Introduction:

The core function of the paver bolts is As high-strength, high-reliability fasteners, they securely join the paver’s various components into a single, integrated unit. Moreover, it maintains structural stability under conditions of high-frequency equipment vibration and heavy-load impacts, thereby ensuring the accuracy and safety of paving operations.

Key features:

Structural connection and fixation to form the complete machine frame.
Bolts serve as the “connecting backbone” for all mechanical components of a paver, from small parts such as the screed base plate and screw distributor blades to larger assemblies like the frame, track undercarriage, and hopper assembly—each relying on specialized bolts for assembly and secure fastening. Without the reliable connection provided by bolts, the equipment cannot form a complete mechanical structure, nor can it safely support operational loads.
Withstand and transmit loads, maintaining structural strength.
During operation, the paver continuously experiences its own weight, the load from the asphalt mixture, as well as impacts and vibrations from the pavement surface. As a critical load-bearing component, the bolts must evenly distribute these loads to the machine frame to prevent localized stress concentrations that could lead to deformation or cracking of the components.
For example, the screed bolts must simultaneously withstand the self-weight of the screed, vibratory compaction impacts, and the reaction forces from the asphalt mixture. If these bolts fail, the screed will directly sink or shift, compromising paving smoothness.
Resist vibration and shock to prevent component loosening and displacement.
During operation, components such as the paver’s vibrator, scraper conveyor, and screw distributor generate high-frequency vibrations, which can easily cause ordinary bolts to loosen. Special high-strength bolts for pavers—used in conjunction with anti-loosening washers or self-locking nuts—effectively resist vibrational impacts, maintain tight clamping over the long term, and prevent component loosening that could lead to abnormal noises, displacement, or even detachment, thereby mitigating the risk of safety accidents.
Ensuring Paving Accuracy and Operational Quality
Components that directly affect paving smoothness, such as screed plates and leveling systems, demand extremely high installation accuracy. Precise bolt tightening ensures that the relative positions of these components remain stable throughout the operation, preventing any displacement caused by vibration, thereby guaranteeing that the pavement’s thickness, slope, and smoothness comply with construction specifications.
Enable disassemblable maintenance of components to reduce O&M costs.
Bolted joints are detachable connections, facilitating equipment inspection, component replacement, and maintenance. When wear-prone parts—such as the ironing plate base and scraper chain—become worn, they can be quickly replaced by removing the bolts, significantly enhancing the equipment’s maintainability and reducing downtime.
