On the Cover: In a ground-breaking delivery, Scania has handed over a 20-unit fleet of Scania R 560 A6x4HZ CR20N trucks to its longstanding customer, Reinhardt Transport Group. The transport giant is one of Scania South Africa’s biggest tipper transportation customers, operating in excess of 700 Scania trucks at the moment.
The 20 trucks, explains Johnny-Ray Basset, key accounts manager at Scania South Africa, have been deployed in a mining application in Mpumalanga, transporting mining products between Steelpoort, in the Limpopo province of South Africa, and Maputo, Mozambique. The first 10 of the new trucks were delivered during the second week of August, and the second batch of 10 followed during the third week of the same month.
The new fleet ushers in a new era for both Scania and the customer, as it is the first Scania fleet in South Africa to be designed and operated under the Performance-Based Standards (Smart Trucks) framework. The Performance-Based Standards (PBS) Scheme offers the heavy vehicle industry the potential to achieve higher productivity and safety through innovative and optimised vehicle design.
PBS vehicles are designed to perform their tasks as productively, safely and sustainably as possible, and to operate on networks that are appropriate for their level of performance. The basic principle of PBS is matching the right vehicles to the right tasks.
Understanding the cost effect of crusher liners
In the current economic climate, cost base is a major factor in managing a successful crushing business, and wear costs associated with crushing can be a major cost item. How significant are crusher liners in the overall cost equation of running a crusher and how can quarries reduce costs related to this component?
Crusher liners are wear items exposed to the material entering the crusher chamber during crushing. As such, says Tyron Ravenscroft, Finlay Product Manager at Bell Equipment – Terex Finlay’s dealer in southern Africa, they need replacement once completely worn. Should they not be replaced, he says, extensive damage can be transferred to the crusher itself. Such damage can be in the form of premature bearing failures, cracking of the crusher chamber castings and signs of wear on the crusher chamber casting itself.
Juha-Pekka Vilpas, Parts Product Manager at McCloskey, says that as crushing is an abrasive process, the crusher liners protect crusher structures and components by being the main crushing contact surface. Crusher liners’ shape, he adds, can also have a big effect on the crushing result in terms of particle shape and gradation.
According to Jorge Abelho, Director Technical Support at Pilot Crushtec International, a liner is a sacrificial part designed to protect and prolong the life of the very expensive machine by isolating the machine’s structural components from material being processed. The machine’s structural components are designed for strength and durability whereas the liners have different qualities designed for abrasion resistance, toughness and impact resistance.
“The industry term, ‘crusher liners, refers to a specialised set of sacrificial liners within a jaw or cone crusher. These special liners are subjected to the full compressive forces inside a crushing chamber and absorb large amounts of energy. They are not your typical liners you would find in other materials handling machines,” he says.
Crusher liners serve several very important purposes inside a crusher. The first and most important task is to protect the crusher from expensive or irreparable damage. The liner material is ductile and can endure plastic deformation without fracturing. By having the correct chemical composition, with a special manufacturing process, these liners protect
Keeping insurance cover during COVID-19
The impact of COVID-19 on the capital equipment sector is far-reaching, with many businesses experiencing crippling financial constraints. Despite the financial pressures brought about by the pandemic, it is critical for equipment owners to maintain their insurance cover to ensure security for their mission-critical assets.
Disasters can be financially devastating and can seriously disrupt business. Despite the current economic hardships due to the COVID-19 pandemic, insuring assets is a sound risk management strategy. Asset insurance passes the risk of loss or damage to mission-critical assets from the business to the insurance company. This represents a safety net that reduces the financial impact of loss or damage to expensive movable assets like capital equipment.
Notwithstanding the devastating impact of COVID-19, many capital equipment businesses are keeping their insurance cover. “The vast majority of clients are maintaining their cover. We are, however, experiencing an increase in clients who simply can’t afford their insurance premiums anymore, as well as companies that had to close their doors because of the financial implications the lockdown had on their businesses,” explains Christiaan Steyn, head of MiWay Business Insurance.
The same view is shared by Neil Botha, Scania Finance South Africa’s insurance manager, who says most Scania Insurance customers have kept their cover, except for those who did not operate at full capacity. “For these clients we have allowed them to change their cover to third party, fire and theft. This option allows for a reduction in premiums, while the assets are parked and not in operation,” says Botha.
