Krone upgrades Profi Liner trailer
Trailer manufacturer Krone has completely redesigned its all-round Profi Liner trailer, paying special attention to the front wall, superstructure, floor, load securing and the rear.
Krone has opted for a welded ladder frame design with end-to-end longitudinal beams and profiled transverse beams for the trailer’s new, improved chassis concept. This design makes it possible to use smaller base plates, says Krone, which in turn makes repairs easier.
Phenolic plywood base plates are installed; these are said to transfer forces in all directions better than other floor concepts. The new Krone Profi Liner can be approved in accordance with EN 283 for forklift axle loads up to 8t (standard 7t). The base plates are attached with permanently elastic high-performance adhesive, which is said to ensure outstanding impermeability.
The Profi Liner is fitted as standard with a raised floor assembly in the front area. The plywood rebound plate screwed to the front wall ensures additional protection and stability. The front wall is firmly screwed to the frame.
Reinforced, pre-galvanised, armour-plated corner posts ensure optimum chassis connection, while offering protection against impacting mesh boxes at the same time. The pre-galvanised coupling support with the combination distributor are said to ensure quick and easy handling when hitching and unhitching the vehicle.
Krone has optimised the bulb plate in the rear area; thanks to the use of a special adhesive and bent plate down towards the edge, the floor is said to offer maximum protection, even if the vehicle is frequently loaded and unloaded from the rear.
The underrun protection and the lighting brackets, which are manufactured as individual components, also provide practical features. The separate and screwed version can be quickly replaced in case of damage.
The new modular rear buffer concept is also impressive, says Krone; for example, it allows the customer to quickly and easily respond to changing ramp/tour requirements and replace or retrofit the buffers.
The new container doors featuring fully galvanised components and an improved door seal are produced in fully automated production facilities to ensure quality and precision. Krone has also redesigned the rear post connection, which now features holes for cross strapping as standard.
As with all add-on parts, the new roof hood is pre-galvanised and treated with a cathodic dip and powder coating as standard; the roof cover geometry has also been optimised, making it much easier to thread the curtain tension bar. The roof can also be optionally equipped with straps and opened from front to back.
The Profi Liner is equipped with the new Krone canopy as standard. Like the new Edscha Hybrid canopy, it has 30 mm wide, welded-on aramid straps. This allows the strength to be increased significantly.
Krone now also fits the vehicle with offset curtain rollers, which reduce contact with the external beam seal and improve running characteristics.
The double curtain with the additional roller makes it possible to quickly and easily thread the curtains at the rear, says the company.
The Multi Lock external frame with strapping options at 100 mm intervals is said to ensure professional load security. The inside of the frame is pre-galvanised and treated with cathodic dip and powder coating for corrosion protection.
Its profile has been enlarged to optimise the coating process. Additional slotted holes were also integrated at the bottom of the frame to reduce the accumulation of dirt and moisture. In addition, the closed profile of the Multi Lock external frame is said to offer optimum impermeability towards the cargo area.
Meanwhile, the Safe Curtain incorporates high-strength spring steel strips in vertical PVC tunnel pockets integrated into the side curtains. With this technology, Krone offers a load securing system using the side curtain, meaning that the classical plug-in laths can be dispensed with.
This not only makes handling the Safe Curtain easier, safer and faster, says Krone, but also reduces the weight by about 100 kg compared to conventional side curtains with plug-in laths.
The integrated spring steel strips also provide an anti-theft function in the vertical direction: If the curtain is deliberately cut, it is only possible to cut to the next spring steel strip. Repairing the curtain is also just as simple as with a standard side curtain, says Krone. Work-related accidents caused by falling plug-in laths are also avoided.
The semitrailer is outfitted with a Krone axle which includes a six-year guarantee without mileage limitation for on-road use within the EU.
