Replacement of the positioning lock and/or the marking, shall only be returned to service after being submitted to and passing, the testsĭescribed in paragraph 7.23.7, except that the test load shall correspond to 2.5 times the rated capacity marked on the fork.”ĪNSI/ITSDF B56.1-2009 6.2.8.1 Repair and Testing “A fork that has undergone repairs other than repair or If the fork is load tested and re-stamped with the new capacity. Key Inspection Points Fork wear calipers can also:įrequently Asked Questions Question: If the blade thickness is at 90% or less, can I place the fork on a lesser capacity unit?Īnswer: Yes. Note: Wear calipers are not recommended for full taper or lumber forks. The calipers measure the thickness of the fork arm shank (A) then automatically indicate what a 10% wear factor would be whentheĬalipers are applied to the blade cross section (B). Thickness, the fork shall not be returned to service.” (B56.1d-2009 6.2.8.1) If the thickness is reduced to 90% of the original Thoroughly checked for wear, special attention being paid to the vicinity of the heel. ANSI/ITSDF states “the fork blade and shank shall be Fork Wear Calipersįork wear calipers (p/n - A000025174) are used to check for wear and distortion. Forks must be properly seated on the carriage and the lock pins fully located in the carriage slot.įull Taper No Polish (FTNP) For smaller, shorter pallet skids.Using larger forks in demanding applications may Determine your fork wear cycle and replacement schedule for a specific operation.Obtain written approval from the fork manufacturer prior to making fork modifications.Make sure the capacity meets or exceeds the forklift rating and load weight.Inspect forks regularly, using an inspection log for recording data.Apply sideways pressure on forks, commonly called “side loading,” as they are designed for vertical loading only.Welding destroys heat treat properties, making the fork brittle. Repair or modify forks in the field, especially by welding.Use fork extensions that exceed 1.5 times the fork blade length.Use a fork in an application for which it is not designed.Overload forks beyond the rated capacity.Change forks from one forklift to another, without knowing the capacity of each.Carry full or partial loads on one fork.7.27.3 reflects manufacturing standards.įork Use Guidelines To avoid potential damage and injury DO NOT: 7.27.3*, except that the test load shallĬorrespond to 2.5 times the rated capacity marked on the fork. A fork that has undergone repairs other than repair or replacement of the positioning lock and/or the marking, shall onlyīe returned to service after being submitted to, and passing, the tests described in para. Repairs necessitating resetting are required, the fork shall subsequently be subjected to an appropriate heat treatment, as necessary. It is not recommended that surface cracks or wear be repaired by welding. (g) Legibility of Marking (when originally provided)Ħ.2.8.2 Repair and Testing (a) Repair – Only the manufacturer of the fork or an expert of equal competence shall decide if a fork may be repaired for continued use,Īnd the repairs shall only be carried out by such parties. (e) Positioning Lock (when originally provided) (c) Fork Angle (upper face of blade to load face of the shank) Has been satisfactorily repaired in accordance with para. Any fork that shows such a defect shall be withdrawn from service, and shall not be returned to service unless it Least half the manufacturer’s rated capacity of the truck, and at the rated load center distance shown on the lift truck nameplate.įork inspection shall be carried out carefully by trained personnel with the aim of detecting damage, failure, deformation, etc., which When forks are used in pairs (the normal arrangement), the rating capacity of each fork shall be at Severe applications will require more frequent inspection.
