SEM 919 Motor Grader Product Parameters

• The cab is located on the front frame, and the position of the traction frame, turntable, and blade can be clearly seen, which helps the driver to more accurately control the position of the blade;
• When the waist is bent, the front wheel steering can be clearly seen to ensure the safety and accuracy of the operation;
• Adhering to Caterpillar’s ​​industry-leading joystick layout, with short stroke and appropriate spacing, the driver can operate multiple joysticks with one hand;
• The control force is light, which reduces the fatigue of the driver.
The control valve PPPC (Proportional Priority, Pressure Compensation Control Valve) specially designed for Caterpillar motor graders, the power is distributed according to demand, and the flow is distributed proportionally. The driver can operate multiple compound actions at the same time, which significantly improves work efficiency

Use variable plunger pump to reduce power consumption and hydraulic system overheating, reduce fuel consumption
The load-sensing hydraulic system provides uniform and precise blade movement and improves the flatness of the operation
The PPPC valve is equipped with a one-way lock valve to prevent the valve core from leaking when there is no hydraulic action, prevent the oil cylinder from sinking, and avoid accidental injury to personnel
Seven-hole connecting rod control system
The seven-hole linkage mechanism adopts electro-hydraulic control, which can be operated by a switch in the cab
The blade can be extended to the maximum, and the blade can be up to 90 degrees vertically when positioned at the end, which is convenient for high-back slope operations

The shovel can reach the bottom of the trench to cut and clean the overly luxuriant vegetation
·The connecting rod can be extended upwards to repair the back slope of the river bank and the back slope of the trench
The connecting rod comes standard with replaceable bushings, which can reduce service time and maintenance costs
Blade floating technology
Standard equipped with blade floating function to avoid road damage and improve work efficiency
When the user pushes the left and right lifting cylinder operating handles down to the end at the same time, the cylinder will automatically sink to the ground, and the blade floating function can be used at this time
·Especially suitable for snow removal operations
A type traction frame
The A-type traction frame is composed of two square steels, with high strength and durability, and low failure rate
The ball head can adjust the gap (adjusting the gasket) according to the wear condition, reducing the user's maintenance cost
The detachable connecting ball head is fixed with bolts, which is convenient for maintenance
Box structure front frame
The box-shaped structure design with flanges transfers the welding from the higher pressure area, improves the reliability and durability, and extends the service life of the structural parts
·The continuous top and bottom plate structure provides good consistency and strength, fully meets the Caterpillar structural design requirements, can prolong the service life of the front frame and reduce maintenance costs.
The side piping of the front frame is arranged for easy maintenance
Use self-lubricating bushings in key parts to improve reliability and reduce maintenance costs
Reasonable manipulation layout
·The operating rods are properly spaced, and the driver can operate several joysticks with one hand
·Light operating force, reducing driver fatigue
Short stroke, 40mm
