In the era of Industry 4.0, we adhere to the philosophy of "human empowerment in key processes" and Exclusive showcase of our manufacturing process for spider arm cranes— from steel cutting to full-machine debugging, 15 senior technicians (average experience over 12 years) oversee core stages, ensuring 100% factory qualification through "naked-eye precision + mechanical standards" dual guarantees.

1. Steel Material Warehouse

We strictly select imported S690QL special steel. Material inspectors with 20 years of experience visually check each batch for uniformity of grain size, rejecting panels with impurities to ensure the boom’s tensile strength ≥ 890MPa.

2. Welding Workshop

Welders with over 15 years of experience use high-precision welding equipment for multi-layer, multi-pass manual welding. Each weld is rechecked via magnetic particle inspection and a 10x magnifier, certified to meet international welding standards (ISO 9606-1).

3. Engine Assembly Line

Our Changchai engine units are manually debugged by an assembly team. Using their expertise in "sound-based running-in assessment", they judge cylinder running-in status. Every unit undergoes -30°C cold start + 50°C high-temperature continuous operation tests, with a failure rate < 0.3%.

4. Full-Machine Assembly Process

National-level fitters lead the final assembly, calibrating outrigger Horizontal Reading with micrometers to ensure errors are strictly controlled within ±0.05mm. Each unit takes 72 hours to assemble — far exceeding industry averages.

5. Finished Product Quality Inspection

Three quality inspectors cross-verify each device，72-hour load test data is uploaded to the cloud for customer traceability.

Craftsmanship Beyond Automation: Where Human Expertise Meets Industrial Precision.

Every spider boom crane is a testament to 20 years of relentless pursuit of perfection — because true quality is forged not just by machines, but by the hands and hearts of those who understand it best.For more behind-the-scenes manufacturing visuals or technical specifications, contact us today.
