Instructions for the Safe Use of Ladder Jacks


WARNING: Failure to read and follow instructions on the use of ladder jacks could result in personal injury or death.


General Safety Instructions

  1. DANGER! Metal Conducts Electricity! Be careful! Do not let ladder jacks come in contact with live electrical wires.
  2. Use only 375 pound (Type IAA), 300 pound (Type IA) or 250 pound (Type I) duty-rated ladders with ladder jacks.
  3. Do not overload platform or ladders.
  4. Not recommended for use with wood runged ladders.
  5. Recommended for one man use. Not for use with more than 2 men spaced at least 8 feet apart. Only one man on a 250 pound rated platform.
  6. If platform is 10 ft. or more above the ground, use a body harness secured to a lanyard, fall prevention device and a lifeline secured to a solid structural member. Do not attach lifeline to the ladder, ladder jack, or platform.
  7. Set ladders on a firm, non-skid surface.
  8. The maximum length and width for a fabricated metal platform when used with ladder jacks is 32 feet long by 20 inches wide.
  9. Contact plank manufacturer for proper use of laminated wood planks.
  10. Use of natural wood planks is not recommended.

Proper Angle Set-Up

Set ladder at proper angle by placing your toes against the bottom of the ladder. Stand erect. Extend your arms straight out. When palms of your hands contact the top of the rung, which is about shoulder level, ladder is at approximately the proper angle (Check with other labels.) Use only at proper angle.

Inspection Before Each Use

  1. Inspect thoroughly for missing or damaged components, including fasteners. Never use damaged ladder jacks, ladder or planks. Never make repairs.
  2. Keep equipment clean of all foreign material (wet paint, mud, snow, grease, oil, etc.)
  3. Destroy equipment if damaged, excessively worn or exposed to fire or chemicals.

General Precautions Before Each Use

  1. Never leave a ladder set up and unattended. Special care should be taken to keep children away from all ladders.
  2. Always keep ladder and ladder jacks clean of all foreign materials. Destroy if exposed to excessive heat or any corrosive agent.
  3. You should never use a ladder if you are not in good physical condition.
  4. Windy conditions require extra caution.
  5. Stay focused on safety whenever you are on the ladder, and keep your body weight between the rails.
  6. Keep shoes clean.

Proper Set-Up and Use

  1. Use only 375 pound (Type IAA), 300 pound (Type IA) or 250 pound (Type I) duty-rated ladders with ladder jacks.
  2. Follow instructions provided with platforms and ladders.
  3. Use ladders only at proper angle.
  4. Secure top and bottom of ladder to prevent movement before attaching ladder jacks.
  5. Make sure every hook engages a rung when placing jacks on ladders.
  6. Adjust the brace until the platform surface is horizontal. Make sure the adjusting mechanism is fully engaged and locked.
  7. Minimum platform width required: Fabricated platform = 12". Wood platform = 18".
  8. Maximum platform height shall be 20 ft. above the ground.
  9. Platform must overhang support by at least 12 in. and no more than 18 in. Do not use this overhang. Securely fasten platform to jacks to prevent movement — this is especially critical when using guardrail systems.
  10. Use guardrails and toeboard whenever platform is 10 ft. or more above the ground.
  11. Set-up must comply with applicable ANSI, OSHA, state and local codes.
