If a company uses metal drums for any industrial purpose, then they might want an automatic wench capable of lifting a metal drum plus its contents and then dump it into a vat or drain with a reasonable degree of precision. A drum lifter and dumper is not a pouring application, but it is a neat way to dump a fairly large volume of liquid material into a target of appropriate size. Consider this cost-efficient solution to speed production and cut down on heavy lifting by humans.
If the target is in a more remote location and is not accessible by a walkway, then this might be the only real fix. A factory floor is kept tidy and safe by the using of a strong wench able to upturn a drum and allow gravity to empty its contents. Keeping humans safely away is especially useful in minimizing exposure to artificial substances.
