An excavation and transport company has purchased a Zaxis-6 super long front excavator (video) to work on a longstanding project at a brick factory near Pannerden in the east of The Netherlands. Delivered in October 2017, the Hitachi ZX300LC-6 special application machine has been selected by Küper Transport to create the correct mixture of materials required by Wienerberger AG – the world’s largest producer of bricks – at one of its Dutch plants.

The first stage of the process involves the building of a 200 x 28 x 0.5m stockpile with different materials – such as various types of clay, lava rock and sand – delivered by Küper Transport’s fleet of trucks. The super long front’s superior reach (of 15m) is utilised to scrape and flatten each load into an even layer. Once all of the layers have been prepared, the ZX300LC-6 is then engaged to mix the various types of material to the specification required by Wienerberger to make the bricks.

Moving from one side of the 28m-wide stockpile to the other, the operator, Davey Heimen, skilfully takes 5-10cm from each layer. He scrapes down from the top to the bottom of the pile, before pulling the mixture towards the super long front machine. The bucket is then emptied at an angle to the right of the excavator, so that its tracks can flatten the materials and complete the cycle as it continues to repeat the process and move across the face of the pile.

Founded by current owner Remaldo Küper’s grandfather in 1938, Küper Transport has been working at the Wienerberger factory for more than 40 years. The Spijk-based company bought the ZX300LC-6 super long front with a 1,450-litre chain bucket, extended warranty and a service contract from Hitachi Construction Machinery (Europe) NV’s (HCME) domestic dealer in The Netherlands.

Küper Transport has enjoyed a long-term relationship with HCME, having owned Hitachi machines for 32 years. “Hitachi produces a great excavator with a strong quality/price ratio,” says Remaldo. “In my opinion, anything engineered and manufactured in Japan is perfect, especially when supported by HCME’s excellent maintenance and service here in The Netherlands.”

The primary decision-making criteria determined by Küper Transport for the super long front investment were brand, price and quality. “We considered three machines on this occasion,” adds Remaldo, “but we were immediately impressed by Hitachi’s in-house solution and the lifting capacity of the 15m-reach model.

“We previously used a conventional machine for this project, but some of the materials had to be dug twice as much, which cost us more time, fuel and therefore money. By comparison, we are now able to save 15l per hour and complete our normal cycle 30% faster than before.

“The ZX300LC-6 is the perfect machine for this job. It is stable in these challenging conditions, compact and light, so it’s easy to transport and doesn’t sink into the ground. Hitachi also has a technical advantage over the other brands. The TRIAS II hydraulic system means that only one of the three pumps is used for the swing mechanism. So, when the machine is swinging and lifting, there is no decrease in capacity.”

Operator Davey Heimen is also impressed with the new machine’s suitability: “It’s very smooth and stable, and handles well. This is especially the case when flattening and grading the layers of materials at full reach.

“It’s also faster to complete this task as I can position the machine further back from where the trucks dump the materials than a conventional machine. In addition, I can stay in the same place throughout, because everything I need to do is achievable in one movement.”

“The cab is very comfortable with a heated seat, climate control and an excellent all-round view, which is so important for the precise work that I do. I am also able to save one hour per day with the Hitachi super long front when scraping and mixing the materials.”

A Bulgarian quarry is continuing to run efficiently thanks to the addition of two Hitachi Zaxis-6 excavators and ZW-6 wheel loaders to an expanding fleet of construction machinery. The father and son team at the Plovdiv-based Persenk Invest Ltd (video), Georgi and Ivan Georgiev, bought the ZX350LC-6s and ZW310-6s after the confirmation of a three-year contract with the national government’s power station, starting in September 2017.

The latest Hitachi medium crawler excavators replaced a pair of ZX350LC-3s. The first ZX350LC-6 – and the first Zaxis-6 machine in Bulgaria – arrived at the Kurtovo Konare quarry in April 2017, with the second delivered a year later.

The more recent acquisition moves blasted marble rock from the upper levels of the 100-hectare site on to the quarry floor, where 3,500 tonnes of materials per day are loaded on to the primary crusher by the other ZX350LC-6. The crushed materials are moved by a ZW310-6 (delivered in December 2017) into two piles. They are then loaded periodically on to trucks that dump them into the feeding station for the secondary crushing and screening equipment.

Finally, the other ZW310-6 (delivered in September 2017) loads trucks in the stockyard with the finished products for onward transportation to the power plant (160km away) or other customer sites within a radius of 30km of the quarry. Between 45 and 70 trucks leave the quarry fully loaded twice every day, with 3,000 tonnes being sent to the power station alone.

