New Demag PC 3800-1 Pedestal Crane provides versatility
31 July 2017
The new Demag® PC 3800-1 Pedestal Crane offers extended possibilities in lifting performance and lifting abilities. It provides access to jobsites previously not reachable with a standard crawler model. The PC 3800-1 boasts strong load charts, especially with main boom only configurations, helps reducing ground preparation and is easy to transport.
Applying the PC 3800-1 can significantly reduce the amount of time needed to prepare a jobsite for crane operation. Typically crawler cranes require a adequately levelled supporting ground (slope of 0° - 0,3°) over a large area to achieve the nominal lifting capacity leading to extensive ground preparation prior to the lift job. In contrast, the PC 3800-1 only needs 4 spots to be prepared for the outrigger supports which do not need to be perfectly levelled as the outrigger cylinders can compensate some tolerance on the ground’s flatness — up to 2.1° with a 12 x 12 m (39.4 x 39.4 ft) outrigger base. On top of this, existing pile foundations can be used as outrigger supports for the PC 3800-1 when providing sufficient stability. This setup makes the PC 3800-1 especially beneficial on jobsites where ground layout and structure are already existing, which is often the case on harbor quays and refineries, as well as when installing bridges from river banks.
The new PC 3800-1 pedestal crane features hydraulic extendable and foldable outriggers that can be positioned at 12 x 12 m (39.4 x 39.4 ft), 14 x 14 m (46 x 46 ft) with all configurations including Superlift and 16 x 16 m (62.5 x 62.5ft) without superlift, and 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 significantly reduced transportation costs.
For additional versatility, Demag has also developed an adapter to connect the carbody (center pot) of the crane to a Self Propelled Modular Trailer or axle lines. Axle lines are commonly found on jobs involving lifting bridge sections, gantries or wind turbine assemblies , which means that the crane can be easily relocated on a jobsite partially rigged, while leveraging the use of axle lines.
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.
