Underground Mining Equipment
Hydraulic Bolting Jumbo, HT92-D
The HT92-D hydraulic bolting jumbo is specifically designed for bolt support operations in narrow tunnels and confined underground environments, such as metal mines and other excavation sites. Its specialized feed system allows it to operate efficiently within spaces as tight as 2.4 m × 2.4 m.
Powered by an advanced electro-hydraulic rock drilling system with anti-jamming protection, the hydraulic bolting jumbo ensures high drilling speed and operational efficiency. With a compact and agile build, this bolting jumbo improves mobility and significantly enhances the underground working environment, boosting both safety and construction productivity.
Support your underground operations with a compact, intelligent solution that delivers precision, boosts safety, and keeps your projects running smoothly where space is limited.
