Product Description 

The Brand New Shantui SD22 Bulldozer is engineered as a robust hydraulic crawler-type earthmoving machine that combines a proven mechanical layout with modern hydraulic control. Built for demanding construction, mining, landfill and water conservancy projects, the SD22 delivers consistent pushing force, precise blade control and long-term durability. With engine options from Cummins or Weichai, the SD22 balances global parts availability with fuel-efficient operation to suit varied regional needs.

Shantui designed the SD22 around three core principles: dependable force transmission, structural resilience, and operator-centered control. The integration of a hydraulic transmission with planetary gear technology ensures the engine’s output is converted into steady track torque with minimal parasitic loss. The mainframe and chassis are engineered to resist torsional stresses encountered when working on uneven or rocky ground, which reduces wear on key components and lowers the risk of unplanned downtime.

Buyers can choose between the Cummins NT855-C280S10 and the Weichai WP12G240E306 engines, both rated at 175 kW at 1800 rpm. The Cummins choice is particularly advantageous where international parts networks and service familiarity are priorities. The Weichai alternative provides strong fuel economy characteristics and proven endurance in heavy-stop applications. Both engines are matched to a hydraulic drive and planetary final drives for reliable torque delivery.

The SD22’s advanced hydraulic system adapts speed and torque automatically to the external load, maintaining momentum during heavy pushing and reducing the need for frequent manual gear changes. The hydraulic circuits are sized to support rapid blade response and consistent track speed under varying resistances. Centralized monitoring of hydraulic pressures, oil temperature and electrical systems is standard, enabling preventive action before minor issues escalate.

• Smooth power delivery for continuous dozing and ripping operations.
• Automatic torque adjustment reduces operator fatigue and improves productivity.

• Optimized hydraulic cooling options for high ambient temperatures.

The mainframe is reinforced to resist twisting and bending forces that occur during heavy-duty earthmoving. The undercarriage uses modular components that simplify maintenance and shorten downtime for track and roller replacement. Track shoe width options (560 / 610 / 660 mm) allow customers to configure ground pressure and traction according to application: wider shoes for soft or swampy ground, standard widths for general construction.

A hexahedral cabin layout provides excellent forward, lateral and rear visibility to assist in precise blade placement and safe manoeuvring. Controls are ergonomically arranged to reduce reach and repetitive motion, while sound insulation helps reduce cabin noise for longer, more focused shifts. The SD22’s design emphasizes operator comfort to maintain productivity on long projects and in harsh conditions.

The SD22 supports multiple blade types (straight tilting, angle, U-shaped and semi-U) and offers a blade capacity of 4.6 m³ in standard configuration. This flexibility lets contractors tailor the machine for bulk material movement, finish grading, or specialized clearing tasks. A rear ripper option (single- or three-shank) converts the dozer into an efficient ground-preparation tool suitable for frozen ground, compacted layers or root removal.

Meeting EU Stage II emissions requirements, the SD22 is suitable for regions with basic emissions regulation and can be further configured with local after-treatment packages if required by stricter jurisdictional standards. The machine’s fuel efficiency and large 450 L tank are designed to reduce refueling frequency and lower operational interruptions at remote sites.

• Sustained pushing power: The combination of a turbocharged 175 kW engine and an efficient hydraulic transmission enables sustained traction and pushing force when moving heavy loads or clearing materials.
• Blade precision: Hydraulic responsiveness and multi-blade compatibility support both bulk dozing and fine grading tasks, reducing the need for secondary machines.

The SD22 is positioned to deliver a competitive total cost of ownership through three channels: reliable core components that demand fewer major repairs, a large fuel tank that minimizes refuel interruptions, and a supplier network that supports parts availability. Selecting an appropriate engine option (Cummins for parts universality, Weichai for fuel efficiency) enables buyers to match lifecycle costs with their operational priorities.

Shantui provides environment-specific variants of the SD22 to adapt to site challenges without compromising the machine’s baseline capability. Primary variants include:

• SD22 (Standard) – Balanced track width and blade for general construction and infrastructure.
• SD22S (Swamp) – Wider track shoes and reduced ground pressure for wetlands and soft soils.
• SD22F (Forest) – ROPS canopy and winch options tailored for logging and forestry tasks.
• SD22D (Desert) – Enhanced cooling and filtration to handle high-temperature, high-dust environments.

An onboard monitoring system alerts operators to deviations in oil pressure, water temperature and voltage. These alerts facilitate preventive maintenance—catching issues at an early stage before they require major repair. Implementing scheduled service based on monitoring data improves uptime and can extend the useful life of hydraulic and engine components.

When procuring heavy machinery, the supplier’s logistics capability is as important as the machine specification. Confirm that the vendor maintains reliable stock, clear documentation, and experience with international transport methods such as Flat Rack and RORO. ZW Group carries out pre-shipment inspections covering hydraulic lines, engine performance and track tension, and prepares accurate commercial documentation to support customs clearance.

The standard delivery time for the Brand New Shantui SD22 Bulldozer is 15–20 days, subject to final confirmation at time of order. Because supply capacity is robust (10,000 units per month), ZW Group can usually accommodate larger fleets or staged deliveries to support phased projects.

Frequently Asked Questions (Expanded)

Below are practical answers to common questions to help project managers make an informed purchase decision.

Q1: What distinguishes the Cummins and Weichai engine options?

Both engines deliver the rated 175 kW power output at 1800 rpm. Cummins is preferred where established global parts distribution and service familiarity are priorities. The Weichai option is a solid choice where fuel economy during long steady-state operations is important. The choice should be guided by local service network and fuel quality considerations.

Q2: Can the SD22 be fitted with a rear ripper?

Yes. The SD22 supports both single-shank or three-shank rear ripper configurations, enabling effective loosening of compacted or frozen ground and increasing dozing efficiency in preparation tasks.

Q3: What is the supply capacity and typical delivery time?

The manufacturer’s supply capacity is listed at 10,000 units per month. Standard delivery time is 15–20 days; final lead times should be confirmed at order placement based on inventory and shipping schedules.

Q4: Are English operation and maintenance manuals provided?

Yes. ZW Group supplies full operation and maintenance manuals in English to support operator training and maintenance planning.

Q5: What payment terms are accepted?

Common payment methods include T/T (Telegraphic Transfer) and L/C (Letter of Credit). Confirm terms with ZW Group when requesting a formal quotation.
