Intended use


HYDROG Road Wideners are intended for high efficiency paving with aggregate, breakstone, gravel, dry concrete, and hot asphalt. These machines significantly increase productivity in comparison with the manual paving or using graders. A team of 3 workers is able to pave several kilometres of the road shoulder within a single shift. The aesthetics of the paved shoulder is incomparable.
One HYDROG road widener can be used with many different carriers using of replaceable adapter plates.
Working units of the DG-1500 are independent from the carrier.

The best road widener available*


Paving with cold materials (aggregate, breakstone, reclaimed asphalt pavement, concrete for stabilization) and hot asphalt up to 200 °C
Paving output: 6-12 km/day
Carriers: loaders, backhoe loaders, tractors, graders, Unimog etc.
Replaceable adapter plates for different carriers.

High efficiency = time and money savings


Paving width with hydraulic adjustment and extension units
Hydraulically adjusted gradient
Paving depth with hydraulic adjustment - up to 300 mm below the road level
Possibility of paving above the road level
Paving behind the curb

Protection against pressing by the dump truck box


Variable storage hopper geometry
At contact with the dump truck, front wall is lowered hydraulically
Hopper with enough space for various tipper bodies
Front wall lifted hydraulically after tipper departure
Suitable to any tipper type

Durable solid tyres


4 pcs, large diameter double wheels with solid tyres
The wheels are strong enough to transport the weight several times greater than the machine weight with material
16 ton wheel load rating
A special shape of forks ensures the correct wheel positioning on uneven surfaces


High power diesel engine


26 HP
Perkins diesel engine - 3 cylinder

High power provides efficient operation even while paving of heavy hot asphalt
Low fuel consumption - approx. 3 l / h (depending on working conditions)
Easy maintenance

SOFT CONTACT System


Hydraulic adjustment of bumper
Hydraulic and pneumatic shock absorption system when the tipper approaches to the bumper
Soft contact with tipper body - also large tippers
No overloads, no collisions, no risk of machine damage
High comfort and operation safety

Suitable adapter plates for different carriers


for loaders
for three-point hitch of a large tractors
for graders
for wheeled excavator
for individual hydraulic lifts

Additional equipment


Spreading blade vibrator - uniform spreading of material at higher widths
Rear disk brush - replaces a single additional worker
Operator station with safe and ergonomic seat
Intuitive control panel separated from the hydraulics (easy and fast installation).

High quality


The whole machine frame sandblasted
Professional painting with two zinc primers and RAL-3020 top coat
All components of leading manufacturers
Quality control on each production stage
