The new Demag PC 3800-1 pedestal crane provides access to jobsites previously unreachable with a standard crawler crane model. The PC 3800-1 boasts strong load charts, especially with main boom-only configurations. It helps reduce ground preparation and is easy to transport.
The PC 3800-1 can significantly reduce the amount of time needed to prepare a jobsite for crane operation. Typically crawler cranes require an adequately level supporting ground over a large area (slope of 0 to 0.3 degrees), which leads to extensive ground preparation prior to the lift. In contrast, the PC 3800-1 only needs four areas to be prepared for the outrigger supports, and they do not need to be perfectly leveled because the outrigger cylinders can compensate some tolerance on the ground’s flatness — up to 2.1 degrees with a 39.4- x 39.4-foot outrigger base. On top of this, existing pile foundations can be used as outrigger supports for the pedestal crane when providing sufficient stability. This setup makes the PC 3800-1 especially beneficial on jobsites where the ground layout and structure are pre-existing, like on harbor quays and refineries and when installing bridges from river banks.
The new pedestal crane features hydraulic extendable and foldable outriggers that can be positioned at 39.4 x 39.4 feet, 46 x 46 feet with all configurations including Superlift, and 62.5 x 62.5 feet without Superlift. It offers additional possibilities for long-reach lifts where the lifting capacity of a crawler crane would normally be limited. The PC 3800-1 also provides increased lifting performance in several configurations or requires less counterweight for the same or slightly higher lifting capacities. Less counterweight means fewer trucks, translating into reduced transportation costs.
For additional versatility, Demag has also developed an adapter to connect the carbody of the crane to a self-propelled modular transport (SPMT). These transporters are commonly found on jobs involving lifting bridge sections, gantries or wind turbine assemblies , which means that the pedestal crane can be easily relocated on a jobsite partially rigged, while leveraging the use of SPMTs.
Depending on road regulations, the Demag PC 3800-1 equipped with axle lines can be adapted easily to match a 12t load per axle or to have a cross vehicle weight below 100t. This can be done with many axle lines from multiple manufacturers. All a customer would need are axle lines with matching adapters between the carbody (center pot) and axle lines.
Other optional accessories for the Demag PC 3800-1 pedestal crane include a quick connection to un-deck the superstructure from the chassis and different sizes of outrigger mats.
The PC 3800-1 can be purchased as a complete crane, or the carrier only can be purchased as a retrofit option for the Demag CC 3800-1 crawler crane and its predecessor, Superlift 3800. The Quick Connection system allows efficient switching between crawlers and pedestal carrier on Demag CC 3800-1 cranes with or without the Superlift and is compatible with wind turbine combinations, as well as Boom Booster kits.
