Protea Launches Heavy-Lift Cranes

Protea, a manufacturer of offshore handling equipment, launched two types of heavy lift cranes at Nor-Shipping in Oslo earlier this year.
“The target of any marine crane design is to provide high lifting performance whilst minimizing overall weight,” said Tomasz Paszkiewicz, Protea’s CEO. “Over the past three years we have been developing the technology and construction methodology to allow a step change in the structural efficiency of heavy lift cranes.”
“We are now able to deliver high performance heavy lift cranes that comply with the relevant Class requirements but with a weight saving in the order of 40 percent in comparison to existing cranes of a similar capacity.”
The two new crane types are the latest additions to the Proteus crane family.
The first is a 1,600mT SWL floating crane targeted at the offshore wind market for the installation of offshore wind turbines. It provides a high capacity lifting capability at both short and long outreaches over a large radius, a key feature for offshore wind farm operations.
The second is a 450mT SWL versatile cargo lift crane that can be used for handling both shipping containers and bulky items of hardware. Typically supplied as a working pair and designed to allow safe tandem lifts, the saving in crane weight translates directly to an increase in cargo capacity for the cargo vessel.
Both cranes can be supplied with a fully electric drive system with locally mounted permanent magnet synchronous motors to provide efficient and precise operation of all crane functions.
