The interlocks are made entirely from stainless steel. Very low manufacturing tolerances are used in production, meaning that there are no differences in measurement at the tips, even with a fork blade length of 2400 mm, particularly in heavy-duty fork arms. Deflection is significantly reduced as a result of the construction (statics). The wear zone is coated with an extremely abrasion-resistant material. Plastic deformation first occurs at more than 4 times the nominal load.
