Determining the Weight of the Lifting Table

Nostopöydän painon määritys

A 1,000 kg lifting table weighs 185 kg, where the size of the table top is 80 x 135 cm. The lifting height for the table is 82 cm. Determine the table size 100 cm x 200 cm weight when the lifting capacity is 2000 kg. One manufacturer reports this as a weight of 350 kg and a lift height of 110 cm.

Calculation

We will first calculate the task in detail, but later with row data, of which I will present the model at the end.

1.1 = 1.25

1 - 1.25 - 1.6 - 2.0

Lifting Capacity           Weight                 Calculated weight

   kg                                 kg                        kg             

 1 000                              185                      Known weight

 1 250                                 -                        1.08 x 185 = 200

 1 600                                 -                        1.08 x 192 = 216

 2 000                                 -                        1,08 x 205 = 233  Lifting height 82 cm

The table length increases from value 1.25 (135 cm) to value 2.00 = 1.1² = 1.21.

1.25    -   1.60   -    2.00      

135 cm - 160 cm - 200 cm

  1     x     1.1    x      1.1      

1,21

The width of the table increases from value 0.8 (82 cm) to value 1.0 = 1.1

     0.8   -     1.0

1.25 x 82 cm = 102 cm

1 x 1.1

The table rises 1.34 times higher  =>  factor 1.1 * 1.03 = 1.166

0.8    -   1.0   -    1.25  

  82 cm - 102 cm - 110 cm

1.0    -     1.1   -    1.03  

110 cm / 82 cm = 1.34

1 x 1.1 x 1.03 = 1.13

82 cm => 102,5 cm = 1.1                   (1,0328³ =1.1)

102,5 cm => 110 cm = 1.03        (7.5 cm = 1/3 x 25 cm)

Final Conclusion

Four dimensions increase having factor 1.1 and from lifting height once a factor 1.03.

185 kg x 1.08³ x 1.1⁴ x 1.03  = 351 kg

We can expect the quality and safety have remained at the same level in both table sizes.
