DRS Wheel Block System
High Duty Demag DRS 400 Wheel Block With Single Flange
High rigidity Demag DRS 400 wheel block with single flange is used to support cranes and load devices that can bear a load of 30 t.
The High-Rigidity DRS 400 wheel block with a single flange is a premium solution engineered to support cranes and heavy-duty load devices. Designed for seamless integration, these wheel sets are the cornerstone of modern travel mechanisms for cranes, stackers, palletizers, and RGV trolleys.
Key Features of DRS 400 Wheel Blocks
Robust Structural Integrity: Manufactured from high-grade ductile iron (GGG 70) or high-rigidity metal forgings. The tight housing geometry protects internal bearings from debris, dust, and side collisions while distributing heavy loads efficiently.1
Versatile Wheel Materials: Available in stainless steel, polyurethane (PU) coating, or ductile iron. These materials ensure smooth operation, high traction, and precise braking even under maximum load.
Customizable Configurations: Beyond standard single-rim designs, we offer double-rim, no-rim (flangeless), and bespoke wheel profiles to fit specific rail types.
Extreme Environment Resistance: Engineered for high-temperature applications up to 482°F (250°C). The DRS series, including the DRS 315. excels in hot, humid, and corrosive industrial environments.
High Load Capacity: A single DRS 400 wheel set (weighing 201kg) supports up to 30 tons. Multiple mounting options are available: sideways, top, end, or pin-mounted.
Technical Specifications & Modular Design
As a critical component of European-style crane travel mechanisms, the Demag-compatible DRS 400 is considered a high-end industry standard. It consists of high-precision wheels, shafts, bearings, and a fully machined bearing box.
Modular Drive Integration
The housing is fully machined on all sides, allowing it to be connected to almost any customer-specific design. It is fully compatible with the Demag modular system, including offset and angular gear reduction motors for both single and central drive configurations.2
