Description

Technical Field

[0002] The unloading device of a concrete mixer truck is a device used to unload concrete from the mixing drum of the mixer truck to the construction site. These devices are designed to achieve fast, efficient and safe unloading while minimizing concrete waste and pollution. Unloading is generally done by rotating the mixing drum so that the concrete flows from the inside of the drum to the outside. The device is usually driven by a hydraulic system, which allows the mixing drum to rotate at different angles and directions so that the concrete can be unloaded to the required position and flow out from the side. The hydraulic system can also be used to control the tilt angle of the mixing drum so as to accurately control the unloading position of the concrete.
