Transcript

  • 1. Hydraulic Hammers
  • 2. Advantages of Junttan hydraulic hammer <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><ul><li>Environmentally friendly compared to diesel hammers </li></ul>
  • 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. <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. Hammer utilisation Purpose built piling rig (hammers up to 12 ton) Crane use with hanging leader (normally hammers from 14 ton and up)
  • 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. 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>
  • 8. 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. <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. 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. Junttan Hammer general arrangement
  • 12. Easy and safe to use Control Box Stroke height scale on hammer frame Energy measure device (Optional) Power Pack
  • 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. 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. 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. 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. 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>
  • 18.
