Conveying System

In smart warehousing and automated logistics systems, transverse conveyors (such as RGVs, shuttles, and track transfer cars) serve as the core links connecting various storage aisles with inbound and outbound conveyor lines. Because they require high-frequency, heavy-duty 90° perpendicular docking, they place extremely high demands on the travel system's load capacity, running smoothness, positioning accuracy, and maintenance convenience.

To address these stringent and multi-dimensional challenges, introducing a high-quality, modular wheel block system has become the key to breaking through performance bottlenecks. As an industry-recognized solution for heavy-duty mobility, the Demag DRS Wheel Block System—with its exceptional industrial design—perfectly aligns with the evolutionary needs of transverse conveyors.

The Advantages of DRS Wheel Blocks on Transverse Conveyors

Traditional industrial wheels often adopt a loose-part assembly mode consisting of wheel and independent bearing housing and exposed transmission gear, which suffers from pain points such as low installation accuracy, a tendency to crabbing (deviating), and difficult maintenance. The DRS wheel block completely integrates these components, bringing a qualitative leap to transverse conveyors:

1. Modularity: The DRS wheel block is a highly integrated, enclosed housing that contains high-performance wheels, precision bearings, and seals. After the steel chassis of the transverse conveyor is welded, there is no need for extremely complex machining to align bearing holes. The DRS wheel blocks can be bolted directly to the vehicle frame, greatly simplifying the manufacturing and assembly process of the entire vehicle.

2. Perfect Power Matching: To prevent the vehicle body from crabbing, Drive Unitis typically utilized in transverse conveyors. The design of the DRS wheel block perfectly meets this requirement:

①Its gearbox connection features a spline shaft design.

②The central drive shaft can be inserted directly into the wheel block to drive the wheel without the need for additional couplings, resulting in minimal transmission backlash and extremely fast start-stop response.

3. Multiple Materials and Profiles to Adapt Precisely to Rail Environments

Transverse conveyors usually run on standard square steel rails or crane rails. The DRS wheel block system offers an exceptionally rich selection of wheel profiles and materials:

①Special Profiles with Single/Double Flanges: These precisely match different rail geometries, providing excellent lateral guiding capabilities.

②High-Strength Cast Steel Wheels: Cast from high-quality, high-strength alloy steel and precision machined, these wheels possess exceptional mechanical strength and outstanding impact toughness. Optimised via microstructure control and surface hardening treatments, they exhibit superior wear resistance and fatigue life. Even under harsh working conditions characterized by frequent start-stops, heavy-duty reciprocating movements, and strong lateral force impacts, they ensure long-term stability at the wheel-rail interface, delivering high running accuracy and mechanical reliability.

③High-Performance Polyurethane Travel Wheels:These are suitable for trackless or light-rail transfer scenarios that require low noise, high quietness, lightweight design, or floor protection.

Key Technical Parameters

Leveraging the engineering benefits of modular design, we offer the complete high-precision DRS wheel block system ranging from DRS112 to DRS500.

Typical Industry Application Scenarios

1. Automotive Stamping and Assembly Lines: DRS wheel blocks are used on transverse rail guided vehicles (RGVs) to smoothly transport dies or automotive bodies-in-white weighing over ten tons, ensuring high-speed, seamless docking between workstations.

2. Cold Chain and Dense Warehousing: In low-temperature environments, the highly sealed DRS wheel blocks effectively prevent the ingress of moisture and frost, guaranteeing that the transverse transfer system operates without freezing or seizing.

3. Heavy Machinery and Metallurgical Industries: In steel mills or heavy machining workshops, cross-bay track transfer cars utilize large-size DRS wheel blocks (such as DRS 250, DRS 315, or larger) to withstand extreme loads and harsh, dusty environments.

Summary

The transverse conveyor is a tough piece of "hardcore" equipment in industrial automated logistics, and the DRS wheel block system has successfully conquered this challenge by virtue of its excellent modular integrated design, robust mechanical rigidity, and perfect drive compatibility. It not only significantly lowers the design and manufacturing thresholds for equipment OEMs but also provides end-users with long-life, maintenance-free, and high-precision smart operation guarantees.
