Whether it’s a container crane, mobile crane or tower crane, one of the most important elements to consider when using any crane is the rope. Here at Rope Services Direct we supply only the highest calibre, premium quality wire rope, ideal for use in a wide variety of applications. One of these is for use as tower crane rope, which we detail below.
Tower cranes are used for lifting heavy building materials such as concrete slabs, steel, a wide range of building materials and machinery (e.g. generators). Often rising several hundred feet into the air, they are usually a local landmark and are designed to reach any part of the building safely and with ease. They are particularly important in the construction of particularly tall buildings that are hard to reach with any other type of crane. There are many safety aspects to consider when using a tower crane , read up on tower crane safety and guides before use.
A tower crane is made up of the following parts:
The base of the tower crane is incredibly important as it supports the rest of the crane and forms an interface between the top of the building and the crane itself.
The mast or tower adds height to the crane and holds the elevator as well as the operator’s cab.
The slewing unit
The rotating element of the crane that allows the crane to turn almost 30 degrees.
Selecting the right tower crane rope for your application
There are several different types of rope necessary to support the function of a Tower crane. These include pendant rope, derricking rope (if height of lift is low and rotation not critical) trolley rope and hoisting rope. Each rope will have a different set of requirements and a different rope will be needed for each application. When thinking about the type of rope you need, you will need to look at the type of loads that need to be lifted, the height and distances you need to cover, the radius of the swing and the degree of mobility required.
Hoisting ropes operating at high speeds and requiring large hoisting heights need to meet specialist requirements. The resistance in multi-layer spooling is crucial for most hoisting ropes.
The trolley is the section of the crane responsible for ensuring heavy loads can be placed with the utmost precision. Trolley wires require a high bending strength and extremely high breaking forces.
The use of Pendant ropes is required to lift high tension fatigue loads. When selecting a suitable ire rope be aware that the higher the rope’s crushing resistance the lower the ropes fatigue resistance tends to be.
