When space is tight but lifting demands are high, the UNIC URW-506 mini spider crane is the machine many contractors reach for. Despite being compact enough to pass through a standard double doorway, it delivers serious lifting power, handling loads of up to 3 tonnes, or even 4 tonnes with a 5-fall hook. It’s a perfect example of strength and precision packed into a small footprint.


The URW-506 offers an impressive 16-metre maximum reach, giving operators the flexibility to take on a wide range of lifting tasks. Whether it’s glass installation, steelwork, or maintenance jobs in restricted spaces, the crane provides the reach and stability needed without the setup challenges of larger equipment.


Safety has also been built into every detail. A computer-controlled system with safe load indicators and warning lamps keeps operators in control, while the proportional radio remote makes it easy to position loads with accuracy. It’s reliable, responsive, and designed to take the stress out of complex lifts.


On many projects, the crane can be tracked straight through access points where traditional cranes would never fit, cutting down on setup time and opening up possibilities on sites where space is at a premium.
