CONCRETE BATCH PLANT

Basic specifications and construction (Standard Equipment)

This MOBILE CONCRETE BATCH PLANT is lightweight and can be towed into very remote job sites where the roads are very tight or hilly, or if space (area) requirements are minimal. His batcher dispenses sand, rock, cement, and water by weight (lb. or kg) for accuracy and ticket-able receipts.
