UNIC URW-546 CDER

The UNIC URW-546 is a powerful and versatile mini spider crane, designed to deliver exceptional lifting performance in confined spaces and restricted-access environments. Offering an impressive maximum lifting capacity of 4 tonnes at a 2.5-metre radius, the URW-546 combines substantial lifting power with compact dimensions, making it an ideal solution for demanding industrial and construction applications.

With a maximum lifting height of 16 metres and a working radius of up to 15.52 metres, the URW-546 provides excellent reach and flexibility for a wide range of specialist lifting operations. Its six-section hydraulic telescopic boom and 360° continuous slewing capability allow for precise load positioning, even in areas where larger conventional cranes may struggle to operate.

Measuring just 1.4 metres wide, the UNIC URW-546 is particularly suitable for accessing restricted working areas, passing through industrial doorways and operating in locations where space is limited. Its adjustable outriggers provide flexibility when setting up on site, while optional variable footprint technology allows the crane to accommodate challenging working environments.

For enhanced operator control and safety, the URW-546 comes equipped with radio remote control, allowing the operator to maintain clear visibility of the load from a suitable, safe position. An integrated Safe Load Indicator (SLI), intelligent voice warning system, overwind alarm and overload protection features help support accurate and controlled lifting operations.

Powered by a low-emission Tier 4 diesel engine, the URW-546 also offers an optional mains electric power system, making suitably equipped models particularly effective for indoor applications and environments where exhaust emissions need to be minimised.

Additional options, including a fly jib and searcher hook, provide increased versatility for specialist lifting requirements, with maximum lifting heights of up to 18.46 metres depending on the configuration.

Ideally suited to machinery installation and removal, factory maintenance, steel erection, glazing installation, building restoration and restricted-access lifting, the UNIC URW-546 delivers a practical and reliable solution for challenging lifting projects.

Combining impressive lifting capabilities, compact dimensions and advanced safety technology, the URW-546 is an excellent choice for contractors requiring powerful and precise lifting performance in areas where access and working space are restricted.
