or shelter all meet. Depending on the size of
the opening, that gap can result in another
US$200 to US$900 of energy waste, annually.
SEALING THE PERIMETER
Besides being regimented in keeping loading dock doors closed when trailers aren't
secured for loading/unloading, one of the
best ways to keep detrimental contaminants
like rain out-and conditioned air in-is to
address the perimeter of the dock door. This
can be achieved with a loading dock seal or
shelter, which creates an environmental barrier between the back end of the semi-trailer
and the outside border of the dock opening.
An effective dock sealing system helps
prevent weather-related product damage and
contamination, protecting and securing the
integrity of products as they move in and out
of a facility during manufacturing, processing,
and shipping.
DRIVE-THROUGH DOCK DESIGN
Increasingly, managers of all types of manufacturing plants are realizing that drive-through
dock configurations are the "gold standard" for

environmental control and energy efficiency.
Drive-through dock applications are designed
with a recessed pit and vertical-storing levelers, which allows trailer doors (and security
seals) to be opened inside the loading dock,
eliminating exposure to outside precipitation.
Drive-through docks are better from a safety
and efficiency standpoint as well, since neither
the driver nor the dock employees need to go
outside and open the back of the trailer before
it fully backs in and is secured to the dock wall.
Vertical levelers also have maintenance
advantages. Unlike pit-style levelers, vertical
levelers store up and out of the way, making it
easier to clean them and wash down the floor.
Moreover, vertical levelers (when in the stored
position) allow the dock door to close directly
onto the pit floor for a more water-tight seal.
Recently, dock shelters have been developed
specifically for drive-through applications to
work in tandem with vertical levelers. Thanks
to special design features, these shelters ensure
tight sealing against trailer sides, across the
full width of the trailer top and at the corners,
without interfering with trailer doors being
opened and closed after the trailer has been
parked and secured at the dock. When paired
with the appropriate under-leveler dock seal, a
superior four-sided closure is created around
the entire dock opening.
AUTOMATING SAFETY AND EFFICIENCY
Operational efficiency and employee safety
can also be enhanced through automated dock
control systems. Most loading dock operations
at paper mills require workers to operate various
pieces of loading dock equipment (including

vehicle restraints, levelers and overhead doors)
independently of each other. This can lead to
various human errors that may damage product or, even worse, cause injuries. However,
with today's dock control systems, facilities can
ensure the equipment on their dock can only be
engaged through a safe sequence of operation.
For instance, the most advanced systems can
be programmed with a green light interlock,
which disables the use of the hydraulic leveler
or overhead door until the vehicle restraint is
safely engaged; an overhead door interlock,
which requires overhead doors to be opened
prior to leveler operation; or a stored leveler
interlock, which ensures that the leveler is stored
safely before the restraint can release the trailer.
If a worker presses the control box button for
an individual system element in the wrong
sequence, it won't work. This control box helps
ensure that no safety procedures will be skipped.
Regardless of the interlocking system (if
any), the first step in securing the trailer as
part of a drive-through operation is engagement of the vehicle restraint. Rotating hook
restraints that secure trailers by the rear
impact guard (RIG) have become ubiquitous
at North American loading docks. However, in
response to the increased prevalence of intermodal cargo and a growing diversity of trailer
configurations that have an obstructed RIG,
the newest restraints incorporate "shadow"
hook technology. This type of hook provides
an additional pivot point capable of securing
trailer chassis with obstructed RIGs. These
automatically activated restraints can also be
integrated into building management or security systems and are upgradeable to include
additional audio and visual communication
cues for increased safety at the loading dock.
PROTECTING PRODUCTS AND
WORKERS AT THE LOADING DOCK
Quality paper starts with a clean, dry operation. Even the loading dock, a traditionally
damp and unclean place, can be made much
cleaner with a systematic drive-through design.
Vertical dock levelers, appropriate seals/shelters and the latest vehicle restraint can combine
to reduce contamination and energy waste,
help protect employees, and even enhance the
integrity of the overall supply chain.
