On 30th November 1880, lafrnnr Joseph Clark got patent protection for a convenient invention namely Excavator with the Patent No. US234851A in USPTO. He came up with this with the aim of reducing the cost, time and labour which is required in any construction work whether for road, railway or mining, so as to make the work quite easier.
Today excavator becomes the name of a useful equipment when it comes to construction work for various types of industries ranging from mining, forestry, road or building construction works etc. Now-a-days we can find different types of excavators depending upon the type of the works in industry. They are mainly used for digging, cutting or for trenching purposes.
