MAU 1002 2W ALU SF WH
Twin-wire shock absorption test equipment, guided-drop mass and transmitted-force method (EN 397/812 /12492 or similar), load cell and headform support, base and electric plant included, 4m aluminium × 2 (80×80 mm) column frame, 2 impactors, protection cage, automatic doors.
System Overview
- Application: Twin-wire shock absorption test equipment utilizing the guided-drop mass and transmitted-force method.
- Compliance: Fully compliant with EN 397, EN 812, EN 12492, and similar standards.
- Configuration: 4.4-meter height version featuring a double column frame made of 120×80 mm aluminium profiles. Included in the standard configuration are the structural base, electrical system, load cell and headform support, 2 impactor masses, and a full safety cage equipped with automatic doors.
Technical Features:
- Chassis Frame: Heavy-duty construction from aluminium ITEM profiles (120×80 mm, 80×40 mm, and 40×40 mm).
- Sub-Base Plate: 30 mm thickness zinc-plated steel plate, secured to the main frame via high-tensile screws.
- Main Ballast Base: Steel enclosure filled with concrete; total ballast mass: 700 kg.
- Drop Parameters: Maximum vertical drop height up to 2.7 m, yielding an impact velocity of 7 m/s.
- Guidance System: Twin-wire system utilizing Ø 3 mm C70 high-tensile steel cables equipped with an integrated tensioning mechanism.
- Leveling System: Adjustable base equipped with 14 grub screws (Ø 16 mm) for precise vertical alignment.
- Frame Anchoring: Secured to the structural base via 8 bolts (Ø 16 mm thread).
- Enclosure Safety Door: Automated protective door driven by twin pneumatic cylinders. Features a transparent polycarbonate front viewing panel and 3 mm polycarbonate lateral shielding. Integrated safety interlock switch prevents drop execution when doors are open.
- Lift Carriage: Precision water-jet cut Ergal 75 (aluminium alloy) plates. Equipped with a pneumatic automatic release system, complete with dedicated solenoid valve, limit switches, and photoelectric sensors.
- Catch Mechanism: Automatic drop carriage latching/hooking system operational during descent phases.
- Drop Carriage: Precision assembly made from water-jet cut Ergal 75 plates featuring a central core body (total base mass: 2 kg), engineered to accept modular drop masses.
- Instrumentation Support: Three-part load cell support structure featuring an integrated cell preloading system.
- Headform Positioning: Headform holder specialized for EN 397 testing (headform sold separately), equipped with a dedicated clamping device.
- Impactor Masses: Two C40 steel impactor masses supplied standard: Flat (Ø 130 mm) and Hemispherical (R 50 mm).
- Hoist System: Electric motor assembly with pulley and encoder for precise positioning of carriages to preselected drop heights.
- Electrical Integration: Complete electrical distribution system fully concealed and routed inside the structural aluminium profiles.
- Pneumatics: Complete pneumatic control circuit equipped with an integrated analog pressure gauge.
- Velocity Measurement: High-frequency infrared photoelectric barrier device for precise speed monitoring.
- Calibration: MEP pad supplied for impact data verification, including a dedicated load cell adapter.
- Surface Treatment: Anodized and triple zinc-plated finishes for enhanced corrosion resistance.
Technical Data & Installation Requirements
- System Weight: 190 kg (net weight, excluding the 700 kg concrete ballast base).
- Overall Dimensions (L × W × H): 800 × 1690 × 4840 mm.
