Boom Rear Cylinder(Left) PT01070500 is a core hydraulic actuation component for Hydraulic Rock Drills. It is engineered for heavy-duty mining left boom pitch control and structural load support. For instance, it drives left boom elevation in underground tunnel drilling rigs. Additionally, it adjusts drill head positioning in open-pit hard rock blasting operations.
Mining environments pose severe challenges for drill boom cylinders. First, high hydraulic pressure risks tube deformation and oil leakage. Second, 40G continuous vibration damages piston rod seals and reduces thrust stability. Third, rock dust and slurry abrade rod surfaces and cause seal failure. Fourth, mining humidity triggers cylinder body corrosion and coating peeling. Fifth, extreme temperature swings affect seal elasticity and stroke precision.
These issues often lead to cylinder malfunction. For example, a worn piston rod causes boom drift and drill head misalignment. As a result, costly downtime and drilling efficiency loss occur. Yet, Boom Rear Cylinder(Left) PT01070500 solves these pain points with robust design.
First, its high-strength 27SiMn seamless steel tube delivers exceptional pressure resistance. Moreover, it withstands 35MPa working pressure without deformation. This outperforms standard steel tubes by 120% in pressure capacity. Consequently, thrust stability improves significantly.
Second, the 45# alloy steel piston rod with hard chrome plating achieves high wear resistance. Notably, it provides 5000-hour wear protection against rock dust and slurry. This prevents surface scratching and seal damage. As a result, service life extends by 250% vs. standard cylinders.
Third, the anti-corrosion epoxy powder coating + primer offers 1000-hour salt spray resistance. This outperforms uncoated cylinders by 70% in harsh environments. Furthermore, it repels mining slurry and rust formation. This avoids structural corrosion and coating delamination.
Fourth, the fluororubber seal and vibration-dampened mounting design absorb 40G vibration. Importantly, it maintains seal integrity and ±0.5mm stroke precision under extreme drill operation. This eliminates oil leakage and boom drift risks. This enhances overall boom control reliability.
Fifth, the boom rear cylinder tolerates extreme temperatures (-40°C~120°C). On top of that, it retains seal elasticity and thrust performance in all conditions. This eliminates seal hardening or leakage risks in freezing or hot mines.
Unlike generic industrial hydraulic cylinders, this model is purpose-built for drills. Specifically, the left-side dedicated design targets symmetric boom actuation demands. Additionally, the high-thrust output addresses heavy boom load support needs. These features align with real mining demands. As a result, it outperforms standard cylinders by 220% in service life. This cuts replacement costs and unplanned downtime.
Our manufacturing process uses precision honing and hard chrome plating. Furthermore, it involves pressure testing and stroke precision verification. Each unit undergoes 35MPa pressure trials and ±0.5mm stroke checks. Notably, no performance degradation is allowed before shipment.
The cylinder operates reliably in all extreme mining conditions. Moreover, the seamless steel tube endures 10,000-cycle pressure tests. No deformation or cracking occurs during this period. Additionally, the hard chrome plating remains intact for 30+ months.
The flange-mounted design integrates seamlessly with drill left boom assemblies. It requires only standard hydraulic tools for fitting. Consequently, maintenance teams complete replacement in 30 minutes. This minimizes operational downtime.
Our quality team conducts strict ISO 9001 verification for every unit. For example, tests include pressure resistance checks, wear resistance trials and corrosion tests. Stroke precision is also verified. Importantly, it complies with ISO 4414 hydraulic standards and mining safety regulations.
It ensures precise left boom pitch control and load support of drill systems. Additionally, it extends the service life of mating boom structures and drill heads by 90%. Overall, it delivers cost-effective, industrial-grade reliability. It minimizes downtime from boom cylinder failure. As a result, this maximizes operational efficiency and project profitability.
