Two of our mini spider cranes teamed up for another electrifying performance recently.
The UNIC URW-706s were used to change isolator heads at a substation.
For the first job, one of the cranes was used to take the weight of the busbars, which conduct the electricity and are bolted to the top of the isolator heads. The second crane was then used to lift the old isolator heads off and replace them with new ones.
The second part of the job including replacing earth switches, which weighed up to 500kg each.
The UNIC 706 is one of the biggest mini cranes in the range, possessing 6 tonnes of lifting power, yet still compact enough for lifting in a confined space.
From power stations to marinas, shopping centres to roof top operations, it has the perfect combination of working flexibility and power. This mini-crane is capable of handling loads of 6 tonnes to a radius of 3 metres and a height of 7.2 metres. An optional searcher hook and a 3.1m long fly jib deliver a maximum hook height of 22.7m
