Product Description

 

Homemade Rear Axle

• Improve the bearing arrangement, distribute the load reasonably, and increase the service life
• Caliper disc brakes for 20% better performance and more reliability
• Final drive with four planetary gear arrangement, stronger carrying capacity
• External brake, easy maintenance
• No need for grease injection, saving time, labor and money

Seven-hole connecting rod control system (optional)

• The electro-hydraulic controlled seven-hole linkage mechanism can complete hole position switching in the cab
• Using a suitable hole position can ensure that the blade can reach the bottom of the ditch when clearing the overgrown vegetation in the ditch
• Through the adjustment of 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 hole position, the blade can reach 90 degrees perpendicular to the ground, which is convenient for high back slope operations
• Replaceable bushings are standard in the connecting rod bore for easy maintenance and repair, reducing service time and maintenance costs

Blade floating function

Standard blade floating function reduces work difficulty and improves work efficiency

• When the double oil cylinders are floating at the same time, the blade relies on its own gravity to cling to the ground and move up and down with the undulation of the ground to protect the hard road. For snow removal and road rubbish removal
• The single lifting cylinder is floating, which can make one side of the blade close to the hard working surface, and the other side of the lifting cylinder is used to control the inclination of the blade

Load Sensing Hydraulics

• The PPPC (Proportion Priority, Pressure Compensation) control valve specially designed for motor graders distributes power according to demand and flow according to proportion, ensuring that the driver can operate the machine to complete multiple compound actions and significantly improve work efficiency
• Variable displacement plunger pump is used to reduce energy loss, reduce heat generated by the hydraulic system, and reduce fuel consumption
• Load-sensing hydraulic system provides predictable, precise implement movement for improved work quality and productivity
• The PPPC valve has a built-in lock valve to prevent internal leakage of the valve core, maintain the position of the machine tool when there is no hydraulic operation, and ensure the quality of work; prevent accidental movement of the machine tool and avoid accidental injury to personnel

 

Type A traction frame

• Type A traction frame is composed of two square steels, which has good durability, long service life and low failure rate
• The ball head can adjust the clearance (adjustment gasket) according to the wear condition, reducing the user's maintenance cost
• The detachable connection ball head is fixed with bolts for easy replacement

Box structure front frame

• The box-type structure design with flange keeps the high-stress area away from the weld seam, which improves reliability and durability and prolongs the service life of structural parts
• The continuous top and bottom plate structure provides good consistent strength and fully complies with the design requirements of structural parts, which can prolong the life of the front frame and reduce the cost of use
• Pipeline layout on the side of the front frame, easy maintenance
• Self-lubricating bushings are used in key parts to improve reliability and reduce maintenance costs

Reasonable manipulation layout

• Inheriting industry-leading standard joystick layout, short travel and proper spacing allow the driver to operate multiple joysticks with one hand
• Light control force, reducing driver fatigue

Spacious and comfortable cab

• The cab is located on the front frame, and the position of the traction frame, 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), it can be operated standing up, and its volume is 30% larger 
• You can clearly see the steering of the front wheels when bending over to ensure the safety and accuracy of the operation
