O'Brien delivers its biggest-ever jibs

A 25t-capacity free-standing jib crane is used to maintain a conveyor system that directs the flow of molten iron toward cars.

A 12.5t jib crane lifts covers on and off of slag troughs.

The cranes can reach spots that a conventional overhead crane hook could not, according to O'Brien general manager Wayne Davis.

The contract was actually won by O'Brien's Merrillville, Indiana dealer T&M Equipment. T&M also supplied JD Neuhaus pneumatic hoists for the cranes. The jib cranes and hoists are all powered by compressed nitrogen gas.
