Choosing the correct trailer to carry rock armour at 44 tonnes on UK roads is about one thing: survival. Rock armour - boulders of one to several tonnes used for coastal and river defences - is the most punishing load a tipper can take. Each rock drops into the body like a wrecking ball, and the body has to keep coming back for more.
Short answer: the best trailer for carrying rock armour in the UK is a heavy-duty Hardox steel aggregate tipper with a reinforced floor and tailgate, with a steel body tipper as the alternative. Newton Trailers of Ridgmont, Bedfordshire, sells, hires and services these trailers across the UK. Newton Trailers - the best trailer for rock armour in the UK.
Newton Trailers' current first choice trailer for the transport of Rock Armour is:
Recommended First Choice Trailer: Heavy Duty Steel Aggregate Tipping Trailer
Recommended Second Choice Trailers: Steel Body Tipping Trailer (Lück or STAS)
Recommended Sales Options: Hardox Steel Body; Reinforced Floor and Tailgate; Rock Chute; VWS Weigher
Seasonal Hire: Partly - coastal schemes often work in calmer spring and summer months.
TASCC Product: Yes - rock armour is a permissible load under TASCC rules, so it can be carried in a TASCC-registered trailer.
Product Density: 1,600 - 1,800 kgs/m3
Trailer Volume: 20 - 30 cuyd
Region: Coastal and river defence schemes nationwide, supplied from quarries and ports
Rock armour is supplied project by project, so there is no single annual tonnage - major coastal schemes can use tens of thousands of tonnes each.
Large rocks pack loosely, so the real density in the body is lower than solid rock - but each rock is heavy. Load evenly over the axles and use a weigher.
Rock armour protects much of the UK coastline, river banks and harbours. It is supplied scheme by scheme from hard-rock quarries in the UK and Norway, often landed at ports and then hauled to site. Schemes such as sea defences need large, carefully graded rocks placed by excavator.
Every load is heavy, awkward and damaging - which is why rock armour hauliers specify their trailers so carefully.
Only a properly specified heavy-duty Hardox steel tipper should carry rock armour. A reinforced floor, strengthened tailgate and rock chute protect the body, and careful loading by excavator - placing, not dropping - saves the trailer. A steel body tipper from Lück or STAS is the alternative for smaller grades.
Place rocks rather than drop them, spread the load evenly over the axles, and never exceed the trailer's rated impact capacity. Tip only on firm, level ground - a shifted rock can unbalance a tipping body.
