With a standard operating weight of approximately 33,713kg<\/strong>, a 5,500mm moldboard<\/strong> and a powerful C13 engine, the grader delivers dependable cutting, leveling and surface-finishing performance. When equipped with an optional rear ripper, its operating weight can reach approximately 38,500kg<\/strong>.<\/p>\n Each machine undergoes deep refurbishment, complete-system commissioning and load testing before delivery. Powertrain, hydraulic, braking, axle, blade-control and electrical systems are thoroughly inspected to provide stable performance in demanding mining and construction environments.<\/p>\n Each Caterpillar 18 Series Motor Grader<\/strong> 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.<\/p>\n The refurbishment process may include:<\/p>\n This process helps restore reliable operating performance and reduces the risk of early failures after export.<\/p>\n The Caterpillar C13 engine provides strong power and torque for cutting hard surfaces, maintaining mining roads and completing large-scale grading operations.<\/p>\n 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.<\/p>\n Key advantages include:<\/p>\n The exact engine rating, emissions configuration and fuel requirements depend on the selected machine.<\/p>\n The grader is equipped with a 5,500mm-wide moldboard<\/strong> designed for high-productivity road shaping, material spreading and surface finishing.<\/p>\n Blade performance includes:<\/p>\n The moldboard, cutting edges, circle assembly and blade-control components are inspected and adjusted during refurbishment.<\/p>\n 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.<\/p>\n Major advantages include:<\/p>\n The hydraulic and electronic control systems are commissioned and function-tested before delivery.<\/p>\n The grader uses a multiple-speed transmission and heavy-duty axles designed for demanding mining and infrastructure operations.<\/p>\n 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.<\/p>\n Key benefits include:<\/p>\n The standard configuration uses 23.5R25 heavy-duty engineering tires<\/strong>. These tires provide stable support, traction and durability on mining roads, construction sites and unpaved surfaces.<\/p>\n A rear-axle ground clearance of approximately 423mm<\/strong> helps the machine pass over uneven ground and road obstacles.<\/p>\n Tire brand, tread condition and replacement requirements can be confirmed according to the selected machine.<\/p>\n An optional rear ripper can be installed to loosen compacted soil, damaged road surfaces and hard ground before grading.<\/p>\n With the rear ripper installed:<\/p>\n Ripper shank quantity and configuration depend on project requirements and the selected machine.<\/p>\n A front dozer blade can be installed for pushing loose materials, clearing road surfaces and assisting with site preparation.<\/p>\n Combined with the standard moldboard and optional rear ripper, the grader can perform multiple tasks, reducing the need to purchase or mobilize separate machines.<\/p>\n The ROPS cab provides a practical operator environment for extended mining and road-construction operations.<\/p>\n Available cab features may include:<\/p>\n Steering and operating configurations may be adapted where technically feasible and permitted by destination-market requirements.<\/p>\n \u0627\u0644\u0640 Caterpillar 18 Series Motor Grader<\/strong> is suitable for:<\/p>\n Available options depend on the selected machine and technical compatibility.<\/p>\n Before delivery, the grader undergoes functional and load testing covering major operating systems.<\/p>\n Testing may include:<\/p>\n Inspection records, working videos and machine details can be supplied for the selected unit.<\/p>\n Lianning Group supplies used and deeply refurbished Caterpillar motor graders for individual projects, equipment dealers, mining companies and bulk infrastructure procurement.<\/p>\n Multiple machines can be prepared according to consistent refurbishment, attachment and appearance requirements. Export support covers equipment selection, inspection, refurbishment, testing, loading and international shipping coordination.<\/p>\n Looking for reliable Used and Refurbished Caterpillar 18 Series Motor Graders<\/strong> for mining or infrastructure projects?<\/p>\n \u0627\u062a\u0635\u0644 \u0628\u0646\u0627 \u0645\u062c\u0645\u0648\u0639\u0629 \u0644\u064a\u0627\u0646\u0646\u064a\u0646\u063a<\/strong> for available stock, machine year, operating hours, inspection details, working videos, optional attachments and a competitive export quotation.
