Scissor Lift Pre-Operation

ANSI A92.20 daily pre-op for scissor-type MEWPs (vertical lift). Covers chassis, deck, guardrails, controls, and platform safety.

Inspection Setup

• Equipment identification recorded
  Record the unit ID, make/model, and location.
• Inspection date and time recorded
  Document when the pre-operation inspection was completed.
• Operator/inspector authorized and trained
  Inspector confirms they are authorized to perform the pre-use check and operate the lift if needed.

Chassis and Base

• Chassis free of visible cracks, deformation, or missing hardware
• Wheels, tires, and casters in serviceable condition
  Check for cuts, flat spots, loose components, or abnormal wear.
• Hydraulic system free of visible leaks
  Inspect hoses, fittings, cylinders, and the base area for fluid leakage.
• Battery or power source secure and undamaged
  Verify battery compartment, cables, connectors, and charging components are secure and free of damage.

Platform, Deck, and Guardrails

• Platform deck clean, dry, and free of slip/trip hazards
  Check for debris, oil, tools, loose materials, or standing liquid on the deck.
• Guardrails, mid-rails, and toe boards intact and secure
  Verify all required platform edge protection is present, properly installed, and not damaged.
• Gate or access chain closes and latches properly
  Confirm the entry point secures fully and does not create an opening during use.
• Platform extension deck, if equipped, operates and locks correctly
  Inspect extension deck movement, locking mechanism, and condition.

Controls and Safety Devices

• Emergency stop functions at ground and platform controls
  Test both emergency stop devices for proper operation.
• All control switches, joysticks, and buttons operate smoothly
  Check for sticking, delayed response, or unintended movement.
• Up/down, drive, and steer functions respond correctly
  Verify the lift raises, lowers, drives, and steers as expected without abnormal noise or movement.
• Alarm, horn, and warning indicators function
  Confirm audible and visual warning devices operate properly.

Final Safety Check

• No unresolved deficiency or non-conformance identified
  If any item failed, the lift must be removed from service and tagged out until repaired and re-inspected.
• Inspection completed and signed
  Inspector signs to confirm the pre-operation inspection was completed.
