HOW IS a Tower Crane

BUILT?

Jib

The longer arm that lifts the load

Trolley

Carries the load by extending and moving along the jib

Oper

Base

rator’s Cab

oom that the crane trolled from

crete slab orts the crane

Counter-Jib

Holds the motor and counterweight

Counterweight Large concrete slabs to balance the load

Tower

This Gives the tower crane it’s height

12 Delivery

12 trucks carry pieces of the tower crane to it’s destination where it will be built

TRUCKS

1

The frame

A steel frame is made to strengthen the concrete

2

Concrete

Concrete is then poured into the frame

3

Setting

Once the concrete sets, the supports are removed

4

Embedding

Large anchor bolts are embedded deep into the concrete

Mobile Crane

A different type of crane is needed for this part of the process. The mobile crane is hired to help in early stages of construction

Constructing

The mobile crane lifts the jib and the counter jib into place so that it can then go on to heighten itself

Piece by piece

Small parts of the tower are carried by the trolley towards the mast

Building itself

Once the bottom of the frame has been erected and both arms have been added to the crane, the crane is then able to build itself

Ascending

The crane lifts itself until there is an empty slot in the tower. The new piece is then slotted in and this repeats.

Height

This can continue until the crane reaches upto

265 ft
