Large Transportation
Jan 22, 2020 News
– Transportation of parts of turbines and generators of high degree of prefabrication in the construction and repair of power stations. Forestry – timber transportation from cutting areas to places of processing. Construction – Transportation large concrete structures, particularly in the management of construction in remote areas. – Transportation of construction of farms, farms, and willing to bridge spans – Transportation of pre-engineered buildings (flats, sections) to build on-site principle cubes Large cargo is easy to see most of the suggestions apply to the transport of oversized and heavy cargo (CTG), especially in areas limited accessibility. The need for transportation ctg is attributable to a significant economic effect of the delivery structures of high degree of prefabrication to the industrial and energy facilities. Escalation of packages allows you to create one or the other industrial complex on the "modular" principle. Taking into account the transportation costs, even other modes of transport, not airships, the savings in such an approach can reach 20-25% of the value of equipment generated during its assembly at the construction site. For example, almost 3 times cheaper to bring the reactor from the factory at a nuclear power plant in assembled form, than to collect it by parts on the spot. In addition, many Modern technologies require factory assembly, when undesirable any subsequent mechanical intervention in the once assembled equipment. The use of large heavy equipment reduces the time of commissioning of facilities, reduce the size of construction sites, increases productivity, reduces cost and complexity of installation.

Water System
Nov 29, 2018 News
The cooling is caused by the spraying of water with a special fog nozzle under high pressure. The oxygen concentration in the air decreases and is replaced by the mist, because the saturation limit has been reached. In addition, the cooling time of the fumigation system inhibits the fire development. This caused less smoke, which can prove life-saving. Also the chronic staff shortages at the Fire Department shows how important this property is. In a fire, the resources be deployed urgently to delete.
The evacuation comes then often too short and also poses a potential risk for the safety of firefighters. Another advantage of a fine spray plant of the type of fog system is located in the lower water consumption. This reduces logistical problems and reduced the dimensions of the fire-fighting equipment. Example: If a sprinkler system is designed so that water needs this 33 liter per square meter, so consumed one, however, Water is only 0.24 Liter.Der reason for this same interpretation in the modified effect of firefighting and indirect delete the spatial effect. And results in the next advantage of this type of fire extinguishing systems.
The fog spreads out in all directions and unfolds its effect up to the smallest detail. A sprinkler system can spray only from top to bottom and reach therefore spatially limited and massive consumption of water used. This permits the use of more sensitive fire alarm systems (BMA), which much earlier to detect smoke and allow a limit, or putting out the fire at an early stage, because when sprinkler systems a massive use of water is given at an already advanced stage of the fire. Smouldering fires or light fires are still not recognized in these stages. This eliminates the still not sprinklers but being insensitive indoors this technique economic, because no high pressure pipe and high pressure pump must be installed. This means also less security and technology requirements. Sensitive buildings, fire a high risk for life, the environment and goods, the effort in relation to the target stands. The insurance companies, who can see an opportunity to reduce damage and reduce the risk premia, thereby increasingly recognise that.
