Maintenance And Repair Of Concrete Mixer Truck

The definition of concrete mixer truck :

 

Equipped with mixing tube and power system equipment, used to transport concrete tank dedicated transport vehicles.

 

Mixers: second class chassis, transmission system, hydraulic system, frame, mixing tank, front-rear device, water supply system, control system, such as a ladder.

 

In terms of daily maintenance, concrete mixer truck should routinely for automobile engine, chassis parts, such as maintenance, also the following maintenance work must be done:

 

Clean concrete mixing drum and front-rear mouth:

 

Because the concrete will be solidified into a hard piece in a short time, and has certain corrosion to steel and paint, so the concrete tank after each use, wash the adhesion on the concrete tank and in and out of the mouth is the daily maintenance of concrete must be earnest to work.

 

Including:

 

A. before each loading wash with water inlet, the inlet moist when loading;

 

B. at the same time of loading to the conductor's own cleaning water tank filled with water;

 

C. charging after flushing inlet, wash the inlet near the residual concrete;

 

D. to the construction site after discharge, flushing discharge chute, then add clean water in the concrete tank within 30-40 L;In the car on the way to keep the concrete tank is slow rotation.

 

E. next door before charging off concrete tank in wastewater;

 

F. was done a thorough cleaning every day tank of concrete and the front-rear around the mouth, ensure no caked with cement and concrete.

 

Above these work as long as a don't seriously, will bring big trouble later work.

 

Maintenance Drive:

 

The driving device is driven to rotate concrete tank, take it by force, universal shaft, hydraulic pumps, hydraulic motors, control valves, hydraulic tank and cooling system components.

 

If this section due to failure to stop working, concrete tank will not turn, this will lead to concrete scrapped car, in serious cases, so that the entire concrete tank condensation in the tank, causing the mixer trucks scrapped.

 

Therefore, whether the drive is in use must be highly reliable attention. To ensure reliable drive intact, you should do the following maintenance work:

 

a. Universal rotating part is failure-prone area, shall be when lubrication and wear regular checks, and timely repair replacement. The team should spare universal shaft assembly to ensure the event of failure to resume work in a few minutes.

 

b. Ensure that the hydraulic oil clean. Concrete mixing truck harsh working environment, we must prevent sewage sediment from entering the hydraulic system. Hydraulic oil according to manuals require periodic replacement. Once the inspection found that the hydraulic oil mixed with water or sand, we should immediately stop cleaning the hydraulic system, replacement of hydraulic oil.

 

c. Ensure effective hydraulic oil cooling system. To regularly clean up the hydraulic oil cooler, radiator is blocked to avoid cement, checking electric radiator fan is functioning properly, prevent hydraulic oil temperature exceeded. Just make sure the hydraulic part of the hydraulic oil clean, the general failure much; 8x4 concrete mixer truck produced by different manufacturers, life is not the same.
