Demag levels the playing field with uneven ground

Demag PC 3800

The new Demag PC 3800-1 Pedestal Crane is providing access to jobsites previously not reachable with a standard crawler model.

Typically, crawler cranes require an adequately levelled supporting ground over a large area to achieve the nominal lifting capacity, leading to extensive ground preparation prior to the lift job.

However, the PC 3800-1 only requires preparation of four spots for the outrigger supports, which do not need to be perfectly levelled.

The outrigger cylinders may compensate some tolerance on the ground’s flatness — up to 2.1 degrees with a 12 x 12 metre outrigger base.

As well, existing pile foundations may be used as outrigger supports, when providing sufficient stability.

The setup makes the PC 3800-1 beneficial on jobsites where ground layout and structure are already existing, which is often the case at harbour quays and refineries, as well as when installing bridges from river banks. 

The pedestal crane features hydraulic extendable and foldable outriggers, which may be positioned at 12 x 12 metres or 14 x 14 metres with all configurations.

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.

Demag developed adapter

For increased versatility, Demag developed an adapter to connect the carbody of the crane to a self-propelled modular trailer or axle lines, which are commonly found on jobs involving lifting bridge sections, gantries or wind turbine assemblies.

Moves with ease

Leveraging the use of axle lines allow easy relocation of the crane on a jobsite while partially rigged.

Furthermore, equipping the crane with axle lines allows it to be adapted to match a 12 ton load per axle, or to have a cross vehicle weight below 100 tons.

This is achievable with numerous axle lines from multiple manufacturers.

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, the Superlift 3800. The Quick Connection system allows efficient switching between crawlers and pedestal carrier on the Demag CC 3800-1 crane — with or without the Superlift — and is compatible with wind turbine combinations, as well as boom booster kits.
