Cheap 170HP Motor Graders Sem917

Product Introduction

SEM917 motor grader adopts load-sensing hydraulic system, which is easy and convenient to operate. Well-designed Caterpillar-made transaxles and counterbalance boxes help ensure equipment uptime and lower customer operating costs. It has significantly improved the adaptability of working conditions, production efficiency, operating comfort and serviceability, and further reduced the comprehensive use cost of customers, which is deeply loved by customers. It is mainly suitable for road construction, municipal construction, water conservancy construction, airport and other applications.

Product Features

1. The proportional priority and pressure compensation control valve specially designed by Caterpillar for motor graders is matched with the load sensitive variable piston pump. The pressure and flow of the hydraulic system perfectly match the needs of the work, saving energy and high efficiency while providing the operator with an excellent control experience.

2. Modular design of the rear axle, imported automatic forced locking differential, oil bath forced lubrication of the sprocket shaft and bearings, the entire rear axle does not need to be filled with grease, and the chain tension does not need to be adjusted.

3. Adhering to Caterpillar’s industry-leading joystick layout, the stroke is short and the spacing is appropriate, and the control force is light. The driver can operate multiple joysticks at the same time with one hand.

4. Hang Gear electronically controlled fixed-shaft gearbox. Self-made motor grader drive axle, modular design, four-planet wheel side reduction mechanism, oil bath forced lubrication of sprocket shaft and bearing. Grease-free lubricated rear drive axle, heavy-duty tension-free drive chain. The external caliper disc brake has a shorter braking distance, and the brake friction plate is common to SEM loaders and easy to replace. The new structure of the front drive shaft is adopted to effectively reduce the noise.

5. Optimize the pipeline of the intercooler, and the air intake resistance is lower. The hydraulically driven fan can adapt to higher ambient temperature requirements.

6. Adopt box structure, reliable and durable. The connecting ball head of the traction frame adopts a detachable design and is fixed to the traction frame by bolts, which is easy to replace and low in cost. Optimize the tooth shape and machining accuracy of the slewing ring gear, and the operation is more stable and the service life is improved. Improve the strength of the 7-hole connecting rod bushing. The bushing of the side shift cylinder is upgraded to alloy material, which is more wear-resistant and has a longer service life.

7. The wiring harness layout of the electrical system is optimized, making installation, inspection and maintenance more convenient. Upgrade Nordic (Nordic) work lights, the quality is more reliable. Maintenance-free battery maintenance is more convenient.

8. It adopts a multi-directional adjustable shock-absorbing seat with arm rest and headrest, and the adjustable steering column provides the driver with a first-class driving environment. The hydraulically driven fan not only saves energy but also reduces noise. The noise at the driver’s ear is as low as 81 decibels, which is 5% lower than the industry standard, further improving the driver’s operating comfort. The cab is equipped with air conditioner as standard, the number of air outlets of the air conditioner is increased, the air volume distribution is more uniform, and the right control layout is optimized to improve comfort.
