A Terex brand, Demag offers PC 3800-1 pedestal crane with extended lifting performance possibilities at job sites that were previously hard to reach.
Team CV
Terex has introduced a new Demag pedestal crane called the PC 3800-1. It offers extended lifting performance possibilities, and provides access to job sites previously not reachable with a standard crawler model. Boasting strong load charts, especially with main boom only configurations, the PC 3800-1 helps to reduce ground preparation. Easy to transport, the crane significantly reduces the amount of time needed to prepare a jobsite for an operation. Typically crawler cranes require an adequately levelled supporting ground (slope of 0 degree to 0.3 degree) over a large area to achieve the nominal lifting capacity. This calls for extensive ground preparation prior to the lift job. The PC 3800-1, in contrast, needs four spots to be prepared for the outrigger supports. The outrigger supports do not need to be perfectly levelled as the outrigger cylinders can compensate tolerance on the ground’s flatness by up to 2.1 degree with a 12 x 12 m (39.4 x 39.4 ft.) outrigger base.
With the possibility of using existing pile foundations on the top of the outrigger base as outrigger supports for the PC 3800-1 to provide sufficient stability, the versatility of the Demag pedestal crane makes it beneficial in terms of usage and ground preparation. Beneficial on jobsites where ground layout and structure are already existing, which is often the case on harbour quays and refineries, as well as when installing bridges from river banks, the PC 3800-1 pedestal, with its hydraulic extendable and foldable outriggers, that can be positioned at 12 x 12 m (39.4 x 39.4 ft), and 14 x 14 m (46 x 46 ft) with all configurations including Superlift and 16 x 16 m (62.5 x 62.5ft) without super lift.
Making for additional long-reach possibilities where the lifting capacity of a crawler crane would normally be limited, the PC 3800-1 pedestal crane also provides increased lifting performance in several configurations. It 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 12-tonne load per axle, or to have a cross vehicle weight below 100-tonne. This can be done with many axle lines from multiple manufacturers.
