Specialties ( Improved Points );-
1) By utilizing the Accelerated Drop System (Double Action System), a big impact energy
can be generated even at a short falling height (Stroke), compared with the other Free Falling
System. Therefore shortening of the Ram Stroke became possible, consequently it enabled
all hammering works by the Leader with a short length.
2) By using the Sensor System, it is possible to control Ram Falling Height precisely.
This Sensor System made reduction of the Unbalance of each Impact Energy, compared
with the conventional Timer System. Our new product has a revised & improved design
with 7(seven) ea of Sensors built-in internally, enabling 8 (eight) steps controls of Ram Stroke.
3) With adopting the Logic Valve, circuit loss of the hydrulic oil is reduced, the hammer operates
under low fuel consumption rate. And the shock absorbing function of the hydraulic oil circuit
enables decrease of jumping of the hydraulic oil hose. And endurance life time of the hose,
cable, etc. has been increased.
4) Number of blow (rate) is increased and Input Rate of the pile per one blow became bigger,
thus operating speed has been much faster.
5) For the impact blowing areas, the special sound-proof materials have been used, enabling
minimization of noise generation, thererfore resulted in environment protection.
6) The cushion wear-rate indicator is adopted and so, it became possible to confirm
the cushion wear-condition even from the operation room. If wear rate is over 30mm,
the hammer gives alarm to the operator.
7) An auxiliary cooling pump is used separately in order to cool down generated heat thoroughly.
Hence, the hammer can be used for a long time without trouble even at the Tropic Zones.
8) The Ram design has been improved into One Body System (solid), from the conventional stud bolt
assembly system. Therefore the former problems of loosening & breakage of built-in stud bolts
are solved out, thus a long time maintenance cost for overhaul, repair & re-assemble is saved.
9) The conventional complicated hydraulic circuit has been newly designed into a simplified &
improved hydraulic circuit, so, an easy maintenance is possible during the trouble shooting. |
