DRS Wheel Block System with Spheroidal-Graphite Cast Iron (GGG 70)

In modern industrial handling and automated conveying systems, the DRS wheel system is widely used in cranes, stackers, automated warehouses and other equipment due to its compact structure, stable performance and flexible installation. The DRS wheel system made of ductile iron (GGG 70) has achieved further improvements in strength, toughness and durability, making it an ideal choice for heavy-duty applications.

1. Characteristics of spheroidal-graphite cast iron GGG 70

GGG 70 is a high-strength spheroidal-graphite cast iron material with the following significant characteristics:

High tensile strength: The minimum tensile strength reaches 700 MPa, which is much higher than ordinary gray cast iron and can withstand greater mechanical loads;

Good ductility and toughness: The spheroidal graphite structure effectively improves impact resistance and avoids brittle fracture.

Excellent wear resistance: Suitable for high-frequency operation and harsh working conditions, extending the service life of the wheel set.

Good processing performance: Convenient for precision processing and subsequent heat treatment to ensure structural accuracy;

Stable size and structure: Maintain good geometric stability during heavy-duty operation.

2. Advantages of DRS wheels using spheroidal-graphite cast iron

Stronger load-bearing capacity: GGG 70 material enables the wheels to handle loads of up to several tons or even more than ten tons, suitable for heavy-duty logistics handling systems;

Longer life: Under high-intensity and high-frequency use conditions, ductile iron is more durable than ordinary steel or gray cast iron wheels;

Better impact resistance: It can effectively resist the impact and vibration caused by the track or equipment operation;

High reliability and low maintenance cost: The wear and fatigue resistance makes the equipment maintenance cycle longer and the operating cost lower;

Adapt to complex working conditions: It can operate stably in harsh environments such as high temperature, low temperature or humidity.

3. Application scenarios

DRS wheels made of GGG 70 are widely used in the following fields:

Bridge cranes and gantry cranes: high-strength wheels can withstand frequent lifting and landing and lateral operation loads;

Stacker and conveyor trolley system: provide stable and reliable rail operation support;

Automated three-dimensional storage system: ensure the efficiency and safety of high-density cargo handling;

Port and heavy equipment: adapt to long-term operation under large loads and harsh environments;

Special industrial rail transportation equipment: such as mobile devices in extreme working conditions such as metallurgical plants and power plants.

The DRS wheel system made of ductile iron GGG 70 not only greatly improves the load-bearing strength and service life, but also provides more stable and efficient operation guarantees for various industrial equipment. For users who pursue high performance and low maintenance costs, this is a trustworthy industrial wheel solution.
