The owner should, therefore, train and instruct operators in the safe use of dock leveling devices. When a transport vehicle is positioned as closely as practical to a dock leveling device, there shall be at least 4" of overlap between the front edge of the lip and the edge of the floor or sill of the transport vehicle. Nameplates, cautions, instructions and posted warnings shall not be obscured from the view of operating or maintenance personnel for whom such warnings are intended. Manufacturer’s recommended periodic maintenance and inspection procedures in effect at date of shipment shall be followed and written records of the performance of these procedures should be kept. Dock leveling devices that are structurally damaged or have experienced a sudden loss of support while under load, such as might occur when a transport vehicle is pulled out from under the dock leveling device, shall be removed from service, inspected by the manufacturer’s authorized representative, and repaired as needed before being placed back in service. The owner shall see that all nameplates, caution and instruction markings or labels are in place and legible and that the appropriate operating and maintenance manuals are provided to users. Modifications or alterations of dock leveling devices shall be made only with written permission of the original manufacturer. When industrial vehicles are driven on and off transport vehicles during the loading and unloading operation, the brakes on the transport vehicle shall be applied and wheel chocks or positive restraints that provide the equivalent protection of wheel chocks engaged. The dock leveler should never be used outside its vertical working range or vertical lifting range or outside the manufacturer’s labelled rated capacity. It must also be compatible with the loading equipment and other conditions relating to the dock. 4 6004751K — aFX® and aFX-S Dock Leveler — SafeTFrame® August 2012 ©2012 4Front Engineered Solutions, Inc. raMp anD Lip graDeS Fig. 1 Ramp grade Lip grade VEHICLE RAMP and LIP grades, % for each dock leveler length VEHICLE RAMP and LIP grades, % for each dock leveler length PLATFORM PLATFORM POSITION from 6' Leveler 8' Leveler 10' Leveler POSITION from 6' Leveler 8' Leveler 10' Leveler DOCK, (in.)
