The posts in this blog focus primarily upon specifications of earth moving equipment used in high pressure gas pipeline construction and the parts / spares compulsory keeping these machines in true functioning order which are subjected to severest bashing of the elements including work in environmental extremes of temperature ranging from 0° to 52° Celsius, extreme slopes crossing the psychological threshold of 35°, service in muddy, marshy, water logged areas, deserts and salt plains.
