After running a one-brand fleet for many years, in 2015, southern Africa’s largest waste management company, EnviroServ, decided to diversify and went on to purchase one Scania truck. Three years later, the fleet has expanded to 23 units, and counting, as both Scania South Africa and the product continue to serve beyond expectations.

As the largest waste management company in southern Africa, with a specific focus on the industrial sector, EnviroServ is a big fleet owner that runs about 250 trucks, all the way from 4-t units to the extra-heavies. Apart from South Africa, which constitutes 80% of the company’s business at this stage, EnviroServ also has operations in Mozambique, Kenya and Uganda. The majority of the fleet runs across its four major centres in Cape Town, Port Elizabeth, KwaZulu-Natal and Johannesburg. 

“Most of our business is in the industrial sector, including cement, petrochemicals, construction, manufacturing, metallurgical, mining, oil & gas and power generation, among others,” explains Rakesh Seetal, Head of Procurement: Southern Africa at EnviroServ. “We also do a lot of municipal work, and these partnerships with local governments form a crucial part of our business.”

Considering the uptime conscious nature of EnviroServ’s application range, the company has always placed premium products at the heart of its business. Having joined EnviroServ as head of technical some six years ago, Seetal took over as the head of procurement in 2015.  At the time, 95% of the truck fleet was single branded, a situation Seetal regarded as unhealthy. Consequently, he immediately placed fleet diversification on his agenda.

The biggest driver in EnviroServ’s decision to bolster its Scania fleet was the OEM’s willingness to tailor the deals to the company’s operating needs. “One of their custom needs was the longer maintenance periods from the normal 64 to 84 months,” explains Naas Burger, sales executive at Scania SA.

“Scania was the first company to offer us the flexibility to increase the maintenance contracts from the industry standard of five years, to seven years. We negotiated for longer maintenance contracts in line with our business needs. For such a big ask, I didn’t necessarily need to go and meet the managing director of Scania South Africa, but Naas was able to sort out all our requirements. This speaks volumes about the company’s flexibility and the empowerment of customer-facing individuals within the organisation,” says Seetal. 

Combining capabilities of a skid and TLB in one

Hidromek HMK62SS Maximum Scottys 09 2018 001A new Hidromek mini-TLB launched locally by supplier Maximum Equipment is set to revolutionise the industry with its combined capabilities of a skid-steer and a backhoe loader in one machine. Durban-based plant hire company, Scotty’s Plant Hire recently took delivery of two of the first six units to be sold in South Africa, and the machines have performed beyond expectations thus far.

Maximum Equipment, the exclusive distributor of the Hidromek range of excavators and backhoe loaders in South Africa, reports that the range has drawn immediate interest from both local contractors and plant hire companies. “We have had lots of interest in the machine since we launched it locally. Customers are impressed by the power and strength of the machine,” says Vaughan Ellis, MD of Maximum Equipment.

Scotty’s Plant Hire is one of the very first recipients of the new range in South Africa. The company purchased the two of the six units to be sold in South Africa, and MD and owner Brian Scott has been impressed by the performance to date. Based in KwaZulu-Natal, Scotty’s Plant Hire has been hiring earthmoving equipment to the construction industry for more than 30 years.

“I am very impressed with the Hidromek HMK62SS. I am of the view that it’s only a matter of time before the machine establishes itself in the market. For me, it is more than a skid-steer loader, but slightly less than its ‘big brother’ the TLB,” says Scott. “I should also commend Maximum Equipment for their unparalleled product support and aftersales service. They are always checking on us and are willing to go the extra mile to help us meet our operational targets.”

Addressing quality parameters in crushing

Terex Finlay 8459 Crusher 09 2018 001In Part 1 of our crushing-focused series of articles, we alluded to the substance of optimum crushing in the whole aggregate production equation. In this feature, our panel of experts further delves into product quality parameters and the significance of close cooperation between the supplier and the customer in order to come up with the best crushing solution for the job at hand.

Quality parameters in aggregate production are normally based on strength, size and shape of the end product. How does the end result help determine what type of crusher is needed? Johann Pruewasser, engineer at Keestrack, says to determine the most economical crusher for the job at hand, project considerations always have to start at the end. “This means that all tooling deliberations have to be informed by the quality demand of the final product, and then go step by step from the end of the process to the primary crushing stage,” says Pruewasser.

Dewald Janse van Rensburg, MD of B&E International, says the final product requirement is the cornerstone of equipment selection and plant design, and certain combinations of jaw crushers and secondary crushers have proved to be more effective in achieving certain outcomes. “Customer requirements will also specify the grading envelope that must be achieved, which is the ratio between the coarser and finer aggregates. For any operation, the intended throughput rate is another key consideration in the choice of crushers and their sizes, and with commercial operations the market will dictate the level of demand to be satisfied, or the draw-off requirement for a specific project,” says Van Rensburg.

Tyron Ravenscroft, Finlay product manager at Bell Equipment, says the strength of the material determines the crushing ratios acceptable to that material and how many crushers will be required to crush the run of mine (ROM) to the desired product sizes. “The size of the ROM will determine the size of the primary crusher to accept the ROM. The ROM size will also determine the number of crushers required to produce the desired product sizes in the acceptable crushing ratios,” says Ravenscroft.
