The Demag DRS 125 travel wheel block is a high-performance modular wheel system for heavy-duty cranes, hoists, and other industrial equipment. The wheel housing is compact and rugged, meeting the needs of a wide range of complex working conditions. The main features are described in detail below.

DRS 125 wheel housing design

The compact and rugged wheel housing of the DRS 125 is made of high-strength ductile iron (GGG 70), ensuring its reliability and durability under heavy load conditions. The housing is precision machined to provide high rigidity and precise connection surfaces, ensuring system stability and accuracy. Its modular design simplifies installation and maintenance, while internal reinforcement ribs enhance structural integrity under dynamic loads. The optimized geometry reduces stress concentration points, ensuring long-term durability in harsh environments.

Type and material of Demag wheel block DRS 125

The wheels of the DRS 125 are available in a variety of materials and wheel types, including guide wheels with double-sided flanges, flat wheels without flanges, and flangeless wheels with polyurethane coating. These options enable it to adapt to different tracks and operating conditions, prevent derailment, and provide a high degree of flexibility. The wheels are precision heat treated (case hardened to 55-60 HRC) to resist wear and deformation.

Demag ranges connection methods

DRS 125 offers four standard connection methods to facilitate integration with the customer's superstructure:

• End connection: Connected to the structure through the end mounting plate, suitable for specific installation requirements.

• Top connection: Directly connected to the superstructure through the top mounting surface, providing a simple and direct installation method.

• Side connection: Connected through the side mounting plate, suitable for occasions with limited space or specific design requirements.

• Pin connection: Connected through the pin shaft, providing flexible installation options to adapt to different design requirements.

Load capacity and deadweight of DRS 125 wheel system

The maximum load capacity of the DRS 125 wheel block is 5 tons and its own weight is 9.9 kg. Achieves an excellent strength-to-weight ratio. This lightweight design reduces inertial forces during acceleration/deceleration, thus improving energy efficiency. The efficient load capacity makes it suitable for heavy-duty applications that require high reliability and durability.

Splined shaft of DRS 125 travel wheel

The DRS 125 is equipped with a splined shaft design, which ensures precise torque transmission and axial alignment. This design improves the overall performance and service life of the system.

Sealed ball bearings of Demag DRS 125 wheel block system

The wheel housing is built with high-quality sealed ball bearings that are dust-proof, moisture-proof and debris-proof. These bearings are pre-lubricated with high-temperature grease and can run smoothly for a long time in a temperature range of -20°C to 120°C, maintaining excellent performance and reducing maintenance costs.

This variety of wheel designs enables the DRS 125 to meet the needs of various tracks and operating conditions.

The Demag wheel set is an ideal choice for industrial lifting and handling equipment with its sturdy box design, diverse connection methods, and efficient operating performance. It's a modular design and multiple configuration options ensure flexibility and reliability in various applications.
