Weight: Welcome to inquire
Replacement: Brand Caterpillar

The Cat 460-8745 bolt-on half-arrow cutting edge is an original official wear part made by Caterpillar. It is produced through precise forging technology, following Caterpillar's worldwide strict production rules and quality checking standards.

This cutting blade is tailor-made for the Cat 988K wheel loader. It matches the operational needs of this machine perfectly, including heavy-load digging, frequent material transport and ongoing earthmoving tasks.

The component performs excellently in rough working conditions where wear and collision happen frequently. Common applications are transporting rocks in quarries, excavation for infrastructure building, heavy land levelling in storage yards and stripping hard substances. This product boasts a rational mechanical layout, durable premium metal materials as well as a bolt fixing structure.

It offers all-round protection for the front rim of the loader bucket. It avoids the bucket edge and tooth holders from falling apart, cracking or being worn down ahead of schedule. Moreover, it ensures stable operation of the machine under heavy-duty tasks, lowers your long-term equipment maintenance fees, and effectively safeguards your investment in large construction machinery.

Targeting common operational pain points of large wheel loaders, such as insufficient protection at tooth adapter gaps, rapid local edge wear and high component consumption rates, the Cat 460-8745 features an extended full-coverage protective structure. It accurately fills traditional bucket edge protection blind spots and fully covers the connecting areas of tooth adapters and the core stress zones of bucket base edges. The cutting edge effectively resists continuous scouring, grinding and heavy impact caused by hard rock, ore, gravel and compacted hard soil. It fundamentally eliminates frequent failures including edge thinning, hollowing, cracking and localized over-wear around tooth adapter areas, greatly enhancing overall bucket structural strength and operational stability. It significantly extends the service life of both bucket base edges and tooth adapters, reduces construction interruption and maintenance losses caused by unplanned downtime and frequent part replacement, and ensures continuous, stable and high-efficiency operation for large-scale projects.

Integrally cast from Caterpillar's exclusive DH-2 premium wear-resistant cast steel and processed through multiple precision heat treatment procedures, the material maintains uniform, stable hardness and outstanding structural toughness. It delivers excellent comprehensive performance including superior impact resistance, extreme wear resistance, reliable deformation resistance and strong fatigue resistance. Fully adaptable to harsh working environments of large wheel loaders featuring high-frequency heavy loads, continuous vibration and intense impact, it resists chipping, deformation, dulling and premature abrasion during long-term intensive operation. Its service life far exceeds ordinary aftermarket replacement parts, delivering consistently stable performance and providing reliable quality assurance for large equipment operating under extreme working conditions.

Designed with a classic factory-grade bolt-on modular installation structure, this cutting edge avoids the drawbacks of traditional welded parts such as irreversible installation, cumbersome maintenance and high-temperature deformation. No on-site welding is required, enabling simple installation, fast disassembly and efficient replacement. It greatly shortens maintenance time for large equipment and minimizes downtime losses. The integrated fastening structure provides exceptional stability to withstand continuous vibration and high-intensity impact during heavy-load operation without loosening, offsetting or falling off. Balancing lightweight maintenance advantages and long-term structural reliability, it is perfectly suitable for frequent continuous heavy-duty construction scenarios for large loaders.

Application Scenarios

Specially adapted for genuine buckets of Cat 988K large wheel loaders, it is widely used in high-load, high-wear and high-strength construction scenarios, including large-scale earthwork infrastructure, quarry aggregate handling, high-density material transportation, site leveling and compaction, and heavy-duty yard operations.
