Light Weight Electro-Mechanical Drills

The ILTS-130 series, lightweight electro-mechanical core drills, have been operated in various locations. Some are as short as 1.4 m and as light as 20 kg, yet capable of taking a 0.4 m length ice core in one minute, with a power input of 400 W. They are suitable for drilling to 3 m depth. An extend...

Description
Summary:The ILTS-130 series, lightweight electro-mechanical core drills, have been operated in various locations. Some are as short as 1.4 m and as light as 20 kg, yet capable of taking a 0.4 m length ice core in one minute, with a power input of 400 W. They are suitable for drilling to 3 m depth. An extended version, 2.4 m in length and 28 kg in weight, took a 1 m length ice core in 2 minutes, during a laboratory test. This drill will be used in 1983 in Antarctica to replace a drill, which, in 1980, cored a 100 m hole in 44 h and another 143 m hole in 81 h. The basic design of the ILTS-130 series is described. This article is from 'Proceedings of the International Workshop/Symposium on Ice Drilling Technology (2nd) Held at Calgary, Alberta, Canada on 30-31 August 1982,' AD-A156 733, p33-40.
