Traditional methods pose serious health risks

Although there are no hard and fast rules relating to how often a truck should be cleaned – with some operators opting for daily, while others adopt a more occasional / ad-hoc approach. It is widely acknowledged that allowing the concrete to build-up will have a detrimental effect on the overall performance of the truck and for this reason a preemptive approach is more beneficial.

The Ready Jet system greatly reduces maintenance costs that commonly come with repairing the blades and drum, as well as extending their overall lifespan. As well as this, the less residual concrete build-up on board, the more capacity there is for ‘fresh’ concrete and as the truck will be lighter, fuel efficiencies will be made (approximate fuel savings of $1000 per year). Not forgetting the more residual concrete build-up there is, the higher the health and safety risks are when it comes to manually removing from the drum.

Currently worldwide, manual cleaning is the most common and traditional method of clearing out residual concrete build-up from the drum and this involves operators physically climbing inside the drum via the small entry hatch, armed with a jackhammer or kango drill in order to chip away and loosen the set concrete.

Layers of residual concrete build-up with every delivery and chipping away at the concrete poses many safety hazards – falling debris is one of the biggest contributors to operator injuries during the cleaning process. The vibrations from the drill or jackhammer often loosens concrete from the roof of the drum, meaning a high risk of injury.

Last year, two people in America died from the injuries sustained from falling debris while carrying out routine maintenance to the mixer drum, with several other people hospitalized.

Chipping away at the concrete also means that the drum often becomes damaged and manually removing the concrete by traditional methods also exposes the operator to silica dust, a known carcinogen. Occupational exposure to silica dust over a period of years can result in Silicosis, a form of lung disease. There is also the health and safety issue of working in confined spaces as the rescuing of an injured operator is nearly impossible.
