What is Auto Return on a dock leveler?

Auto Return is only available on hydraulic dock levelers. When the truck is backed into position and the trailer doors are open the dock attendant cycles the dock leveler. The dock leveler deck raises, the lip extends, the dock leveler is then lowered and the extended lip is positioned on the truck bed. When the truck is loaded / unloaded typically the dock attendant would cycle the dock leveler into the closed, stored position. If there is no dock attendant available the truck driver departs, the dock leveler deck and extended lip lowers to the bottom position. The hydraulic lip begins to retract and an under deck electric limit switch is then activated. The dock leveler deck automatically raises approximately 6” – 8” above the dock height, the lift motor timer shuts off and the dock leveler returns to the stored position. When the truck departed the dock leveler was automatically returned to the closed, stored position.

Are lift table accordion bellows a safety device?

Although there is a common perception that accordion bellows are a safety device they are not promoted as such. The primary purpose of lift table accordion bellows is to prevent debris from getting under the lift table and interfering with the leg rollers, power unit etc. Many companies mandate that all lift tables within their facility be equipped with accordion bellows to prevent debris from getting under the platform and the yellow accordion bellows also serve as a highly visible signal that equipment is in motion.

What is Considered to be a High Cycle Lift Table Application?

The majority of lift tables are designed to be cycled 8 times per hour during an 8 hour shift, 5 days a week. In an application that needs more cycles than the standard amount, lift tables are recommended to be equipped with a high cycle package. A high cycle package consists of cam followers in place of leg rollers, spherical bearings in place of bushings, and often equipped with a central lubrication system. In addition to these components, high cycle lift tables are often specified with a continuous running power unit. A continuous running power unit is a power unit that keeps the motor running even when the lift table is not in use which eliminates any jog starting of the power unit resulting in pre mature wear.
