Product Description
China EXW Price SEM(CAT OEM) 190hp 220hp Motor Grader (SEM921)
Cat Homemade Rear Axle
- Improve bearing arrangement, distribute load reasonably, and increase service life.
- Caliper disc brakes, 20% better performance and more reliable.
- Four-planetary gear arrangement final drive, stronger carrying capacity.
- External brake for easy maintenance.
- No grease requirements, saving time, effort and money.
Seven-hole connecting rod control system (optional)
- Electro-hydraulic control seven-hole linkage mechanism, the hole position switching can be completed in the cab.
- Using the right hole position ensures that the blade can reach the bottom of the trench when clearing overgrown vegetation in the trench.
- By adjusting the hole position of the connecting rod, the angle between the blade and the ground can be better adjusted, which is convenient for repairing the drainage ditch and the back slope of the river bank. When positioned at the end of the hole, the blade can reach 90 degrees perpendicular to the ground, which is convenient for high backslope operations.
- Standard replaceable bushings in connecting rod bores for easy maintenance and repairs, reducing service time and maintenance costs.
Load Sensing Hydraulics
- The PPPC (proportional priority, pressure compensation) control valve specially designed by Cat for motor graders, the power is distributed according to the demand and the flow is distributed proportionally, which ensures that the driver can operate the machine to complete multiple compound actions, which significantly improves the work efficiency.
- Adopt variable piston pump to reduce energy loss, reduce heat generated by hydraulic system, and reduce fuel consumption.
- Load-sensing hydraulics provide predictable, precise implement movement for improved job quality and productivity.
- The PPPC valve has a built-in locking valve to prevent internal leakage of the valve core, maintain the position of the machine when there is no hydraulic operation, and ensure the work quality; prevent the machine from moving unexpectedly and avoid accidental injury to personnel.
A-type tow frame
- A-type traction frame is composed of two square steels, with good durability, long service life and low failure rate.
- The ball head can adjust the gap (adjusting spacer) according to the wear condition, reducing the user maintenance cost.
- Removable connecting ball head bolted for easy replacement.
Box structure front frame
- Flanged box structure design keeps high stress areas away from the weld, improving reliability and durability, extending the life of the structure.
- Continuous top and bottom plate structure provides good consistent strength, fully complying with Cat structural design requirements, can extend front frame life and reduce operating costs.
- The piping on the side of the front frame is arranged for easy maintenance.
- Self-lubricating bushings are used in key parts to improve reliability and reduce maintenance costs.
Reasonable manipulation layout
- Adhering to CAT’s industry-leading joystick layout, the short travel and proper spacing allow the driver to operate multiple joysticks with one hand.
- Light operating force, reducing driver fatigue.
Spacious and comfortable cab
- The cab is located on the front frame, and the position of the drawbar, turntable and blade can be clearly seen, which is helpful for the driver to control the position of the blade more precisely.
- Tall and spacious (1.9 meters high), can stand operation, 30% larger volume.
- The front wheel steering can be clearly seen when bending over, ensuring the safety and accuracy of the operation.
