Best Qualities of a Crawler Excavator

imagesIt is difficult to overestimate the significance of a crawler excavator in the category of construction machinery. This multifunctional vehicle can boast numerous special features. The first and foremost merit is the chassis with tracks that are made up of flat link chains. They provide the high level of cross-country mobility, which is so valuable on construction sites. Another factor, contributive to wide practical applicability, is the flexible configuration. The options are available in the choice of the basis and attachments.

A wide range of advantages generates strong demand for tracked excavators. Consequently, its production rates have reached a prominent percentage in the global market. And it’s reasonable that the market is highly competitive.

It is common knowledge that all virtues need to be taken care of. To get the best of a crawler excavator one should take into account some operating limitations. As there are high risks to damage the coat by the tracks, it is not allowed to drive these vehicles on the topcoat asphalt. Long-distance runs are also undesirable in order not to accelerate the depreciation process, resulting in efficiency loss.

To attain all the benefits a crawler type of excavators is capable of, it should be carefully chosen according to the future operating tasks. The choice also requires considering the peculiarities of the ground. These factors in turn influence the selection of the necessary dimensions of a vehicle and its attachments.

In space limited areas there is a possibility to use a compact version of a crawler excavator, also known as a mini-excavator. Thanks to a lower machine weight, such models can be easily moved between different sites.

As for specifically designed crawler excavators, amphibious and bucket-wheel models are worth mentioning. The structures of both of them involve only tracked versions.

An amphibious excavator is made to perform dredging while afloat in shallow water. The tracked chassis floats on sealed pontoons that are manufactured from high tension steel, invulnerable to saltwater and corrosion. The pontoon tracks are powered by a vehicle’s engine and main hydraulic pumps with traveling motors.

Bucket-wheel excavators are used as mobile strip mining machines. Their primary purpose is to remove overburden prior to coal mining. This kind of self-moving machine is one of the largest and heaviest land vehicles ever built. To allow the ground not to settle under such a considerable weight (about 13.000 t), the excavator features a dozen of 3.8-meter tracks. As a result, the pressure, exerted on the ground, doesn’t exceed the one, exerted by human’s feet.

Top 5 Qualities Of A Good Driving School

assTrained and qualified drivers are very important on the roads because they have the necessary skills to drive safe and keep avoidable accidents minimal. Driving may look like a very simple thing to do, but there are so many things that need to play out for the roads to be safe enough. The driving school you choose for your driving classes can determine how qualified and ready you are for the road by the time your course is over. To be the best you must train with the best and there are qualities that every driving school should have to produce exceptional drivers.

1. Fully equipped facility – This is one of the most important qualities of a driving school because without the necessary materials, it would be impossible to complete the course and tests. A good driving school should be up to date with the latest technology and have the relevant training materials. It should also have a designated area where learners can navigate as they practice what has been taught in class.

2. Professional instructors – It is one thing to have all materials needed for the classes and quite another not to have qualified instructors to guide the learners through. A good driving school is one that has a combination of good facilities and professional instructors. The instructors should focus more on an engaging learning process so they students have a sense of responsibility in getting the knowledge that they need to become excellent drivers.

3. Comprehensive driving lessons – The best driving lessons should touch on theory, skills training and proper practical driving test. Theory tests help learners assess knowledge of lessons taught and help the instructors analyze everything before going to the next stage. Skills training is also very important because it gives the learners a chance to hone their skills, especially when it comes to driving maneuvers; it prepares them for the actual driving test that will fetch successful learners their licenses. With the comprehensive lessons, by the time leaners get to practical driving test, they are ready and confident and have increased chances of being successful.

4. Flexible lesson timings – Leaners are not always available all at the same time and it is up to the driving schools to create lesson schedules that match with the students’ availability. Good driving schools create slots in different times during the day so that all interested learners are able to learn when it is most convenient for them. Flexible lessons and a team of instructors ensure that no learner has to wait too long before completing their driving courses.

5. Reasonable pricing – Top notch driving lessons do not always translate into high prices. Whereas it is not expected that a good driving school with the right materials will offer very cheap driving lessons, the pricing for the same should be nominal so that all interested learners can benefit from the services offered. There are various factors that can affect the pricing for the lessons, but you should ensure that you get the most reasonable rates.

