Costs

As according to the calculations, the total volume of HSLA steel used is 18.084*10^(-3) m^3 and cost of 1 m^3 is £ 35277.77.

So, therefore the cost of the total HSLA steel to be used is = 35277.77*18.084*10^(-3) GBP

= £637.96

Cost of the manufacturing of special I-Beam = £100

Cost of 16 nuts and 16 bolts is as follows;

Cost of A2 stainless steel M12*110mm bolts = £ 19.50

Cost of A2 stainless steel M12 hex nuts = £ 2.70

Cost of chain hoist = £ 150.49

Cost of rollers = £ 48.69

Cost of rubber sphere = £20.99

The total cost of crane comes out to be £ 980.33. As this is the cost of single K-crane, the cost per crane can be brought down depending on the number of cranes ordered.

The selling price of this crane is £1349.99 giving us the profit of approximately £370 per crane. Assuming, if we get the order for 100 cranes, we can easily make profit more than £37,000.
