old concrete mixer trucks
Old concrete mixer trucks represent a cornerstone of construction history, serving as reliable workhorses in the building industry for decades. These vehicles combine transportation capabilities with continuous mixing functionality, ensuring concrete remains workable throughout delivery. Traditional models typically feature a rotating drum mounted on a truck chassis, with capacities ranging from 6 to 10 cubic meters. The drum's spiral blade design maintains consistent mixing during transport, while the hydraulic systems control drum rotation speed and direction. Notable features include a water tank for adjusting concrete consistency, manual or automated controls for drum operation, and a discharge chute system for precise concrete placement. These trucks operate through a power take-off system connected to the truck's engine, enabling efficient drum rotation while stationary or in motion. Despite their age, many old mixer trucks demonstrate remarkable durability, with robust framework construction and simplified mechanical systems that facilitate maintenance. The basic operational principle involves loading materials at the batch plant, mixing during transport, and delivering ready-mixed concrete to construction sites, making them indispensable for small to medium-sized construction projects.
