We are currently in the market for a pile hammer specifically designed to drive precast concrete piles into sandy soil, particularly in lagoon environments. The piles we are working with measure 450mm square and weigh between 5 to 6 metric tons, and we need the hammer to effectively reach depths of 12 to 15 meters. We're looking for a reliable solution that can handle the unique challenges of lagoon conditions while ensuring optimal efficiency. Please share your recommendations, product specifications, and any relevant information regarding performance capabilities and pricing. Your insight will be invaluable to our decision-making process.
