Junttan Hydraulic Impact Hammers
As a pioneer in the field of hydraulic piling hammers, Junttan has developed a new generation of hydraulic impact hammers that offer up to 20% more efficiency than that of a traditional free-fall hammer of the same weight.
Junttan hydraulic impact hammers are suitable for driving steel tube pipes, steel sheet piles, precast concrete and timber piles. The stroke and blow rates are adjustable to optimize the pile driving performance in all conditions while the ram weight can also be charged to accommodate different pile type requirements. Due to this, one hammer can efficiently serve a wide range of different pile driving operations. The impact hammers can be mounted on all kinds of leader or freely suspended.
A Junttan hydraulic impact hammer is also friendly to the environment as they generate less noise, vibration and emissions than many other options.
- Perfect energy transfer to pile
- Smoothly adjustable hammer impact stroke.
- Smoothly adjustable impact frequency
- Suitable for different kinds of leaders or freely suspended
- Easy to connect to different hydraulic system
- Modular ram block design
- Easy to operate and maintain
- Low cost of operation
The HHK S-series is a new generation of hydraulic impact hammer with an adjustable stroke of up to 4.9 ft (1.5 m). The efficiency of the HHK S-hammer is up to 20% more than that of a traditional free-fall hammer of the same weight. It is suitable for driving all types of piles including precast concrete, steel tube, sheet and timber piles.
The design of the hammer frame and drive cap makes for low impact noise and less vibration while piling as all impact energy is concentrated in the center of the pile. The construction of the hammer also makes it possible to use biodegradable hydraulic oils and 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 and mounted on all kinds of leaders or freely suspended.
