Hydraulic system - Powered swiveloptionsBase machine has 1600 kg. high power hoisting by hand operated winch, butCan be supplied with a hydraulically driven free-fall winch as an alternative, allowing all standardcable tool operations in addition to all the rotary functions. General set-up - on site UgandaDiesel powered for reliable hand starting & long life; engines from 6 to 18 hp.10 foot stroke 60mm (2-3/8") or 70mm (2¾") dia. flush jointed drill rods.All flushing methods supported including modified stable foam, air & mud and down-the-hole (DTH)hammers - 2" or 3" sizes suggested operating at low pressure (7 bar/100 psi) using standardcontractors' 1 or 2-tool compressors.Portable foam generators, foam and auxiliary compressors supplied. Good foamFolds down to form a trailer carrying all the equipment. The long format gives stable fast towing.Can be moved by hand between village sites off road, and is canoe portable.

It is usual to take about80% of the available hoist capacity and convert this to depth by calculating the weight of the drill string.The Forager hoist has a Safe Working Load (SWL) capacity of 1600 Kg. (3500 lbs) and the 3-metre rodsweigh 25 Kg each. So 80% of 1600 divided by 25 Kg = 51 rods, or 510 feet (153 m). However, one 250 Kgdrill collar weighs as much as 10 rods, and the drive head weighs 50 Kg, so the net effective drilling depthwould then be 390 feet feet (120 m). If it is necessary to use more than one drill collar the effecivedrilling depth is again reduced.When steel casing is employed, the weight of casing that the rig can handle may dictate the depth. A 10-ft. length of 4-inch steel casing with a 6mm wall weighs 50 Kg, or twice as much as our drill rods. Thismeans that the rig would be limited to a cased hole depth at which it could safely control the lowering ofsuch casing. On the basis that our equipment is intended mainly for use in the tropics, we suggest usingplastic casing when possible, in order toavoid problems caused by corrosion of steel casing. Plastic casingis easier and lighter to handle, but is not as tough as steel, and cannot normally be driven. It is necessaryto use plastic casing differently from the use of steel.The depth to which it is possible to drill is also a function of the skill and experience of the driller, andthe nature of the material being drilled. The rig manufacturer cannot provide a guarantee as to drillingdepth. He can only offer a machine with stated abilities in terms of power, torque, speed and hoistingcapacity.
