XM503 road milling machine is an asphalt road maintenance and
construction machine mainly used for the maintenance operations
of municipal roads and as the auxiliary construction implement
for large milling machines.
It can realize the small-area digging and renovation of
asphalt concrete pavements, including highways, downtown
roads, airports, cargo yards, and parking lots, and can be
used for the removal of road bulges, asphalt ripples,
overlapping curves, and tracks and for the scuffing of cement
roads and the milling of pavement jumps. It can realize the
milling along edges and manhole covers. It can realize the
road crushing function if the optional hydraulic pickaxe is
installed and realize the milling of roadside rumble strips
if the optional rumble wheel is installed.
Featuring high working efficiency, simple construction
processes, easy control of milling depth, easy and flexible
operations, and good mobility, this machine is an ideal
machine for repair, renovation, and maintenance of asphalt
roads.
Performance
Characteristics:
* Traveling system:
Wheeled type, all-wheel (three-wheel) drive, hydraulic +
mechanical drive mode, constantly variable speed change, and
high and low gears. The rear wheels adopt independently
suspended support wheels. The right rear wheel can swing
inward to ease the milling along edges.
* Milling system: The
hydraulic + mechanical drive mode is applied to achieve
efficient and powerful milling. The imported milling cutter
heads guarantee the working life of milling cutter.
* Control of milling
depth: The left and right rear outriggers can be
vertically adjusted to allow the wedged milling. The rear
outriggers are installed with depth indicator to indicate the
milling depth. This machine can be installed with optional
automatic leveling system.
* Steering system:
The full-hydraulic single-front-wheel steering features small
steering radius and flexible steering.
* Sprinkling system:
The sector-shaped water spray nozzles spray water to the
milling cutter heads to cool the milling cutter and at the
same time reduce the diffusion of dusts during milling. The
high capacity water tank can realize the longer working time
of machine without interruption. The electric-driven water
pump eases the disassembling and cleaning of water spray
nozzles.
