So you want to know the cost of a tower crane, thats a good starting question but its a bit like asking someone 'so how much does a house cost'
The answer to both questions is...
'well that depends'
First you have to decide what type of crane you want, secondly how long does it have to last and thirdly what is your budget, unless you are loaded like ol mate pictured above.
The gold standard in tower cranes is the Favco, there are some currently operating in Sydney that are in excess of 40 years old and provided they are maintained they will keep going. They have fewer break downs and are good lifters. An entry level Favco such as the M220DX pictured below will cost around $1.5 million including tower sections. They are available in diesel or electric with a max lifting capacity of 22 tonnes.
A Comadil CTT 361-20 is a good size crane able to do concrete panels, max jib length is 75 meters and they have a max lift capacity of 20 tonnes. These cranes can go up pretty high without needing to be tied into the building. This crane will cost around $1 million
For smaller sites a good option is a self erecting crane. They do not get anchored into a base like a normal tower crane but sit on outriggers just like a mobile crane. A 4 tonne self erecting tower crane will cost around $100K. They are much cheaper to set up and dismantle than a normal tower crane as they fold out and partially set and dismantle themselves. Mobile crane is only required to lift the crane into place before it is assembled and to move the counterweights which sit at the base of the crane. To rent one of these cranes would cost around $1,500 per week.
A 5 tonne tower crane is ok on smaller sites but may struggle with some things, at times a mobile crane may have to be bought in to move things such as heavy silt tanks, building sheds, containers. Forget about building with concrete pannels if you intend to use this crane. Pictured below is the Potain MC88, they cost $330K and for an extra $40K you can get a cabin. Forget about the cabin, these small cranes deflect quite a lot it would be no fun to operate this in the cab. Terex 5 tonne tower cranes are also becomming very popular in Sydney with Active Cranes importing and leasing quite a lot of these. To rent one of these cranes would cost around $2K per week.
All cranes drive differently and have their pros and cons. Maintaince and basic house keeping of the crane such as freeslewing daily play a part in ensuring the crane has fewer breakdowns and drives well. The prices given may vary depending on tower height and jib length. A cheaper option is to buy second from Construction Sales, just be wary when buying a second hand crane. The owner is usually selling for a reason, breakdowns will cost you as well as replacing motors, bearing and broken gears. Also cranes require a 10 year check that is quite expensive.
