Road construction machinery plays a crucial role in the process of road construction. This document presents detailed information regarding the various types of machinery used, their specifications, operation records, and maintenance details during the construction process.
The pavers used in the project with a maximum paving width and a paving thickness range. It is equipped with an advanced material feeding system that can ensure a consistent flow of asphalt or concrete.
The engine power of the paver, providing sufficient power to drive the conveyor belts, screed, and other moving parts during the paving operation.
Daily operation hours of the pavers are recorded.
The temperature of the paving material during operation is also monitored.
There are different types of rollers employed.
The vibratory roller is equipped with an adjustable vibration frequency. Its compaction force can be adjusted according to the thickness and type of the road layer.
Operation logs show that the rollers were used in multiple passes over the paved surface.
The excavators used in the road construction project. The hydraulic system of the excavator provides powerful and precise control of the boom, arm, and bucket movements.
The engine of the excavator has a power rating, enabling it to handle various types of soil and rock materials during the excavation of road cuts and drainage ditches.
The bucket geometry is designed to efficiently scoop and transport materials such as gravel, sand, and crushed stone. The lifting height of the loader's boom allows it to load materials onto trucks or stockpiles.
The loader features a hydrostatic transmission system for smooth and efficient operation.
Operation data reveals that the loaders were mainly used for loading materials onto transport vehicles. The distance traveled during loading operations within the construction site was recorded.
Before starting the operation each day, a series of checks are conducted on all machinery. This includes checking the fluid levels (engine oil, hydraulic oil, coolant, etc.), tire pressure (for wheeled machinery), and the condition of belts and hoses.
The operation of lights, horns, and other safety devices was verified. In the case of rollers, the brakes were tested to ensure their proper function before starting the compaction work.
Weekly maintenance tasks involve more in - depth inspections. The air filters of all machinery were cleaned or replaced if necessary. The fuel filters were checked for clogging, and the fuel lines were inspected for leaks.
On a monthly basis, more comprehensive inspections were carried out. The engine of each machinery was serviced, including changing the oil and oil filter. The spark plugs (for gasoline - powered engines) or fuel injectors (for diesel - powered engines) were inspected and cleaned or replaced if required.
Every quarter, the mechanical components such as the gears, bearings, and shafts of the machinery were inspected for wear. The undercarriage of crawler - type machinery (if applicable) was checked for track tension and wear of track shoes. Any damaged or worn - out parts were replaced to prevent further damage to the machinery.
During the annual maintenance, major overhauls were performed. The engines were disassembled (if necessary) for a detailed inspection of internal components. The transmission systems, including the gearboxes and differentials, were serviced. The structural integrity of the machinery was assessed through non - destructive testing methods such as ultrasonic testing for welded joints.
The electrical systems of the machinery were also thoroughly inspected. The wiring harnesses were checked for insulation damage, and the control panels and sensors were calibrated to ensure accurate operation. New paint was applied to protect the machinery from corrosion if needed.
