Product Definition
A second-hand car mixer refers to a mobile concrete mixing device that has completed part of its service life but still maintains stable working performance. It integrates the mixing system with the car chassis and has dual functions of transportation and mixing. This type of equipment usually has completed the main value depreciation in the second-hand market, and its price is only 40% to 60% of that of a new machine. It is an economical choice for small and medium-sized concrete construction enterprises.
Basic Parameters
The stirring capacity of mainstream second-hand equipment is usually between 6 and 12 cubic meters, the rotational speed of the stirring drum is maintained at 8 to 15 revolutions per minute, and the unloading speed reaches 1 to 2 cubic meters per minute. The chassis mostly adopts six-wheel drive heavy-duty trucks, with engine power ranging from 300 to 400 horsepower. The working pressure of the hydraulic system is maintained within the range of 18 to 25 megapascals, and the original factory's intelligent control system and fault diagnosis function are retained. The mixing drum is made of wear-resistant alloy steel plates, and its remaining service life usually reaches 50% to 70%.
