Counterweights are one of the applications where LKAB Minerals has supplied MagnaDense for many decades. Counterweights typically require a specific mass within a limited volume. The use of high-density aggregate MagnaDense, sourced from LKAB Minerals’ own resources, ensures long-term availability and consistent quality while enabling its use both as an aggregate in high-density concrete and as loose ballast to fill steel shells.
Counterweights with MagnaDense are used in:
-
Bascule bridges
-
Horizontally opening bridges
-
Excavators
-
Household appliances
-
Infrastructure doors (such as sluices and docks)
-
Tractors and other agricultural machinery
-
Cranes and hoists
-
Robotics for livestock facilities
-
Filing cabinets
MagnaDense is reliably available from LKAB Minerals’ own mining operations, sourced from its own resources, ensuring long-term availability and consistent quality. It is suitable for both precast element production and in-situ casting in large infrastructure projects.
Key benefits of MagnaDense:
-
Natural mineral with no risk of harmful substances or leaching – safe to handle and use
-
Complies with EN 12620 for use as an aggregate in concrete
-
Consistently high quality in both density and particle size distribution (PSD), enabling automation
-
Easy to fill compared to steel units that require manual handling
-
No movement or rattling in applications such as bascule bridges under traffic loads
-
Reliable availability from LKAB Minerals’ own mining operations
-
Suitable for both precast element production and in-situ casting in large infrastructure projects
High-density concrete with MagnaDense can reach densities of up to 4 t/m³. When mixed with other steel-based materials, even higher densities can be achieved.
LKAB Minerals provides MagnaDense to concrete counterweight manufacturers around the world. With global stock locations and owned mines in Northern Sweden, we ensure a reliable supply of high-quality heavy aggregate, enabling you to produce counterweights at your preferred location.
