dantheman52,
There are several mentions of the VHE on the UPS Safety Calendars each year. These calendars are posted on the Joint UPS/Teamster Safety Boards.
VHE stands for Variable Height Extendo.
They are commonly referred to as Extendos, UNL-16s and UNL-46s, sometimes just unloaders.
The original and main purpose of these is for lift/lower injury reduction in the unload area and not production as some say.
The ability to keep the work in the power zone by raising and lowering the VHE is the main safety feature to help prevent lifting/lowering injuries. (a feature rarely used or encouraged to be used by front line sups)
A VHE assists to unload the trailers efficiently while preventing injuries associated with lifting and lowering.
The unloader is supposed to raise and lower the extendo to maintain this equipment in his power zone.
Using a load stand is one of the listed requirements to safely use this equipment for packages above shoulder height.
Sincerely,
I
