1. Wide application range of strong tamping construction:When there's no
attachments used, the tamping capacity can reach up to 800 t.m to meet
the requirement of most strong tamping construction. The tamping
capacity can reach up to 1800 t.m when gantry is used.
2. Excellent performance of power unit: The 294kW Cummins diesel engine
with "GB Ⅱ" emission has strong power as well as reliable, economical
and environmental performance; the 120 kW variable main pump with high
transmission efficiency.
3. High strength, high reliability and good stability of chassis: The
retractable chassis mechanism hoisted by the 70 t grade creeper has an
extendable folding bracket. When working, the creeper length will be8010
mm, and the width can reach up to6250mm, medium diameter of slewing
bearing adopted is 2150 mm, and with a high strength and excellent
overall stability; the built-in planet gear reducer and large torque
running motor has a large driving force, strong grade ability and high
reliability regardless of external influence. The ground clearance of
chassis is larger than 426 mm, and grounding pressure is only 0.085 MPa
to facilitate a strong passing capacity.
4. High strength of boom:The boom formed by welding of high strength
structural pipe has a main chord pipe specification of φ114X8, and has
good rigidness, light weight and strong carrying capacity. The upper
section of boom has a projected "Goose head" structure which is more
applicable for strong tamping construction; the ratchet can lock the
derricking winch mechanism to further ensure a safe and reliable
positioning of boom.
5. Large pulling force of single rope of lifting winch:For the lifting
winch with free hook falling function and M7 working level, the maximum
pulling force of single rope can reach up to 15–20 t, and maximum rope
speed can reach up to 52m/min. The built-in normally closed brake can
ensure a reliable braking of tamper.
6. Convenient and agile operation:The hydraulic control system adopts
armrest box type pilot handle control and load sensor with micro-motion
function which is convenient and agile; the swing mechanism has
controllable free slipping mechanism to facilitate a stable operation
without impact.
7. Working with long time and large power:The hydraulic system is
equipped with an independent cooling system to ensure the engine and
hydraulic system can work for a long time with large power not resulting
in over-temperature. The useful volume for the enlarged fuel tank can
up to 800 L to efficiently guarantee a day's working.
8. High safety:It is provided with electronic combination instrument,
integrated control device of engine data, and automatic warning device;
it is also equipped with safety devices such as rotary table swing
locking device, boom anti-overturn device, winch over-rolling protection
device, lifting ultimate micro-motion device etc to make sure safe and
reliable working.
9. Comfortable operation:The shock absorbing connected cab has a wide
range of view and beautiful appearance, and is equipped with a guard
screen. The human-oriented design inside the cab such as shock absorbing
seat, fan, heater and optional MP3 audio player can provide a
comfortable operation and good working environment.
10. Convenient transportation:The external dimension for the main
machine is 9830 X 3,400 X 3,400 mm. When transporting, only the boom and
balancing weight is necessary to be removed instead of disassembly of
the whole machine, and the maximum weight for a single piece is 36.5 t
to facilitate a low transportation cost. The supported type balancing
weight with the maximum single piece weight of 6.2 t is more convenient
for the installation, disassembe and transfer.
