Ladle cranes are used to perform material transport between different machines in the rolling mills. In order to improve the precison of the position, they may incorporate with a rotating trolley to put the product correctly in relation to the conveyor.
Steel Plant Crane Features
Steel plant cranes (QDY&YZ model bridge foundry cranes) with hook mainly consists of main beam, hook trolley, crane traveling mechanism, cabin and electric controlling system, etc. Foundry crane is one of the main equipment in the continuous casting technology of steel making. It is mainly used transfer the pouring melted iron to the appointed place, and the thermal protective coating is added at the bottom of the main girder. The place where molten nonmetal material and red-hot solid metal is lifted. The casting overhead crane are heavy duty for 20-24hours working.
High Strength & Durability: Double girders and reinforced structure let it handle heavy, hot loads safely.
Precision & Safety: Rotating trolley helps position ladles exactly; safety measures reduce risk.
Continuous Operation: Designed for long, demanding work (24 hours) with redundant systems to avoid downtime.
Custom Fit: Span, capacity, control method, power, and other features can be tailored for your facility.

FAQs
A ladle lifting crane is used to transport molten metal or steel in the ladle between different stages of steel-making, such as from the furnace to continuous casting, or for auxiliary operations in rolling mills. It often includes a rotating trolley so the ladle can be precisely positioned relative to a conveyor or pouring station.
This crane can be built for capacities ranging from 5 tons up to 500 tons, and spans between 5 meters and 40 meters. These options allow matching facility layout and load sizes in steel mills.
Our clamshell buckets have capacities ranging from 0.5 cubic meters up to 30 cubic meters, customized according to your material density, crane capacity, and operational requirements.
The crane is classified as Working Class A7-A8 (FEM 4m-5m), which means it's designed for very heavy, continuous or nearly continuous duty operations. This ensures the components, motors, brakes, and structure are robust enough for long hours, high temperature, and heavy loads.structures.
It includes dual brakes on each mechanism for safety, soft-start frequency adjustable motors to reduce stress on start-up, limit switches to avoid over-travel in all motions, and other protection measures like overload limiters and emergency stops. These features improve safety and reliability.
