Good good good vibrations

Cement, water, sand, and gravel of different grain sizes: That’s the stuff that concrete is made of. When the material is poured into the mould, its consistency determines how well it is distributed. It also tends to form an air-filled cavity or two. And the result is poorly compacted concrete parts with unclean surfaces. The solution is a bout of good and proper vibrations, preferably with high-frequency technology. The vibrations force the air out of the viscous mass, the components are compacted and the concrete can set neatly.

Weckenmann’s high-frequency vibration station with magnetic clamping has refined the technology of concrete compaction. The substructure of the shuttering pallets is fitted with optimally positioned vibration steel plates. Attached to these plates then are freely suspended, strong vibration-proof electromagnets of the vibration units that can be raised and lowered. The vibrators work with a directed vertical amplitude and an infinitely adjustable speed from 0 to 6,000 r.p.m. depending on the particular requirements to the concrete and the final product.

The advantage of this technology is the significant reduction in energy consumption and noise level. Due to the fact that the vibrators are directly connected to the mould, the energy is directly transferred into the pallet. Another advantage is that the heavy vibration blocks fall away in this process. This means that less material is moving, so less energy needs to be used. Plus, all this makes much less noise. All for the sake of environmental protection and occupational safety.
