Bechtel has pioneered customized web applications with M2M data for individual workers atmammoth construction machinery projects involving millions of pieces of data. The data flows from its enterprise software systems and devices and brokered by cloud-hosted APIs for selective streaming to workers, who use web applications on iPads to view information useful to them. For example, Bechtel embeds sensors in wet concrete to monitor its curing.

"Rich analytics, such as productivity of resource use on a construction site, becomes possible when data flows from a diversity of databases and devices with input and output information," Ed Anuff, vice president of product strategy, at Apigee (which works with Bechtel), told me. "Most companies were not built with APIs in mind, and the integration of their information happens with help from the Apigee aerial work platform. As enterprises use a growing array of mobile devices, API usage inevitably grows as a way to have them talk to each other."

The UK company SQLstream has developed a dynamic street light adjustment application that will be launched soon in Australia. Instead of changing at fixed intervals, traffic lights will be prompted to switch with the ebb and flow of traffic at crossroads. The application has been developed in collaboration with Oracle, which brings its Smart City platform, and C-Track, a vendor that specializes in vehicle movement monitoring.

SQLstream's s-transport analytical engine, sitting in the cloud, accesses C-Track data with APIs and determines the traffic density and the appropriate timing of lights at each turn, while synchronizing with all the other signs in the network. "The process starts with a lightweight API adapter to extract data, the analytics engine integrates the data streams without storing them and then feeds reports to operational systems and depicts them visually on dashboards in cars for individual drivers," Ronnie Beggs, vice president of marketing at SQLstream, told me. ]]> https://ameblo.jp/jonlee24565/entry-11799103230.html Tue, 18 Mar 2014 17:50:05 +0900 mobile crane on a five-axle chassis. Compared to its predecessor, the LTM 1160-5.1, the LTM 1160-5.2 has a 20-25% increase in load capacity even though it uses the same 203-ft. telescopic boom. Vehicle width has been reduced from 9’10’’ to 9’0”, which makes it easier to drive on public roads and through constricted sites.

One of the most notable features on the LTM 1160-5.2 is that the superstructure is powered by a single engine in the crane chassis using a mechanical shaft, rather than the twin-engine concept normally used on cranes in this class. This is the second five-axle crane model to feature the single-engine drive concept, which Liebherr first presented at Bauma 2013 on the LTM 1300-6.2.

Gear shafts are routed from the distributor gear in the crane chassis via two mitre gears through the center of the slewing ring to the pump distributor gear in the superstructure.

A Tier 4 Final, six-cylinder Liebherr diesel engine develops 544 hp at 1900 rpm and torque of 2,516 Nm at 1350 rpm. Force is transferred to the crane axles via the 12-speed ZF-AS Tronic gears. The intarder, a zero-wear hydrodynamic brake integrated in the gearbox, acts as a retarder. In addition a Telma eddy current brake is available as an option.

The mechanical shaft ensures a high efficiency level, and low engine speeds in the chassis engine provide sufficient power for crane work. Benefits of removing the separate superstructure engine include reducer maintenance work and weight. The omitted weight can be used for load-bearing components, thus increasing the crane’s load capacity. ]]> https://ameblo.jp/jonlee24565/entry-11799100649.html Tue, 18 Mar 2014 17:45:03 +0900 construction machinery industry is extremely competitive, especially international construction machinery giant inroads into the Chinese market , such as Caterpillar , Komatsu and so on.

