Unit Crane & Shovel Corporation of New Berlin, Wisc. has a brochure available describing a variety of pedestal-mounted Unit Mariner cranes that offer economical, dependable solutions to most marine handling problems, including offshore oil platforms, drilling vessels, workboats, supply vessels, dredges, and barges, as well as dockside cargo handling. Sales and service of Unit Mariners to the offshore industry are handled by Offshore Crane & Equipment, Inc. of Houston and New Orleans.
Every Unit Mariner crane, hydraulic or mechanical, is designed to meet API standards; several meet or exceed ABS specifications. All are available with diesel or electric prime movers. Load capabilities range from 5 to more than 65 tons—a range to fit the greatest number of jobs — with emphasis on big lifting capacities at long radii.
The model 650-H is the heavyweight of Unit Mariner offshore cranes. It has a lift capacity of more than 65 tons, a reach up to 150 feet, and spooling capacity of more than 1,760 feet. The 40-foot-tall A-frame design provides the capability for larger and exceptionally useful lift capacities at extended boom radii. For positive environmental protection, all structural members are blasted to bare metal, then covered with a three-coat anti-corrosion system.
The hydraulic Unit Mariner 150-H, with trim dimensions, can be mounted where many other cranes could not fit. The separate power package can be placed anywhere up to 50 feet from the crane, and can serve two cranes. The 150-H has a nominal lift capacity of 15 tons, and exceptional capacity at long radii.
