Examination of the design of the lifting table scissor
Scissor lift table is used for vertical movement of cargo. The table consists of the loading platform, a base, scissor type lifting system and hydraulic cylinders. Payload table - 1500 kg.
Working height of the table lift - 5500 mm. The height of the lift folded - 800 mm. Dimensions platform: length 2500 mm, width 2000 mm.
lifting system elements are made of square tubes 140h100h6 mm. The diameter of the connecting shaft - 23 mm.
During operation of the product occurred collapse and destruction of the tube walls (cut) axis.
Load, impact and combinations thereof
load values were set in accordance with the technical specifications and include:
1. gravity load product
2. cargo weight, the load capacity of the table declared by the manufacturer.
After all the stress on individual loadings were created linear combinations of loads to which each of the loadings entered with the corresponding coefficients.
