Wheel Block System

The Demag DRS 125 travel wheel block is a high-performance, modular wheel system engineered specifically for heavy-duty cranes, hoists, transfer carts, and industrial automation equipment. This system features a compact, rugged housing and diverse configuration options, allowing the DRS 125 to excel under complex and demanding operational conditions. Below is a detailed engineering breakdown of its key features, material specifications, and versatile connection methods.

Advanced Wheel Housing Design & Materials

High-Strength Housing: We construct the rugged, compact housing from high-strength spheroidal graphite cast iron to ensure maximum structural integrity and reliable performance under high static and dynamic loads.

Precision Machining: Five-sided machined surfaces provide precise alignment, exceptional rigidity, and perfectly square connection interfaces for seamless assembly.

Structural Integrity: Our optimized internal reinforcement ribs effectively minimize stress concentration points, preventing structural fatigue in harsh or vibrating environments.

Modular Efficiency: The compact envelope of the housing simplifies initial installation, retrofitting, and routine maintenance.

Diverse Wheel Types and Metallurgical Excellence

To accommodate various track environments and operational requirements, our DRS 125 product line offers multiple wheel configurations:

Double-Flanged Wheels: Engineered for overhead steel rails and traditional crane runways, these wheels ensure reliable tracking and prevent derailment.

Flangeless Wheels: These flat wheels provide an ideal solution for smooth, guided operations on flat steel tracks.

Polyurethane-Coated Wheels: This series features a high-performance polyurethane elastomer tread that delivers quiet operations, excellent floor protection, and high hydrolysis resistance in AGV or warehousing systems.

Metallurgy & Hardening: Our production team subjects all steel wheels to precise heat treatment, which delivers superior wear resistance and significantly extends service life.

Four Flexible Connection Methods

The versatile housing design of the DRS 125 supports four standard mounting interfaces, allowing the unit to integrate seamlessly with your superstructure:

Top Connection: Users can bolt the block directly to the upper structure via the top machined surface for a straightforward, high-rigidity installation.

Pin Connection: The wheel block connects via a central pin or torque arm, providing pivot flexibility to accommodate minor structural misalignments.

Side Connection: The system mounts via side-machined surfaces, making it ideal for low-clearance spaces or specific compact side-load setups.

End Connection: Installers can fix the block via an end mounting plate to suit specific cantilevered or longitudinal assembly layouts.

Technical Specifications of DRS 125 Wheel Block

High-Precision Transmission & Premium Bearing System

Involute Splined Shaft: The travel wheel is driven via an internal splined connection. This design ensures backlash-free torque transmission, precise axial alignment, and high shock-load resistance.

Heavy-Duty Sealed Bearings: The inner assembly is equipped with premium, life-lubricated ball bearings that are completely sealed against dust, moisture, and industrial debris.

Temperature Range: Because we pre-pack the bearings with specialized high-temperature grease, the assembly guarantees smooth operation across a wide thermal envelope from -180°C to 120°C, significantly reducing your maintenance overhead.
