Underground Hydraulic Bolting Jumbo
CYTM41/2
A compact bolting jumbo for support work in narrow drifts and tunnels, with automatic drilling, bolting and bolt changing.
Overview
The CYTM41/2 is designed for bolting support in narrow drifts and tunnels in metal mines and other underground projects. Compact, rigid and maneuverable, it improves working conditions and construction efficiency at the face.
Its telescopic 6-bolt rack is adjustable for 1.5–2.0 m bolts and, with a dedicated feeder, delivers effective bolting in drifts of 2.2–3.5 m. Electrically controlled pilot hydraulic rock drilling with an anti-jam device enables fast drilling, while advanced position and angle sensors enable automatic drilling, bolting and automatic bolt changing with improved positioning accuracy.
