To meet the demand, the Pyongyang Construction Machinery Factory produced new kinds of efficient vibrating compactors, motor scaffold and plaster mixer which save much labor and concrete mixture.

One of those vibrating compactors is the single-phase one which is easy to use, irrespective of the size and place of construction objects.

What draws attention is that the new vibrating compactors are small, but strong in vibration when compacting concrete mixture, so as to raise the speed and quality in building frameworks like floor slab and wall.

In particular, the electronic vibrating compactor without electric motor is expected to be effective in building skyscrapers.

All the new vibrating compactors are much lighter than existing ones.
