Rim PT08034700 is a critical structural reinforcement accessory exclusively designed for Hydraulic Rock Drills. It excels in harsh mining environments—for instance, open-pit quarry drill rigs, underground tunnel drill wheel assemblies, and coastal mining sites with high humidity.
These settings pose severe challenges for drill rims: heavy load-bearing (≥5 tons), abrasive rock debris impact, salt spray corrosion, intense vibration (up to 30G) from drill movement, and extreme temperature fluctuations. These issues often cause rim deformation, wear-through, rust, or fatigue cracking, leading to drill wheel failure and costly downtime. Yet, Rim PT08034700 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations.
First, its carbon steel Q355 base delivers 1200MPa tensile strength, withstanding heavy drill load-bearing and rock impact without deformation. This extends service life by 150% compared to standard Q235 steel rims. Second, the heat-treated surface (HRC 50-55 hardness) resists abrasion from rock debris and wheel hub friction. Consequently, it reduces wear-related replacement frequency by 30%. Third, the hot-dip galvanized coating (85μm thickness) provides 720-hour salt spray resistance, preventing rust and corrosion in humid or coastal mining environments. Likewise, this ensures long-term structural integrity in corrosive conditions.
Fourth, the reinforced rib design enhances fatigue resistance, withstanding 30G vibration from drill transportation and operation without cracking. Above all, this stabilizes drill wheel assemblies and avoids sudden structural failure during mining tasks. Fifth, the wide temperature adaptability (-40°C~100°C) ensures reliable performance in freezing high-altitude mines and hot underground drill compartments. On top of that, the precision-machined inner diameter (±0.02mm tolerance) ensures a perfect fit with drill wheel hubs, eliminating assembly gaps and reducing vibration noise.
Unlike ordinary industrial rims, this model is engineered for Hydraulic Rock Drills’ load-bearing needs. To elaborate, the Q355 steel targets heavy load resistance, while hot-dip galvanization addresses mining corrosion—features tailored to drill operational demands. Thus, it outperforms generic rims in service life by 160%, significantly reducing maintenance costs.
Our manufacturing team uses precision CNC cutting + heat treatment + hot-dip galvanization technology for the rim. Furthermore, each unit undergoes tensile strength testing (1200MPa) and hardness verification (HRC 50-55). Additionally, the rim undergoes 100,000-cycle vibration fatigue trials to ensure no performance degradation.
Notably, it operates stably in temperatures from -40°C (Arctic mining regions) to 100°C (drill wheel hub systems). Moreover, the galvanized coating passes 720-hour salt spray tests with no rust or peeling. In addition, the heat-treated surface endures 500-hour abrasion trials without excessive wear.
The rim’s bolt-on installation design integrates seamlessly with mainstream Hydraulic Rock Drill wheel/hub assemblies. It requires only standard tools for installation, simplifying maintenance. As a result, maintenance teams can complete replacement in 30 minutes.
Our quality team conducts strict ISO 9001 verification for every unit. We perform tensile strength tests, hardness inspections, corrosion resistance trials and dimensional tolerance verification. Importantly, it complies with ISO 6336 international mechanical structural steel standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces rim-related failure rates by 93%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 55%.
It not only reinforces drill wheel structural stability but also extends the service life of drill wheel/hub assemblies by 85%. Overall, Rim PT08034700 delivers cost-effective, high-strength performance for long-term mining operations. Beyond that, it minimizes downtime caused by rim failure, maximizing operational efficiency and project profitability.
