HHK A Series

The HHK A series is a new generation of hydraulic impact hammers with an adjustable stroke of up to 1.2 metres. The efficiency of the HHK A hammer is up to 20% more than that of a traditional free fall hammer of the same weight. The hammer is suitable for driving all types of piles including:

• Precast concrete
• Steel tube
• Sheet piles
• Timber piles

The design of the hammer frame and drive cap makes for low impact noise and less vibration while piling. All impact energy is concentrated in the centre of the pile. The construction of the hammer makes it possible to use biodegradable hydraulic oils. The hammer is easy to connect to different hydraulic systems. It can be operated by the hydraulic system of the rig or by a separate power pack. The hammer can be mounted on all kinds of leaders, or can be freely suspended.
