HYDRAULIC IMPACT HAMMERS
DAWSON's double-acting hydraulic impact hammers are designed to develop high speed, delivering maximum energy at 80 strokes per minute, ultimately providing better production rates and yields. They can be used to drive a wide variety of sheet pile sections, steel beams or pipes, as well as concrete piles. Offering excellent driveability to improve performance, make it safe and minimize any damage to the pile.
DAWSON has developed an industry-leading, robust and simple electronic control system that constantly monitors the position of the piston weight. This constant monitoring allows the hydraulic main piston to be changed in a timely manner when variations in ground conditions occur.
The breakers can be used with excavator or pendant and can be submerged up to 100 meters, with models ranging from 5,000 to 60,000 kgm, with diesel or electric power source options.
