ZDFJ86A/2
Twin-boom Face Drilling Jumbo with Basket
ZDFJ86A/2 is a twin-boom hydraulic face drilling jumbo for medium-sized drifts and tunnels. The source specifies two ZDG550 rock drills, telescopic feeds, PLC control and an articulated four-wheel-drive carrier.

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.

Twin rock drills and telescopic feeds
ZDFJ86A/2 is a twin-boom face drilling jumbo whose source specifies two ZDG550 rock drills and telescopic feeds. The stated impact power is 24 kW per drill, with a 32–76 mm hole-diameter range. Keep the per-drill rating distinct from the machine's electrical supply requirements.
The boom arrangement includes parallel holding and a 1600 mm extension reference. Request a working-envelope drawing for your face pattern. The stated coverage of up to 112 m² does not establish that every tunnel shape of that area can be reached from one setup position.
Documented construction and equipment
The boom holds the feed parallel during positioning. The document describes a modular boom bracket with W/X console arrangements for width and height, and a telescopic feed with 1800 mm extension.
The water system includes a hydraulic booster pump with a stated minimum inlet pressure of 2 bar and flow and pressure guards. Hydraulic equipment includes two separate pump groups, an oil-temperature gauge and an oil-filter indicator.
The electrical table lists two 75 kW motors, 380–1000 V and 50–60 Hz, together with thermal overload protection, phase-sequence indication and leakage indication.
Plan for the machine and its working arrangement
The supplied reference lists 16300 mm length, 2960 mm width and 43000 kg weight. These dimensions make route geometry and setup space a specific part of the inquiry. Provide intersections, gradient transitions and the available working area together with the tunnel section.
A basket is shown in the source, but its rated load is not provided. If personnel access from the basket forms part of the project, request the exact basket specification and applicable documentation. Do not derive a load rating from the photograph or from another machine.
Electrical configuration and related equipment
The reference lists two 75 kW main motors and a 380–1000 V supply range. That range does not mean one unconfirmed machine can be connected to any site supply. Identify the available supply and request the offered electrical configuration, connections and required utilities.
The ZDG550 page gives a separate view of the documented rock drill. It is useful for a component inquiry, while the whole jumbo still needs a machine-specific configuration review. Some engine and axle references conflict in the source, and should be settled in the final quotation.
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 the exact boom, basket and feed configuration before ordering. Technical values apply to the documented configuration.
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.
Is the basket load rating available?
The supplied image shows a basket, but the reviewed source does not provide a rated load. Request the basket specification and relevant documentation for the offered machine before planning that task.
