ZDFJ76B/1
Low-roof Face Drilling Jumbo
ZDFJ76B/1 is a hydraulic face drilling jumbo intended for low-vein mining. Its low-profile carrier and aluminium feed support face drilling in restricted-height tunnels.

Built around your working task.
Review the model and technical reference together with your application requirements. Provide hole diameter, depth, orientation and the working profile. Identify the available power, water and access conditions for the proposed equipment.

Face drilling in restricted-height workings
ZDFJ76B/1 is a low-roof hydraulic face drilling jumbo described for low-vein mining. The source combines a low-profile carrier with an aluminium feed and parallel-holding boom. This is a distinct layout, not a reduced-height claim applied to every machine in the jumbo range.
The material gives a minimum tunnel-height reference of 1.3 m and a cross-section of up to 29 m². Those figures need to be read with the machine's actual working envelope. Send the tunnel profile and hole pattern so travel clearance and drilling reach can be reviewed separately.
Documented construction and equipment
The direct-control drilling system includes rotation-pressure-controlled feed for anti-jamming. The specification lists water-mist flushing with external water and air supply and a rock-drill lubrication kit; air-supply hole blowing and big-hole drilling kits are marked as options.
The feed specification includes a clamp-style hose arrangement, rubber-bushing centralizers and dowel spacer. Customized feed length, automatic rear-boom lubrication and boom suspension are listed as options.
A manual lubrication kit and hydraulic oil thermostat are listed; a rig-washing hose and reel and a hydraulic oil tank heater are optional.
Feed length and hole depth are different measurements
The documented feed length is 3600 mm, drill-rod length 2500 mm and hole depth 2300 mm. Each refers to a different part of the drilling arrangement. Do not use the full feed length as the achievable hole depth in a project specification.
Direct control and anti-jamming functions are described in the source, with a maximum feed-force reference of 15 kN. The exact drill configuration needs confirmation because the material contains inconsistent rock-drill references. This page therefore avoids a universal hole-diameter or impact-power claim.
Prepare the low-profile jumbo inquiry
Provide roof-height changes, route width, intersections and the places where the machine will set up. The reference length with feeds is 13450 mm and width is 2480 mm, so low height alone does not settle whether the carrier fits the route.
Specify the target hole depth and the available electricity and utilities. Ask for a current dimensional and coverage drawing, the offered drill and feed, and the equipment included. If height is not the main constraint, compare the ZDFJ76A1 single-boom arrangement on its own technical references.
Selection questions
What should I include in a product inquiry?
Provide hole diameter, depth, orientation and the working profile. Identify the available power, water and access conditions for the proposed equipment.
Which technical details need confirmation?
Confirm rock drill configuration, hole range and the complete machine envelope for the proposed tunnel. Conflicting rock drill values are omitted.
How do I request the selected configuration?
Send the model or series reference and your project requirements through the inquiry link. Include drawings or the existing equipment reference where available.
Can the machine drill a hole equal to the feed length?
Not on that basis alone. The source separately lists a 3600 mm feed, a 2500 mm rod and a 2300 mm hole depth. Use the confirmed drilling configuration and hole-depth specification.
