XCMG XUB125 Rock Bolter

Overview

The XCMG XUB125 is a mining rock bolter for bolting work in metal mines (underground gold, iron and copper mines), non-metal mines (gypsum and phosphorite), hydropower projects, small tunnels, inclined shafts and culverts.

When installing 1.8 m anchor bolts it suits headings from 3 m × 3 m up to 6.5 m × 5.8 m. The machine uses a hydrostatic transmission for a compact, manoeuvrable layout, and can be split into several modules so it can be lowered into a mine through a cage. Resin and split-set wedge tube bolts can be installed fully mechanically, with an optional mesh-hanging gripper.

Key Features

• Precise positioning — a fully parallel-holding, telescopic boom locates quickly and accurately; the box-section structure is stiff and absorbs shock well.
• Stable drilling — the drilling system includes anti-jamming and idle-strike prevention to raise drilling efficiency and reduce tool wear.
• Compact design — a compact, manoeuvrable machine that works well in confined spaces, with hydrostatic transmission.
• Safety protection — the machine covers are fully enclosed for reliable operator protection.
• Bolting attachment — resin and split-set wedge tube bolts can be installed fully mechanically, with an optional mesh-hanging gripper.
• Mine access — the machine can be divided into modules for lowering through a cage.

Applications

Metal mines (underground gold, iron and copper), non-metal mines (gypsum and phosphorite), hydropower projects, small tunnels, inclined shafts and culverts.
