Self-loading concrete mixers are equipment that self-loads aggregates, blends concrete, weighs the batch, and places the concrete where it is required. These are stand-alone machines that complete concrete mixing tasks that only demand one worker to operate this type of machine.
Self-loading concrete mixers(hormigonera autocargable) are unique machines that are mainly used in construction sectors across the globe. Today, there are various types of self-loading concrete machines on the market and each type has its own set of pros and cons. Every type is all-terrain and highway machines, used mainly for the construction of bridges, canals, industrial, commercial, and residential buildings, along with other types of construction applications.
The Working Principle Of The Self-Loading Concrete Mixers
The stand-out feature of the self-loading mixers is their simple operation. Due to the self-loading design, these machines can automatically transport and produce concrete on-site. Here are some of the added features of the self-loading concrete mixers:
– Self-loading concrete mixers are multi-functional machines that can self-load all types of aggregates and concrete ingredients, transport, mix, and discharge.
– Self-loading concrete mixers usually feature four-wheel-drive systems that provide high traction that helps these machines work in soft-clay site conditions.
– These machines(auto hormigoneras) feature hydraulic-driven drums that provide superior rotation that promotes efficient mixing operations. As soon as the mixture is ready it is easy to lift the drum for effective and fast discharge of the concrete.
– Self-loading mixers also feature metal buckets which allow the operators to load the raw materials directly into the drum.
– The mixing and loading operations, the direction, and the speed of the drums are controlled from a cabin of a truck.
– Self-loading concrete mixers are easy to load onto a large truck where they can be transported to long-distance construction sites. This is a feature that makes these machines suitable for isolated, narrow, and small construction sites.
Components Of The Self-Loading Concrete Mixers
The typical components of the self-loading concrete mixers include the following:
– Loading System
The loading system is made up of hydraulic shovels that load the materials accurately and easily. Some manufacturers(fabricantes) include shovels that come with blades that allow the operator to cut open cement bags during loading. The capacity of the hydraulic systems vary and usually depends on the overall load-bearing capacity associated with the mixer.
– Weighing System
The weighing system is made up of computerized weighing parts that display and control the weights of the materials.
– Mixing System
Mixing systems help to mix the water, cement, and aggregate fed into the mixing drum. This drum is powered by an engine that delivers high quality and a homogenous mixture of concrete.
– Discharging System
The discharging system allows the operator the choice to discharge concrete at different heights and angles. Adjusting the angle of the drum is made possible by the handle shank inside the operator’s cabin.
– Wheel System
The 4-wheel drive system on a self-loading concrete mixer allows operators to travel over tough terrains which are common on construction sites. The tires on these mixers come with high-resistant engineering tires.
Working Principles Of Self-Loading Concrete Mixers
The entire concrete mixing tasks are performed by one operator. To start with, cement will be manually displaced into a bucket, and the water is then fed into a drum. The bucket-loading operation is designed to collect the aggregates and sand to load the drum that rotates efficiently and quickly. The high-speed drum makes sure the concrete mix is homogenous so that it can be placed and transported wherever it is required.
