Lifting equipment has been in use for many years, and it is difficult to see how much of our construction, energy and transport industries could operate without it. The ability to lift and move heavy objects is absolutely vital for all these industries, and many others. Even theatres rely on lifting equipment to put stage sets and lighting in place. While it can be seen as something that goes with modern, high tech industry, lifting equipment’s history is actually much longer than that.
The first cranes are thought to have been developed by ancient Egyptian, Greek and Roman builders. All of these cultures developed strong skills in construction – as evidenced by the buildings they created that still exist today. These early cranes would have used animal or man power to lift weight. Larger cranes would have a human-powered treadmill.
Fast-forward to the Medieval era, and technology in lifting equipment had not progressed, although cranes, hoists and other equipment were in limited use in warehouses and mills. As the industrial revolution progressed, technology improved. Whereas equipment had always been made largely of wood, stronger materials such as steel began to be used. There was also a move away from human powered devices, to those which harnessed new-found technologies and fuels. Steam powered cranes for example, were introduced, especially for work on railways. Progress was slow though: cranes powered by treadmill and hand winches continued to be used throughout the nineteenth century and beyond.
Today, technology has developed to cover an … Read More . . .

The savings can be significant for a household that uses a lot of hot water and plans to stay in the same house for a length of time. On average, households change homes about every 5 years. If you are moving less than that, then installing instant hot water system may not save you much money. But that’s not the whole picture.
Saving money as the price of energy goes up is a concern for everyone. Greenhouse warming is here to stay and adjusting for not just today but the future is financially wise. The annual cost of operating a tank type water heater is on average about $500 for a household. By switching to an instant hot water heater using electricity will save about 40-45% or $200 to $$225 per year.
