2 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
2.1 tower crane
power-driven slewing jib type crane with the jib located at the top of a tower, which stays approximately vertical in the working position
Note I to entry: A tower crane is equipped with means for raising and lowering suspended loads and for the configuration of such loads by changing the load-lifting radius, travelling of the load, slewing or travelling of the complete appliance. Some tower cranes perform several, but not necessarily all of these movements.
2.1.1 tower crane erected from parts
tower crane (2.1) which is transported to site in parts and erected with use of a separate lifting appliance where the design of the crane allows the crane to remain in the erected position in out-of- service conditions and to be dismantled for transportation to another site
2.1.2 self-erecting tower crane
tower crane (2.1) which is transported to site and mostly erected without use of a separate lifting appliance, where the design of the crane allows the crane to remain in the erected position in out-of- service conditions and to be lowered for transportation to another site
2.1.3 mobile self-erecting tower crane
self-erecting tower crane (2J2) mounted on a self-propelled or trailer mounted chassis
3 Types of tower crane
The following four groups of characteristics describe tower cranes:
a) assembly:
— erected from parts;
— self-erecting (rapid erection without use of an auxiliary appliance);
b) slewing level:
— top slewing;
— bottom slewing;
c) type of jib (boom):
— horizontal jib (also hammerhead type);
— luffing jib (boom);
— articulated jib (also gooseneck jib);
— extending jib;
