Dynapac asphalt paver conveyor chains are specifically designed for heavy-duty applications associated with road construction machinery like paver laying equipment. These chains' resilience and reliability make them a preferred choice in the asphalt paving industry. The following are common types:
This chain type has holes (or pins) that allow the attachment of crossbars, slats, or other accessories to convey materials. It's often used in asphalt pavers to transport hot mix asphalt from the hopper to the distribution augers. Because of the hollow structure, these pins give more flexibility for configurations.
These chains are strengthened and aimed at industries with larger loads and more aggressive use. They bear higher tensile and fatigue strength, as well as resist abrasion and elongation. In asphalt applications, the heavy-duty chain ensures reliable operation even in adverse and harsh weather conditions.
These chains are similar to roller chains; however, they have every second link extended (one extra link) to permit the chain to run on wider sprockets. This type of chain finds utility in lower-power-distance transmission applications.
Chains are called 'drop forged' conveyor chains which have links produced by the drop forging process of steel. Such chains are great for high-load applications. The paver conveyor chains are ideal for sustaining heavy paver loads, including the aggregates and asphalt mixtures used in road construction.
These chains are specially constructed using heat-treated materials and different heat-resistant coatings to ensure they are ideal for use in extreme environments. Asphalt consists of large quantities of extremely hot mixtures. Therefore, heat-resistant chains ensure longevity and reliability in such an environment.
This is the primary use industry for a dynapac asphalt paver conveyor chain. It helps convey hot mix asphalt from the hopper to the distribution augers amid the laying process. Dynapac asphalt chains ensure smooth material flow with greater strength for challenging and aggressive working conditions.
As chains transport aggregate and asphalt cement during production in asphalt mixing plants, they withstand abrasion and high temperatures. Conveyor chains are vital in ensuring accurate materials transport, and dynapac chains are valued for their effective durability and dependability.
Chains for conveying materials such as coal, minerals, and other aggregates are needed in this operation. Forged conveyor chains are robust and can sustain heavy loads. Hence, they are used in this particular industry. Material handling systems apply conveyor chains in the transport of bulk materials.
Broadly, conveyor chains are used in many other industries to convey and transport various materials, such as inbulk material handling systems. These systems employ chains to move bulk materials such as coal, minerals, and heavy raw materials employed in manufacturing processes. The durability of dynapac asphalt chains makes them useful in several manufacturing environments.
Chains convey sand, metal, and cast products in foundries. Forged conveyor chains endure high abrasions and thermal fluctuations that are common in foundry settings. Hence, they prove instrumental in enhancing productivity through efficiency in material handling.
These paver chains handle slag, steel ingots, and other heavy materials in steel mills. They operate under extremely harsh and abrasive conditions and, therefore, require robust chains as conveyor chains. Dynapac asphalt chains for high tensile strength and longevity traits are especially useful in the steel mill industry.
Material transportation, such as metals, plastics, and paper, also requires conveyor chains in the recycling industry. These materials can be light or heavy, depending on what is required, but the chains should be able to handle the stress and strain brought about by varying weights. The strength and versatility of dynapac asphalt paver chains make them suitable for this purpose.
Chains convey solid waste materials in landfills and waste-to-energy plants. They resist irregular waste shapes and sizes and avoid potential clogging. Conveyor chains that withstand the rigorous demands of the waste and landfill environments are critical for reliable operation in waste management facilities.
Durability
Dynapac asphalt conveyor chains are primarily constructed from premium steel, giving them adequate strength and, therefore, durability. In addition, they resist abrasion and may, therefore, be satisfactorily utilized in harsh and aggressive environments.
Semi-Nodular Design
The semi-nodular design of a chain stresses material flow and minimizes friction. This means smoother operation with less power consumption besides a longer chain and equipment life.
Precision Engineering
Hence, the sprockets and drive parts mesh perfectly, enabling precise material handling. This precision is vital in paving applications to aid consistent asphalt flow for enhanced surface quality.
Heat Resistance
Dynapac asphalt paver conveyor chains feature additional heat treatment for applications involving hot paving mixtures. In other words, advance-resistant treatment makes them handle temperature extremes without stretching or deforming.
Easy Maintenance
Chain maintenance is a critical consideration in the design of the dynapac chain. The ease of lubrication, along with the replacement of links and other parts, reduces downtime in paving operations, bringing cost savings and productivity.
Customization Options
Dynapac chains provide a variety of specifications, such as pitch sizes and material choices. Such flexibility offers asphalt pavers the opportunity to best choose the chain suited for their application, guaranteeing optimum operation.
