Inspections You Should Be Able to Do.
Shackles (Bow & Dee Tips)
A shackle has two main paths, the body and the pin. The body can have the anchor shape (bow) or a chain shape (D type). Each body shape can be used, depending on the specific application, with a screw pin or bolt-type pin.
- When selecting the right shackle, refer to manufacturers' tables for the safe working loads of the shackles. The rated capacity should be imprinted on the shackle and be visible.
- Shackles are sized according to the diameter of the bow section rather than the pin size. Never use a shackle if the distance between the eyes is greater than listed in the manufacturer's tables.
- Use a shackle when 2 or more ropes must be placed on a hook.
What to inspect
- Inspect shackles regularly.
- Inspect the shackle eye and pin holes for stretching (elongation) and wear. Elongation means the metal is being overloaded.
- Inspect the shackle body for bending. A bent shackle indicates excessive side-loading.
- Inspect all shackle pins for distortion, surface blemishes, wear and fractures.
- All pins must be straight and all screw pins must be completely seated.
- Replace shackles that are bent, show excessive wear by more than 10% of the original diameter, or have an elongated eye or shackle pin holes.
Used in a variety of applications and industries, overhead hoists are vital in manufacturing and warehousing facilities. Due to the constant lifting, lowering and moving of large, heavy materials, it is essential to perform regular hoist inspections for both safety reasons and to keep operations running smoothly. Waiting until it is too late could be detrimental to both your employee’s safety and to the hoist itself. Putting a hoist inspection procedure in place will save you time, money and keep your operations from coming to a screeching halt.
