Proper Sling Use and Safety Guidelines

Marine Travelift boat hoist sling inspection and replacement guidelines are critical to the productivity of your machine and marina. By following the recommended inspection and maintenance procedures below, your marina will maximize its efficiency for the long haul and ensure that each pick is handled in the safest way possible.



Before the first haul out of the day is made, and before every use, a sling and rigging inspection must be followed. Slings and rigging must also be appropriately inspected before each lift is made during daily operations.

All new, altered, modified, or repaired slings and rigging hardware must be inspected by a qualified person to verify their compliance with the applicable provisions of ASME B30 standards and inspections before being placed into service. Written, detailed sling and rigging inspection records should be kept for all slings. These records show a description of the new sling and its condition on each subsequent inspection.

Periodic inspections of the slings and rigging hardware must be made and their frequency should be based on:

  • Frequency of use
  • Severity of service conditions
  • Experience gained on the service life of the similar gear used in similar applications.


Daily Scheduled Maintenance (Before Operation)

Inspect Synthetic Web Slings

Slings should be inspected by a qualified person before every use. While in use, the operator should make certain the slings are not damaged by:

Cutting – Straight line damage to one or more layers of the webbing yarns on the side of the cutting contact usually caused by edges of the loads or adjacent equipment.

Snagging – Pulls of the webbing surface yarns away from their fabricated surface usually caused by nails or hull protrusions.

Wear – Broken synthetic fibers at the contact surface or scratch marks on metal surfaces and can be on any part of the load bearing sling or rigging.

Pinching or Crushing – Material is unable to sit or lay in the position that it was fabricated or manufactured or to no longer maintain a dimension to which it was fabricated or manufactured.

Heat Damage – Caused by welding, burning or being pulled across a surface and evidenced by a charring and melted condition of the webbing.

Chemical Damage – Stains, brittleness or a melted appearance are visible.

Foreign Matter – A “gritty” feeling to the synthetic webbing and a “dust” appears when the webbing is vigorously shaken.

Knots – The sling webbing not lying flat or curving in the width of the webbing.

Ultraviolet Damage – Stiffness in the webbing formed by its “new” condition and lack of “slipperiness” to the touch.


Sling Removal Criteria

A sling must be discontinued if damage such as the following (but not limited to) is visible:

  • Any condition that causes the user or inspector to doubt the sling or rigging’s ability to be used safely.
  • Cracks, bends, distortions, pitting or significant abrasion in any metal fitting rigging component of the sling or
  • Missing or illegible sling identification
  • Acid or caustic burns in the sling
  • Melting or charring of any part of the sling
