It covers major models such as crawler excavators, wheeled excavators, motor graders, backhoe loaders, skid steer loaders, wheel loaders and bulldozers. Featuring powerful power output, flexible operation and high working efficiency, they are capable of handling complex working conditions including earth-rock excavation, site leveling, material handling and pushing & backfilling, and are widely applied in infrastructure construction, mining, farmland water conservancy and other earthwork projects.
The crawler excavator combines practicality and professionalism. The whole body is integrally welded with high-strength structural steel, featuring outstanding impact resistance and deformation resistance. It is adaptable to complex and harsh working environments such as mines and construction sites, effectively extending the full life cycle of the equipment. Equipped with wear-resistant rubber tracks or steel tracks, it boasts a large ground contact area and strong grip. It can travel flexibly on complex terrains including soft ground and mountainous areas, while efficiently reducing ground pressure to avoid excessive damage to the construction site, making it suitable for a wide range of complex working scenarios.
Adopting a high-strength wheeled chassis design, the machine features a compact body and flexible steering, enabling rapid relocation between job sites. It can complete short-distance transfers without special transportation equipment, greatly saving transit time and logistics costs. The whole body is integrally welded with high-strength structural steel, delivering excellent impact resistance and deformation resistance. Key parts are reinforced to adapt to various working environments such as municipal construction sites, highway sidelines and urban-rural roads, balancing outstanding operation stability and equipment durability.
Equipped with a high-precision blade adjustment system, it enables accurate control of the blade’s lifting, tilting and side shifting. It delivers high leveling accuracy, effectively ensuring the flatness and gradient of the working surface meet standard requirements and eliminating potential hidden troubles in subsequent construction. The blade is made of high-strength wear-resistant alloy with specially treated cutting edge, featuring excellent wear resistance and impact resistance. It performs uniform and efficient scraping, adapts to operation with materials of different hardness, and extends the service life of wearing parts.
Adopting heavy-duty engineering tires, it features strong load-bearing capacity and outstanding wear resistance, suitable for various road conditions such as paved roads and gravel roads. The whole machine body is integrally welded with high-strength structural steel, with key parts reinforced. It delivers excellent impact resistance and deformation resistance, and can adapt to complex and harsh working environments.
Compact in body size and short in wheelbase, the machine enables in-situ steering with a small turning radius. It can easily access narrow spaces unreachable by large equipment, perfectly adapting to various complex and confined working scenarios. It can be optionally equipped with a variety of attachments including bucket, breaker, grapple, ripper and sweeper. Quick attachment switching allows it to perform multiple operations such as loading, breaking, sweeping, scarifying and grabbing. One single machine meets diverse construction needs and improves overall economic benefits.
Equipped with a loading bucket at the front and an excavating device at the rear, the machine can quickly switch between excavation and loading modes without disassembly. It meets the demands of earthwork excavation, trench digging, material loading and transportation, greatly improving construction efficiency.
Small Electric Loader focuses on the core demands of environmental protection and short-distance operation. Positioned with zero emission, low noise, compact size and high flexibility, it is widely applicable to indoor warehouses, municipal greening, small construction sites, farms, logistics parks and other scenarios. Adopting pure electric drive, it balances operating efficiency and environmental standards. As an optimal small-sized equipment for green construction in the new era, it helps customers achieve low-carbon operation.
Bulldozers are mainly used for the pushing, leveling, excavation and cleaning of materials such as soil, sand, gravel and construction waste. They are widely applied in diverse scenarios including mines, construction sites, highways, railways, farmland water conservancy and airport construction. Capable of large-area earth moving and site leveling, they also adapt to foundation trimming on complex terrains. Combining high working efficiency with precise construction performance, they provide strong support for the progress of subsequent engineering projects.
