Project Tower Crane

dijous, 19 de gener de 2012

L'alumnat de 2n d'ESO de Taller de Tecnologia ha començat un nou projecte "Tower Crane". Com sabeu, és un dels grups plurilingüe experimental i ací teniu la descripció del treball realitzat:

name of the project is Tower Crane.

How the product works and how it is used. A crane is a type of machine, generally equipped with a pulley system, wire ropes and elerctric motor, that can be used both to lift and lower materials and to move them horizontally.

Short description of the parts. All tower cranes consist of the same basic parts:

  • The base is bolted to a large concrete pad that supports the crane.

  • The base connects to the mast (or tower), which gives the tower crane its height.

  • Attached to the top of the mast is the slewing unit -- the gear and motor -- that allows the crane to rotate.

On top of the slewing unit there are three main parts which are: the long horizontal jib (working arm), shorter counter-jib, and the operators cabin.
