Zero-tail compact crawler excavator PX-12U with telescopic chassis (750–950 mm), Kubota power and 1870 mm digging depth for confined sites and renovation.
The PX-12U is a zero-tail compact crawler excavator in the PX series, engineered for work in confined spaces where conventional machines cannot operate safely. Its zero-tail swing design keeps the rear within the track footprint, while the telescopic chassis adjusts from approximately 750 to 950 mm to pass through narrow doorways and passageways. Powered by a Kubota D722 engine rated at 10.2 kW, it delivers reliable performance for light construction, indoor renovation, and landscaping projects that demand compact, maneuverable equipment.
The PX-12U was designed around one requirement: productivity where space is limited. The zero-tail structure allows the machine to swing and dig alongside walls, fences, and building facades without risk of counterweight impact, and the telescopic undercarriage lets operators narrow the track width on demand for doorways and pedestrian barriers. Combined with compact overall dimensions, the machine enters jobsites that larger excavators cannot reach, expanding the contractor's range of payable work.
Behind the compact envelope, the PX-12U carries a proven Kubota D722 diesel engine and a hydraulic system tuned for smooth, metered digging. The machine reaches approximately 1870 mm digging depth and 2150 mm dumping height, enough for foundation preparations, pipe runs, and landscaping beds, while the standard bucket capacity of approximately 0.02 m³ supports efficient light excavation cycles. Attachment interfaces and configuration options allow the unit to be tailored to project requirements and operator preferences.

The PX-12U excels on narrow roadways and urban sites, where its zero-tail swing and adjustable track width keep traffic and pedestrians safe while work continues. Typical duties include indoor renovation, foundation preparation, trenching in restricted yards, and landscaping jobs around existing structures, delivering machine performance in spaces normally reserved for manual labor.
