When were Trip hammer invented?
James Nasmyth invented it in 1839 and patented in 1842. However, by then forging had become less important for the iron industry, following the improvements to the rolling mill that went along with the adoption of puddling from the end of the 18th century.

Hydraulic hammer supply hoses that bounce or hop around excessively are common indicators that the nitrogen chamber needs to be recharged. This puts the hammer at risk, lowers impact power and causes hammer supply hoses and tube connections to loosen and leak.
