Cement mixer trucks are one of the most essential machines in a construction site. They have one of the heaviest roles. These trucks have a revolving drum that mixes components to form concrete. It also keeps the concrete from drying, giving workers enough time to prepare before pouring.
Because of their heavy role in the construction site, cement mixer trucks needed all the care and attention they deserve to prolong their life and serve for a longer time. This article will touch on different points to mind in maintaining the cement mixer truck’s drum.
Signs of bad maintenance of the cement mixer truck’s drum
Like any other machine, cement mixer trucks have moving parts that wear and tear over time and frequent use. When these parts do wear and tear, they affect the whole machine and make it inoperable or inefficient. Here are some signs that could tell one that a cement mixer truck unit is badly maintained.
- Jerking and halts in the cement drum rotation. Jerking and even halting of the cement drum rotation is a clear sign that the truck accessory is badly maintained. These unusual movements can be a sign that there is too much leftover dried concrete inside the drum or the gears have worn out. Make sure to consult a mechanic and have him or her run a diagnostic test to detect a truck’s problem.
- Older material is present in fresh concrete. Another problem that could be blamed on an excess of dried concrete inside the cement mixer truck’s drum is the mixing of older hardened concrete with a fresh one. These older bits of material could negatively affect the strength and appearance of the mix by creating lumps.
Cement mixer drum accessory maintenance
A cement mixer truck’s drum is the most abused part of the unit. It is the part most vulnerable to wear and tear. To prolong its life, one should have these points in mind in maintaining it:
- Bolt check. Cement truck units have multiple moving parts and these movements create vibrations that may cause loose bolts over time. It is important to regularly tighten these bolts to avoid breakdowns and delays in the site.
- Bearings check. Bearings are also used in rotating the mixing drum. These bearings may break down over time and need replacing.
- Lubrication. The surface that connects the roller and the raceway should be well-lubricated to avoid jerking motion and for a smoother rotation.
- Dirt cleaning. Ideally, a cement mixer truck’s drum should be cleaned every three months. Not cleaning the drum regularly may lead to a buildup of old, crusty cement that may affect the quality of the next mix.
- Hydraulic components check. Maintaining the hydraulic system of concrete mixer trucks is simple as one just has to change the hydraulic oil regularly. The filter screen should also be replaced from time to time.
