Trench rammer hire in Cork, often called a jumping jack. Carey Tool Hire stocks a jumping jack and a DYNAPAC LT604 petrol trench rammer. A rammer hits straight down, so it compacts narrow trenches a plate cannot reach. Backfilling a service trench? The rammer is the right machine. Open ground instead? Take a wacker plate or a vibrating roller. Day and week rental rates, delivery across Cork. Call to check availability.
