Semi-trailers for Public Works: Robustness and low tare weight with Granalu
Our OP (Public Works) range covers all requirements for public works applications, such as the transport of aggregates, sand, asphalt mixes, earthmoving, excavation, rubble, sub-base materials, etc.
OP Range: Customised solutions for public works materials
The Granalu OP range includes two models:
Omega Evo model: The evolution of the leader
Omega Evo: Pioneers in technology, leaders in performance.
The Omega Evo model, patented by Granalu, has been Granalu’s flagship product for more than 20 years, as it was one of the pioneers in offering efficient transport solutions with an aerodynamic, lightweight and attractive design.
It is a model entirely manufactured with longitudinally arranged side panels and reduced welding requirements.
In addition, it features an improved curved profile to achieve excellent aerodynamics. All of the above translates into fuel savings for the tractor unit of up to 3% (profitability) and lower CO₂ emissions into the atmosphere (sustainability).
In addition, the Omega Evo model offers high resistance to wear thanks to its side panels with progressive thicknesses, making it an ideal model for public works. Not forgetting its ergonomics, designed to facilitate day-to-day work and prioritise safety.
COMPETITIVE ADVANTAGES of the Omega Evo semi-trailer:

Profiles
- Upper profile designed to achieve optimal behaviour under torsion and bending during demanding operations.
- Lower profile with progressive thicknesses for greater resistance to wear.
Slatted doors
- Swing, side-opening swing and universal.
- Cleaning and aesthetics.
100% welded horizontal profiles
- Reduced welding load.
- Greater robustness.
OP-Alpha model: For the most extreme challenges
OP-Alpha: New model with steel body for greater robustness
With 100% Granalu design and manufacture, the OP-Alpha features an aluminium chassis and steel body, and is designed for most public works operations: aggregates, gypsum, clays, gravel, ballast or asphalt mixes, among others. This makes it a highly versatile option for different types of load.
In addition, its body is manufactured in Hardox® 500 Tuf. Hardox® 500 Tuf is the latest wear plate in the Hardox® range, providing exceptional robustness, unmatched hardness and proven reliability.
COMPETITIVE ADVANTAGES of the OP-Alpha semi-trailer:
GREATER ROBUSTNESS
VERSATILITY IN LOADS
NEW BUMPER
- Unmatched robustness and reliability thanks to the strength of Hardox® 500 Tuf.
- Total versatility for any load: ideal for construction materials of different densities.
- New optimised bumper, greater usable height and anti-build-up design for perfect performance on site.
- With volumes from 22 to 28 m3.
- Tare weight from 5,300 kg.
- 100% Granalu manufacture = aluminium chassis + steel body

Plates
- Two configuration types:
- 1. 3 mm thick side panels and 4 mm thick floor
- 2. 4 mm thick side panels and 5 mm thick floor
- Offers high resistance, hardness and guaranteed toughness in a single wear plate.
- Nominal hardness of 500 HBW: ensures long service life and resistance to impacts.
Types of doors
- Swing (allows better sealing and robustness).
- Hydraulic (sealing, robustness and door opening without the need to tip).
Bumper
- New bumper: 820 mm ground clearance in the folded-down position to achieve greater usable height and a perfect fit with asphalt paver machines.
- Cylindrical shape that prevents material build-up.
- Manual or automatic.
