It's a new challenge and a technical feat that the Mammoet Group has just achieved on the Iter site. Not simply to move a heavy load weighing 350 tonnes, a routine task for this specialist in heavy handling and transport, but to carry out this operation using SPMT modules connected to an electric power pack. A world first, at the request of Iter and its logistics provider Daher, with a trailer configured in 2×10 lines of Scheuerle SPMTs. This first operation involved transferring a TF Coil, a toroidal field magnet, from the Assembly Hall to a storage warehouse a few hundred meters away.
On this unusual site, the various components weighing several hundred tonnes were traditionally handled by SPMTs with diesel engines. Although gases were filtered and evacuated during indoor operations, as in the Tokamak assembly building, Iter and Daher were looking for a new electrical solution. The development of this new equipment by Mammoet's "Innovation & Sustainability" department made it possible to meet this demand, and transformed a diesel power pack (PPU) into an electric power pack with battery, an e.PPU.
Identical technical specifications
Weighing in at 7.7 tonnes, it has exactly the same dimensions and features as its combustion-powered equivalent: it can tow up to 40 trailer lines, and works silently and without polluting emissions. It can be charged (in just a few hours) from a 16A, 32A or 64A three-phase socket, and has an average operating consumption of 40kW, with a battery capacity of 194 kWh. A start/stop function avoids idling between two activities, thus saving battery power. Autonomy is sufficient for two days of standard on-site operation.
So far the only one of its kind, this first e.PPU could be followed by others, given the numerous requests from other Mammoet customers.
