When researching for an article on front bumper extensions, more questions were created than facts were found. And they were only about front tow hooks and tow eyes. Sentence 12.3.5* Tow Hooks in the National Fire Protection Association’s NFPA 1901 Standard for Automotive Fire Apparatus states: “Front and rear tow hooks or tow eyes shall be attached to the frame structure to allow towing (not lifting) of the apparatus without damage.” That is short and simple–probably as brief as most purchasers’ specifications as noted below. There is a bit more to front-towing provisions that purchasers should consider.
Alissa McGlone, marketing manager for HME Ahrens-Fox, put me in touch with David Rider, director of product management & development for HME, who answered some questions on front-towing provisions, the differences between hooks and eyes, how and why they’re located, and how purchasers should specify them.
Do tow hooks and tow eyes have different “weight” ratings? Generally, no, because they have the basic job of providing an anchor point to attach a tow cable. They are only as stout as what they are bolted to and the strength of the fasteners. NFPA 1901 stipulates they are for towing only and not lifting the apparatus.
Eyes and hooks can be mounted on top of a bumper, underneath it, or through the front of it. Are mounting locations job-specific? Typically, tow hooks under the bumper are the standard. Sometimes it’s more about aesthetics than function with hooks being more hidden and eyes more in the open. They are there if needed, but typically play no other role. Tow eyes through the bumper, or above or below it, might be used as anchor points. In large fleets they might be specified to be compatible with a fleet-owned wrecker.
