Shantui

The SHANTUI SD-16 is a 160 hp class medium crawler bulldozer. The standard operating weight is approximately 17,000 kg (varies by configuration, with wetland versions reaching up to 18,400 kg). Net power output is 120 kW / 160 HP at 1,850 rpm. Bucket (blade) capacity depends on blade type: the standard straight tilt blade offers 4.5 m³, the U-blade offers up to 5.0 m³, and the angle blade offers approximately 4.3 m³. Ground pressure is 58 kPa for the standard version. The machine measures 5,140 mm in length, 3,388 mm in width, and 3,032 mm in height. Track shoe width options include 510 mm, 560 mm, or 610 mm, with a track pitch of 203.2 mm and 37 track shoes per side.

Used SHANTUI SD-16 pricing varies significantly based on age, operating hours, condition, and market region. For relatively newer units (2024–2025 models with 200–300 operating hours, excellent condition), prices typically range from US $22,000 to $25,000 FOB China. For reference, a 2024 model with approximately 263 operating hours is commonly priced around US $25,000, while another 2024 unit is listed at approximately US $22,000. Multiple factors influence final pricing: machines with documented service history, undercarriage with 85%+ remaining life, and clean hydraulic systems command premium valuations. High-hour units (5,000+ hours) fall into lower price tiers. Prospective buyers should verify service history, inspect undercarriage wear, and request operation tests before purchase.

The SHANTUI SD-16 is offered with several engine configurations to meet different market requirements and emission standards. The most common engine options include: Shangchai SC11CB184G2B1 (net power 120 kW / 160 HP at 1,850 rpm), Weichai WD10G178E25 (meeting China-II emission standards), Weichai WP10G178E355 (net power 131 kW / 175 HP), and Cummins QSB6.7 (120 kW / 160 HP, for European markets meeting Euro III standards). All engines feature in-line, water-cooled, 4-cycle, direct injection, turbocharged diesel designs. Piston displacement is 9.726 L (Weichai/Shangchai engines). Minimum fuel consumption is 214 g/kW·h, with maximum torque of 765 N·m at 1,300 rpm.

The SD-16 features a sophisticated drivetrain and hydraulic system engineered for durability and efficiency. The transmission is a planetary gear type, power-shift unit with forced lubrication and a 3-element, single-stage, single-phase torque converter. Travel speeds are as follows: forward ranges of 0–3.29 km/h (F1), 0–5.82 km/h (F2), 0–9.63 km/h (F3); reverse ranges of 0–4.28 km/h (R1), 0–7.59 km/h (R2), 0–12.53 km/h (R3). The working hydraulic system operates at 14 MPa maximum pressure, using a gear pump with 243 L/min flow. The transmission control valve consists of five main valves: speed valve, direction valve, pressure reducing valve (maintaining first-gear clutch engagement at 1.25 MPa), pressure regulating valve (maintaining system pressure at 2.0 MPa), and quick-return valve. The steering system features hydraulically assisted wet multi-disc steering clutches and wet floating-band steering brakes. Max drawbar pull is approximately 18,000 kgf.

The SHANTUI SD-16 is built for long-term durability. Well-maintained used units commonly exceed 10,000–12,000 operating hours with routine servicing. The structural components benefit from Shantui‘s mature quality standards, with reinforced main frames using full box-type integral welded steel plate construction that maintains structural integrity over the machine’s life cycle. Fuel tank capacity is 315 L, and working hydraulic tank capacity is 110 L.

Common maintenance issues reported for SD-16 include: (1) Engine starting abnormality – after work stoppage, the engine requires extended manual fuel pumping or air bleeding before restarting. This issue has been traced to a clogged fuel tank vent causing negative pressure in the tank. The solution involves clearing the tank cap ventilation passage. (2) Main clutch slippage – under heavy load with high throttle, the dozer loses pushing power or stops moving while engine RPM remains unchanged. Diagnosed by measuring clutch pressure (standard values: ≤2.5 MPa at low throttle, 3.0±0.2 MPa at high throttle) and adjusted via the adjustment dial on the clutch assembly. (3) Hydraulic cylinder droop (cylinder drift) – normal engine support but blade drops over time. This is typically caused by insufficient spring preload on the main valve‘s one-way valve; the issue is resolved by adjusting the one-way valve preload. For used buyers, a well-maintained SD-16 with documented service history remains a reliable workhorse well beyond 12,000 hours.
