to drive steel elements and wooden or reinforced concrete
piles. It is power by hydraulic system build on excavator or
pile driver.
Working based on: free falling of the ram and hydraulic raise. Hammer
type HY-ram is supplied with electronic control system, which
include height of falling and hitting frequency.
The hammer construction provided the best energy transmission into
pile. HY-ram hammers are produced in a few versions, weight
from 250 to 2750 kg. They interact with a special pole build on
