Motor grader SZP9220

SZP9220 motor grader, as a modern high-performance and multi-functional construction equipment, has become the main choice for various large-scale infrastructure projects due to its high-quality configuration of main components, flexible operation and reliable safety system. Whether it's high-speed highway construction, airport leveling, agricultural land reclamation or mining, the SZP9220 motor grader delivers superior cost efficiency to customers, reducing operating costs and improving project quality through high productivity.

Main Product Features

1.High quality power transmission system

The SZP9220 motor grader is equipped with a Cummins water-cooled turbocharged diesel engine, which is powerful and reliable. It is able to maintain stable performance even under difficult operating conditions, ensuring high operating efficiency. The equipment uses a German-made ZF torque converter and gearbox. The rational design of the gearbox with six forward gears and three reverse gears perfectly meets various needs in working and transporting, and the transmission efficiency and smooth operation are far superior to similar products in the industry.

2.Stable and reliable traveling and steering system

The drive axle is equipped with a freewheel differential with anti-slip function and a high-strength chain drive with tandem reduction gear.

In combination with the articulated front axle with tilting wheels, this significantly improves the equipment’s cross-country ability and stability on

difficult terrain. The central articulated steering system with rotating front wheels allows for

The offset movement of the entire machine makes working in narrow spaces and precise alignment more convenient and greatly reduces the difficulty of operation.

3.Efficient and flexible control system and hydraulic system

The design uses a classic operating mechanism with a pendulum lever and is standardly equipped with a maintenance-free device with

roller plate, which reduces subsequent maintenance costs. The dual blade tip control function allows for flexibility

 adjust the cutting angle depending on the quality of the soil, adapting to different working conditions. The hydraulic system is equipped with two 

sets of HUSCO five-way valves, the blade lift is carried out using an imported hydraulic equalizing valve, and the first in 

The industry's patented hydraulic pin puller makes operation more precise and response faster.

4. Comprehensive security and monitoring guarantee

The equipment is equipped with four disc service brakes with calipers on the rear wheels and mechanical internal expanding

parking brakes. The dual braking system provides increased safety during intensive use. Electro-hydraulic

The control, combined with a comprehensive instrumental monitoring system, allows you to monitor the condition of the equipment in real time.

time and warn in advance about potential malfunctions.

Main competitive advantages

The main advantage of the SZP9220 motor grader is its “customizability + trouble-free operation throughout the entire

life cycle." All major components are manufactured by the world's leading manufacturers, tested under harsh operating conditions, and 

Mean time between failures significantly exceeds industry standards, which significantly reduces losses due to breakdowns. Front blade and

The rear ripper can be installed as an option, which allows for multifunctional integrated operations such as

leveling, trenching, bulldozing and loosening. One piece of equipment can meet the needs of several technological

processes, reducing the cost of purchasing equipment.

Compared with traditional motor graders, the optimized design of the hydraulic system and working mechanism greatly improves

precision of work, which is especially important for high-precision site alignment; wide use of maintenance-free components in combination with

The convenient design for maintenance significantly reduces maintenance costs and downtime, and improves

equipment availability factor.

Typical Application Scenarios

Due to its versatility and high adaptability, the SZP9220 motor grader is widely used in various key infrastructure projects:

During the construction of high-quality roads and railways, it carries out such important work as leveling the roadbed and

slope planning, laying a solid foundation for subsequent paving; in large-scale projects such as airports,

ports and dams, he carries out leveling of large areas, digging canals and other works, ensuring the quality and deadlines for project completion;

at industrial facilities, during reclamation of agricultural land and development of mineral deposits it satisfies

diverse needs such as shaping terrain, loosening soil and clearing snow, adapting to different types of terrain and

working conditions.

Choosing the SZP220 motor grader provides customers with multi-faceted efficiency improvements: firstly, work productivity is greatly improved, multi-functional integrated design reduces equipment switching time, and precise control reduces the number of reworks, allowing the project to be completed ahead of schedule; Secondly, operating costs are reduced, high quality core components improve fuel efficiency, maintenance-free design reduces maintenance costs, extends equipment life and reduces total cost of ownership; thirdly, the controllability of project quality increases, and high accuracy of work ensures compliance with strict standards, increasing the percentage of project acceptance; fourthly, work becomes more convenient and safe, the ergonomic design of controls reduces the requirements for operator qualifications, and a perfect safety system reduces risks during operation.
