 Re: lowering BIG blocks.
The reason why if I were to use a crane on the job described I would use one of larger capacity (and more expensive) is the loss in lifting capacity at greater distances. A franna does have a radius of around 30m but at that distance can only lift around 300-400kg.
An 80T crane can lift around 3T at 24m....the 100/120T crane could take the whole stick in one at 35m.
