13 Luffing-jib tower cranes, such as those made by Potain, have helped solve a lot of inner city construction problems when it comes to constricted sites.
“Among some of the key reasons for using luffing jib cranes is that especially over the last 15 years, they have helped to solve a lot of inner city construction problems when it comes to the fight for precious space in and around a construction site�
advantages and disadvantages in different application fields, therefore we can plan a key role in determining which model should be selected. Luffing-jib cranes are especially demanded for tall buildings on congested sites. They have a very short counter-jib and a variable working radius, which permit high productivity in extremely narrow spaces. Among some of the key reasons for using luffing jib cranes is that especially over the last 15 years, they have helped to solve a lot of inner city construction problems when it comes to the fight for precious space in and around a construction site. The luffing crane has a special design and the jib has the capability of lifting while standing vertical in the air at a minimum of 5m radius from the mass section (Of course, this is used as an example, and depending on the type of crane, this could vary). It is the opposite to the flat top crane, which must be left parallel to the project and at a fixed radius of the jib already pre-determined. The luffing jib tower crane has solved many issues for projects where over-sailing rights are not possible or very difficult to achieve in cities around the world, like in the United Kingdom. These rights are not usually given when the loads being carried by the crane must be brought over the top of neighbouring buildings that are public, government or have a heavy population of the general public, such as public transport stations. The luffing crane allows the jib and the load to stay within the construction site boundaries at all times and ensure the safety of the general public. Advantages of using luffing jib tower cranes are: 1. Luffing cranes are usually the best solution when a number of cranes are working on the same construction site, to avoid any kind of crash with other cranes or the surrounding buildings. With their variable working radius, they don’t interfere in the working area of the other cranes on site and they can be parked with a very reduced radius. However, construction site managers should have prior experience in supervising several luffing cranes operating simultaneously.
