A Double trailers truck also known as tandem truck is a type of heavy-duty vehicle designed with one front axle and two rear axles, each fitted with dual wheels. This configuration enhances load distribution, stability, and traction, making it suitable for transporting heavier loads over long distances or rough terrains. The extra axle helps distribute the weight more evenly, reducing wear on roads and increasing fuel efficiency compared to single-axle trucks.
In terms of capacity, tandem trucks can carry significantly heavier loads than single-axle trucks. Their load capacity typically ranges from 12,500 to 28,000 pounds, depending on the truck model and specifications. Some specialized tandem trucks, such as dump trucks or cement mixers, may have reinforced frames and suspensions to handle even greater weights.
Regarding applications, tandem trucks are widely used in construction, transportation, and emergency services. Dump trucks with tandem axles are common in construction for hauling gravel, sand, and debris. Tanker trucks use this design for transporting fuel, chemicals, or water, ensuring better weight distribution. Fire trucks also often feature a tandem axle setup to carry large amounts of water and firefighting equipment while maintaining maneuverability. The dual-axle system allows these trucks to operate efficiently on rough terrain or steep inclines, making them essential for industries requiring heavy-duty transportation.
