Deep Refurbishment Process

Each Caterpillar 18 Series Motor Grader undergoes a systematic inspection and deep refurbishment process. Major structures and operating systems are inspected, repaired, adjusted or replaced according to the actual condition of the selected machine.

The refurbishment process may include:

• Complete-machine dismantling and inspection
• Engine and cooling-system inspection
• Transmission and drivetrain inspection
• Heavy-duty axle inspection
• Wet braking-system inspection
• Steering-system testing
• Hydraulic-pump and valve inspection
• Hydraulic cylinder and pipeline maintenance
• Moldboard, circle and drawbar inspection
• Blade-control system calibration
• Articulation-joint inspection
• Electrical and control-system testing
• Cab interior refurbishment
• ROPS structure inspection
• Tire and wheel inspection
• Exterior repair and repainting
• Complete-machine commissioning
• Driving and functional testing
• Load testing before delivery
• Final factory quality inspection

This process helps restore reliable operating performance and reduces the risk of early failures after export.

Caterpillar C13 Heavy-Duty Engine

The Caterpillar C13 engine provides strong power and torque for cutting hard surfaces, maintaining mining roads and completing large-scale grading operations.

Its mature design supports convenient servicing and access to replacement parts in many international markets. Direct-injection configurations can provide practical adaptability for overseas projects where fuel conditions and maintenance resources vary.

Key advantages include:

• Strong power for heavy grading operations
• High torque under demanding loads
• Stable performance during long working cycles
• Mature mechanical and electronic systems
• Broad global parts availability
• Convenient servicing and maintenance
• Suitable for mining and infrastructure projects

The exact engine rating, emissions configuration and fuel requirements depend on the selected machine.

5.5-Meter Heavy-Duty Moldboard

The grader is equipped with a 5,500mm-wide moldboard designed for high-productivity road shaping, material spreading and surface finishing.

Blade performance includes:

• 5,500mm standard blade width
• Maximum lifting height of approximately 400mm
• Maximum cutting depth of approximately 470mm
• Blade-angle adjustment up to approximately 65°
• Left and right lateral side shift
• Precise hydraulic positioning
• Suitable for cutting, spreading and leveling materials

The moldboard, cutting edges, circle assembly and blade-control components are inspected and adjusted during refurbishment.

Precise Electro-Hydraulic Control

The electro-hydraulic control system provides responsive and accurate moldboard movement. This allows the operator to make precise blade adjustments during road leveling, slope shaping and drainage construction.

Major advantages include:

• Accurate blade positioning
• Smooth hydraulic response
• Improved grading precision
• Consistent road-surface finish
• Reduced repeated passes
• Better productivity on large projects
• Flexible operation for slopes and road shoulders

The hydraulic and electronic control systems are commissioned and function-tested before delivery.

Heavy-Duty Drivetrain and Axles

The grader uses a multiple-speed transmission and heavy-duty axles designed for demanding mining and infrastructure operations.

Wet braking components provide reliable braking performance in intensive working conditions. The reinforced drivetrain and axle system are suitable for extended operation on rough, uneven and heavily loaded mining roads.

Key benefits include:

• Multiple working and travelling speeds
• Strong low-speed control
• Heavy-duty axle construction
• Reliable wet braking system
• Good durability on mining roads
• Stable operation during cutting and ripping
• Reduced brake exposure to dust and debris

23.5R25 Heavy-Duty Tires

The standard configuration uses 23.5R25 heavy-duty engineering tires. These tires provide stable support, traction and durability on mining roads, construction sites and unpaved surfaces.

A rear-axle ground clearance of approximately 423mm helps the machine pass over uneven ground and road obstacles.

Tire brand, tread condition and replacement requirements can be confirmed according to the selected machine.

Optional Rear Ripper

An optional rear ripper can be installed to loosen compacted soil, damaged road surfaces and hard ground before grading.

With the rear ripper installed:

• Overall machine weight can reach approximately 38,500kg
• Total machine length increases to approximately 12,051mm
• Hard ground can be loosened before leveling
• Road-maintenance efficiency can be improved
• The machine can complete more operations without additional equipment

Ripper shank quantity and configuration depend on project requirements and the selected machine.

Optional Front Dozer Blade

A front dozer blade can be installed for pushing loose materials, clearing road surfaces and assisting with site preparation.

Combined with the standard moldboard and optional rear ripper, the grader can perform multiple tasks, reducing the need to purchase or mobilize separate machines.

Comfortable ROPS Cab

The ROPS cab provides a practical operator environment for extended mining and road-construction operations.

Available cab features may include:

• ROPS protective structure
• Adjustable operator seat
• Wide working visibility
• Air conditioning
• Clear instrument display
• Ergonomic operating controls
• Work lights
• Refurbished interior panels
• Optional monitoring equipment

Steering and operating configurations may be adapted where technically feasible and permitted by destination-market requirements.
