It seems like they could be doing a lot more to automate that process, even in their own back yard there. For instance that sand shaker, they could drive it off an electric motor with some sort of eccentric. It's not like they don't have skills to make whatever they want there.
You gotta remember, Pakistan is full of cheap labour, so any automation you install puts a family member out of work. Plus, electricity there is expensive, but the labour is dirt-cheap.
A friend was buying Indian-built "Metex" engines and selling them in Australia and making a good killing out of them. The Metex was a copy of the early low-speed Lister diesel engines.
He said the Metex foundry was on a par with the Pakistani/Indian YouTube videos - guys in flip-flops and bare feet jumping over casting boxes whilst carrying a ladle of molten iron!
But he said the interesting part was, there was a Grove manufacturing facility not far away that he inspected. The Grove facility was producing truck-mounted cranes, and the yard contained several new rigs ready to go.
However, inside the factory, the employees were lifting heavy components around with many guys hanging on to ropes and pulley blocks! He said to the factory manager, "You've got a yard with new cranes out there! Why aren't you using one of them in the factory!?"
He said the manager looked genuinely shocked, and he replied, "But what would these men do for work and income, if I replaced them all with a truck crane?"
