We have chosen the 2 Tonne Chain Block, because it is small lightweight and portable. We have chosen 2 tonne for the same reasons why we chose 3 tonne on the strap as its better to be on the safe side. The chain block also includes mechanical load breaks, hardened alloy steel chains.

We have decided to use the double thickness sling 3 tonne 4m, This was chosen this because the design specification said the crane should be able to lift 1 tonne but just to be in the safe side, it was decided that we would rather be over than under.
The sling also has reinforced Becket eyes at each end which will give greater strength where the pulley is attached.
