Terex introduces new Demag pedestal crane

PC 3800-1 provides versatility and greater access to job sites out of reach of standard crawlers

Terex Cranes has expanded its Demag mobile crane line-up with the new PC 3800-1 Pedestal Crane, which improves access to job sites previously not reachable with a standard crawler model.

According to a statement from Terex, the PC 3800-1 boasts strong load charts, especially with main boom only configurations, is easy to transport and also helps in reducing ground preparation. Applying the PC 3800-1 can significantly reduce the amount of time needed to prepare a jobsite for crane operation, it added.

Typically, crawler cranes require an adequately-levelled supporting ground with slopes of less than 0.3 degrees over a large area to achieve the nominal lifting capacity, requiring extensive ground preparation prior to the lift job. In contrast, says Terex, the PC 3800-1 only needs four spots to be prepared for the outrigger supports which do not need to be perfectly levelled as the outrigger cylinders can compensate for up to 2.1 degrees of unevenness with a 12x12m outrigger base.

Existing pile foundations can also be used as outrigger supports for the PC 3800-1, Terex added, which makes it especially beneficial on job sites at harbour 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 12x12m, 14x14m with all configurations including Superlift and 16x16m without Superlift. It also offers additional possibilities for long-reach lifts where the lifting capacity of a crawler crane would normally be limited. The crane also provides increased lifting performance in several configurations or requires less counterweight for the same or slightly higher lifting capacities, said Terex.

Less counterweight means fewer trucks, translating into reduced transportation costs.

Demag has also developed an adapter to connect the center pot of the crane to a Self-Propelled Modular Trailer or axle line, said Terex. Axle lines are found on jobs involving lifting bridge sections, gantries or wind turbine assemblies, which enables the crane to be easily relocated on a partially rigged jobsite, while leveraging the use of axle lines. Depending on road regulations, the PC 3800-1 equipped with axle lines can be adapted to match loads of 12t per axle or to have a cross vehicle weight below 100t, said Terex.

Other optional accessories for the Demag PC 3800-1 include a quick connection to un-deck the superstructure from the chassis, and various 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. A Quick Connection system allows efficient switching between crawlers and pedestal carriers, and is compatible with wind turbine combinations as well as Boom Booster kits, Terex added.
