National Crane Offers Free Literature On Cranes For Marine Applications

Telescoping hydraulic cranes especially designed for offshore petroleum and other marine applications are available from National Crane Corporation.

The National Marine Lifting System is comprised of the Marine 200, 400, 600A and 800B series. Together, they fill medium- to heavyduty lifting demand on ships and fishing boats, docks and offshore platforms.

Maximum capacities and hydraulic boom lengths are: Marine 200, 10,700 pounds and 28 feet; 400, 16,000 pounds and 55 feet; 600A, 25,000 pounds and 66 feet; 800B, 35,000 pounds and 75 feet (four-section boom). Full marine conditioning is standard on these models, including sand blasting, inorganic zinc primer, paint and chlorinated rubber topcoat on all external surfaces, primer and paint on internal surfaces, and stainless steel lift cylinder rods and boom pivot pins.

The National Series 666A Skid Wireline Support Unit is especially designed for the wellservice industry. The skid-mount's mobility means a larger number of wells in different locations can be serviced than ever before. After transport to platforms by truck, the unit secures to any solid base.

The 666A's three-section fully hydraulic boom telescopes sequentially to a full 66-foot extension.

Maximum capacity is 25,000 pounds.
