Chison Mobile Scissor Lift (Sorting/Aerial Work) Operation Guidelines

(Safe Operation · Standardized Use)

I. Pre-Operation Inspection

1. Equipment Inspection
   • Structural Check: Verify that scissor arms, hydraulic cylinders/screws are free from deformation, cracks, or oil leaks.
   • Moving Parts: Inspect wheels and brakes for smooth operation, ensuring stability when locked.
   • Safety Devices: Test emergency stop buttons, limit switches, and fall arrest locks (if equipped).
   • Power System:
     • Electric Models: Check battery level or power connection.
     • Hydraulic Models: Ensure sufficient hydraulic oil with no leaks.
2. Work Environment Inspection
   • Ground Requirements: Flat, solid surface (recommended: concrete), slope ≤3°, free of oil or obstacles.
   • Work Area: Confirm no overhead obstructions (e.g., pipes, cables) and no pedestrian traffic nearby.
   • Load Confirmation: Total weight ≤ rated capacity (refer to nameplate).
3. Personnel Preparation
   • Operators must wear helmets and anti-slip shoes; harnesses are required for heights ≥2m.
   • Prohibit operation by intoxicated, fatigued, or untrained personnel.

II. Operation Procedures

1. Moving & Positioning
   • Release brakes and push the lift to the work location.
   • Align the platform center with the work point, then lock wheel brakes.
   • Ensure platform levelness; adjust support legs if necessary.
2. Ascending Operation
   • Confirm no oversized items (height/width exceeding limits).
   • Press the “Up” button, slowly raise to ~20cm above ground.
   • Pause to check stability; proceed to target height if normal.
   • Engage mechanical safety locks (if equipped) at working height.
3. Aerial Work
   • Sorting/Handling:
     • Distribute loads evenly; stacking must not exceed guardrail height.
     • Secure tools with lanyards to prevent drops.
   • Maintenance/Installation:
     • Mandatory harness use, anchored to secure points.
     • Never lean beyond guardrails.
4. Descending Operation
   • Clear all items from the platform.
   • Disengage safety locks, hold “Down” button to lower slowly.
   • Only move the lift after full descent.

III. Safety Prohibitions

⚠ Never:

• Overload, unevenly load, or lift unstable items (e.g., loosely stacked boxes).
• Work at height without lock engagement.
• Climb, shake, or adjust items during movement.
• Move the lift before full descent.
• Tamper with or remove safety devices.

IV. Emergency Response

• Malfunction: Hit emergency stop; report to maintenance.
• Hydraulic Failure: Use manual release valve (professionals only).
• Injury: Stop work, activate emergency plan, call for help.

V. Maintenance

• Daily: Clean platform, check hydraulic oil and fasteners.
• Weekly: Lubricate scissor arm joints; test safety devices.
• Long Storage: Release hydraulic pressure; store in dry conditions.
