Top of the CDH fleet. Engineered heavy lift for refinery vessels, LNG modules, and critical structural picks.
The 500-ton class is the heaviest crane we field, and it gets dispatched only with an engineered lift plan, pre-construction meeting, route survey, and dedicated lift director. Used for refinery vessel sets, LNG and petrochem module work, major structural picks, and any lift that is too critical to fail. Counterweight, mat plan, and rigging are sized to the specific pick.
| Max capacity | 500 tons (1,000,000 lb) |
|---|---|
| Main boom | Up to 305 ft telescopic |
| Max tip height | ~450 ft with jib / Super Lift |
| Configuration | Multi-axle hydraulic, Super Lift available |
| Transport | Multi-truck convoy, route engineering, mat staging |
| Operator | NCCCO certified, dedicated lift director, signal team |
Cranes rotate between yards as the work demands. Call dispatch to confirm availability for your date.
Engineered heavy lift execution for refinery, petrochem, LNG, marine, and major structural picks across the Gulf South.
In-house lift plan engineering for critical picks. Load chart verification, rigging design, route survey, and pre-construction coordination.
Pre-staged cranes, pre-badged operators, and 24/7 dispatch for refinery and petrochemical turnarounds in the Gulf South.
500 tons (1,000,000 lb) is the chart maximum, and that figure applies only at minimum radius with full counterweight. Real capacity falls sharply as the boom extends and the load moves away from the crane. A 500-ton rating routinely means a working capacity in the single-digit tons at long radius, which is why we size from your weight and reach rather than from the headline number.
Main boom is Up to 305 ft telescopic, and maximum tip height is ~450 ft with jib / Super Lift. Height and capacity trade against each other, so the useful question is how much weight you need at what height, not how high the boom goes empty.
Lafayette, Lake Charles and Baytown. If the nearest yard has its unit committed we will quote from the next closest rather than leave you waiting, and the mobilisation difference is shown in the quote.
Refinery reactor and vessel sets, LNG module sets, Petrochem coker and cracker turnaround, Major bridge member placement, among others. It is the class we reach for when those jobs come up, though the deciding factor is always the specific weight and radius.
The footprint is set by the outrigger spread, not the carrier, and for a 500-ton class unit that is substantially larger than the machine looks on the road. Ground bearing matters as much as area: this class concentrates enough load through each outrigger to need mats on anything but engineered hardstanding. Send a photograph of the setup area and we will confirm before the day.
Multi-truck convoy, route engineering, mat staging. Counterweight and sometimes boom sections travel separately, so allow assembly time on site in addition to the pick itself.
Operated rental is the default and includes an NCCCO-certified operator, fuel and insurance while the crane is under our control. Bare rental is available to contractors carrying their own certified operators and equipment coverage.
Weeks, realistically. Units this size need route survey, permits and often ground preparation, and there are fewer of them in the region, so lead time is the constraint rather than the crane.
Slings, shackles, spreader bars, man baskets and matting are all available alongside the crane and are quoted with the pick rather than bolted on afterwards. Operated rentals include the rigging our operator needs to make the lift.
Then we say so before the day. Under-sizing is dangerous and over-sizing is expensive, so dispatch would rather spend two minutes on your weight and radius and quote a different class than send a crane that cannot make the pick.
Two-minute call and we can quote a date, a rate, and a yard.
