History and service record of BM 5350B to BM A25 6x6

  • 5350B 6x6 archive record. Volvo's archive of past products lists the BM 5350B 6x6 articulated hauler with a production year of 1983 to 1987, a Volvo TD 70 G engine up to serial number 2760 and a Volvo TD 71 GA (157 kW, 213 hp gross) from serial 2761, and a load capacity of 22,500 kg. 5350B 6x6, Volvo BM, Volvo Construction Equipment.
  • A25 6x6. The Volvo BM A25 6x6 carried 22,500 kg (25 short tons) at up to 51 km/h with articulated steering and a six-wheel-drive bogie, and a 1990 example is listed in Finland; Volvo keeps past-products pages for the 5350B and the A25 6x6. A25 6x6, Volvo BM past products, Volvo Construction Equipment.
  • Livab and Volvo BM. Livab was absorbed into Volvo BM in 1974, building on the articulated hauler that Volvo introduced in 1966. Articulated hauler, Wikipedia.
  • BM A25 6x6 archive entry. Volvo CE's archive entry for the BM A25 6x6 says it had a payload capacity of 22,500 kg (25 short tons), a top speed of 51 km/h (31.2 mph), articulated steering with an all-terrain bogie and six-wheel drive for mixed and very difficult ground. A25 6x6, Volvo BM past products, Volvo Construction Equipment.
  • BM 5350 built for bulk haulage. Volvo CE says the BM 5350 was designed to run at high average speeds, was fast and agile on load and dump cycles, and was developed from the ground up for profitable bulk haulage under widely varying conditions. 5350, Volvo BM past products, Volvo Construction Equipment.
  • A20C as the small hauler. The Volvo A20C 6x6 is described in the archive as small, agile and six-wheel drive, the choice for small jobs and stationary installations where maximum load capacity was not needed. A20C 6x6, Volvo past products, Volvo Construction Equipment.
  • Where Volvo's articulated hauler came from. Wikipedia says Volvo is the segment leader with half of global sales and the pioneer that brought the articulated hauler to market in 1966, after Livab began developing a specialised dump vehicle with Bolinder-Munktell in 1955 and then dropped the tractor's front axle so steering came from hydraulic cylinders between the units. Articulated hauler, Wikipedia.
  • DR 631 and DR 860. The first purpose-built articulated hauler was the Volvo-BM DR 631, a 4x4 released in 1966, followed by a larger 6x6 DR 860 in 1968, while a rival's KL 411 4x4 dumper arrived in 1967 and competed with Volvo BM until that firm was bought in 1982. Articulated hauler, Wikipedia.
