Transit mixer is a kind of special truck that is used to transport concrete for
engineering construction, it is also called “olive truck” because of its
appearance. The mixing drum will keep rotating to prevent the concrete in the
mixing drum from solidification during the transporting process. The mixing
drum should be cleaned with fresh water after used to avoid the remaining
concrete becoming solidified and reducing the capacity of the mixing drum.
The concrete mixer machine consists of motor chassis and concrete mixing devices. Generally,
the mixing devices include mixing drum, decelerator, hydraulic system, operating
and cleaning system. The mixer truck’s working procedures start from getting
power from the motor chassis and driving the hydraulic pump, transferring the
mechanical power into hydraulic power and sending it to the constant motor,
then driving the decelerator and mixing devices to mix the concrete.
Daily maintenance is very important for transit mixer to keep a good condition for a long
time. Lubricant should be paint regularly to avoid frequent abrasion. The
hydraulic oil should be kept clean and as specified, the sewage should not
enter the hydraulic system, especially in the tough working environment.
Replace the hydraulic oil once mixed with water or sand. Keep the cooling
devices effective and regularly clean the hydraulic radiator to prevent being
blocked. Having a good knowledge of the maintenance guidelines can not only
extend the machine’s service life but also reduce downtime and save cost.
