IMPACT Hammer 800 series

IMPACT Piling hammer 800 series

With a frame diameter of 863mm and a ram weight range of 7Mt up to 12Mt the 800 series hammer is very suitable for the heavy piling jobs. Jobs with square piles 45×45 but also tubes with a diameter of 813mm. With the special sheet legs it is possible to drive sheet piles.

Due to the combination of ram weight and diameter the IMPACT 800 series is shorter than any assisted hammer available in the market.

For the 10Mt and 12Mt Dematec designed a 1.500mm stroke cylinder for driving steel tubes and beams. All hammers in the 800 series can be used as free hanging device or leader mounted.

Within the 800 series the hydraulic system is equal. Therefore up grading to a heavier ram weight is without any problems. Only add a ram weight and extend the frame and increase the hydraulic pressure. That is what we call flexibility!

  • E pot = POTENTIAL ENERGY = M * G * H Example: IMPACT 3S40 hammer E pot = 3 (ton) * 9.81 (m/s²) * 1.2 (m) = 35.3 kNm

    E kin = KINETIC ENERGY= 1/2 MV² Example: IMPACT 3S40 hammer E kin = 3 (ton) * 4.85 m/s * 4.85 m/s = 35.28 kNm

    (V = max drop speed at max stroke ram weight) V is measured by sensors and measures actual speed.

    Efficiency IMPACT HAMMERS ACCELARATED: E pot / E kin = 99 % – 4 % absorbtion by cushion pad = 95%
