Description:
SR14D-3 new generation high-frequency electronically controlled
double-drum vibratory road roller adopts the modular frame
structure and the inclined drum support, featuring prominent
quality and high efficiency. This product is applicable for the
road base layer and medium and small filling projects and is one
ideal machine for pavement of concrete roads. It can work with
spreader to sufficiently play the comprehensive advantages of
complete equipment set.
Advantage:
1.The imported U.S. Cummins QSB4.5 engine features strong power,
stable and reliable performances, and good fuel economy. With the
application of constant speed control, the engine can automatically
adjust to idling state under non-working condition to save fuel.
The temperature controlled fan design and the load-sensing system
technology save the fuel cost for the user.
2.The vibratory drums adopt the uniform amplitude design, in which
the vibration edge and the drive edge are arranged in staggered
manner to realize more uniform compaction and smoother road.
3. The design of flexible startup and flexible stop can prevent the
occurrence of soil sediment during startup and stop of machine.
4. The speed control knob is equipped to set up the working speed
and impact cycles so that every working cycle is working under step
frequency to realize better compacting uniformity.
5. The water tank up to 1,100L capacity remarkably prolongs the
working time, with two filler ports and two outlet ports.
6. SR14D-3 vibration system includes two frequencies, namely 51Hz
and 67Hz, and its working efficiency is promoted by >34% than
that of traditional machines. The 0.3mm low vibration amplitude is
especially suitable for compacting thin layers and bridge surface
layers and the 0.8mm high vibration amplitude can be used for
compacting thick layers, featuring high compacting efficiency.
