tom-built, completely automated, no-operator, computer-controlled bulk material handling cranes for heavy industrial applications. This crane was designed for scale pit operations in steel mills, and for handling bulk chemicals, cryogenic waste materials, cement, and vir- tually any other heavy bulk materi- al.

The crane can be controlled from ground level, or remotely from the mill's main process computer. A ground-level microprocessor is pro- grammed for all on-board logic, and is also tied via modem to the main process computer.

The Reliable line of cranes offers these features:

Hoist bucket holding and hoist bucket closing lines are controlled by state-of-the-art, microprocessor- based, DC adjustable-voltage con- troller.

Dependable mill motors are em- ployed for hoist drives.

Travel drives are standard, re- versing-plugging, AC magnetics us- ing resolvers to position crane bridge for digging and discharge.

Field programming capability to establish multiple location, digging and discharge points for material loading and unloading.

Scoreboard-type readout to pin- point locations that have already been cleaned and those to go.

Built-in logic that prevents dig- ging at previously emptied location.

Lidgerwood Manufacturing Com- pany of New York was established in 1873 as a continuation of the

Speedwell Iron Works of Morris- town, N.J. From its standard hoist- ing equipment, Lidgerwood evolved marine winches.

These were produced extensively for steam power and later were adapted to electric applications.

Capstans, anchor windlasses, and marine winches still continue to be a source of pride to Lidgerwood, which has stood the test of time.

The company offers a full range of well-illustrated literature that de- tails the capabilities, special fea- tures, and specifications of its line of marine equipment. Included are marine equipment such as inte- grated barge moving systems; car- pullers; capstans; steam hoists; trawling winches; towing winches; mooring bits and winches; cargo winches; gasoline, diesel, or electric hoists; anchor hoists; crane, dock, hatch-cover, and dredge hoists, and windlasses. range of winches that will handle up to 21/2-inch wire rope.

Timberland has designed and manufactured powered winches for more than 25 years for the construc- tion, mining, and marine industries.

Recently they have expanded the product line to serve a wider range of winch applications for mooring, anchoring, and positioning of ser- vice vessels.

Unit Crane & Shovel Corporation of New Berlin, Wise., manufactures a series of hydraulic Unit Mariner pedestal-mounted marine cranes that meet 1983 American Petroleum

Institute specifications covering off- shore cranes.

The latest Mariner line offers lift capacities of 27,000, 36,000, and 55,000 pounds, with basic boom lengths at a 30-foot radius. Modu- lar assembly is said to provide fast assembly and easily accessible servicing. A variety of hydraulic winches is available to meet specific load capacities and line speed re- quirements.

OTIS ENGINEERING CORPORATION, a Halliburton company, recently purchased a Manitex ML-4800 to increase the lifting capabilities of its jack-up barge, the

M/V Ben Tolbert. An Otis representative explained further: "After considering several pedestal-mounted lattice boom cranes, we selected the Manitex ML-4800 because of its many advantages over competitive rigs.

We were particularly impressed with the way the 4800 could be custom-tailored to meet our exacting perfor- mance requirements. As a result of the 4800's capabili- ties, we are now able to bid a wider range of projects and complete our contracts more efficiently than ever before.'' "For example, we recently used our ML-4800 during a snubbing operation in the Gulf of Mexico. During a review of that project, our client cited our ML-4800 as being the most vital piece of equipment used ... as its high capacity and versatility contributed greatly to the project's overall success." "We're convinced Manitex SeaCranes are one of the best investments any offshore operator can make. Not only are they ruggedly constructed from marine-quality components, they exceed the requirements of leading maritime codes. Equally important, we know Manitex cranes are backed by a worldwide distributor network that provides parts and service support no matter where our projects take us."

If performance and dependability are your objectives, make no compromise... Manitex doesn't.
