PRONAR trailer T679/4MN
The PRONAR T679/4MN is a construction trailer designed for the transport of heavy materials (e.g. rubble, stones, ballast and gravel) used during construction, earthmoving and demolition work, but it is also ideal for farms, gravel pits, stone quarries and construction companies.
The body of the trailer is made of two folded 4 mm thick metal sheets, reinforced around the perimeter with robust profiles with cross-sections increasing towards the rear, which makes it much easier to pick up loose material with, for example, an excavator bucket, without causing damage.
The design is based on tandem suspension with longitudinal control arms, which guarantees comfort and safety. The control arms operate independently of each other, so that the trailed trailer remains stable even on bumpy roads. Operation is also facilitated by tyres in size 400/600-15.5, which improves traction when driving on paved roads.
The load compartment is equipped with 4 load securing points (2 at the front and 2 at the rear) to secure the goods transported. The trailer’s mounted invasions facilitate the loading of construction machinery (e.g. a small excavator).
A wide range of optional extras (e.g. a body made of HARDOX® steel, a hinged tailgate and additional extensions increasing the capacity of the trailer from 4.5m3 to 11m3) allows the trailer to be adapted to the needs of the most demanding users.
