Descriptions of the Fork Tine

Parts




Illustration 1g01598401

Typical Example

(1) Blade - The horizontal part of the fork tine that supports the load

(2) Heel - The radius on the fork tine that connects the blade to the shank

(3) Shank - The vertical part of the fork tine that has the hooks that support the fork tines attached.

(4) Hook or Hanger - Carriers that mount the fork tines to the carriage

(5) Tip - The free end of the blade

Surfaces




Illustration 2g01598403

Typical Example

(6) Upper Face of the Blade - The upper surface of the blade that carries the load

(7) Bottom of Heel - The lower surface of the blade that includes the tapers

(8) Front Face of Shank - The distance for the load center is measured from the front face of the shank and the face of the shank contacts the load.

(9) Flanks - The side faces of the blade and the shank.

(10) Blade Bevel - The upper and lower surfaces of the tip on the blade that are tapered for easy insertion of the fork tines

(11) Tip Flanks - The side surfaces of the tip on the blade that are tapered for easy insertion of the fork tines

(12) Top of Shank - The upper surface on the shank

(13) Shaft - The tubes that are mounted on the fork tines for mounting the fork tines to the carriage

Dimensions




Illustration 3g01598405

Typical Example

(T) Thickness - The thickness of the blade at the closest point to the heel

(W) Width - The width of the blade at the closest point to the heel

(BH) Back Height - The distance from the bottom of the blade to the top of the shank

(BL) Length - The length of the blade is measured from the front face on the shank to the tip on the blade.

(A) Angle - The angle from the upper surface of the blade to the front face of the shank.

Inspection of the Fork Tines

Check the fork tines daily for any twisting or bending of the fork tines. If any twisting or bending is observed, the fork tines should be changed prior to any lifting operation. If the fork tines are damaged, consult your AVSpare dealer.

Check the fork tines for wear or for damage. Inspect the welds, the locks, the shafts, and the fork tines for damage. If the components are damaged, consult your AVSpare dealer. Refer to, "Daily Inspection" for additional information.

Blade Thickness




    Illustration 4g01600073

    Typical Example

  1. Measure the thickness of the shank. Ensure that the measuring device is held square across the shank in order to acquire an accurate measurement.



    Illustration 5g01600074

    Typical Example

  1. Measure the blade of the fork tine near the heel. Ensure that the measuring device is held square across the blade in order to acquire an accurate measurement.

  1. Compare the measurement of the blade and the measurement of the shank.

  1. If the difference in measurements is less than 10%, the fork tine can remain in service.

  1. If the difference in measurements is greater than 10%, the fork tine must be taken out of service. Fork tine wear that is greater than 10%, represents a 20% reduction in the capacity of the fork tine.

Consult your AVSpare dealer for additional information.

Angle of the Heel




    Illustration 6g01600075

    Typical Example

  1. Place a measuring device in the top inside area of the heel on top of the blade. Ensure that the measuring device is held flat against the blade in order to acquire an accurate measurement.



    Illustration 7g01600076

    Typical Example

  1. Move the upper arm of the measuring device toward the face of the shank. Ensure that the measuring device is held flat against the face of the shank in order to acquire an accurate measurement.

  1. Check the angle that was measured with the device for the angle of the heel.

  1. If the angle is between 87 degrees and 93 degrees, the fork tine can remain in service.

  1. If the angle is less than 87 degrees or greater than 93 degrees, the fork tine must be taken out of service. The fork tines must be inspected for the following conditions:

    • permanent deformation

    • stress cracks

    • other defects

Consult your AVSpare dealer for additional information.
