Safe Operation and Maintenance Guidelines for Shake Tables

QuakeLogic safety

Our shake tables are precision instruments designed for safe and reliable operation in research and educational settings. Adherence to the following guidelines ensures optimal performance, safety, and compliance with operational standards. Failure to follow these instructions may void the warranty and could result in personal injury, equipment damage, or legal liability.

Safe Operation Norms

1. Pre-Operational Safety Checks

  • Visual Inspection:
    • Inspect the table, actuator, and control systems for visible signs of wear, damage, or loose components.
    • Check electrical cables for proper insulation and secure connections.
    • Verify that the shake table is mounted on a stable, level, and vibration-free surface using recommended mounting brackets.
    • Ensure the payload weight does not exceed the table’s specified capacity.
  • Setup Validation:
    • Confirm the operating area is free of clutter, non-essential personnel, and hazards.
    • Ensure the power supply matches the table’s voltage and frequency requirements, and install surge protectors to safeguard the system.

2. Operational Safety Measures

  • Training Requirements:
    • Operators must complete training provided by QuakeLogic or an authorized representative.
    • Maintain a record of certified operators and update training annually or after significant personnel changes.
  • Personal Protective Equipment (PPE):
    • Operators and nearby personnel must wear PPE, including safety glasses, gloves, and steel-toed shoes, during operation.
  • Operational Environment:
    • Operate within specified environmental conditions: 0°C to 40°C temperature and up to 80% non-condensing humidity.
    • Maintain clear warning signage around the shake table to alert of active operations.
  • System Monitoring:
    • Monitor the system using the Shake Table Control Software to ensure real-time tracking of parameters such as displacement, velocity, and frequency.
    • Remain within specified limits to prevent damage or system failure:
      • Displacement: ±125 mm (or model-specific range).
      • Velocity: Up to 0.8 m/s (or as defined per model).
      • Frequency: Maximum 15 Hz (or as defined per model).
  • Emergency Protocols:
    • Test the emergency stop switch before each operation to ensure functionality.
    • Halt operations immediately and disconnect power if unusual noises, overheating, or irregular vibrations occur.
    • Document and report all anomalies to QuakeLogic’s support team for further guidance.

3. Payload Handling

  • Secure the payload using the supplied mounting brackets or approved alternatives.
  • Center the payload on the table to avoid uneven loading and minimize stress on the actuator.
  • Avoid sharp edges or projections on the payload that could damage the table surface.

4. Prohibited Actions

  • Do not operate the table without securing the payload.
  • Avoid modifying the equipment or using it outside its intended purpose (e.g., applying loads exceeding specified capacities).
  • Never disable safety features or operate the table without functioning limit sensors.

Maintenance System

1. Routine Maintenance

  • Daily:
    • Clean the table and remove debris from moving parts.
    • Inspect cables, brackets, and connectors for wear or looseness.
  • Weekly:
    • Verify system calibration using the control software.
    • Inspect safety features, including displacement limits and torque shutoffs.
  • Monthly:
    • Lubricate actuator components and inspect for leaks, wear, or misalignment.
    • Check the control box for overheating or unusual noise during operation.

2. Comprehensive Maintenance

  • Quarterly:
    • Conduct a full inspection of electrical, mechanical, and software components.
    • Recalibrate the system to ensure displacement and velocity accuracy.
  • Annually:
    • Replace worn parts such as seals, cables, or sensors.
    • Engage QuakeLogic-certified technicians for professional servicing and system validation.

3. Maintenance Documentation

  • Maintain a Maintenance Log that includes:
    • Dates and types of inspections or repairs performed.
    • Observations and corrective actions taken.
    • Technician signatures for compliance and audit purposes.

Liability and Safety Compliance

1 Authorized Use:
* QuakeLogic shake tables are designed for research and educational purposes only. Use outside these applications may void the warranty and absolve QuakeLogic of liability.
2 Safety Accountability:
* Operators are responsible for ensuring compliance with these safety guidelines and the user manual.
* Institutions must ensure the equipment is used under trained supervision at all times.
3 Incident Reporting:
* Any accidents or malfunctions must be reported to QuakeLogic and documented internally to comply with safety protocols and regulatory requirements.
4 Modifications and Unauthorized Repairs:
* Modifying the shake table or conducting repairs outside of QuakeLogic’s guidelines voids the warranty and transfers all liability to the user.

Enhancing Longevity

  • Store the shake table in a clean, dry location with a temperature range of 0°C to 40°C when not in use.
  • Cover the shake table to protect it from dust.
  • Ensure regular software updates to the Shake Table Control Software to access the latest features and maintain system integrity.
  • Use only QuakeLogic-approved parts and accessories for replacements and upgrades.


By strictly following these norms, operators can ensure safe operation, optimal performance, and legal compliance for all QuakeLogic shake tables.
