CRH 5000 Impact Hammer

The Dawson hydraulic impact hammers available for rent from Foundiz are specially designed for driving piles in combination with a crane or foundation machine. These impact hammers can be used to drive piles and sheet piles into the ground. The impact hammers are ideal for driving steel pipes, steel sections, and steel sheet piles. In addition to free-suspension use in combination with a crane, the impact hammers can also be used in combination with a foundation rig. If the machine has sufficient pulling capacity, these impact hammers can also be used to drive vibro piles formed in the ground. Furthermore, these Dawson hydraulic impact hammers are exceptionally well-suited for underwater pile driving, where water depths of up to 100 meters—and even deeper—can be achieved.
