Last year, we received a call from a customer in the Philippines asking about bridge cranes. They indicated that they were in the steel industry, producing hot-rolled steel plates, I-beams and billets for construction. Due to adjustments in production schedules, this customer plans to purchase a new 10-ton overhead crane.
The customer's production plant mainly carries out cutting, welding and stacking operations of steel plates. After on-site communication and mapping, we identified the following key requirements:
| Requirements | Specific parameters/requirements |
|---|---|
| Rated lifting capacity | 10 Ton |
| Span | 16 Meters |
| Lifting height | 12 Meters |
| Job level | A6 |
| Control mode | Remote control + cab dual mode (remote control for daily flexible operation, cab for hot area or complex lifting) |
| Positioning Accuracy | Requires anti-sway control to avoid steel plates hitting workers or equipment |
The lifting environment in a steel mill is far from ordinary workshop. Therefore, there are other factors that need to be taken into account when providing lifting solutions for steel mills to avoid safety risks to the life and safety of the equipment in the final lifting solution.
| Challenge | Specific description | Impact on cranes |
|---|---|---|
| High temperature radiation | Temperatures in the vicinity of steel plate cutting and welding areas can reach 50-60°C, and the presence of hot steel plates for lifting | Motors, cables, control components are easy to aging; wire rope lubrication volatilization, shortening life |
| Dust and Iron Chips | Large quantities of grinding dust, oxidized skin and iron filings in the workshop | Conductive dust can contaminate electrical cabinets and cause short circuits; iron filings can get stuck in wheels or gearboxes |
| Continuous high load operation | Average number of hours per crane operation | Ordinary work class cranes are prone to structural fatigue or motor overheating |
| Space constraints | The original 5-ton crane had a low rail height and there were pipes and ventilation ducts above the workshop | New cranes must be installed under the existing plant structure without altering the main roof beams |
In response to these challenges, our technical team had several video communications with the client to discuss the specifics, and ultimately produced a detailed proposal for the client to view. The customer was very satisfied with the initial proposal, but indicated minor changes, after which we finally supplied a 10 ton double girder overhead crane. Cranes in the iron and steel industry work harder, single girder overhead travelling crane in 10 tons, span 16, and long-term continuous operation under the stability and rigidity of the poor, under long-term use is prone to deflection and gnawing rails. The double girder structure is not only more stable under the same working conditions, but also provides an independent maintenance platform for the hoisting mechanism.
| Components | Standard Configuration | Customized improvements for steel mills |
|---|---|---|
| Main beam | Double girder box structure | Adopting thickened steel plate and internal partition to improve fatigue resistance; overall rust removal + high temperature resistant epoxy paint |
| Lifting mechanism | 10 ton wire rope hoist | Equipped with high-temperature-resistant steel wire rope (with steel structural core); hoist motor with H-class insulation |
| Electrical control system | Variable frequency + PLC | Added wide voltage regulator module; control cabinet IP54 protection with positive pressure cooling filter fan |
| Security Configuration | Basic Limit + Overload | Added: anti-sway control module, hoist overspeed switch, motor temperature monitoring |
| Tracks and Slip Lines | General purpose | The rail is fixed by pressure plate with buffer pad; the sliding contact wire is selected to be high-temperature-resistant and dust-proof type |
