SD-22

The SHANTUI SD-22 is a 220 hp class medium crawler bulldozer, widely recognized as the next-generation upgrade of the TY220 model. The standard operating weight is approximately 23,400 kg (25,700 kg with ripper), depending on configuration. Standard bucket (blade) capacity varies by blade type: the straight tilt blade offers 6.4 m³, the U-blade offers up to 7.5 m³, the semi-U blade offers 7.0 m³, and the angle blade offers approximately 4.7 m³. Ground pressure is 77 kPa for the standard version. The machine measures 5,750 mm in length, 3,725 mm in width, and 3,395 mm in height. Track shoe width options include 560 mm (standard), 610 mm, or 660 mm, with a track pitch of 216 mm and 38 track shoes per side. Fuel tank capacity is 450 L. Minimum turning radius is 3,300 mm (approx. 3.3 m). Gradeability is 30°. Travel speeds: forward F1 0–3.6 km/h, F2 0–6.5 km/h, F3 0–11.2 km/h; reverse R1 0–4.3 km/h, R2 0–7.7 km/h, R3 0–13.2 km/h. The SD22 also features Shantui‘s patented central lubrication technology, central pressure measurement and automatic track tensioning, as well as a GPS satellite positioning system.

Used SHANTUI SD-22 pricing varies significantly based on age, operating hours, condition, and market region. A 2023 model in good used condition with standard specifications typically ranges from US $24,000–25,000 FOB China. A 2024 model with approximately 440 operating hours is commonly priced around US $44,600. A 2022 model with 868 operating hours falls in the medium price tier. A 2010 model with higher hours is valued at approximately €38,711 EUR (~US $42,000) in the European market. Multiple factors influence final pricing: machines with documented service history, undercarriage with 80%+ remaining life, and clean hydraulic systems command premium valuations. Import taxes, shipping costs (FOB vs. CIF), and local market demand also play significant roles. Prospective buyers should verify service history, inspect undercarriage wear (track rollers, sprockets, track shoes), and request operation tests before purchase. For used SD22 units in good condition, the general price range is US $24,000–45,000, with newer low-hour units at the higher end of the range.

The SHANTUI SD-22 is offered with several engine configurations to meet different market requirements and emission standards. The most common engine options include:

• Cummins NT855-C280S10 (primary option): 6-cylinder, in-line, water-cooled, turbocharged diesel, net power 162 kW / 220 HP at 1,800 rpm, piston displacement 14.010 L. Maximum torque 1,030 N·m at 1,250 rpm.

• Weichai WD10G178E25 (alternative): net power 131–162 kW / 175–217 HP at 1,800–1,850 rpm, displacement 9.726 L.

• Weichai WD12G240E306 (for some variants): rated power 175 kW / 240 HP at 1,800 rpm, displacement approx. 11.6 L.

• Shangchai SC11CB184G2B1: net power 131 kW / 175 HP at 1,850 rpm.

In terms of fuel efficiency, the SD22 demonstrates competitive performance. Minimum fuel consumption is 205 g/kW·h for the Cummins NT855-C280 engine, and 214 g/kW·h for the Weichai engines. At full-rated power (162 kW), the calculated hourly fuel consumption is approximately 33–35 L/h (162 kW × 0.205 kg/kW·h ÷ 0.85 kg/L fuel density ≈ 39 L/h theoretical). However, real-world operation reports indicate typical fuel consumption of 20–25 L/h under normal working conditions. With a 450 L fuel tank, the SD22 can support continuous operation of 18–22 hours per refueling under moderate loads. The engine meets EU Stage II emission standards (Tier 2 equivalent), making it widely acceptable in most international markets.

The SD-22 features a sophisticated drivetrain and hydraulic system engineered for durability and efficiency.

Transmission System: The SD22 utilizes a three-element, single-stage, single-phase torque converter (hydraulic mechanical torque converter) paired with a planetary gear type power-shift transmission with forced lubrication. The transmission offers 3 forward and 3 reverse gears, with smooth gear changes and optimal power distribution across various working conditions. Travel speeds are as follows: forward F1: 0–3.6 km/h, F2: 0–6.5 km/h, F3: 0–11.2 km/h; reverse R1: 0–4.3 km/h, R2: 0–7.7 km/h, R3: 0–13.2 km/h.

Steering System: The steering system features wet multi-disc steering clutches (spring-loaded, hydraulically assisted operation, mechanical separation) and wet floating-band steering brakes (foot stepping brake with hydraulic assistance). This design ensures smooth and reliable steering even under heavy loads.

Hydraulic System: The working hydraulic system operates at a maximum pressure of 14 MPa, using a gear pump with a discharge flow of 262 L/min. The system features working cylinder bores of 120 mm × 2 for blade lift cylinders, with a blade tilt cylinder bore of φ200 mm. The hydraulic tank capacity is 79 L for the main hydraulic system. The SD22 also includes an optional hydraulic winch system with a separate hydraulic circuit: pressure 1.5 MPa, oil pump flow 50 L/min, and pump type CBF-E32 gear oil pump.

The advanced hydraulic system provides precise control of the blade and other attachments, ensuring efficient power distribution and responsiveness, allowing operators to perform complex tasks with ease and accuracy.

The SHANTUI SD-22 is engineered for long-term durability, with structural components designed for a service life of 8,000–12,000+ operating hours under normal working conditions. Real-world user feedback confirms that well-maintained SD22 units have exceeded 8,000 hours with stable performance and no major mechanical accidents. The SD22 is known for its sturdy and durable body made of high-quality materials and advanced manufacturing technology, capable of stable operation under harsh conditions. New machines carry a standard 2-year/4,000-hour limited warranty, with extended coverage up to 5 years/8,000 hours available for SD22+ models.