Manufacturers and dealers are not confident enough , lifting machinery in 2013 the only small peak in October , the fourth quarter smooth peripheral investment environment, the decline in real estate and infrastructure to maintain the status .
As a five-year plan to implement the key objectives of the year 2013 , the country's economic development in an important period of strategic opportunities . Urbanization, industrialization, internationalization of construction have entered a critical stage . Construction crane companies are beginning to rational analysis of the main reason for the market downturn of the industry , after bitter experience, confidence, seek effective development path.
From a macro perspective, in 2014 , the railway investment priorities for the Midwest and intercity rail , funds will gradually be guaranteed ; total road investment remains low, but the West is still the focus of investment ; nuclear power has to pick up the trend , and from the target values ​​are far away , investment growth in the next two years a larger space ; public service investment opportunities appear, due attention. As the domestic economic environment and stabilize the downstream industry as a whole , in 2014 the construction machinery industry fundamentals improved slightly , but hardly rebounded significantly. 2014 will face a slowdown, the structure is more differentiated economic environment , fixed investment will show a trend of low to high before .
According to Zoomlion Group research director Li strategic analysis and forecasting at the annual meeting of the crane branch : Based on the overall situation in the downstream changes that may occur in 2014 and the macroeconomic environment , the cranes will continue to narrow the overall decline , the sub- products may significantly differentiation . 2014 new aircraft sales pulling power will be weak ; truck crane domestic demand grew 12% , exports grew by 7.1% ; crawler crane domestic demand is expected to increase 1.9%. ]]> https://ameblo.jp/jonlee24565/entry-11798328092.html Mon, 17 Mar 2014 17:41:24 +0900 2) harmonic harmonic drive reducer is the use of the elastic deformation of the flexible element to deliver a controlled motion and power, small size, high precision, but the drawback is the limited flexible wheel life, the impact of intolerance, rigidity and metal parts compared to the poor. Input speed is not too high.
3) the advantage of planetary gear structure is compact, small backlash, high precision, long life, rated output torque can do a lot. But the price is a little expensive.
Reducer:

Briefly, the general design and power of the machine manufactured, its rated power does not change, then, the greater the speed, the torque (or torque) is smaller; speed is smaller, the greater the torque.

A : We all want to know when the upper and lower overhead crane hook operation , inseparable stopper. Because the bridge crane hook operation is controlled by the stopper . So when we usually work to carefully check whether the stopper fitting sticking together. If the stopper fitting stick together when the hook rising role stopper invalid. However, the hook is constantly on the rise, the rope will withstand the shock pressure , the occurrence of fracture. In the end, leading to falling cargo could cause casualties.

II: aging crane when staff did not conduct regular maintenance and testing . When the case was the failure of the stopper hide , then personnel when operating the crane hoisting occurs .

Three: When staff installed cranes , falling and rising chaos if the operation of the crane operator due to urgent circumstances forget to use the emergency lane switch will appear hoisting phenomenon . ]]> https://ameblo.jp/jonlee24565/entry-11796011325.html Fri, 14 Mar 2014 16:21:31 +0900
A first was the order for the new LiSIM mobile harbour crane simulator for Saqr Port in Ras Al Kaimah, United Arab Emirates. The resulting increase in operator skills allows for safe and productive crane operation in the real world and naturally boosts productivity. Saqr Port has opted for the classroom solution which can be easily integrated into existing training centres.

Saqr Port has ordered an LHM 550, reinforcing its existing mobile crane fleet. The new crane is equipped with Liebherr’s Pactronic system for more fuel efficient bulk handling. The LHMs can also be used for container handling and general cargo operation if necessary – just by an easy exchange of the lifting attachment. The new crane and simulator will be commissioned in the first quarter of 2014.

To revitalise the Port of Maqal in Iraq, NAWAH Port Management has purchased an LHM 180 and a Liebherr LRS 645 Reachstacker. The LHM 180 is designed for container handling as well as for safe and reliable general cargo operation having a maximum lift of 64 tonnes. ]]> https://ameblo.jp/jonlee24565/entry-11795233771.html Thu, 13 Mar 2014 17:38:30 +0900 Foundry & Steel Manufacturing

Just like in the car business, there will always be some forklift dealerships and dealer sales people that either don’t have enough experience, training or desire to do the right thing when it comes to selling used forklifts so proper due diligence is very important, otherwise you might just get stuck with a lemon.
In the forklift business, this issue is further magnified because forklifts are more likely to be damaged during normal operation, particularly if they have been used by abusive operators. To the untrained eye, much of this damage will be missed during inspection.
Forklift repairs are much more expensive than car repairs so it is very important to catch these repairs before you commit to a purchase. Fleetman can help steer you in the right direction and can protect you from these types of used forklift problems before you buy. ]]> https://ameblo.jp/jonlee24565/entry-11795229917.html Thu, 13 Mar 2014 17:36:13 +0900
