Hook adaptation requirements cover dimensional fit,structural strength,engagement reliability,and installation norms,with no enterprise-related information included.For standard scaffold ledgers(outer diameter 48.3mm,wall thickness 3.6mm),hook inner width should be 49–50mm,with a clearance of 0.5–1.2mm to ensure smooth installation and minimal lateral sway.Hook bending radius must be≥3 times the hook plate thickness to avoid stress concentration and fatigue cracking.Hooks must be made of Q235B/Q345B steel with thickness≥2.0mm,fully welded to the plank body with no cracks or incomplete fusion,and able to withstand rated shear and tensile loads without plastic deformation.Hooks must fully wrap and lock onto the ledger,with no partial hanging;the hook opening must face downward and engage completely,and anti-slip or locking structures are recommended to prevent accidental disengagement under vibration or lateral force.Installation requires uniform hook spacing,full contact between hook inner surface and ledger,and no overhang exceeding 150mm at plank ends.Regular inspection of hook wear,deformation,and welding integrity is required to maintain adaptation performance.
