  3. 3. Three piling hammer technologies <ul><li>Hydraulic hammers </li></ul><ul><li>Diesel hammers </li></ul><ul><li>Air/steam hammers </li></ul>
  4. 4. <ul><li>HHK A - series: Stroke up to 1200 mm </li></ul><ul><li>HHK S – series: Stroke up to 1500 mm </li></ul><ul><li>Ram weight from 3 to 25 tons </li></ul><ul><li>Energy output from 35 to 368 kNm </li></ul>Junttan Hammer models
  5. 5. Hammer utilisation Purpose built piling rig (hammers up to 12 ton) Crane use with hanging leader (normally hammers from 14 ton and up)
  6. 6. Hammer utilisation Barge use with fixed leader (normally hammers from 16 ton and up) Crane use with flying leader (normally hammers from 14 ton and up)
  7. 7. Junttan Hammer Structure <ul><li>Effective energy transfer </li></ul><ul><li>Proven, simple and robust design </li></ul><ul><li>Versatile options </li></ul><ul><li>Easy to use and maintain </li></ul>

Junttan Hammer Attachments <ul><li>Lifting Kit for Crane Hanging application </li></ul><ul><li>Includes </li></ul><ul><ul><li>Cylinder Top protection </li></ul></ul><ul><ul><li>Lifting sling </li></ul></ul><ul><ul><li>Ropes </li></ul></ul><ul><li>Raked piles Kit </li></ul><ul><ul><li>Long ropes </li></ul></ul>
  9. 9. <ul><li>Flying Leader Kit for Crane hanging application </li></ul><ul><li>Needed for raked piles in higher inclination </li></ul><ul><li>Feaster and easier work with raked piles </li></ul>Junttan Hammer Attachments
  10. 10. Junttan Hammer Attachments <ul><li>Fixed Leader application </li></ul><ul><ul><li>Piling Barges </li></ul></ul><ul><ul><li>Large Piling Cranes </li></ul></ul><ul><li>Guide claws available for different leader profiles </li></ul>
  11. 11. Junttan Hammer general arrangement
  12. 12. Easy and safe to use Control Box Stroke height scale on hammer frame Energy measure device (Optional) Power Pack
  13. 13. Easy to set up and service <ul><li>Quick set up for operation </li></ul><ul><li>Easy to handle </li></ul><ul><li>Easy access to the service and repair points (seals, cylinder) </li></ul>
  14. 14. Diesel hammers (single acting) <ul><li>Self contained unit, does not require additional equipment </li></ul><ul><li>Increase strokes in hard driving provide increasing energies, low strokes in easy driving protect concrete piles </li></ul><ul><li>Relatively low ram weight compare to energy (high strokes) </li></ul><ul><li>Stroke dependent on hammer-pile-soil system, the stroke can not be effectively adjusted by operator. </li></ul><ul><li>Relatively low blow rates ( blows per minute) with high strokes </li></ul><ul><li>Environmental problems (smoke, noise, vibration) </li></ul><ul><li>Very complicated on off shore </li></ul>
  15. 15. The advantage of Hydraulic hammers <ul><li>The impacting energy is adjustable with adjusting the drop height </li></ul><ul><li>The time of impacting is adjustable thanks to driving is independent on the Hammer-pile-soil system </li></ul><ul><li>Higher efficiency </li></ul><ul><li>No smoke and oil pollution from hammer </li></ul><ul><li>Lower noise level </li></ul><ul><li>Lower impacting vibration </li></ul><ul><li>Bigger inclination can be reached with less energy loss. </li></ul><ul><li>Better penetration, more meters/hour </li></ul><ul><li>Same hammer can be used to drive all of the material piles and all kind profiles </li></ul>
  16. 16. JUNTTAN hydraulic hammer offers <ul><li>Simplicity compare with other hydraulic hammer </li></ul><ul><li>The stroke is designed to be suitable to both steel piles and concrete piles. </li></ul><ul><li>Suitable to bigger Inclination with minimum energy loss </li></ul><ul><li>Suitable to both on shore or off shore without any extra cage (free suspended driving) </li></ul><ul><li>With driving cage the hammer can reach bigger inclination on concrete pile (does not bend the pile) </li></ul><ul><li>The cage design could be very simple thanks to the less weight of the hammer, the bigger crane capacity is not needed. </li></ul><ul><li>Perfect energy transfer from hammer ram to pile, more meters/hour </li></ul>
  17. 17. JUNTTAN Hydraulic Hammer Offers <ul><li>Easy to operate </li></ul><ul><li>Hydraulic and electronic control system </li></ul><ul><li>Free fall hammer </li></ul><ul><ul><li>The downward force is to overcome the loses in the system </li></ul></ul><ul><ul><li>To drive the concrete pile with easy drive </li></ul></ul><ul><li>The ram block weight can be easily modified into different weight. </li></ul><ul><ul><li>The hammer can be performed as several hammers </li></ul></ul><ul><li>The hammer stroke could be controlled and adjusted by operator with figure tip movement, so that the hammer could be used in the most difficult soil conditions. </li></ul><ul><li>Extra meters could be driven </li></ul><ul><li>Longer lift time, easy service </li></ul>
