Key Selection Points
Project Requirements: For interior finishing, choose the remote-controlled folding model; for exterior wall construction, choose the bridge-type/disc-lock type. Disc-lock type is essential for bridge projects (a client in Baoding experienced issues with the bridge-type model's inability to turn during interior construction).
Material and Craftsmanship: Primarily recommend Q355B high-strength steel (strength exceeds Q235 by 30%, deformation under the same load is only 1/2.3); hot-dip galvanized layer thickness ≥80μm (inspected on a per-piece basis).
Functional Configuration: Dual motors increase efficiency by 40% (cost increases by 25%); intelligent control with automatic alarm over 3 degrees Celsius; APP monitoring requires regular sensor calibration.
Safety Redundancy: 100% pass rate for dual limit switches; overload protection triggered by 1.2 times rated load (quarterly spot checks).
Cooperation Mode: Short-term projects are recommended to lease (daily rental 200-500 RMB), maintenance records need to be checked (a case of substandard leasing was found in Tangshan).
Manufacturer Inspection: Focus on production qualifications and testing reports (a small factory's weld strength was only 60% of the national standard).
Product Comparison
Safety: A single upright of the disc-lock type withstands a static load of 5.8 tons (destructive testing); 70% of accidents involving the coupler type are due to insufficient torque.
Erection/Disassembly Efficiency: A three-person team can assemble 200 cubic meters per day with the disc-lock type, while the coupler type takes 30% longer (requires a "click" sound to confirm placement).
Applicable Scenarios: Stable operation of bridges at a height of 200 meters; folding platforms can be deployed in 10 minutes, 5 times more efficient than traditional methods.
Cost: The total lifecycle cost of the disc-lock type is 28% lower than that of the coupler type (saving 12% of the total cost for a 100,000 square meter project).
