It is fitted with a four-speed transmission system, whilst the winch mechanism utilises a planetary gear design, with braking and clutch operations controlled via an eccentric cam handle. The drill bit is driven by two hydraulic cylinders for stepless feed, with a maximum upward thrust of 5,580 kgf, supporting 360\u00b0 multi-angle inclined hole drilling operations.<\/p>\n<figure id=\"attachment_6183\" aria-describedby=\"caption-attachment-6183\" style=\"width: 1000px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.wodetec.com\/products\/drilling-rig\/e90r-portable-diamond-core-drilling-rig.html\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6183\" src=\"https:\/\/www.wodetec.com\/engineering-equipment\/wp-content\/uploads\/2026\/09\/Diamond-Core-Drill-Machine-for-Soil-Investigation-and-Geotechnical-Engineering.jpg\" alt=\"Diamond Core Drill Machine for Soil Investigation and Geotechnical Engineering\" width=\"1000\" height=\"667\" \/><\/a><figcaption id=\"caption-attachment-6183\" class=\"wp-caption-text\">Diamond Core Drill Machine<\/figcaption><\/figure>\n<p>The Core Drilling Rig\u2019s hydraulic system is fitted with a variable-displacement vane pump, with a maximum operating pressure of 105 kg\/cm\u00b2; the 370 mm hydraulic sliding base enables the entire drill rig to be repositioned, facilitating alignment and withdrawal from the borehole. It comes as standard with a four-column drill tower, featuring three layers of reinforcement. The drill tower has a lifting height of approximately 5.6 metres, and the maximum drilling depth under NW casing conditions is 100 metres. The machine has a compact design, with a total weight of 1,300 kg including the skid and power unit. It strikes a balance between drilling performance and ease of movement, making it a reliable piece of equipment for engineering geological survey and sampling operations.<\/p>\n<figure id=\"attachment_6171\" aria-describedby=\"caption-attachment-6171\" style=\"width: 1000px\" class=\"wp-caption alignnone\"><a href=\"https:\/\/www.wodetec.com\/products\/drilling-rig\/e90r-portable-diamond-core-drilling-rig.html\"><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-6171\" src=\"https:\/\/www.wodetec.com\/engineering-equipment\/wp-content\/uploads\/2026\/09\/Diesel-Powered-Geological-Drilling-Rig-for-Rock-Core-Sampling.jpg\" alt=\"Diesel Powered Geological Drilling Rig for Rock Core Sampling\" width=\"1000\" height=\"1500\" \/><\/a><figcaption id=\"caption-attachment-6171\" class=\"wp-caption-text\">Diesel Powered Geological Drilling Rig<\/figcaption><\/figure>\n<\/div>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>This Skid Mounted Core Drilling Rig for Engineering Site Investigation, is specifically engineered for diamond core drilling in geotechnical surveys.
