Zero-tail off-road compact crawler excavator PX-25U with 2550 mm digging depth for narrow sites, small-mine support and complex terrain.
The PX-25U is a zero-tail, off-road compact crawler excavator developed for contractors working in complex road conditions, tight urban spaces and small-mine support roles. Its zero-tail swing design lets the machine rotate within its own track footprint, eliminating the risk of striking obstacles in narrow work positions, while the rugged crawler chassis provides stable traction across irregular terrain. With a 2.5 t operating class, standard bucket configuration and a maximum digging depth of approximately 2550 mm, the PX-25U combines maneuverability with genuine digging capacity for demanding small-scale projects.
The zero-tail design is the defining feature of the PX-25U. The counterweight and upper structure stay within the track width during rotation, which allows the operator to dig, swing and dump alongside walls, equipment or other vehicles without constant repositioning. This characteristic is especially valuable on complex road surfaces and in narrow work positions where a conventional tail swing would create a safety hazard or slow down the work cycle.
Underneath, the machine is mounted on a heavy-duty crawler undercarriage powered by a Yanmar-compatible diesel drivetrain, giving it dependable traction on soft or uneven ground. The robust hydraulic circuit delivers precise control for a standard bucket and a wide selection of optional attachments. With a maximum digging depth of roughly 2550 mm, the PX-25U handles excavation, trenching and utility work while remaining easy to transport between sites.
