Dock manoeuvres for Terex hammerheads
By Euan Youdale10 August 2011
Detyens Shipyards is operating two Terex SK 415 hammerhead tower cranes at its site in Charleston, South Carolina, USA.
The company specialises in the repair, refurbishment and conversion of government-owned and commercial vessels
Configured with a 197 foot (179 m) jib and 150 (136) and 189 foot (171 m) under hook heights, the cranes are placed strategically to serve the pier for alongside repairs and two dry docks. Their main duty is placing supplies and equipment.
The cranes have proved to be quick and economical, said Loy Stewart, president of Detyens Shipyards, "Our gantry cranes are diesel-electric and burn a considerable amount of fuel. The SK 415s are electric which makes them a lot cheaper to operate."
From dredgers and barges, to container carriers, tankers and cruise ships, the size of vessels has steadily increased as the worldwide shipping industry grows, Stewart explained.
"The height, capacity and reach of our Terex SK 415 cranes allow us to reach the ships' extremes while enabling our operators to see exactly what they are doing, which is paramount to efficiency and safety."
The three models in the Terex SK series offer jib lengths from 40 to 80 m for maximum load capacities from 16 to 32 tonnes. Freestanding heights extend to 75.8 m, and the series is fully compatible with Terex CTT and CTL tower Cranes.