The process of installation can be challenging, however, with steps that ensure appropriate installation. Here are a few steps to consider:
Drain the existing conveyor system
The paver hose should be drained of any asphalt and any remaining residue. It helps prevent clogging and ensures the new chain moves smoothly.
Remove the conveyor system's covers and components
Loosen the bolts holding the covers and relevant components using the required tools. Chapman screwdriver and his other tools can be used to get the work done. A socket set can also allow faster work as well.
Detach the old chain from the conveyor system
Lock the rotating parts of the conveyor system wheel. The old chain is then detached after loosening the relevant chain rivets and sprocket bolts. Only detach one end; this means the old chain can be used to guide the new one in.
Install the new chain
As the name suggests, the new chain should be installed in the conveyor system. The conveyor system should be in a loop by threading the new chain through the conveyor system, as the old chain was through the conveyor system.The new chain through the path used by the old chain, the old chain through the path used by the old chain.
Reconnect the chain
Use the rivets to reconnect the two ends of the chain. Ensure the rivets are well seated and easy to rotate; this way, the conveyor runs smoothly.
Reinstall the covers and components
Take back all the parts removed during installation, including the conveyor covers. Remember to grease all moving parts before reinstalling the conveyor covers.
Lubrication
Conveyor chains demand extensive lubrication with ease of access by the owner/installer. It minimizes friction, thus careening elongation and wear. Dynapac suggests premium grease be applied in the inside rollers of every link for the best operation.
Regular Inspections
For maintenance, users should conduct visual and physical inspections of the chain for signs of wear, elongation, and damage/physical degradation. Frequent checks help catch problems early, preventing further damage and the resultant costly downtime.
Tension and Alignment Monitoring
The recommended working tension of a chain should be monitored to ensure efficient working. An overtightened or undertightened chain can cause uneven wear and appropriation of the equipment. Similarly, proper alignment of chain-to-sprocket interaction is vital for efficient energy transfer and material handling.
Cleaning
The buildup of asphalt debris, dirt, and other foreign materials on the chain surface and inside its links can contribute to abrasion and corrosion. Cleaning using brushes and safe solvents help to remove the build-up, enhancing chain life.
Wear Measurement
Use calipers to measure the chain length. When the chain has stretched a certain length (usually indicated by wear marks on the rollers), it is time to replace it. Running a worn-out chain can damage sprockets and decrease overall efficiency.
Material Selection
Premium-quality materials are pivotal and important to the longevity of asphalt paver chains. High-strength steel alloys provide supreme tensile strength and heat resistance to handle the loads and asphalt paving stresses.
Heat Treatment
Heat treatment enhances the wear and fatigue resistance of the chain links and rollers by further hardening the steel. Chains used in asphalt applications demand adequate heat treatments to stay true to their resistance to elongation and ultimate strength performance.
Link Design and Manufacture
Manufacturers make link designs to guarantee adequate load dispersion across the chain. Further, manufacturers use advanced technology, such as laser cutting, for precision to enhance link strength and enhance smoother operation.
Roller Coating
The roller surface demands adequate coating so the chain is protected from abrasion. These assure additional protective layers over the rollers, enabling better wear resistance.
Quality Control Tests
Quality control is very important for product functionality backup. These include tensile tests, fatigue tests, and heat resistance checks of the dynapac asphalt paver conveyor chains to ensure they meet required standards.
Proper Chain Guards
Proper chain guards prevent accidental contact with rotating components, thereby preventing injuries. Further, guards reduce the probability of chain snap and resultant flying debris, posing a danger to on-site workers.
Adequate PPE
Proper personal protective equipment must be worn when operating paving machinery. Hard hats, gloves, and steel-toed boots protect the worker from injury in possible events like slips, chains snapping, and equipment accidents.
Noise Levels Monitoring
Heavy equipment use within an asphalt paver produces significant noise, which may cause potential long-term harm to a worker's hearing. Employing ear protection goes a long way toward preventing hearing loss.
Emergency Stop System
Conveyor systems specifically feature emergency stop systems that enable the stopping of all operations and activities when disaster and dangers happen. Workers must know their locations and functionality when emergencies arise and need instant stopping power.
Regular Safety Inspections
Hazards such as loose chains, wear, and faulty conveyor parts can expose workers to such dangers. Conduct chain and conveyor safety inspections to mitigate such risks, so any found is fixed before they cause accidents.
