SEM 822D Bulldozer for Construction Earthmoving | Chengda
The SEM 822D is a track-type bulldozer built for earthmoving, mining and road construction. Its WD10G178E25 engine delivers 175 kW at 1,800 r/min, and the 26,520 kg operating weight with 71.2 kPa ground pressure keeps the machine stable on tough ground. An electronically controlled hydrostatic drive with stepless 0-10 km/h travel, plus a 6.4 m³ SU blade and adjustable parallelogram ripper, handles dozing and ripping in one pass. Six configurations — STD, LGP, CH, DS, WH and FR — cover everything from wet land to coal yards and desert work. Send your working condition for a tailored quote.

26,520 kg Operating Weight | 175 kW Engine Power | 6.4 m³ Blade Capacity |
The SEM 822D bulldozer handles earthmoving on highway and railway construction sites, open-pit mines, power plants, coal yards and airport projects. Its SU/S blade with 6.4 m³ capacity and a 570 mm maximum cutting depth moves bulk material efficiently, while the parallelogram ripper reaches 860 mm deep to break compacted ground before grading. With 30° gradeability and 400 mm minimum ground clearance, it keeps working on uneven job sites and steep access ramps.
Six configurations let one machine family cover very different ground conditions: the LGP wetland version runs on 915 mm track shoes with ground pressure down to 43.0 kPa for soft, waterlogged soil, the CH coal version carries a 9.2 m³ blade for coal stockpile handling, and the WH sanitation version uses a 12.7 m³ blade for landfill spreading and compaction. Desert, forestry and standard versions cover sand control, land clearing and general municipal work. A 175 kW engine paired with an electronically controlled hydrostatic drive gives stepless 0-10 km/h travel, so operators can match speed to the load instead of shifting gears.

175 kW Engine for Sustained Dozing The WD10G178E25 engine is rated 175 kW (ISO 14396) at 1,800 r/min, providing the drawbar pull needed for continuous earthmoving. A 26,520 kg operating weight keeps the blade loaded through hard cuts. | Stepless Hydrostatic Drive from 0 to 10 km/h The dual-path, closed-loop electronically controlled hydrostatic transmission gives stepless speed control from 0 to 10 km/h in forward and reverse. Hydrostatic steering and wet multi-disc brakes hold the machine on grades up to 30°. |
Six Configurations to Match the Job Site Choose STD, LGP, CH, DS, WH or FR builds: operating weight ranges from 26,520 kg (STD) to 28,560 kg (WH), and ground pressure from 41.7 kPa (DS) to 76.5 kPa (FR). Each version is factory matched to its blade and undercarriage. | Blades from 5.5 m³ to 12.7 m³ with a 860 mm Ripper Blade capacity (ISO 9246) runs from 5.5 m³ (LGP, DS) to 12.7 m³ (WH), including 6.4 m³/5.8 m³ (STD), 9.2 m³/7.5 m³ (CH) and 8.7 m³ (FR). The parallelogram ripper cuts to 860 mm with adjustable shank positions. |
19 MPa Hydraulics with Pilot Control A closed-center, pilot-controlled hydraulic system runs at 19 MPa with a gear pump, keeping blade lift, tilt and ripper response consistent through the working cycle. | Undercarriage Matched to Ground Conditions Track shoe width runs from 560 mm (STD) to 915 mm (LGP, DS, WH), with 40 or 45 shoes and 7 or 8 track rollers per side plus 2 carrier rollers. Minimum ground clearance is 400 mm. |

What is the operating weight of the SEM 822D bulldozer?
The operating weight is 26,520 kg with the SU blade and ripper fitted. Different configurations range from 26,520 kg to 28,560 kg depending on blade and undercarriage setup.
What engine powers this construction bulldozer?
It uses the WD10G178E25 engine rated at 175 kW at 1,800 r/min under ISO 14396. This gives enough power for heavy earthmoving, mining and road work.
Which configurations are available for the SEM 822D?
Six versions are offered: STD standard, LGP wetland, CH coal, DS desert, WH sanitation and FR forestry. Each one matches a different job site and blade type.
How much material can the standard blade move?
The standard SU/S blade has a capacity of 6.4m³ or 5.8m³ under ISO 9246. Blade width is 3,660mm or 3,800mm including the cutting edges.
Can this sem bulldozer work on soft or wet ground?
Yes. The LGP wetland version uses 915mm track shoes and lowers ground pressure to 43.0kPa. That keeps the dozer stable on soft soil and wet sites.
How deep can the ripper penetrate?
The parallelogram ripper reaches a maximum digging depth of 860mm, with the shank position adjustable. Maximum lift height ranges from 615mm to 742mm depending on configuration.
