Performance Characteristics:
Construction machinery gearboxes, crucial for Power transmission in various applications, must withstand diverse demanding operating conditions, thus exhibiting a series of unique performance characteristics. First is high load capacity, enabling them to handle immense torque and ensure stable operation during heavy - duty tasks such as excavation, lifting, and loading, driving machinery to efficiently complete assignments. Second, they offer exceptional reliability through premium materials and advanced manufacturing processes, featuring robust structural designs for sustained long - term operation. This minimizes failures and reduces work interruptions caused by maintenance. Additionally, they demonstrate excellent adaptability, functioning reliably in harsh environments including high/low temperatures, dust, and humidity. To meet diverse operational demands, gearboxes offer a wide, precisely adjustable gear ratio range, enabling flexible adaptation to various working conditions. Furthermore, their outstanding shock resistance effectively absorbs impact forces during operation, safeguarding transmission system stability and enhancing overall machinery performance and reliability.
Main technical parameters:
Construction machinery gearbox transmission ratio range: 1.2 - 100, accommodating speed control requirements for excavators, cranes, and other equipment involved in road construction , piling machinery , and more. Transmission efficiency ≥96% to reduce energy consumption. Rated torque coverage: 50 - 5000 N·m, with instantaneous overload capacity reaching 1.5 - 2 times. Gears are forged from high - strength alloy steel with carburized and quenched tooth surfaces achieving HRC58 - 62 hardness. Center distance specifications range from 80 - 600mm to accommodate diverse machine installation dimensions relevant to different applications like road construction and piling machinery. Sealing employs a dual - lip oil seal + labyrinth composite design to prevent dust and mud ingress. Temperature resistance spans - 30°C to 120°C for multi - environment operation. Equipped with a forced lubrication system compatible with medium - duty industrial gear oils like L - CK C220, it delivers over 10,000 hours of service life under standard conditions. High - torque models feature bearings with a rated dynamic load capacity ≥50kN, ensuring stable heavy - duty operation in various construction scenarios including those related to road construction and piling machinery.
Main application areas:
Construction machinery gearboxes find extensive use across multiple sectors. In building construction, tower cranes rely on gearboxes for vertical lifting of heavy loads, while concrete mixer trucks depend on them to transmit power for mixing and transportation. In mining operations, excavators utilize gearboxes to perform digging and rotation, and loaders leverage them for efficient material scooping and handling. During road construction, road rollers utilize gearboxes to drive compaction rollers, while motor graders employ them for leveling operations. Piling machinery also depends on construction machinery gearboxes for Power transmission to drive the piling process. In agriculture, combine harvesters depend on gearboxes to coordinate component operations for grain harvesting and threshing. Construction machinery gearboxes serve as the core power transmission hub for numerous mechanical devices, enabling efficient operation across industries.
Important Tips:
When using construction machinery gearboxes, especially those for road construction and piling machinery, strictly adhere to the following guidelines. Before operation, thoroughly review the user manual and strictly follow standard procedures for startup, operation, and shutdown to prevent equipment damage from improper handling. During operation, closely monitor oil temperature, oil pressure, and operational sounds. Immediately shut down and investigate if oil temperature becomes excessively high, oil pressure shows abnormalities, or unusual noises occur. Regularly inspect lubricant levels and quality, changing oil at specified intervals to ensure proper lubrication and minimize component wear. Maintain gearbox cleanliness to prevent dust and debris ingress. Additionally, select gearboxes appropriately for operating conditions, avoid prolonged overload operation, and perform comprehensive maintenance and inspections periodically. Promptly identify and address potential issues to extend service life and ensure safe, efficient operation in all applications including road construction and piling machinery.
