Dando has recently supplied another Multitec 4000 into Bolivia, as the compact multipurpose rig continues to prove a big hit in Latin America.
Equipped with a 111hp engine and 4 Tonne main winch, the rig has been acquired by an electrical company in Bolivia who will be using it for SPT, coring, Shelby tube sampling and permeability tests across a range of geotechnical projects.
This particular rig also features a recovery winch, 3 position carriage and a wireline winch mounted on the headache post.

One of Dando’s commissioning engineers has just returned from a trip to Columbia visiting a greenfield site near San Martin just south of Bogota. The aim of the trip was to find out if the Dando Terrier rig – complete with rotary mast – was capable of drilling with a simultaneous drilling and casing system (Symmetrix) and to discover the productivity that could be achieved.
Results were encouraging; it seems clear that the tough, compact rig using the 4” Symmetrix system is eminently capable of meeting the customer’s needs in the production of 3 holes per day to a depth of 12 metres. Indeed it may be possible to drill more but clearly this is dependent on the length of the working day and the application and efficiency of the drill crew.
