Ramji Hansraj Kamani (Gujarati: રામજી હંસરાજ કમાણી; 21 February 1888 – 27 June 1965) also called Ramjibhai, was an Indian entrepreneur and industrialist born in the village of Dhari in the Amreli district of Saurashtra, Baroda State.

Kamani Engineering Corporation (KEC) also manufactured a unique and innovative road roller with the trade name Tractmount  — the design created a light-weight standalone road roller which could be easily transported in a truck and could be mounted on by a tractor for use at its destination.

This was augmented by a second unit in Jaipur, Rajasthan[2] and by 1967, KEC was supplying three-fifths of India's demand for transmission towers.

[1] By the 1970s, the Kamani group as it came to be known, consisted of seven companies with several manufacturing units in Bombay, Bhavnagar and Jaipur, and doing business in varied fields ranging from metals to rubber and chemicals to jewel bearings not to mention power, in both national and global markets.

Completing its project commitments while incurring heavy losses and unable to clear its debts, the company was auctioned by the Maharashtra government in 1982 for recovery of dues and was acquired by the RPG Group[1] and in 1984, renamed KEC International.
