Your first choice when quoting LEED certified projects. The Door Doctor U-Series vertical storing dock leveler is the perfect loading dock solution for facilities and applications that require strict climate control or high cleanliness levels. It improves internal temperature control, reduces the risk of door damage, and minimizes debris entry. Trailers typically back into the specially designed loading dock bay and before the doors are opened allowing for contamination, a complete seal is formed between trailer and inside the facility.
Studies on application: Companies actually lose one ton of refrigerate air per dock door per year, on average, when they use pit levelers instead of vertical dock levelers. The concept of ‘drive–thru’ applications where the added efficiency, and virtually no loss of refrigeration is appealing. The trailer backs directly to the loading dock and the trailer doors are opened into the building rather than the traditional opening of the doors prior to fully backing into the position.
The U-Series vertical storing dock leveler is controlled by the adequate Control Panel, with an interior and exterior LED lights communication system available as an option. Operating range is up to 12” (305mm ) above and 6” (305mm) below dock level. The unit comes complete with a 1HP, Totally Enclosed Non-Ventilated (TENV) power pack system.
