World bridge crane hoisting success

On November 22, Yantai Raffles Offshore Engineering Co., Ltd., a subsidiary of CIMC Group (000039), held a ceremony for hoisting the 20000-ton bridge crane "Taishan" and closing the 14,000-ton deck module of the semi-submersible oil drilling platform of COSCO. Mai Boliang, president of CIMC Group and chairman of the board of directors of Raffles, said that the successful hoisting has created a new mode of offshore engineering construction, and CIMC is full of confidence in the future prospects of Raffles. According to reports, the "Taishan" 20000-ton bridge crane, with a crane design lifting weight of 20160 tons, is currently the world's large lifting weight, large span, and large lifting height bridge lifting equipment, and it is also technically difficult in the world today. Large-scale lifting equipment, there has not been lifting equipment with a lifting weight of more than 10,000 tons at home and abroad before. "Taishan" can lift a full-load barge weighing up to 20133 tons, setting a Guinness World Record for the large lifting capacity of bridge cranes. The successful operation of this equipment has changed the traditional construction method of offshore oil drilling platforms, and realized the construction mode of parallel construction of semi-submersible platforms and one-step closing through a 20000-ton crane, so that the construction time of each semi-submersible drilling platform can be saved. 2 million man-hours, shorten the ship construction cycle by more than 30%, and improve the construction quality, production efficiency and construction safety. The semi-submersible oil drilling platform hoisted this time is the first ship of three fourth-generation semi-submersible drilling platforms built by Yantai Raffles for CNOOC (601808).

4 trillion Stimulus Plan Construction Machinery Industry First Benefit

The ten measures to expand domestic demand and promote economic growth determined at the recent executive meeting of the State Council are expected to require an investment of about 4 trillion billion yuan by the end of 2010. The positive effect of the policy on steel, cement, railway, infrastructure and other industries is self-evident. For the majority of small and medium-sized enterprises, although there are not many direct beneficiaries, they also benefit indirectly due to the transformation of value-added tax and the boost of domestic demand. The construction machinery industry is the first to benefit from the implementation of the economic stimulus plan, the majority of small and medium-sized enterprises are expected to benefit indirectly. Construction machinery companies have attracted much attention. Industry insiders predict that the 4 trillion stimulus policy will make engineering

Prospect Analysis of Data Cable Replacing Security Video Surveillance Cable

A set of installation and debugging, the construction of a good video security system is used to produce or process high-quality video cameras, lenses, monitors, video recorders, but if there is no good transmission system, the final image on the monitor will not be satisfactory to achieve the ideal state of the device. According to the "barrel rule", the final image quality will depend on the worst part of the whole system; and the worst part is often the data transmission system. System designers and installers must choose the appropriate transmission mode, high-quality transmission cables and equipment according to actual needs, and install them according to professional standards in order to achieve the ideal transmission effect.

About the classification and model of monitoring common cable

Video line, radio frequency line, shielded and unshielded, signal line, control line, etc., various models, newcomers are often confused. The following are the differences between several commonly used models: RVV and KVVRVVP and KVVP. The line used in RVV and RVVP is a flexible line composed of multiple strands of thin copper wire, that is, RV wire. The line used in KVV and KVVP is a hard line composed of a single thick copper wire, that is, BV wire. The difference between AVVR and RVVP: the same thing, except that the name of the internal section less than 0.75 mm² is AVVR, and the name of the 0.75 mm² greater than or equal

Building intercom system layout control cable purchase and use recommendations

At present, the connecting cables used in building intercom systems on the market are mostly signal control lines (such as PVC sheathed flexible wire RVV and shielded wire RVVP) and coaxial SYV-75 series cables. The requirements of the system for cables are to transmit signals such as voice, data and video. At the same time, the requirements for cables are also reflected in the quality of voice transmission, the rate of data transmission, the quality and rate of video signal transmission, etc. In building visual intercom systems, the quality requirements for connecting cables are quite high. The cables for transmitting voice signals and alarm signals mainly use 4-core PVC sheathed flexible cords (RVV).

A brief analysis of the requirements of security cables in the access control system

In recent years, with the rapid progress of science and technology, the information industry has also been booming, and wire and cable is the blood vessel of the industry, so the demand for wire and cable products is also increasing. In fact, new wire and cable products have indeed sprung up, showing their skills in various emerging high-tech industries, such as communication cables, security cables, and fire cables. It is reported that the annual growth rate of the cable market is about 8%-12%, of which the growth rate of security cables is particularly eye-catching. Although China's security cable industry has some problems, such as late start, backward technical equipment, etc., its growth rate can

Network Expansion Failure Caused by Stale Cables

With the continuous popularization of network applications and the continuous expansion of the scale of the unit, many LAN networks that have been established for a long time have almost all the needs of upgrading and expansion. In order to save the cost of network upgrade as much as possible, many network administrators often make full use of some old equipment and old cables that are in normal working condition when expanding the network, so as to make the best use of everything. However, in the case of retaining old equipment and old cables, network expansion is prone to some unexpected failures. This is not, a network expansion failure listed below in this article is caused by retaining an old network cable, considering
