Two Unmanned Grab Cranes for Baowu Shaogang’s Rotary Hearth Furnace
Two grab cranes use 3D scanning and automatic material recognition, with positioning and repeatability within 5 mm for the furnace project.
The project and its handling task.
Baowu Shaogang selected two unmanned grab cranes for its 250,000-tonne rotary hearth furnace project. The cranes were customized around the material-handling process and the plant’s automation requirements.
The systems combine 3D scanning, automatic positioning, recognition, obstacle avoidance and grabbing. Operating personnel can supervise from an office more than 1,000 m away, reducing the need to remain in the dusty handling environment.
Automate grab movements in a dusty steelmaking process.
Frequent material handling at a rotary hearth furnace exposes operators to dust and requires accurate repeat positions.
Scan the pickup area and determine the grab target.
Travel to the selected destination while checking obstacles and position.
Confirm discharge and record the completed cycle before the next task.

Questions before specifying a similar crane.
Can the same project crane be supplied for my site?
We customize the capacity, span, lifting height, attachment and controls to the load, building or yard layout and operating cycle. Material size and pickup variability is one of the inputs to review before final equipment selection.
How are certification, quantity and lead time agreed?
Single-crane and fleet enquiries are welcome. Define the destination and required standards in the enquiry. The project offer confirms certification and inspection documents, the quantity, drawing approval and manufacturing schedule, with the shipping and site-service boundaries.
What should acceptance and after-sales support include?
Agree the inspection plan, representative load and functional tests, operator training, maintenance instructions, spare-parts scope and fault-recovery procedures. For this application, include scanning, avoidance and recovery rules in the technical review.
Planning a similar lifting project?
Send your layout, load and operating requirements. We can develop a customized crane package and delivery scope for your site.