Having established the company in 2009, Georgi Georgiev decided to buy a Hitachi wheel loader (ZW220) – which the company still owns – and an excavator (ZX280LC-3) in quick succession in 2011. Today Persenk Invest also retains the services of a ZW310 wheel loader and ZX210LC-3 excavator, which in addition to the new machines help to produce 700,000 tonnes of material per annum. The company has a 35-year permit for the site – with an option to extend for a further 15 years – and a strong team of 32 employees, who work in two shifts from 6am to 2pm and 2pm to 11pm.

“Prior to purchasing our machines, we rented three different brands and tested them rigorously, which helped us to decide on Hitachi as the best option,” says Georgi. “We have dealt with the Bulgarian Hitachi dealer Z&M ever since. There is a strong bond between our companies – through trust – and they provide us with an excellent after-sales service.

“It’s about the whole package and Z&M is a reliable partner for our business. This relationship is important to us, and gave us the confidence to invest in new machinery after securing our contract with the power station.”

His son Ivan confirms the importance of fuel economy to Persenk Invest: “The fuel consumption of our new Hitachi machinery is excellent and helps us to significantly reduce our running costs. Both models are the optimum size for us, as they offer complete flexibility for our operations and can therefore deal with any fluctuations in demand – without the need to change the number of employees.”

The operator of the first Zaxis-6 in Bulgaria, Dimitar Georgiev, says, “The ZX350LC-6 is powerful and fast, as well as being easy to operate and enjoyable to work with. It is smoother than the previous model, which means that I am not as tired after a long shift. The cab is also very comfortable and quiet – the best thing about this high-quality machine. It is perfect: stable, strong and well suited to the demands of a quarrying environment.”

Wheel loader operator Stoycho Guglev adds: “The ZW310-6 is very fast for moving between the stockpiles and even more productive than the previous model. The joystick is effortless for steering, as well as being smooth to operate and easy to control the machine. Loading is straightforward thanks to the traction force associated with the LSD (limited slip differential). The most impressive feature is the comfort in the cab, with ample space and a lack of noise.”

AC Stolwerk Sloopwerken BV has purchased the first Hitachi Premium Used excavator to work on a wide range of projects in the vicinity of Breda, in the province of North Brabant, The Netherlands. The demolition and recycling firm, which also specialises in the removal of asbestos, purchased the ZX350LC-5 (video) due to the favourable costs associated with the machine and the excellent coverage provided by the warranty included within the Premium Used package.

Established in 1953, Stolwerk has had a long and successful working relationship with Hitachi Construction Machinery (Europe) NV (HCME) spanning four decades. It also has three other Hitachi excavators (a ZX470LCH-3 and two ZX210W-3s) at its disposal, for which it has always received a high level of technical support from HCME’s domestic dealer.

Owner Thierry Stolwerk – the third generation of the family to run the business – bought the Hitachi Premium Used ZX350LC-5 to load the company’s mobile crusher, which is utilised to recycle demolished materials. However, Stolwerk is so busy that the versatile machine has also been commandeered for other projects since it was delivered at the end of 2017, such as its first job on the site of an old factory that was originally built in the 1920s on Speelhuislaan in Breda.

After deciding on the ZX350LC-5 as the most appropriate machine for the capacity of the crusher, Stolwerk then considered the benefits of purchasing a model with 3,000 working hours through the Hitachi Premium Used programme. “When I was offered the guarantee of a high-quality machine with an approved Hitachi warranty, I had to assess how this would benefit our company’s operation.

“The price of a used machine was obviously advantageous and offered a 36% saving over a new model. In addition to the advantage of having less depreciation, I also had the peace of mind of fixed running costs from the maintenance contract.

“When I inspected the machine for the first time, I could feel the quality of a fully serviced machine – it was like new! I was also impressed that HCME was able to deliver the machine within a week, complete with a quick hitch, which is essential for the number of attachments we use in our demolition business.

“I would have no hesitation in buying another Hitachi Premium Used machine, as there may be an opportunity to do so in the future with one of our wheeled excavators. As well as the high level of service we receive from HCME, I also consider the fuel consumption of our machines to be a top priority and the ZX350LC-5 also ticks this box with distinction.”

Stolwerk’s experienced operator, Cees Diepstraten, who has been with the company for 25 years, says, “While you would still know that it’s a used machine, the ZX350LC-5 was delivered in immaculate condition by HCME.

“On this site, I use it for sorting the demolished materials and loading our trucks with piles of rubble, wood and metal. The machine is very stable for working with such heavy materials, and the spacious and comfortable cab allows me to have a good view of what I’m doing.”
