Lockheed - Fort Worth, Texas
Joint Strike Fighter  /  Burns & McDonnell

Our Dallas office landed the bulk of the materials handling machinery and runways for Plant Improvements for the new Joint Strike Fighter. Burns and McDonnell selected PHD to design and provide state of the art cranes, runways, and hoisting equipment for Earths Latest - Greatest Machine assembly and production as well as the new streamlined F-16 Final Assembly. For national security reasons, we can’t show pictures, but we did receive permission to say this much. See ACAD artists perspective.

PHD combined the latest high tech girder designs and created a new patented track section to fit and conform to WWII vintage 4” flange rails. The result was reduced dead weight on the old building and trusses to the degree that we saved the customer hundreds of thousands in dollars. The Super Span Light Box had less deflection even when spanning twice as far as the old cranes. Still considered under-running and patented track – 4 inch tread, the cranes interlocked with the old and new sections of the building and rail systems. Exactly one half of the rail and related expenses were avoided with the greater spans of the box (with lower truss point loadings).

Box-to-Box Interlocking features where cranes could be mated into one 200’ span bridge and driven as one bridge, we also provided Demag’s Micro-Drive Hoist motor controls designed for continuous full load lifting at the precise speed of 1.5 FPM over the full 50 feet of travel. We also provided the Load Halt feature that NASA approved for safe lifting, which is basically a secondary brake applied to the rope drum, which is outside the hoist’s gear train, motor, and motor brake. In other words, the motor, brake and/or gearbox could completely fail and come loose, and the load will not fall. 

Future Pipe Industries -  Gulf Port,  Mississippi  
‘Get More And Pay Less’

PHD was awarded the contract for this new pipe manufacturing plants cranes and runways. TURNKEY DESIGN of the runways along with the cranes, rail, and electrical allowed the customer to SAVE MONEY and get the more expensive, high performance cranes.

Our cranes with automatic, continuous, sub-arc welded box girders and Demag hoists were the most expensive crane option. Large span cranes at 77’ rail centers, with process duty ratings at 16 ton capacity and several at 5 ton capacities, were to run on long 600’ runways. We demonstrated the affect of our reduced dead weight by offering an option for runway beams TURNKEY. The result, with steel costs so high, a realized savings much greater than the price difference for the cheaper crane quotes.  F.P. got the Demag hoists they wanted ( that cost quite a bit more ) ; but also, saved thousands due to the total package.

How To Build A Better Crane

These cranes featured PHD ‘mill-master’ end trucks for this heavy service, process application. Trucks use hardened wheels on rotating axles mounted in traditional corner bearing fashion. Torque arm mounted hollow shaft box with helical gearing combined with Power Electronics’ variable frequency drives assure years of heavy service and minimum maintenance. Then use PHD’s mono-box design for light- weight and l/ 800 deflection criteria, and place (2)  Demag DH 425 hoists with independent and simultaneous controls to not only solve this 16 ton process-duty crane’s application, but make it bullet-proof.

Amarillo Symphony Hall - Amarillo, Texas
Hunt Construction

PHD is providing new technology to the symphony and theater industry with product first (100,000 pound capacity crane structure) that holds and transports the entire orchestra lamella with acoustical walls and ceiling. This turtle-shell looking sound-cone envelopes the performers with the audience, positions the shell for perfect sound, and stores the shell back into a parking garage to facilitate stage and instrument set up and teardown. The walls and shell hang inches above the floor and have caged ladders and catwalks throughout for lighting, rigging, and sprinkler systems.

PHD provided not only the crane, with high tech box girder design, and a feather smooth drives package, but also the walls and ceiling, the wall and lamella infra-structure, cat-walks and ladders, and even the velvet covered shelves for musician gear and instruments.

Gulf Marine Fabricators  -  A Technip Company    

This established customer of our Houston Division came across a “used” crane package. They were at the time a subsidiary of Peter Kiewit Company. They bought and installed several of these very large cranes ( most 50 ton capacity and some 100 ton capacity). These new-used cranes did not hold up well next to the aging Demag cranes that PHD had sold and installed back in the early 1980’s. They suffered (maintenance and parts costs) with these for almost 6 years. One by one, PHD’s Houston Service arm replaced hoists and trolleys, and then also the drives and controls. The old cranes now were faster, smoother, and with modern components. PHD also accomplished this modernization project, below the quoted costs that the “used” original crane manufacturer had priced to rebuild and to up-grade on their own brand of equipment.

Jerry Forest with Gulf Marine allows us to quote him the following year, now 2005. “ Our Pipe Mill annual maintenance costs, including equipment asset allocation vs depreciation, has been reduced by 75%, thanks largely in part to PHD service and the Demag DH hoist.”

Gulf Marine has extended outsource Preventative Maintenance contracts to our Houston group, and has on order yet another batch of cranes and hoist components with install.
