Hello, Kindly provide us with the prices of your various water well drilling rigs and shipping cost to west Africa. We intend to supplying the various municipal assemblies in Ghana with your portable drilling rigs for use in the rural communities. Also since we would be purchasing in large quantities, kindly state if there are any discount offers on buying a large quantity of the drilling rigs. Whilst thanking in anticipation, I remain Kindest Regards

what a dud of a design...how many strokes out of those hydraulic cylinders do you expect to get before you have to replace the seals & o-rings in those cylinders before they leak fluid all over the place? Goofy Germans always trying to reinvent the wheel in the hopes some folks will think they are some kind of engineering marvels...go look at a speed star or a bucyrus- erie and see how efficient mechanics in cable tools are...put a heavy string of tool on those hydraulic cylinders moving fast enough to be efficient and see how fast they fall apart!
