Long-Term Durability
Industrial-grade components withstand harsh construction environments. Low failure rates and simplified maintenance protocols ensure maximum uptime throughout the equipment lifecycle.

Q: What is the maximum rebar grade this machine can handle?
A: Standard units process Grade 60 (420 MPa) steel reliably. High-torque models accommodate Grade 75 or 80 rebar when you use appropriate mandrel diameters to prevent internal micro-cracking during the bending cycle.
Q: How often does the gearbox oil require replacement?
A: Perform the first oil change after 50 operating hours on new machines. Subsequent changes occur every 500–800 working hours depending on ambient temperature and load conditions. Regular maintenance preserves transmission efficiency.
Q: Can the machine bend multiple bars simultaneously?
A: Yes, for smaller diameters like φ6–10mm, you can bend multiple bars in one cycle. Ensure the combined cross-sectional area stays within the machine's single-bar maximum rating to maintain bending accuracy and equipment safety.
Q: What causes motor overheating during operation?
A: Overheating typically results from voltage drops in long extension cables on construction sites or attempting to bend rebar exceeding the machine's rated capacity. Use adequate gauge power cables and verify diameter specifications before processing.
Q: Does the machine require a specific foundation?
A: While designed for portability, place the unit on level, compacted surfaces or concrete pads. Proper foundation support prevents frame twisting and maintains bending accuracy during high-torque cycles, especially when processing larger diameter bars.
Q: How quickly can new operators learn the system?
A: The intuitive PLC touch screen interface enables most operators to achieve proficiency within one hour of training. Parameter storage functions and visual prompts simplify the learning curve significantly compared to manual bending methods.
Q: What maintenance schedule should we follow?
A: Beyond regular gearbox oil changes, inspect bending pins and mandrels weekly for wear. Check electrical connections monthly. The low-maintenance design minimizes downtime, but preventive inspections extend component life and ensure consistent output quality.
