14 Ton Road Construction Equipment Sem918 Motor Grader

Product Introduction

SEM918 motor grader is mainly suitable for road construction, municipal construction, water conservancy construction, airport and other applications. This upgrade not only significantly improves the adaptability to working conditions, production efficiency, operation comfort and serviceability, but also further reduces customer The comprehensive cost of use is deeply loved by customers.

Product Features

1. Shangchai SC7H National III emission engine. Electric control, high voltage common rail. Four-valve structure, supercharging and intercooling, more complete oil-air mixing, lower fuel consumption, and more environmentally friendly emissions.

2. 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.

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

4. The working hydraulic system adopts the variable plunger pump of an internationally renowned brand, which is reliable and durable. Load-sensing hydraulics provide predictable cylinder travel speeds for leveling with greater precision.

5. The A-type traction frame adopts a box structure, which is 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.

6. 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.

7. 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.
