Description

The concrete plant is intended for producing concrete mixtures, building mortars, and their discharge into an auto mixer. It can be operated in an enclosed space or under a shelter at surrounding temperatures between +5ºС and +45ºС. The area or the shelter must be at least 9 meters high. The area for installing the concrete plant is required to be equipped with the three-phase current mains with the grounded neutral and it must have a load-carrying device (holding capacity over 10 ton) for assembling, maintaining and repairing.
