Searcher hooks and fly jib boom attachments for our UNIC mini spider cranes are able to increase the lifting height and working radius of our cranes for taking on challenging jobs in restricted access areas.

These lifting accessories have often proven to be just the thing for taking on awkward lifting jobs. A searcher hook can help with tricky installation work around overhangs and soffits, whilst a fly jib extension gives a spider crane that extra reach to access difficult areas on site.

A searcher hook can be used to lift in areas where there is low headroom or if when a load needs to be installed close to a ceiling or overhead obstacle such as a soffit or balcony.

This attachment has a hook end fixed onto a crane’s boom which is ideal for suspending a vacuum lifter or other below-the-hook equipment.

Fly Jibs

east-claydonBy adding a fly jib extension onto the main boom of a UNIC mini crane, loads can be easily lifted to a greater working radius and moved over rooftops and high balustrades.

For example, this 1000kg fly jib was used with a UNIC URW-1006 crane to lift and lower circuit breaker silencers up and over 16 metre height overhead power lines at East Claydon National Grid substation. This fly jib increases the lifting height of the URW-1006 model to a massive 30.7 metres.

Our friendly team of experts can advise you which attachments can be used with each UNIC crane model, if you are not sure.

The capacity of a searcher hook is affected by the crane’s working radius and outrigger position, whilst the crane’s boom angle and the tilt angle of the load alters the capacity of fly jibs. Click on each of the links above to find the rated load charts for these attachments with different UNIC crane models.
