COUNTERWEIGHT FORMULA

W = Counterweight

L = Load Capacity of Hoist

a = Arm Reach

b = Backspan Distance (Distance between the fulcrum point and the center of the counterweights)

4 = Safety Factor (4:1)

Note: Counterweights must be a non-flowable material, and they must be attached to the outrigger beam.  Always use taut tieback wire ropes capable of holding the full load.

W = (La) x 4  ∕  b

HI-LO Climbers L.L.C.  Safety Checklist

The Hi-Lo Swing Stage System is regulated by Federal Law under the Occupational Safety and Health Act by means of Safety Standards referred to in part 1910.28 (Safety Requirements for Scaffolding.) Section G - (Two-point suspension scaffolds – swinging scaffolds) from the booklet “Occupational Safety and Health Standards.”

It is the operator’s responsibility to thoroughly inspect the equipment before beginning operation.  Keep in mind that it is your safety that is at stake.  Do not assume someone else has done all the necessary inspection.  Check it yourself to be sure.  As the old saying goes:  “It’s better to be safe than sorry.”

1. Know, understand and follow all federal, state and local safety codes, ordinances and regulations pertaining to suspended powered scaffolding.
   
   
2. Make sure all persons who install, operate or use this equipment read and fully understand this manual and use this equipment in strict accordance with these instructions.
   
   
3. Unauthorized persons must not be allowed to operate or use this equipment.  When not in use remove motor, position stage beyond reach or use other means to prevent use by unauthorized persons.
   
   
4. Carefully check all equipment before using.  Never use equipment that appears damaged or defective.
   
   
5. All hooks, parapet clamps, outriggers and anchoring devices must be tied back at right angles to the face of the building and tightly secured to a structurally sound portion of the building and support four times the intended load.
   
   
6. Counterweights must be made of a non-flowable material (no liquid-filled containers or sand bags) and be securely attached to the rear of the outrigger.
   
   
7. Weight of men, materials, components and staging must not exceed maximum payload.
   
   
8. Inspect wire rope carefully before rigging.  DO NOT use undersize or oversize wire rope.  (See Section 6.0 in the Operators Manual)  Wire rope must be inspected each day to make sure it is in safe working condition.  Look for the following: Kinks • birdcaging • rust and other corrosive damage • excessive heat or fire damage • electrical damage.
   
   
9. Use only recommended wire rope clips, thimbles and other hardware.  Do not use “U” type wire rope clips.
   
   
10. Wire rope must be protected from sharp or abrasive edges of building protrusions or surfaces.
    
    
11. Check all clearances before moving platform up or down.
    
    
12. Check secure electric power cord to scaffolding with a cord restraint and assure all connections are properly grounded.
    
    
13. Make sure platform, toeboards, guardrails and midrails are properly secured to stirrup frame or stage.
    
    
14. Check your installation by raising the platform or cage a couple feet off the ground.  Raise and lower platform to check all safeties and to become familiar with equipment operation.
    
    
15. All tools and equipment must be secured and tied off to prevent them from falling and injuring persons on the ground.
    
    
16. Operate the platform in a level position.
    
    
17. Use fall-arrest equipment attached to independent safety lines with rope grabs and lanyards at all times when working above ground.  Use a lanyard and rope grabs as high on the life line as possible.
    
    
18. Life lines must be attached to structural member of the building.
    
    
19. DO NOT attempt to operate or otherwise use this equipment in icy conditions or other adverse weather.  Accumulated ice on any part of staging and/or this equipment may affect its performance and safety and result in potential danger to the user.
    
    
20. DO NOT alter, remove or substitute any parts of this equipment.
    
    
21. Never attempt maintenance or replacement of parts while the unit is suspended.
    
    
22. Maintenance on Hi-Lo units must be performed only by factory authorized service representative or other qualified mechanic.
