New paving products from Cat

摘要

Anew line of 8-foot size class pavers for urban and rural applications has joined Caterpillar's paving products family. The paver and screed combinations include the AP400, AP455, AP500, and AP555 asphalt pavers as well as the SE47 V and SE47 FM asphalt screeds. The standard paving range for the SE47 V screed is 8 to 15-feet 6 inches, (2.4 to 4.7 m) with a maximum width of 20 feet (6.1 m). The standard paving range of the SE47 FM screed is 8 to 15 feet, 6 inches (2.4 to 4.7 m) with a maximum width of 20 feet, 6 inches (6.2 m). Paving depths up to 10 inches (254 mm) support aggregate paving applications. Cat's Mobil-trac undercarriage on the AP455 and AP555 uses a four-bogie system with self-tensioning accumulators and centre guide blocks help prevent slippage and reduce wear, while the oscillating bogie wheels help deliver smooth transitions when exiting the cut over transverse joints of mill and fill applications.
