With the promise that its customised transfer point solutions will always perform to expectations, Weba Chute Systems tackles its turnkey projects in a highly systematic and controlled manner.  The company has successfully carried out more than 25 turnkey projects in the past decade, according to Weba Chute Systems project manager Ted Cruickshank, including contracts in the mining, steel, ports and food industries. 

Among these substantial projects was the design, manufacture and installation of 36 chutes at a steel maker’s sinter plant in South Africa, and 11 chutes for a project house developing a mine in Zambia.

“More recently, we completed a turnkey project for a number of crusher chutes at a platinum mine in Zimbabwe,” says Ted. Further afield, Weba Chute Systems has provided chute designs to accommodate a three-way conveyor in an operation in Trinidad and Tobago in the Caribbean, now awaiting execution. 

Attention to detail

“It all starts with defining the project’s objectives and scope,” explains Ted. “This is followed by establishing the budget so that an accurate quotation can be prepared, as well as planning a timeline that meets the customer’s schedule.”

Efficient procurement allows fabrication to get underway without delay 

Turnkey projects demand clear channels of communication, he emphasises, so a regular meeting schedule is agreed with the customer to ensure that all stakeholders are kept informed throughout the project cycle. This is particularly important for dealing timeously with issues so that the project’s progress is not unduly impeded. 

“On some projects, we can work off the customer’s drawings, but we often go to site to conduct our own surveys, on which we base our calculations and designs,” Ted adds. Chute flow designs and layouts are then completed and approved, followed by fabrication approvals, all within a stringent Quality Control Plan (QCP). 

Eye on quality

“Our efficient procurement allows fabrication to get underway without delay, and stringent quality checks are carried out at every stage of manufacture, emphasising that rework needs to be avoided if projects are to run on-time and on-budget which means stringent quality control. Weba Chute Systems uses ISO 9001-2015 as the standard to document and control all quality related activities. 

“Regular audits and certifications help maintain a high level of consistency in the quality of our products across all projects. Quality inspections at different project locations ensures that the equipment adheres to the project’s quality standards.”

Mitigating risk

A risk assessment on each project identifies all potential hazards and is the basis for mitigation plans to reduce risk. There is also growing pressure on mines and their contractors to minimise environmental impacts. “Noise, dust and spillage are among the main environmental risks associated with transfer chutes,” notes Ted. “We mitigate these impacts through optimising the flow dynamics in our tailored chute designs while accommodating the specific conditions of each application.”

This includes understanding the material’s characteristics and particle size distribution, as well as its flow rate, trajectory, velocity and points of impact. Optimised material flow decreases the turbulence at the transfer point, in turn reducing dust and noise. Smooth transfer of material to and from conveyor belts also cuts the spillage and improves health and safety conditions around the belts.

Project planning

Ted highlights the value of project planning software to plan and monitor progress during turnkey projects. These tools enhance real-time collaboration and efficiency, with other enabling technologies including three-dimensional modelling and data management. 

“We also use video conferencing and cloud-based document handling to streamline our communication with customers and other parties to the project,” he says. “This improves overall efficiency and resource coordination.”

Ted concludes by stressing the value of local suppliers, engineers and partners in the country where the turnkey project is being executed. Weba Chute Systems prioritises these links by building positive long term relationships with local partners to overcome potential barriers of culture, language, lead times and cost efficiency.
