What kind of cargo do the vans carry from the information in the following memo?
The vans normal load is usually nine per square yard. In…vehicles, which are very spacious, maximum use of space is impossible, not because of any possible overload, but because loading to full capacity would affect the vehicle s stability. So reduction of the load space seems necessary. It must absolutely be reduced by a yard, instead of trying to solve the problem, as hitherto, by reducing the number of pieces loaded. Besides, this extends the operating time, as the empty void must also be filled… On the other hand, if the load space is reduced, and the vehicle is packed solid, the operating time can be considerably shortened. The manufacturers told us during a discussion that reducing the size of the van s rear would throw it badly off balance. The front axle, they claim, would be overloaded. In fact, the balanve is automatically restored, because the merchandise aboard displays during the operation a natural tendency to rush the the rear doors, and is mainly found lying there at the end of the operation. So the front axle is not overloaded.
The lighting must be better prote ted than now. The lamps must be enclosed in a steel grid to prebent their being damaged. Lights could be eliminated, since they apparently are never used. However, it has been obsered that when the doors are shut, the load always presses hard against them as soos as darkness sets in, which makes closing the doors difficult. Also, because of the alarming nature of darkness… It would therefore be useful to light the lamp before and during the first moments of operation.
For easy cleaning of the vehicle, there must be a sealed drain in the middle of the floor. The drainage hold s cover, eight to twelve inches in diameter, would be equipped with a slanting trap, so that fluids can drain off during the operation. During cleaning, the drain can be used to evacuate large pieces of dirt.
