lugging power for winching and heavy pushing while maintaining fuel efficiency. Meets China Stage III / Tier 2 emissions.

Integrated rear mechanical winch — core feature: bare‑drum pull 350 kN, full‑drum pull 220 kN, line speed up to 15.9 m/min, Ø28 mm × 70 m steel cable. Designed for skidding logs, pulling heavy loads, and self‑recovery on steep slopes — essential for forestry and difficult terrain.

Proven 3‑speed forward / 3‑speed reverse planetary powershift transmission with torque converter: F1 0–3.6, F2 0–6.5, F3 0–11.2 km/h; R1 0–4.3, R2 0–7.7, R3 0–13.2 km/h. Wet steering & brake controls; 30° gradeability; max traction 450 kN.

Forestry‑optimized cab & structure: ROPS/FOPS integrated canopy/cab with falling‑object protection, reinforced guarding, panoramic visibility, ergonomic controls. Heavy‑duty undercarriage with 610 mm wide track shoes (low ground pressure ~64–66 kPa), excellent flotation on soft forest ground.

Blade options: Straight‑tilt 6.4 m³, Angle 4.7 m³, Semi‑U 7.0 m³, U‑Blade 7.5 m³ — high‑capacity forestry blade clears brush, grades roads, and handles large timber piles. Optional single‑tooth or multi‑tooth ripper.

Operating weight: 24 700 kg (with winch & forestry cab); robust, low‑maintenance design — built for long hours in harsh, remote forest conditions.
