Purposes & Features
Cookies, device or similar online identifiers (e.g. login-based identifiers, randomly assigned identifiers, network based identifiers) together with other information (e.g. browser type and information, language, screen size, supported technologies etc.) can be stored or read on your device to recognise it each time it connects to an app or to a website, for one or several of the purposes presented here.
Most purposes explained in this notice rely on the storage or accessing of information from your device when you use an app or visit a website. For example, a vendor or publisher might need to store a cookie on your device during your first visit on a website, to be able to recognise your device during your next visits (by accessing this cookie each time).

Advertising presented to you on this service can be based on limited data, such as the website or app you are using, your non-precise location, your device type or which content you are (or have been) interacting with (for example, to limit the number of times an ad is presented to you).
A car manufacturer wants to promote its electric vehicles to environmentally conscious users living in the city after office hours. The advertising is presented on a page with related content (such as an article on climate change actions) after 6:30 p.m. to users whose non-precise location suggests that they are in an urban zone.
A large producer of watercolour paints wants to carry out an online advertising campaign for its latest watercolour range, diversifying its audience to reach as many amateur and professional artists as possible and avoiding showing the ad next to mismatched content (for instance, articles about how to paint your house). The number of times that the ad has been presented to you is detected and limited, to avoid presenting it too often.
4
Information about your activity on this service (such as forms you submit, content you look at) can be stored and combined with other information about you (for example, information from your previous activity on this service and other websites or apps) or similar users. This is then used to build or improve a profile about you (that might include possible interests and personal aspects). Your profile can be used (also later) to present advertising that appears more relevant based on your possible interests by this and other entities.
If you read several articles about the best bike accessories to buy, this information could be used to create a profile about your interest in bike accessories. Such a profile may be used or improved later on, on the same or a different website or app to present you with advertising for a particular bike accessory brand. If you also look at a configurator for a vehicle on a luxury car manufacturer website, this information could be combined with your interest in bikes to refine your profile and make an assumption that you are interested in luxury cycling gear.
An apparel company wishes to promote its new line of high-end baby clothes. It gets in touch with an agency that has a network of clients with high income customers (such as high-end supermarkets) and asks the agency to create profiles of young parents or couples who can be assumed to be wealthy and to have a new child, so that these can later be used to present advertising within partner apps based on those profiles.

Advertising presented to you on this service can be based on your advertising profiles, which can reflect your activity on this service or other websites or apps (like the forms you submit, content you look at), possible interests and personal aspects.
An online retailer wants to advertise a limited sale on running shoes. It wants to target advertising to users who previously looked at running shoes on its mobile app. Tracking technologies might be used to recognise that you have previously used the mobile app to consult running shoes, in order to present you with the corresponding advertisement on the app.
A profile created for personalised advertising in relation to a person having searched for bike accessories on a website can be used to present the relevant advertisement for bike accessories on a mobile app of another organisation.

Information about your activity on this service (for instance, forms you submit, non-advertising content you look at) can be stored and combined with other information about you (such as your previous activity on this service or other websites or apps) or similar users. This is then used to build or improve a profile about you (which might for example include possible interests and personal aspects). Your profile can be used (also later) to present content that appears more relevant based on your possible interests, such as by adapting the order in which content is shown to you, so that it is even easier for you to find content that matches your interests.
You read several articles on how to build a treehouse on a social media platform. This information might be added to a profile to mark your interest in content related to outdoors as well as do-it-yourself guides (with the objective of allowing the personalisation of content, so that for example you are presented with more blog posts and articles on treehouses and wood cabins in the future).
You have viewed three videos on space exploration across different TV apps. An unrelated news platform with which you have had no contact builds a profile based on that viewing behaviour, marking space exploration as a topic of possible interest for other videos.

You read articles on vegetarian food on a social media platform and then use the cooking app of an unrelated company. The profile built about you on the social media platform will be used to present you vegetarian recipes on the welcome screen of the cooking app.
You have viewed three videos about rowing across different websites. An unrelated video sharing platform will recommend five other videos on rowing that may be of interest to you when you use your TV app, based on a profile built about you when you visited those different websites to watch online videos.

