Operation Considerations and Procedures for Scissor Lift Tables

I. Pre-Operation Preparations

1. Safety Inspections

• Visual Checks:

• Ensure the platform surface is free of debris, guardrails are intact, scissor arms show no deformation or cracks, and hydraulic pipes are free of leaks (for hydraulic models) or wires are undamaged (for electric models).

• Check that tires/legs (for mobile models) are stable and the ground is level (slope ≤3°) to avoid tilting during operation.

• Functional Tests:

• After powering on, test the emergency stop button, up/down buttons for responsiveness, and ensure limit switches work effectively (the platform should stop automatically at maximum height).

• Run an empty test 1-2 times to observe smooth lifting/lowering without unusual noises or jams.

  
  

2. Environment Confirmation

• Clear obstacles (e.g., wires, tools) from the work area and ensure no personnel are lingering around, especially noting that no one should stand below during high-altitude operations.

• For outdoor operations, cease use and secure the equipment in harsh weather (e.g., wind ≥ Beaufort scale 6, rain/snow).

3. Load Preparation

Strictly adhere to the platform’s rated load capacity (marked on the nameplate) and never overload. Place goods evenly at the center of the platform to avoid uneven loading and tilting.

When carrying personnel, ensure seat belts are worn and fastened to guardrail anchor points, with no more than the maximum allowed number of people (usually ≤2).

II. Standard Operation Procedures

1. Startup and Lifting/Lowering Operations

• Fixed/Mobile Platforms:

1. Insert the key or power on, and activate the operation panel (some devices require releasing the emergency stop button first).

2. Press the up button for slow ascent; release the button near the target height and fine-tune to the precise position.

3. For lowering, confirm safety around the platform first, then press the down button for steady descent; release the button to stop midway if needed.

• Differences Between Electric/Hydraulic Models:

• Electric models: Gentle operation, suitable for precise positioning (e.g., laboratory equipment lifting).

• Hydraulic models: Faster lifting/lowering, requiring slow operation under heavy loads to prevent shocks.

2. During Operation

• Prohibited Actions:

• Never adjust goods or personnel positions while the platform is moving to avoid center-of-gravity shifts.

• Do not dismantle guardrails, modify control circuits, or exceed height limits.

• Dynamic Monitoring:

• Monitor the pressure gauge (hydraulic models) or battery indicator (electric models). If pressure is abnormal or battery level drops below 20%, stop operations immediately and power off for inspection.

• If unusual noises occur (e.g., hydraulic pump Abnormal Noise，motor overload sounds), press the emergency stop button and resume only after troubleshooting.

3. Post-Operation Shutdown

1. Lower the platform to its minimum height, turn off the power switch, and remove the key (lock wheels/legs for mobile platforms).

2. Clean the platform surface, check for wear or abnormalities, and record usage in the Equipment Operation Log.

3. For long-term storage, lower the platform fully, disconnect power, and cover with a dustproof cover (protect from rain outdoors).

III. Emergency Handling

1. Power Outage or Malfunction:

• If the platform stops at height, do not climb down forcibly. Contact maintenance via intercom/alarm and use the manual lowering valve (hydraulic models) for slow descent.

2. Sudden Tilting:

• Press the emergency stop button immediately, have personnel remain still, and evacuate only after professionals assess stability.

3. Oil Leaks/Electrical Faults:

• For hydraulic models with leaking pipes, stop use immediately and keep open flame away; for electric models with leaks, cut off the main power and contact an electrician.

IV. Safety Standards and Certifications

• Operator Requirements: Personnel must receive pre-job training, be familiar with equipment performance, and never operate without certification.

• Compliance: Ensure equipment meets CE certification or local safety standards (e.g., China’s GB 25854). Conduct regular load tests (at least annually) and maintenance (quarterly).

V. Key Operation Points for Different Scenarios

By following these procedures and safety guidelines, you can maximize the efficiency of scissor lift platforms while ensuring personnel and equipment safety. For special models or customized functions, always refer to the equipment manual.
