A crawler mobile jaw crusher is intended for hard-rock quarries, primary crushing in mining operations, construction aggregate production and large-scale demolition sites. Track mobility allows autonomous movement inside the quarry, following the excavation front, without the need for a trailer or a fixed plant to which raw rock must be transported.
Crushing equipment is regulated in Europe with respect to safety and CE marking; a crawler mobile jaw crusher delivered in Europe is designed in line with the requirements of the Machinery Directive 2006/42/EC. For integration into a complete aggregate processing flow, see also the complete industry solutions.
Track mobility is the defining advantage of a crawler mobile jaw crusher: the hydraulic drive of the tracks, controlled remotely, allows autonomous movement over rough terrain and climbing gradients of up to 20°. Unlike wheeled plants, which require a trailer for transport, the tracked version repositions itself within the quarry, following the excavation front and minimizing material handling.
The European-version C series jaw crusher makes a crawler mobile jaw crusher a robust primary crushing machine: the large feed opening accepts particles of up to 720 mm, and the powerful jaw action reduces large blocks from a wide range of rocks. The adjustable closed-side setting (CSS) allows a broad range of output sizes, matching the product to the requirements of the next processing stage.
The pre-screening system of a crawler mobile jaw crusher increases efficiency and protects the crusher: the grate screen in the feeding zone separates the fine fraction already at size before it enters the crusher. This reduces unnecessary wear, increases the effective crushing capacity for material that actually needs reduction, and allows separate recovery of the fine fraction.
The magnetic iron separator and the dust suppression spray system complete a crawler mobile jaw crusher for clean, safe operation: the suspended magnetic separator removes iron pieces from the material, protecting the crusher from damage and producing a clean aggregate, while the spray system reduces the dust generated during crushing, for compliance with environmental requirements.

| Control | PLC with LCD display, IoT control, remote control |
| Start-up | Frequency-conversion start (host), variable-frequency feeding |
| Electrical cabinet | Double-layer, with overvoltage protection, dust-proof, lockable |

1. Raw rock is loaded into the large folding hopper.
2. The vibrating feeder, with frequency conversion, doses the material evenly.
3. The grate screen pre-screens the material, separating the fine fraction before crushing.
4. The C series jaw crusher reduces large blocks to the desired size.
5. The magnetic separator removes iron pieces from the crushed product.
6. The main belt conveyor discharges the product; the optional side belt separates the fine fraction.
The entire process is coordinated by the PLC system with IoT control and remote control. A crawler mobile jaw crusher produces high-capacity crushed aggregates directly in the quarry, repositioning itself autonomously on its tracks as the excavation front advances, with high efficiency and minimal material handling.
Which crawler mobile jaw crusher model should I choose?
The choice depends on the desired capacity and material size. The UCJ configurations cover from 80 to 415 t/h: UCJ-96 for medium production, and UCJ-116 and UCJ-120 for intensive production, with a larger feed opening. All use a European C series jaw crusher, suitable for a wide range of rocks.
How does track movement work?
The tracks of a crawler mobile jaw crusher are hydraulically driven and remotely controlled, with a speed of 0.6-1 km/h and a track width of 500 mm. The machine moves autonomously over rough terrain and climbs gradients of up to 20°, repositioning itself within the quarry, without a trailer.
What is the pre-screening system for?
The pre-screening system (grate screen) of a crawler mobile jaw crusher separates the fine fraction, already at size, before it enters the crusher. This increases the effective crushing capacity, reduces unnecessary jaw wear and allows separate recovery of the fine fraction, improving overall efficiency.
Is the delivered equipment new?
Yes. We deliver new, unused equipment, manufactured to order according to the chosen configuration. Construction uses components from established suppliers, with CE marking where applicable, and every plant undergoes a full inspection before shipment. You receive the technical documentation and operating manuals in your language.
How easy is it to transfer between sites?
Within the quarry, a crawler mobile jaw crusher moves autonomously on its tracks. For transfer between distant sites, the machine is transported on a trailer at the indicated transport dimensions. Track mobility eliminates the need for repositioning with auxiliary equipment on site and allows the excavation front to be followed.
What does the magnetic iron separator do?
The suspended magnetic separator of a crawler mobile jaw crusher removes iron pieces from the crushed material, with a magnetic field intensity of 70 MT. This protects the crusher and belts from damage caused by metals and produces a clean aggregate, free of ferrous contamination, essential for downstream uses.
Does it work in extreme cold or with special configurations?
For extremely cold working conditions, additional pre-screening, return screening and other special requirements, the configuration of a crawler mobile jaw crusher is adapted accordingly. A diesel "-E" variant with a 200-350 kW generator is also available, for energy autonomy on sites without grid access.
• Track mobility, hydraulic drive and remote control, autonomous movement over rough terrain, climbing up to 20°.
• European C series jaw crusher, robust primary crushing, for large particles and a wide range of rocks.
• Integrated pre-screening, removes the fine fraction before crushing, increasing efficiency and protecting the crusher.
• Intelligent feeding, vibrating feeder with frequency conversion and remote control.
• Magnetic separator and dust suppression, iron removal and dust reduction for a clean product and environmental compliance.
• PLC + IoT control, intelligent automation, remote monitoring and frequency-conversion start.
High crushing efficiency and convenient transfer are the direct result of track integration: autonomous movement eliminates the downtime of repositioning with auxiliary equipment, and crushing directly at the excavation front shortens the material handling cycle. For operations with advancing fronts, or for contractors working successively across several quarries, this combination of mobility and high capacity delivers superior practical productivity.
With a URSTAG crawler mobile jaw crusher, with hydraulic drive and remote control, a European C series jaw crusher, integrated pre-screening and a magnetic iron separator, you obtain a high-capacity primary crushing plant, able to move autonomously within the quarry, with high efficiency, intelligent PLC + IoT control and environmental compliance through the dust suppression spray system.