Car Umbrella – An Extra Layer of Protection

gThe car is an invaluable tool for many of us. In order to minimize the effects of the elements on the cars, a product called the Car Umbrella was developed. By adding a barrier between your car and the elements, it lessens the toll your steel horse takes over the years.

In essence, the car umbrella is a cover that extends over your vehicle so that you can leave your car or stay inside when the weather is less than optimal. By extending a protective canvas, which consists of a material similar to the one used for boats’ sails, over the whole roof of the car, the umbrella safeguards it from weather conditions, such as the sun, acidic rains, leaves, dust particles or, least savory of all, bird droppings. Be advised, it is intended for use only when not driving.

The invention itself is user-friendly. Uniquely designed, it is intended for ease of use and to be polyvalent. It is made out of high-quality materials, such as copper anti-rust windproof snaps and military grade fiberglass rods. In addition, the snaps will disengage to protect the integrity of the installation in case of strong winds. The Umbrella itself is mounted on suction cups, to be installed in the middle of the car roof. With 70 kg of horizontal suction and wind ropes to protect against gusts, it makes the whole installation quite stable. All the pieces in contact with the car are made of soft materials to ensure that they do not scratch the car’s paint. Add into the mix high-quality polycarbonate fittings and a battery that operates for a full month after one charge, and this isn’t merely a simple contraption.

Installing it, on the other hand, takes a mere 30 seconds. Its canvas, 2.1 meters wide by 4 meters, can then be deployed in less than 10 seconds, using the remote which is effective up to 98 ft. (almost 30 meters) away. When its arms are extending, one is reminded of a bat spreading its wings. For storage, it can easily fit in any trunk and be carried and deployed as needed as it is only 85 cm long. You also have the option of 3 different color schemes for the canvas cover, allowing you to customize the Umbrella to fit whatever mood you’re in.

The way we see it, it provides two advantages to your car. On the one hand, it protects the outside and lessens the upkeep. Secondly, it generates an airflow and separation between the car and its surroundings. This translates into significantly lower car surface temperatures in sunny conditions, in some cases as much as 35oC, and consequently cooler temperatures inside. That way you can save on fuel if you decide to wait in the car, since the air-conditioning will not be as important, and your car will suffer much less wear and tear while it’s left parked in nature or underground parking lots.

The Lamborghini Elemento – An Engineering Marvel

asA pure masterpiece in design and a supercar that has been taking it to the extreme. “Sesto Elemento” means “the six element” and refers to the atomic number if carbon, due to the significant amount of carbon in the production of this vehicle.

When it comes to the design the Lamborghini Sesto Elemento is truly one of its kind. The all wheel drive, 6-speed semi automatic paddle shift is paired with a 5.2 litre V10 engine generating 570 horsepower @ 8000 rpm and about 400 ft/lbs of torque @ 6500 rpm. What makes this car truly unique is the chassis, body, driveshaft and suspension components are all made of carbon fiber reducing the overall weight to a mere 999 kilograms (2,202 lbs), a comparable weight to subcompact cars. This gives the Lamborghini Sesto Elemento a very strong power to weight ratio. Lamborghini claims that the Lamborghini Elemento has an acceleration time of 0-62 mph (0-100km/h) in just 2.5 seconds.

As for the interior, Lamborghini kept it simple with this one. It has only the basic comforts such as air-car stereo and air-conditioning. There are no actual seats in the Lamborghini Elemento. The shape of the interior runs with the body of the car, with pads set in the carbon fiber tub. This not only reduces weight (which was the main objective with this car) but also give the driver and real sense of the road, feeling everything the car feels.

Lamborghini teamed up with the Boeing company to perfect the design of the Lamborghini Elemento. Almost every single panel on the exterior was made from carbon fiber. The wheels are completely made of carbon fiber and the exhaust system is made of Pyrosic (a headproof glass material). And as if that wasn’t enough, there is a racing-type quick-refueling system. The rear end is open, giving a clear view of the transmission and Pyrosic exhaust system.

Performance

This sensational car, with its 5.2 L V10 engine allows 5,204cm3 of displacement, with 80.5 kW per liter. The air is released through 10 different holes in the engine cover, and cool air is funneled by two intakes into the mid mounted engine compartment.
