A port ship loader is a high-capacity bulk-handling machine used to load materials such as coal, ore, grain, or fertilizer onto vessels at port terminals. Mounted on rails, these loaders require durable and precise rail wheels to ensure smooth, stable, and efficient travel along the quay.

For port ship loaders, wheels are generally offered in single-flange or double-flange designs:
Single-flange wheels reduce rolling resistance and are ideal where track alignment is strictly maintained.
Double-flange wheels provide superior guidance and stability, particularly in curved track sections or where lateral forces are higher.
A proven choice in such demanding environments is the Demag DRS wheel block system. The DRS wheel block is a complete, modular travel unit integrating a precision-engineered wheel, rugged housing, and high-performance bearings. It offers multiple operational advantages:
Exceptional load capacity – designed to handle heavy ship loader structures with ease
Low rolling resistance – improves energy efficiency and reduces drive motor wear
Marine-grade corrosion protection – resists salt spray and harsh coastal conditions
Precision guidance ensures accurate movement along straight and curved rails
Modular design – simplifies installation, inspection, and replacement without lengthy downtime
Long service life – reduces maintenance costs and increases operational reliability

Beyond ship loaders, DRS wheel blocks are widely used in port cranes, stacker-reclaimers, transfer cars, and other heavy-duty rail-mounted machinery. For port operations, their robust design and smooth operation directly contribute to increased uptime, reduced maintenance, and safer, more efficient bulk loading.
Demag DRS-M 160 wheel block: 7-ton load capacity for heavy-duty box stacker cranes, ideal for multi-layer stacking & thick-walled/semi-finished boxes, ensuring stable operation & low maintenance.
The Demag driven wheel block system is a high-performance, modular wheel unit widely used in cranes, transport systems, machine tool gantries, transfer carts, and heavy-duty handling applications.
Demag wheel blocks for cleanroom cranes have some special requirements in design and application, mainly to ensure efficient and safe operation in highly controlled environments such as cleanrooms.
