 APPLICATIONS

​​

  • Scissor Lifts and Bucket Trucks

  • Military Applications

  • Aerial Lifts - Helicopters

  • Scaffolds - Window Washers

  • Bosun Seats

  • Tree Trimmers

  • Crane And Static Loads

  • Fire Ladder Trucks

  • Painters and Plasterers

Example 1:

A user is standing in a movable bucket and lifted by the boom to an elevated position next to a pole top. He is connected to the bucket using a Wishbone device releasable tether and is provided protection from falling out of the bucket. When the person is positioned next to a pole he would connect the second "D" ring non-releasable tether connector to an anchor (i.e. choker) on the pole, which is totally independent from the bucket. If the boom or bucket should fail or collapse while the user is positioned next to the pole, the Wishbone system would separate the user from the bucket as it fell away and the person would remain supported by the pole.

Example 2:

As in example one a user is standing on an aerial lift platform and raised by boom to an elevated position next to a structure. He is secured by a Wishbone releasable tether to the lift and when he is next to the structure he attaches the second "D" ring non-releasable tether connector to a structure anchor point, he can then un-connect the releasable tether from the lift and transfer to the structure while being fully tethered and supported. Should the lift platform fail or collapse or move before the user un-connects from the aerial lift the Wishbone system would separate from the aerial lift leaving the user supported by the structure.

Example 3:

User operating an aerial lift or bucket truck, attach releasable tether connection with short positioning lanyard to bucket or platform lift, connect non-releasable tether lanyard with shock arrester to Boom attach point. This connection helps to prevent flip outs and tip outs. In the event the bucket or lift fails the Wishbone will release the connection to the bucket or lift leaving the user secured to the boom attachment.

The Wishbone™ device intended use is the ability to secure personnel loads by connecting to two anchor points at the same time, one anchor point being a non-movable anchor point (Permanent Structure) (see definitions in sect.1.1.0.) and the other anchor point being a movable anchor point (aerial lift) (see definitions sect.1.0).  The primary purpose of this configuration is, if the movable anchor point fails or moves away while the worker is connected to both anchor points, the Wishbone™ will release the releasable leg while maintaining connection to the non-release leg supporting the personnel. 

SECTION 4.0 OSHA LETTERS OF INTERPRETATION

OSHA Letter of Interpretation concerning the use of Wishbone™ to belt off to an adjacent structure from an aerial lift that requires belting off to the aerial lift. The excerpt (text in italics with emphasis by ed.) reads as follows; however, limited situations may exist where an adjacent structure poses no reasonably foreseeable risk of  failure. For example, such an instance might arise where the adjacent structure is a completed building or a completed (i.e., fully bolted-up) skeletal steel structure. In those instances, OSHA would consider the violation of §1926.453(b)(2)(iii) to be de minimis² and no citation would be issued. To view the OSHA letter of interpretation in its entirety go to: http://www.osha.gov see interpretations dated 02/02/04. For additional information, see letters of interpretation dated 05/03/01 “Use of aerial lifts to transport workers to elevated workstations and the letter of interpretation dated 02/23/04. Permissibility of attaching welding leads to an occupied aerial lift bucket and using an external lifeline to anchor fall arrest equipment.”

De minimis²- under OSHA’s de minimis policy, de minimis violation is those, which have no direct or immediate relationship to safety or health. No citation is issued.
 

FEDERAL AVAIATION ADMINISTRATION

FAA Part 133  EXTERNAL LOAD
HELICOPTER OPERATIONS

Under FAA Part 133 regulations, particularly concerning Helicopter External Load Operations, there are specific guidelines regarding safety and the use of personnel in these operations.

 

Tying a human to a permanent structure while attaching them to a helicopter is a complex safety issue. Here are some key considerations:

 

1. Safety Regulations: The FAA regulations emphasize the importance of safety during external load operations. Personnel must be secured properly, and their safety must *not be compromised.

 

2. Personal Safety Equipment: If personnel are to be involved in operations while connected to a helicopter, they must use appropriate safety harnesses and other personal protective equipment (PPE).

 

3. Operational Procedures: Any operation involving a human tied to a structure and connected to a helicopter should be thoroughly planned and reviewed for safety. This includes ensuring that there are procedures in place for quick release in case of an emergency.

 

4. Training: Personnel must be adequately trained in safety protocols associated with helicopter operations. 

 

5. Duration and Risk: Even if the connection is for a very short duration (like 10 seconds), the risks involved must be evaluated, and safety measures must be implemented to protect the individual.

 

Given these considerations, it would be essential to consult with safety professionals and possibly the FAA or relevant aviation authorities to ensure compliance with all regulations and to assess the risks associated with such an operation before proceeding.

INSPECTIONS: 

A safety representative for the Company (user) to determine usability shall inspect the Wishbone units at least once a year (annual). A record by unit serial number of such inspections shall be maintained by the Company for each unit inspected to include time in service and any items noted, condition of unit and if removed from service the reason for removal. The user shall make a daily inspection each day before use and any time during the day thereafter it is prudent to do so.

DAILY INSPECTION: 

  • Check general condition and security of webbing and attachments

  • Check that stainless slide pin is engaged through the nylon loop and into the aluminum tube retainer.

  • Check webbing for distortions, heating, burns, discoloration, fraying, staining, fading, wear, frayed or broken stitches.

  • Check hardware for wear, cracks, separation, looseness, and proper function of double locking snap hooks.

  • Check that three interlocking rings are properly connected and that the slide pin is engaged through the nylon loop and the retaining tube. (see Fig. "1").

  • Check the torque stripe on the hinge for cracking. If the torque stripe is cracked indicating separation of the hinge this means that the hinge will release at a value of less than 200lbs. (+-5%) (see Fig. "2") (this is not a serious condition indicating only that the hinge may release with less than 200lbs. force applied between connections "B" and "C" see Fig."3".

Upon conducting this daily inspection any questions or uncertainty regarding the condition of the unit or items found on this inspection or issues regarding suitability for use, should be directed to your supervisor and/or Company safety officer. The unit may be returned to the manufacturer for inspections at a nominal charge, when in doubt.

USES AND LIMITATIONS: 

  • Wishbone™  PERTS shall not be used to lift/suspend personnel or loads.

  • Wishbone™  is limited to a maximum load of 325lbs.

  • ​Wishbone™  has a suggested service life of 5 years from date of manufacture or on condition by inspection.

  • Wishbone™  lanyard and all of its components must be removed from service upon activation of the release hinge.

  • Remove Wishbone™  from service on condition when there is evidence of discoloration, fading, staining, or lack of suppleness of the webbing, elongation of rivet holes, fraying of webbing or stitching.

  • Remove Wishbone™ from service if subjected to or evidence of heating, melting, or singing of the webbing.

  • Remove Wishbone™  from service on condition, any of the hardware or material is excessively worn or has excessive play to include nylon line loop that is pinned through the rings.
