ZDFJ76A1
Single-boom Face Drilling Jumbo
ZDFJ76A1 is a single-boom electro-hydraulic jumbo for underground face drilling and tunnelling. Its parallel-holding boom and anti-jamming control support blast-hole and bolt-hole drilling.
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.

Single-boom drilling for the development face
ZDFJ76A1 is a single-boom electro-hydraulic face drilling jumbo. The source describes blast-hole and bolt-hole work, with a parallel-holding boom and anti-jamming control. Its 32–76 mm hole-diameter range and 3500 mm reference hole depth belong to this model's technical sheet.
A face-drilling inquiry should include the tunnel section and proposed hole pattern. That tells the reviewer where the feed must be positioned and how far the drill needs to reach. Overall cross-sectional area alone doesn't describe the corners, floor or sidewall positions within the pattern.
Documented construction and equipment
The hydraulic boom maintains the feed beam parallel during positioning. An optional telescopic feed can shorten the beam for roof and side-wall bolt-hole work where roadway space is limited.
Two extendable hydraulic jacks at the front and two at the rear support machine setup. The service-brake arrangement is described as two separate circuits.
The rock-drill table lists 50 L/min water consumption for the documented configuration.
Boom, feed and drilling controls
The source lists a 24 kW impact-power reference, rotation up to 300 rpm and maximum rotation torque of 980 Nm. These describe different drill functions. They should not be combined into a promised drilling speed without a review of rock conditions, drill steel and the proposed holes.
An optional telescopic feed is described for confined bolt-hole work. If that task matters to the project, include it explicitly in the requested configuration. Ask for the corresponding feed drawing and rod arrangement instead of assuming that an optional feed is included with the base machine.
Choosing between single-boom and twin-boom layouts
The ZDFJ76A2 page provides a twin-boom alternative. Compare the two using the same face profile, access route and drilling requirement. More booms alone do not establish an output increase; the working arrangement, available utilities and hole plan must also be considered.
For the ZDFJ76A1 quotation, request a coverage drawing, utility requirements and the exact feed configuration. Some height, engine and impact-frequency statements conflict in the supplied material, so these should be resolved on the final technical sheet rather than inferred from this overview.
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 impact frequency, engine configuration, roof height and drilling coverage. Conflicting values are not included in this reference table.
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 ZDFJ76A1 perform bolt-hole drilling?
The source describes bolt-hole work and an optional telescopic feed for confined locations. Specify the bolt-hole geometry and available space, then confirm the included feed and drilling configuration.
