Transport Car Category Overview
The Transport Car is the backbone of in‐plant material handling in steel mills, foundries, and metal processing facilities. Haijie Machinery’s Transport Car series offers robust, high‐capacity vehicles—available in rail‐guided or rubber‐tired configurations—to move heavy loads such as ladles, billets, blooms, and finished coils with precision, safety, and minimal cycle times. Engineered for harsh steelmaking environments, our transport cars deliver reliable performance, modular scalability, and advanced automation options to optimize production flow and reduce downtime.
Haijie Transport Cars consist of a heavy‐duty chassis, drive motors, guidance and braking systems, plus operator interface or remote control station. Models range from 20 t to 300 t payload capacity per car, with customizable dimensions, wheelbases, and guidance methods:
Rail‐Guided Transport Car (RGT): Steel wheels running on dedicated rail tracks ensure precise path control for repeatable, collision‐free travel. Typical loads include ladle cars (up to 250 t) and billet cars (up to 100 t).
Rubber‐Tired Transport Car (RTG): Pneumatic or solid rubber tires provide flexibility to traverse multiple lanes or variable‐gauge tracks, ideal for coil and bundle handling. Capacities range from 20 t for coil cars to 80 t for heavy bundle cars.
Each transport car features a welded steel frame, sealed wheel bearings, and an integrated power source—options include DC batteries, cable reel power, or diesel‐electric hybrid drives. Control systems are built around PLCs with optional wireless remote‑pendant, HMI touchscreen, or full integration into plant SCADA.
High Load Capacity & Stability
Precision‐machined bogies and self‐aligning wheelsets distribute loads evenly, reducing track wear and ensuring stable motion under full payload.
Flexible Power Options
Battery‐Electric: Lithium‐ion or lead‐acid battery packs with on‐board chargers support 8–12 hours of continuous operation per charge.
Cable Reel: Slip‐ring assemblies or festoon systems deliver unlimited run time for intensive cyclic use.
Diesel‐Electric: Low‐emission Tier 4 engines coupled with electric drives for maximum range in remote areas.
Advanced Guidance & Safety
Rail‐Guided: Flange guides and track switches for multi‐route flexibility.
Laser or RFID Navigation: Wireless positioning for RTG models to follow fixed or dynamic routes marked by floor tags or wall reflectors.
Redundant Braking: Hydraulic disc brakes plus spring‐applied failsafe brakes meet SIL 2 safety standards.
Modular Design
Swappable battery modules, plug‑and‑play wheelsets, and standardized couplers simplify maintenance and fleet expansion.
Operator Comfort & Ergonomics
Air‐ride operator cabin option with climate control, anti‐vibration mounts, and 360° camera system for enhanced visibility and reduced operator fatigue.
Optimized Material Flow
Fast acceleration and deceleration profiles minimize cycle times; coordinated multi‐car platooning reduces traffic congestion in plant aisles.
Reduced Total Cost of Ownership
Durable components, centralized lubrication, and remote diagnostics enable proactive maintenance, extending service intervals to over 10,000 hours.
Enhanced Safety & Compliance
Integrated light curtains, obstacle detection sensors, and audible alarms meet international safety regulations (CE, OSHA).
Scalable Fleet Management
Central fleet management software provides real‐time location, battery state of charge, and maintenance alerts, supporting fleets of 5–50 cars.
Environmental Sustainability
Battery‐electric models produce zero on‐site emissions; regenerative braking recovers up to 15 % of kinetic energy back to the battery.
Ladle Transfer
Shuttle molten steel between EAF/BOF and casting areas with minimal heat loss and no human proximity hazards.
Billet and Bloom Handling
Transport newly cast billets to roughing stands or bloom shear lines in integrated casting‐rolling complexes.
Finished Coil Distribution
Move coiled steel from cold mill exits to storage bays or shipping docks with zero strip damage.
In‐Plant Logistics
Link melting shops, rolling mills, and coating lines in high‐throughput steel plants or heat‐treating facilities.
Multi‐Car Platooning
Synchronized convoy control for groups of cars, reducing operator requirements and maximizing throughput.
Automated Guided Vehicle (AGV) Upgrade
Add LiDAR, SLAM navigation, and AI path planning for fully autonomous operation.
Specialized Load Fixtures
Custom cradles, ladle fork tongs, or magnetic lift units for non‑magnetic bundles, coils, or ingots.
Environmental Protection Packages
High‑temperature insulation, slag‐splash shielding, and corrosion‐resistant coatings for steelmaking furnace vicinity.
What guidance method is best for my facility: rail or RTG?
Rail‐Guided offers unmatched precision for repetitive routes; RTG provides route flexibility without fixed tracks. Choice depends on plant layout and process flow variability.
How long does it take to swap battery packs?
Under 10 minutes with quick‐release connectors and slide‑in modules; hot‐swap carts can further minimize downtime.
Can transport cars operate in extreme temperatures?
Yes. Standard models function from –20 ℃ to 60 ℃; optional cold‑pack batteries and heat‑resistant seals extend the range to –40 ℃ and 80 ℃.
Is operator training included?
Haijie provides comprehensive training covering vehicle operation, maintenance procedures, and safety protocols, either on‐site or at our demo center.
How is fleet maintenance managed?
Our fleet management software tracks usage data, schedules preventive maintenance, and issues automated alerts to ensure 24/7 operational readiness.
