Unic URW-506 mini crane

Combine working flexibility and heavy lifting power

The URW-506 offers an optimal combination of working flexibility and heavy lifting power. This crane is capable of lifting 3 tonnes at 3.4m or up to 4 tonnes with an optional 5 fall hook block.

As with all the UNIC spider crane models carrying a safe load indicator, the URW-506’s working area limitation device allows the operator to pre-define the working area giving greater control and safety in sensitive areas. On approaching these limits, function speeds are reduced and an audible alarm is given before operation stops.
