Robot Arm Shotcrete Machine

 

The Saner SRSP35E/A9 Robot Arm Shotcrete Machine is a heavy-duty, state-of-the-art concrete spraying solution engineered specifically for underground mining, tunnel construction, hydropower engineering, and large-scale infrastructure stabilization.

 

 

Superior Mobility & 4-Wheel Steering
Equipped with a full-time 4WD system and dual-direction steering technology, enabling a 25° climbing capability and a tight 10 m minimum turning radius for agile navigation in narrow underground tunnels.

 

FOPS-Certified Protective Cabin
Features a hydraulic lifting cabin constructed with heavy-duty steel to international falling-object protection system (FOPS) requirements, safeguarding operators from overhead hazards while providing optimized visibility.

 

High-Efficiency Robotic Spraying
Utilizes a dual-fluid atomizing nozzle system that instantly integrates accelerating agents with concrete, reducing material rebound rates and optimizing structural integrity.

Mobility & Positioning: The machine travels to the designated underground sector using its 4WD diesel engine and positions itself accurately via 4-wheel steering inside narrow pathways.

Power Switching: The system connects to the local underground electrical grid, transitioning power input to the electric motor for pumping operations.

Material Feeding & Pumping: Ready-mixed concrete is loaded into the 650 L hopper, where the S-pipe valve and piston cylinders push the material continuously through delivery lines.

Spraying & Dosing: As concrete reaches the nozzle, the accelerator pump introduces precise doses of chemical admixture, ensuring rapid setting against walls or overhead arches.

 

 

ISO9001 Quality Management System: End-to-end monitoring covering raw material verification, precision machining, hydraulic circuit testing, and full-load functional checks.

CE Machinery Directive 2006/42/EC Compliance: Full adherence to European safety and health benchmarks for international market access.

FOPS Structural Certification: Protective cabin engineering designed to withstand heavy impact from falling rocks and debris.

 

 

Q1: What is the typical delivery lead time for an international order?

A: Standard machine production takes between 30 to 45 days, depending on custom configuration requirements and factory scheduling.

 

Q2: Does the equipment come with a manufacturer warranty?

A: Yes, Saner provides a standard 12-month or 2,000-operating-hour warranty covering core structural elements and main hydraulic components.

 

Q3: Are local operators required to have specialized certification to run the robotic arm?

A: Basic crane or heavy machinery operation experience is sufficient, and comprehensive remote/on-site training is included to ensure safe proficiency.

 

Q4: What type of routine maintenance is required for the concrete piston cylinders?

A: Regular lubrication of seals, daily cleaning of the 650 L hopper, and periodic clearance inspection of the chrome-plated cylinder bores are necessary.

 

Q5: Can the machine operate continuously in high-temperature underground mines?

A: Yes, the integrated heavy-duty air cooling system is engineered to maintain stable hydraulic fluid temperatures in hot subterranean environments.

 

Q6: What is the minimum tunnel cross-section required for the SRSP35E/A9 to maneuver safely?

A: The chassis is optimized for tunnels with a minimum width and height profile starting around 3.5 m × 3.5 m thanks to its 10 m turning radius.

 

Q7: How are replacement wear parts shipped during emergency project delays?

A: Critical wearing parts like nozzles and wear plates are stocked internationally and shipped via express air freight to minimize downtime.

 

Q8: Does Saner assist with local customs clearance documentation?

A: Yes, our export logistics team provides full documentation packages including Certificates of Origin, commercial invoices, packing lists, and CE compliance certificates.

 

Q9: Can the diesel engine be upgraded or modified for strict underground emission zones?

A: The machine comes standard with a clean National IV turbocharged diesel engine, and electric-only towing modes can be utilized in zero-emission zones.

 

Q10: What payment methods and commercial terms does Saner accept for global buyers?

A: We support flexible international trade terms including FOB, CIF, DDP alongside secure payment methods like irrevocable Letters of Credit (L/C) and wire transfers.
