Automated walking: Keith Walking Floor

Zyggy Reinoga, Keith Walking Floor Australia Manager, speaks to Waste Management Review about the company’s automated alternative to the tipping trailer.

The recently released 2019 Australian Infrastructure Audit examined key challenges faced by Australia’s waste sector including population growth, patchwork government regulation and transportation costs.

Without action, transporting waste will become more costly and as such, so will resource recovery, according to the report. This is attributed to significant distances between waste generation points and processing facilities. Zyggy Reinoga, Keith Walking Floor Australia Manager, says the limited technical efficiency of waste trailers is an additional factor.

“Loading and unloading waste trailers can be time consuming because operators have to clean the body out manually,” he says.

“There are also issues with cross contamination that stem from ineffective cleaning and a lack of automated loading and unloading, which results in wasted space and reduced payloads.”

To counteract these inefficiencies, Keith Walking Floor developed a fully automated walking floor trailer system that allows cargo to be safely and efficiently unloaded without the need of a tipping trailer.

“The introduction of the rugged V-Floor slat 15 years ago, allowed operators to process loads that other trailers had to pass on because of transportation challenges.”

The V-Floor system consists of a series of reciprocating slats that are powered by a hydraulic drive.

“As the floor moves through its four-phase cycle, every third slat moves together,” Zyggy says.

“During the final phase, all slats move in unison conveying the material. The friction of the load on the two sets of slats that remain in place keeps the load from moving, while the final set of slats moves.”

Zyggy says V-Floor slats are designed for high impact and abrasion, and are suitable for construction and demolition waste, scrap metal, aggregates and specialty waste products such as fly ash.

“Operators need to make the most of their trailers and waste transport vehicles, and backhauling can double the efficiency of a fleet – an added benefit of our automated system,”
he says.

“Our sweep system also cleans the floor of the trailer as it unloads to reduce payload cross contamination.”

According to Zyggy, the sweep system eliminates the need for brooms or manual tarps and provides a safer working environment as the operator never has to enter the trailer body.

Zyggy says the V-Floor system recently underwent a redesign to increase the versatility of its unloading floor.

“Major advantages include an increase in the floor area that actually moves the load, and a reduction in the weight of the slats,” he says.

Zyggy added that the V-Floor’s bearing support system increases the life of both the bearing and the V-Floor slat.

“Designed to handle a variety of waste products, our walking floor system offers many benefits over conventional tipper trailers, with the horizontal unloading action eliminating many of the hazards associated with tipper trailer unloading,” Zyggy says.
