sold in last yearGeneral overview
Caterpillar 637 is a scraper designed for bulk earthmoving, hauling, and site preparation work on construction sites. It uses a 419 kW (570 hp) engine and is built around a heaped capacity of 38 m³ (49.7 cu yd), giving the model a high-volume material-moving profile. That combination places the model in the large scraper class used for moving soil and other loose material.
Its rated payload is 34,472 kg (76,000 lb), and the 3.51 m (11.5 ft) width-cut defines a broad cutting path for loading and transport cycles. Top speed is 55.8 km/h (34.7 mph), with reverse travel up to 9.9 km/h (6.2 mph), supporting repositioning across active earthmoving jobs. The listed capacity and travel speeds help define its operating scale within heavy earthmoving operations.
