There are three standard lengths of air/hydraulic powered dock leveler lips, 16”, 18", and 20". Â The length of dock leveler lip required depends on various factors including but not limited to:
The dock leveler lip is tapered narrower on the end that is positioned on the truck. This option was required more in the past when 7ft wide dock levelers were to be utilized and when trailers were generally narrower than today. Tapering of the lip reduces the effective width of the dock leveler and is not required in most cases.
Lip Hinge Grease Fittings
Lip hinge grease fittings facilitate the application of grease to the dock leveler lip hinge.