Information regarding which advertising is presented to you and how you interact with it can be used to determine how well an advert has worked for you or other users and whether the goals of the advertising were reached. For instance, whether you saw an ad, whether you clicked on it, whether it led you to buy a product or visit a website, etc. This is very helpful to understand the relevance of advertising campaigns.
You have clicked on an advertisement about a “black Friday” discount by an online shop on the website of a publisher and purchased a product. Your click will be linked to this purchase. Your interaction and that of other users will be measured to know how many clicks on the ad led to a purchase.
You are one of very few to have clicked on an advertisement about an “international appreciation day” discount by an online gift shop within the app of a publisher. The publisher wants to have reports to understand how often a specific ad placement within the app, and notably the “international appreciation day” ad, has been viewed or clicked by you and other users, in order to help the publisher and its partners (such as agencies) optimise ad placements.
4
Information regarding which content is presented to you and how you interact with it can be used to determine whether the (non-advertising) content e.g. reached its intended audience and matched your interests. For instance, whether you read an article, watch a video, listen to a podcast or look at a product description, how long you spent on this service and the web pages you visit etc. This is very helpful to understand the relevance of (non-advertising) content that is shown to you.
You have read a blog post about hiking on a mobile app of a publisher and followed a link to a recommended and related post. Your interactions will be recorded as showing that the initial hiking post was useful to you and that it was successful in interesting you in the related post. This will be measured to know whether to produce more posts on hiking in the future and where to place them on the home screen of the mobile app.
You were presented a video on fashion trends, but you and several other users stopped watching after 30 seconds. This information is then used to evaluate the right length of future videos on fashion trends.
0
Reports can be generated based on the combination of data sets (like user profiles, statistics, market research, analytics data) regarding your interactions and those of other users with advertising or (non-advertising) content to identify common characteristics (for instance, to determine which target audiences are more receptive to an ad campaign or to certain contents).
The owner of an online bookstore wants commercial reporting showing the proportion of visitors who consulted and left its site without buying, or consulted and bought the last celebrity autobiography of the month, as well as the average age and the male/female distribution of each category. Data relating to your navigation on its site and to your personal characteristics is then used and combined with other such data to produce these statistics.
An advertiser wants to better understand the type of audience interacting with its adverts. It calls upon a research institute to compare the characteristics of users who interacted with the ad with typical attributes of users of similar platforms, across different devices. This comparison reveals to the advertiser that its ad audience is mainly accessing the adverts through mobile devices and is likely in the 45-60 age range.

Afgelopen jaar bestond Liebherr 70 jaar. In datzelfde jaar introduceerde het Duitse familiebedrijf de 8e generatie van de R-serie rupsgraafmachines.
De basis van het tegenwoordig omvangrijke familiebedrijf dat actief is in verschillende sectoren, werd in 1949 gelegd door Hans Liebherr. In de naoorlogse tijd bemerkt de zoon van een Zuid-Duitse aannemer de grote behoefte aan (bouw) machines en ontwikkelt hij de TK 10 mobiele torenkraan. In datzelfde jaar is de eerste Liebherr Maschinenfabrik in Kirchdorf een feit.
Begin de jaren vijftig van de vorige eeuw huurt Liebherr een mobiele graafmachine en daarbij valt hem op wat voor een slechte verhouding de machine heeft tussen gewicht en vermogen. Slechts acht maanden later introduceert hij in 1954 de Liebherr L300 mobiele graafmachine die vier keer lichter is dan de huurmachine. In datzelfde jaar ziet de zakenman overigens ook grote kansen op de consumentenmarkt voor koelkasten, en in plaats van het overnemen van een te koop staande fabriek, bouwt hij een eigen fabriek voor de productie van Liebherr-koelkasten.
Start rupsgraafmachines
Van de eerder genoemde L300-graafmachine verscheen medio jaren vijftig ook een variant voor vrachtauto’s én, een versie op rupsen met de aanduiding R. In 1960 komt de RT1000 op de markt, een rupsgraafmachine van 20 ton en daarmee de grootste Liebherr. In 1961 bouwt de fabrikant een fabriek voor rupsgraafmachines in Colmar in de Franse Elzas. Daar produceerde het afgelopen jaar de 60.000e rupsgraafmachine, een R 922, met dus ongeveer hetzelfde operationele gewicht als de RT1000. In 1968 legt Liebherr de basis voor de huidige R 900-serie.
In 1960 komt deze RT1000 op de markt, een rupsgraafmachine van 20 ton en daarmee de grootste van Liebherr op dat moment.
De allereerste graafmachine van Liebherr in 1954: de L300. Deze was vier keer lichter dan de gehuurde machine die Hans Liebherr aanzette tot de ontwikkeling ervan.
Op de Bauma van 2019 introduceerde de fabrikant de huidige generatie R 900 die zijn voorganger, de zevende generatie, uit 2013 afloste. Daarbij waren de R 922 en R 924 de debutanten met gewichten van 22 en 24 ton. De overstap naar fase 5 motorisering, natuurlijk Liebherr-motoren, greep het merk aan om de achtste generatie van de R 900-serie te introduceren. Vanzelfsprekend wijzigde er veel meer dan enkel de motorisering.
De modellen van de achtste generatie vervangen de oude modellen uit 2013 die nog zijn uitgerust met een Stage IIIB motor. De nieuwe R 922 en R 924 zijn voorzien van een Liebherr-motor die voldoet aan de emissie-eisen van Stage V. Afgelopen jaar kwamen eveneens de nieuwe R 926, R 930, R 934, R 938 en R 945 op de markt.
In de in 1961 opgerichte fabriek in Colmar produceerde Liebherr afgelopen jaar de 60.000e rupsgraafmachine: deze R 922
Compacte klasse
Onder de 22-tons en in de compacte klasse vonden in de tussentijd wel diverse ontwikkelingen plaats. Zo kwam in 2017 de nieuwe R 918 op de markt met fase 4 120 kW/ 163 pk motor. Uitlaatgasmaatregelen zijn er in de vorm van DOC en SCR (AdBlue) met optioneel een roetpartikelfilter. In 2018 zet de nieuwe R 926 Compact de productlijn met compacte modellen voort met een fase 4 129 kW / 175 pk motor. Deze Liebherr motor kan zonder EGR-klep en roetpartikelfilter toe.
Door middel van één grote kap is alles meteen bereikbaar voor eventueel onderhoud.
Nieuwe hydraulische componenten in de R 926 Compact garanderen volgens Liebherr een productiviteitsverhoging ten opzichte van het eerdere model. Het verbeterde zwenkmoment van de bovenwagen is 84 kNm, een toename van 18 % procent ten opzichte van z’n voorganger.

