Support and Service
A huge part of lift truck selection is to make sure that you maintain access to high levels of service and support. Each year, there seems to be a wider array of new players in the forklift industry. Even if they provide a nice price and a decent lift truck design, if they do not provide the regional or local service and support infrastructure, you must be ready for major stress when the lift truck goes down. Every lift truck model goes down eventually and service, parts and general questions must be addressed at some point.
You will normally want to have a nearby repair shop or dealer with a complete supply of the components you need for your particular unit. Be sure to visit the dealership or the repair shop and check their parts room in order to try to understand how many parts they stock. Make sure to ask that if they do not have the component you require, where will it come from? With a bit of luck, the answer would be from a regional or local distribution facility.
Furthermore, try to get some ideas as to how many of those specific units are presently being utilized in your area. This is really important for specialty trucks including turret trucks. If there are only a small amount of trucks being utilized in their service area that you must assume they might not be stocking many if any parts for them. Additionally, they could have very little overall experience in servicing that model as well.
Early Crane Evolution
More than 4000 years ago, early Egyptians created the first recorded version of a crane. The original device was referred to as a shaduf and was first utilized to transport water. The crane was made out of a pivoting long beam which balanced on a vertical support. On one end a heavy weight was attached and on the other end of the beam, a bucket was connected.
Cranes which were built during the first century were powered by animals or by humans that were moving on a wheel or a treadmill. The crane consisted of a long wooden beam that was called a boom. The boom was connected to a rotating base. The treadmill or the wheel was a power-driven operation that had a drum with a rope which wrapped around it. This rope additionally had a hook that lifted the weight and was connected to a pulley at the top of the boom.
Cranes were used extensively during the Middle Ages to build the enormous cathedrals in Europe. These devices were also designed to load and unload ships in key ports. Eventually, significant developments in crane design evolved. For example, a horizontal boom was added to and became known as the jib. This boom addition allowed cranes to have the ability to pivot, therefore greatly increasing the machine's range of motion. Following the 16th century, cranes had included two treadmills on each side of a rotating housing which held the boom.
Even until the mid-19th century, cranes continued to rely on animals and humans for power. Once steam engines were developed, this all rapidly changed. At the turn of the century, IC or internal combustion engines as well as electric motors emerged. Cranes also became designed out of cast iron and steel rather than wood. The new designs proved longer lasting and more efficient. They can obviously run longer too with their new power sources and hence finish bigger tasks in less time.
