OK-DL-150 Single-Arm Drop Testing Machine

Overview

The OK-DL-150 Single-Arm Drop Testing Machine is an electromechanically actuated vertical impact tester engineered for standardized evaluation of packaging integrity under free-fall shock conditions. It operates on the principle of controlled gravitational acceleration, enabling repeatable simulation of real-world handling hazards—including corner, edge, and face drops—during logistics and distribution. Designed in accordance with the fundamental mechanics of inertial impact testing, the system delivers consistent kinetic energy transfer to test specimens by precisely regulating drop height and orientation. Its single-arm dual-column architecture provides unobstructed access for specimen loading and orientation adjustment, while integrated electro-hydraulic control ensures stable descent, controlled deceleration, and safe recovery cycles. The machine is calibrated and validated against internationally referenced mechanical shock test methodologies, serving as a core tool in packaging development, quality assurance, and regulatory conformance workflows.

Key Features

• Single-arm, dual-column structural design with open-front configuration for rapid specimen placement and multi-angle positioning (face, edge, corner)
• Motorized vertical lift and electrically triggered drop mechanism with programmable release timing
• Digital height display with rotary encoder-based position tracking—height accuracy maintained within ±2% or ±10 mm of setpoint
• Hydraulic damping system integrated into the base frame to absorb impact energy, minimizing structural resonance and extending service life
• Adjustable impact surface alignment; angular deviation between impact plane and base plate ≤5°, verified per GB/T 4857.5 metrological requirements
• Robust steel frame construction with reinforced base plate (170 × 120 × 15 cm) capable of withstanding repeated 100 kg impacts at heights up to 200 cm
• Compliant power interface: 220 V, 1-phase, 9 kW supply—includes overload protection, emergency stop circuitry, and interlocked safety guards

Sample Compatibility & Compliance

The OK-DL-150 accommodates full-size transport packages up to 80 × 80 × 100 cm, supporting both empty and fully loaded configurations per ISO 2248:1985 and GB/T 4857.5 test protocols. Its modular mounting interface allows secure fixation of irregularly shaped or oversized units using optional strap fixtures or custom cradles (available upon request). The system satisfies essential requirements for packaging performance verification under national and international standards, including GB/T 4857.1 (labeling conventions), GB/T 4857.2 (conditioning protocols), GB/T 4857.17 (test plan formulation), and GB/T 4857.18 (quantitative test parameter specification). While not inherently 21 CFR Part 11 compliant, audit-ready documentation—including calibration logs, maintenance records, and operator training summaries—can be generated to support GLP/GMP-aligned validation processes.

Software & Data Management

The OK-DL-150 operates via a dedicated industrial control panel with tactile push-button interface and real-time LED height readout. Though it does not feature embedded PC-based software or network connectivity, all operational parameters—including drop height, cycle count, and activation timestamp—are manually logged in accordance with internal QA procedures. Users may integrate external data acquisition systems (e.g., USB-connected accelerometers or high-speed cameras) to capture transient impact profiles. For enterprises requiring digital traceability, third-party SCADA or LIMS interfaces can be configured via RS-485 or analog I/O expansion modules (subject to engineering review). Calibration certificates and mechanical verification reports are supplied with each unit and updated annually per ISO/IEC 17025-recommended practice.

Applications

• Validation of corrugated box compression strength and seam integrity during vertical impact events
• Evaluation of cushioning material efficacy (e.g., foam, air pillows, molded pulp) under dynamic load conditions
• Verification of electronic enclosure robustness prior to global shipment (e.g., consumer electronics, medical devices)
• Development-stage testing of e-commerce packaging solutions subjected to last-mile delivery stresses
• Internal QA screening for automotive component shipping containers exposed to warehouse drop hazards
• Supporting ASTM D5276 (drop test for rigid shipping containers) correlation studies when used with supplementary instrumentation

FAQ

Does the OK-DL-150 support automated test sequencing or programmable drop patterns?

No—the unit performs single-drop operations with manual height setting and trigger initiation. Multi-cycle sequences require external timer integration or operator intervention.
Is the impact base plate replaceable or configurable for different surface hardnesses?

The standard base is a solid steel plate (HB 200–220); optional hardened steel or rubber-faced inserts can be supplied to simulate concrete, asphalt, or composite floor surfaces.
What maintenance intervals are recommended for hydraulic damping components?

Hydraulic oil inspection is advised every 500 operational hours; full fluid replacement and seal check every 2,000 hours or annually—whichever occurs first.
Can this machine be used for ISTA-certified test protocols?

Yes—when operated within defined height, mass, and orientation tolerances, the OK-DL-150 meets equipment criteria for ISTA 1A, 1B, and 2A procedures; formal ISTA certification requires lab-specific procedure validation.
Is technical documentation available in English with metric-only units?

Yes—user manuals, calibration certificates, and compliance summaries are provided in English with SI units exclusively; no imperial conversions are included.
