Conveying System

The DRS Wheel Block System covers a full load range of 2.75 to 40 tons, with two product series—DRS-M (model range 112-200, load capacity 2.75-10 tons) and DRS (model range 250-500, load capacity 16-40 tons)—to precisely match different pallet weights and stacker crane specifications.

1. Superior Heavy-Duty Load Capacity and Structural Rigidity

The wheel block features a high-quality cast housing and die-cast aluminum alloy construction, with a five-sided enclosed design that provides comprehensive protection for the traveling wheels and bearings while ensuring exceptional structural rigidity and tight dimensional tolerance control. Wheel rims are available in optional materials including ductile iron (GGG70), polyamide, or polyurethane. Ductile iron wheels offer self-lubricating properties, low friction, and high wear resistance, while polyurethane rims are tailored for high acceleration and low-noise requirements, boasting excellent static friction coefficients to prevent slipping during heavy-load startup. Equipped with large-size deep groove ball bearings or tapered roller bearings, pre-lubricated for life, the system fundamentally enhances stability and service life under heavy-duty operating conditions.

2. Balanced Precision Positioning and Easy Maintenance

An innovative mounting and locking mechanism eliminates the need for time-consuming readjustments during wheel block replacement, maintaining precise positioning even after servicing. Combined with a laser alignment system, it enables accurate calibration of multiple traveling units, ensuring millimetric positioning accuracy for stacker cranes during high-level operations. The DRS-M series is further equipped with a mechanical wear indicator, which intuitively displays wheel wear status via color coding. Inspections can be completed in a stationary state without relying on specialized equipment, significantly reducing maintenance costs and downtime.

3. Modular Design for Flexible Adaptability

The system offers four connection methods for seamless integration into the upper structure of various stacker crane models. Pre-drilled threaded holes facilitate the later installation of accessories such as guide wheels and rail cleaners, supporting future application expansion. Wheel rims are available in seven standard profiles and can be customized to meet specific customer requirements. Whether for rail-mounted stacker cranes or ground-based equipment, the system adapts to diverse operating environments and guiding needs.

Amid the wave of transformation toward high-density, automated, and intelligent warehousing and logistics, the DEMAG DRS Wheel Block System continues to drive stacker cranes beyond performance limitations through technological innovation. It empowers enterprises to build more competitive intelligent warehousing systems, solidifying its position as the preferred wheel block solution for heavy-duty, precision-focused warehousing applications.
