The Improved Design of Self Loading Transit Mixer

2021-10-18

In addition to the conventional self loading, mixing, discharging, transport, the self loading transit mixer’s design and practical functions have been continuously improved. There is a simple analysis of its some design in actual uses.

Synchronous Displacement of Cab and Mixing Drum

The design of the integrated displacement of the cab and the mixing tank in the same position, to a certain extent, helps the driver to better observe the position of the discharge port and the discharge amount during discharge, which improves the accuracy rate.

But at the same time, the disadvantages should not be underestimated. On the one hand, since the driver's cab rotates synchronously with the tank, the driver is moving along a circular trajectory with a radius of about three meters. In this case, the driver is prone to fatigue. It also increases the bearing strength of the bottom turntable, which is undoubtedly a big hidden danger to the long-term operation of the turntable.

If you only need to improve the accuracy of unloading, you can install a camera on the rearview mirror of the mixer truck and display the output situation in the cab.

Integrated Design of Hydraulic Shovel and Mixing Tank

Now many manufacturers have slowly improved the installation method of the loading bucket, and began to separate the loading bucket from the tank body, and the direction of the bucket was fixed in parallel with the cab instead of being installed on the tank chassis.

On the one hand, the direction of the bucket itself when loading materials needs to be synchronized with the cab for shoveling. On the other hand, the weight of the bucket and the boom is also an issue that cannot be ignored. When installed on the tank chassis for a long time, the direction of gravity is reflected on the chassis and always acts on a point on the turntable. In this way, the damage to the chassis is also great.

A combination of the first four and the back two tires

This design seems to increase the load-carrying capacity of the self mixing concrete truck, but in the practical projects, some foreign objects such as rocks will inevitably be squeezed between two adjacent tires, which will influence the service life of tires.
