Tsubaki provides the best solutions for steelmaking equipment--Applications in the Stock Yard

Stock Yard

The role of the material yard is the unloading and storing of iron ore, coal, and limestone from ships, and then supplying these to the sintered ore and coke production processes in the pig iron plant.

Continuous unloaders

Unloaders use buckets to unload bulk material, e.g. coal and iron ore, from ships. In particular, the continuous unloader effectively unloads bulk material in a short time, enabling major demurrage savings.

Power Cylinders/Overload Protectors

Power Cylinder

Tsubaki Power Cylinders are electric cylinders that can be put in service with just simple electric wiring.

This means simple maintenance, eliminating the need for cumbersome piping required by hydraulic and pneumatic types. Standard types include both small and large thrusts designed for safe operation with built-in protectors, plus various options. U Series Power Cylinders demonstrate outstanding performance where much larger loads are required.

Mechanical Overload Protectors

Reclaimer swivel ring gears are driven by pinions. Tsubaki’s mechanical protection equipment instantly prevents overloads due to clogging of coal or debris in the gears even on large machines.

Chain scraper reclaimers

Designed specifically to reclaim ores and other bulk materials piled in storage yards. The material is delivered to the next process. Scrapers attached to the chain deliver the material.

  • Reclaimer chains

Reclaimer chains

With reclaimer chains, abrasive substances tend to infiltrate between bush and roller or into outboard rollers. When roller rotation becomes faulty or wear occurs between bush and roller, the chain comes to the end of its service life.

Tsubaki chains achieve longer service life by employing bearing rollers with high debris resistance.
