Any lifting system will experience wear and tear in service. Frequent inspection is key to safe

working and lifting procedures. A few simple steps need to be followed when inspecting the

Transport Anchor system.

Inspection requirements:

The transport anchor is to be examined by a trained, professional safety expert

with at least one inspection per year. Under daily use one inspection after each shift is sug-

gested.

The inspector must look for damage and wear on the device. If damage is found the device

must not be used.

The receiver mouth width “h” must not exceed 1/2” (13mm). Whenever the width is h >

1/2” (13mm) the system must not be used.

Repairs or modifications on the transport anchor system of any kind - particularly

welding - are not permitted!

For safety, the screws may only be used once.

Safe working lifting procedures are to be exercised at all times

Receiver mouth width “h” must not exceed 1/2” (13 mm)

DESIGN EXAMPLE OF TRANSPORT ANCHOR

Conditions of Use : Screws inserted at 60° relative to lifted member grain direction; 2 lifting supports

System combination of two (2): 1/2” x 6 1/4” Kombi FT + Transport Anchor

Effective Withdrawal Capacity (Prw,α)

according to CCMC 13677-R:

Prw,α = ɸ KD · KSF · KG · KDynamic · 0.8 · [b · 0.84 · ρ)2 · d · lef · 10-6] / [sin2α + 4/3·cos2 α]

Relevant Parameters : Φ = 0.9

0.8 = adjustment factor to standard term loading

δ = material adjustment factor: 82 for ρ≥440 kg/m3; 85 for ρ<440 kg/m3

b = 1 for D.Fir-L, SPF and WRC

Ρ = mean oven-dry relative density (CSA O86, Table A.10.1) x 103 kg/m3

0.84 = adjustment factor of mean oevn-dry relative density to 5th percentile

value

d = outside screw diameter (mm) = 12 mm

lef = effective embedment length of screw (thread length—tip length(=d)) (mm)

= 145 - 12 = 133mm

α = screw angle = 60°

Applicable Modification Factors:

KD = load duration factor = 1.15 (short)

KSF = service condition factor = 0.67 (Assumed Green conditions, MC > 15%)

KDynamic = dynamic loading factor = 1/1.4 = 0.714

KG = group factor for 2 screws = (2)0.9 = 1.87

Calculation Effective Withdrawal

Capacity:

For D.Fir-L: ρ=490 kg/m3 ; b= 1 ; δ = 82 and α = 60°

P’rw,α = 11,354 (N) = 11.35 (kN) (per screw)

Prw,α = Prw,α · KDynamic · KG = 15.15 (kN) (per pair of screws)

Calculation of Maximum Lifting

Capacity (W) :

Max. Tensile Resistance of Screws = 24 (kN) · 2 = 48 (kN)

Max. rated resistance for transport anchor = 13kN · 2 = 26 (kN)

Max. Capacity of screws is min(48,26,Prw,α ) = 15.15 (kN) = 3400 (lbf)

Max Lifting Capacity Wmax=sin(60°)·3400=2945(lbf) -->

Wmax =3000 [lbf] (2 lifting pts)
