What should you pay attention to when testing wooden pallets?

Millele peaksite testimisel tähelepanu pööramapuidust kaubaalused?

Paindetugevuse testpuidust kaubaalusedon horisontaalselt toetada the longitudinal beams at both ends of the pallet, apply concentrated loads to two specified positions on the wooden pallet panel, and measure the bending deformation of the pallet after being compressed. The specific test method is as follows: According to the simplified In the form of support beams, place the flat pallet on the lower bolster, align the inner side of the pallet longitudinal beam with the two inner sides of the lower bolster, and the distance between the two inner sides of the lower bolster is the support distance. The lower corbel for support is a rectangular empty box made of two No. 10 channel steels butt-welded. Its length should be slightly larger than the length of the pallet. Then, place the center line of the pallet panel to the position of a quarter of the support distance on both sides. On the top, place the two corbels (upper corbels) for loading. The two upper corbels used for loading are made of seamless steel pipes with an outer diameter of 76mm and a wall thickness of 6mm. Their length should be slightly longer than the length of the pallet. The puidustkaubaaluspaindetugevuse testi saab läbi viia 3-5 tonnise survekatse masinaga. Muude mõõteriistade hulka kuuluvad sihverplaadi indikaator, niiskusesisalduse mõõteriist, terasmõõdulint, plumbbob jne. Katse ajal asetatakse kaubaalus survetestimismasinale asendisse. Ülemisele korbelile rakendatakse rõhu kaudu kontsentreeritud koormust. plaat ja laadimiskiirus on 10 kg/s. Kui koormus ületab 1,5-kordset puitaluse kandevõimet, mõõdetakse katte keskmise osa läbipaine kaubaaluse all.
