DRS Series: The Versatile Performer for Standard Applications
The DRS wheel block series is characterized by its lightweight aluminum alloy housing, maintenance-free bearings, and excellent cost-effectiveness. Its core strength lies in providing reliable performance with minimal lifecycle maintenance.
Typical Applications:
Light to Medium-Duty Overhead Cranes: Used in workshops, warehouses, and distribution centers where smooth travel and low maintenance are prioritized. Ideal for cranes with standard load requirements and operating speeds.
Factory Transfer Trolleys & Assembly Line Systems: Enables precise positioning of trolleys in production environments. The maintenance-free design reduces downtime, while the lightweight construction minimizes energy consumption.
Logistics & Warehousing Equipment: Integrated into stackers, sorting systems, and automated storage/retrieval systems (AS/RS) where reliability and ease of installation are critical.
Light Rail-Guided Vehicles (RGVs): Suitable for systems requiring moderate load capacity and reliable flange-free or guided travel, particularly in clean or noise-sensitive indoor environments.
DRS-M Series: The Heavy-Duty Specialist for Extreme Conditions
The DRS-M series is engineered with a robust spheroidal graphite cast iron (GGG) housing, re-lubricatable tapered roller bearings, and enhanced compensation capabilities. It is built to withstand extreme loads, harsh environments, and demanding operational cycles.
Typical Applications:
Heavy-Duty Gantry & Overhead Cranes: Deployed in steel plants, shipyards, and port container handling areas where high wheel loads (up to 40+ tons per block) and impact resistance are required.
Port Machinery & Shipyard Transport Systems:Used in rubber-tired gantry (RTG) cranes, stacking cranes, and heavy transport vehicles exposed to outdoor weather, saltwater corrosion, and continuous heavy loading.
Mining & Bulk Material Handling Equipment: Applied in stackers, reclaimers, and rotary car dumpers where shock loads, uneven tracks, and abrasive dust necessitate extreme durability and skew compensation.
High-Tonnage Transfer Cars in Metallurgy: Supports ladle transfer cars, coil transport systems, and other high-temperature or heavy-impact applications in metal production facilities.
Large-Scale Automated Industrial Cranes: Ideal for automated process cranes requiring precise long-term alignment, predictable maintenance intervals, and resistance to track misalignment.
Comparison Summary
Conclusion
Whether for routine indoor logistics or extreme heavy-industry applications, the DRS and DRS-M wheel block series offer tailored solutions that optimize performance, reduce lifecycle costs, and enhance operational safety. Selecting the appropriate series depends on specific requirements such as load capacity, environmental conditions, and maintenance strategy.