Terug naar de generatie 8 modellen. Kenmerkend voor deze generatie zijn volgens de fabrikant betere prestaties, een hogere productiviteit bij een lager brandstofverbruik en meer veiligheid en comfort voor de machinist. Aan de buitenkant valt vooral het nieuwe ontwerp op. Volgens Liebherr heeft het team van ontwikkelaars het basisconcept volledig herzien om het comfort, de veiligheid en de prestaties verder te verhogen en om een nog betere ergonomie tijdens het gebruik te bereiken. De graaf- en trekkrachten van het onderstel en het zwenkkoppel van de bovenwagen zijn aanzienlijk toegenomen in vergelijking met de vorige generatie.
Kenmerkend voor de generatie 8 modellen zijn volgens de fabrikant betere prestaties, een hogere productiviteit bij een lager brandstofverbruik en meer veiligheid en comfort voor de machinist.
De modellen zijn verkrijgbaar met verschillende, robuuste, X-vormige onderwagentypen, waaronder een nieuwe WLC-onderwagen, die de hoge stabiliteit garandeert die vereist is voor bijzonder zwaar gebruik. Het rupsonderstel is volledig onderhoudsvrij en de looprollen zijn voorzien van permanente smering.
In de cabine beschik je als machinist over ruim bedieningsgemak en -comfort inclusief een 7 inch touchscreen display met hoge resolutie. Af fabriek kun je kiezen voor voorbereiding voor Trimble 3D-gps machinebesturing. In de schemering en in het donker heb je gemak van de ledlampen die de halogeenkoplampen volledig vervangen. Er zijn verschillende ‘verlichtingpakketten’, zoals het optionele led+ verlichtingspakket voor optimaal zicht op het werk.
Het 7 inch touchscreen display van in dit geval de Liebherr R 926 Compact, biedt de machinist optimale instellings-, bewakings- en bedieningsopties.
De huidige R 900-serie is enorm omvangrijk en loopt van de:
R 914 Compact met 14,9 – 17,8 ton, 0,80 m3 laadvermogen en 90 kW / 122 pk tot de R 936 Compact met 33,8 – 38,3 ton, 1,75 m3 laadvermogen en 190 kW / 258 pk
R 918 met 19,6 – 22,7 ton, 1,15 m3 laadvermogen en 120 kW / 163 pk tot de R 980 SME met maar liefst 95,9 – 101,2 ton, 7,2 m3 laadvermogen en 420 kW / 571 pk
Door het lage zwaartepunt is de machine toch stabiel.
Grondwerken Tops & Zoon (Putte)
Grondwerken Tops & Zoon uit het Mechelse is vooral actief in de industriebouw en de rioleringen. Hiervoor kocht het bedrijf een Liebherr 920 Compact. “Door zijn compacte bouw is de machine niet breder dan 3 meter. Dit gaf de doorslag bij de aankoop van de machine.” Toch biedt de graafmachine meer dan genoeg ruimte in de cabine en is ze stabiel door het lage zwaartepunt. “Het enige nadeel aan de machine is de plaatsing van een stuk van de motor naast de cabine. Als iemand in de gracht staat en je wil er iets tegen zeggen, verhindert dit toch de communicatie.” Naast het stevige hefvermogen is de kraan ook goed geschikt voor het nivelleren. Hiervoor installeerde het bedrijf een 3D-systeem. Voorlopig ligt het verbruik gemiddeld op 9,5 liter per uur.
Thomas, machinist van de Liebherr R920 Compact en medezaakvoerder, koos voor deze graafmachine door zijn compacte bouw waardoor zijn machine niet breder is dan 3 meter
