Scaling Jumbo PX-XMPYT-88.3/220 | Underground

Product Overview

The PX-XMPYT-88.3/220 is a scaling jumbo built for underground roadway safety maintenance. It is engineered to remove loose rock and clean sidewalls after blasting, helping stabilize headings before the next production cycle. With a hammer head maximum height of approximately 6,500 mm and a horizontal reach of approximately 3,800 mm, the machine covers a practical working envelope for typical underground sections. Full hydraulic pilot control gives the operator precise, responsive positioning of the scaling head, while low-profile construction suits restricted underground spaces. Diesel or electric options are available by model, and final specifications are confirmed in the technical agreement and configuration sheet.

Product Description

The jumbo is built for the demanding rhythm of underground development. Its full hydraulic pilot control system allows smooth and precise movement of the scaling head, so loose rock can be scaled systematically across the roof and sidewalls. The hammer head reaches a maximum height of approximately 6,500 mm with a horizontal reach of approximately 3,800 mm, providing effective coverage in roadways while keeping the carrier inside the excavated profile.

Power is supplied by the YN 38 CAF 4 diesel engine, and the machine is designed for the low-profile, confined spaces typical of underground mines and tunnels. The primary working functions include loose-rock handling, scaling and sidewall cleaning, which together reduce rock-fall hazards and support safer travel through maintained roadways. The unit can be configured according to project requirements, with diesel or electric options available by model. Final specifications are defined in the technical agreement and configuration sheet.

Technical Specifications

Applications

The PX-XMPYT-88.3/220 is applied in underground mines and tunnels where loose-rock handling and roadway safety maintenance are required after blasting. Scaling and sidewall cleaning help keep headings stable and travel routes safe for personnel and equipment. The reach envelope and low-profile design let the jumbo work efficiently in typical underground sections, supporting cycle continuity in development operations. Diesel or electric options can be matched to ventilation and site power conditions, with final configurations confirmed in the technical agreement and configuration sheet.
