Preparing Your Loading Docks for Winter

In northern geographies and colder climates, the winter can wreak havoc in loading dock areas. Not only does temperature control become more difficult, snow and ice that gets inside a facility can damage product and become a serious slip risk for workers.

Let’s look at some of the biggest culprits of energy loss and safety risks associated with winter weather at the loading dock.

Light Means Trouble

Any light that is visible through gaps between a secured trailer and the loading dock door means outside air and elements can get inside. Snow, cold, rain and ice can – and will – sneak through these openings and create problems for loading dock workers and the materials they handle

Additionally, the warm conditioned air inside the loading dock can leak out of the facility, causing HVAC systems to run harder than necessary to make up for the heat loss. It’s no coincidence that energy usage often soars during the winter months in colder climates.

Before any solutions can be considered for these potentially costly and hazardous gaps, it’s important to see exactly where light (and any outdoor elements) are coming through.

Common Gaps at a Loading Dock Opening

Fortunately, these gaps are fairly obvious and often predictable in location. They are:

  • Along both sides of the trailer (often in trailer door hinge gaps)
  • At the top of the trailer
  • Below and around the loading dock leveler and dock bumpers

Once these gaps are identified, the right solutions can be evaluated.

The Right Equipment

In some cases, it’s just a matter of replacing old or worn-out sealing products. Eventually, loading dock seals, shelters, and filler pads diminish to the point of being ineffective. Fortunately, there are some easy-to-find replacements or upgrades that can perform admirably.

Depending on the application, a loading dock seal or shelter can help provide valuable sealing power along the sides and tops of most loading dock openings. It is estimated that sealing air gaps at the loading dock can help save up to $5,000 annually per dock position. Additional products can help seal the “fourth side” of the loading dock opening near the floor, such as under-leveler seals.

Performing an inspection on your exterior door seals and cycle times will also help you prepare your facility for colder temperatures. Each loading dock door opening represents a giant hole in the wall of your facility. Strung together, these dock openings present an enormous opportunity for heating energy to escape – not to mention allowing rain/snow, dirt and pests to get in. Improving your loading dock door weather seals can help save up to $7,000 annually per door opening.

Other things to consider while preparing your facility for winter include improving interior air movement. By adding HVLS industrial ceiling fans to your facility, you can help save 20-30% on heating costs per year. The fans are designed to circulate a large amount of air in a process known as destratification. This process mixes warm air from the ceiling with cooler air at the floor, to even the temperature throughout the space.

Bonus Winter Tip: if snow accumulation on the tops of trucks and trailers is a concern, check out these effective snow removal systems.

Prepare Your Loading Dock for Winter

Make sure no light – and thus weather – is getting inside the loading dock by examining your loading dock door openings. Once gaps have been discovered, ensure they’re eliminated by installing proper equipment. Then, consider other areas of the facility that might benefit from the installation of industrial fans or snow removal systems. At Rite-Hite, we have trained representatives who can perform an audit on your facility for energy improvements. They can help identify areas in your warehouse or distribution center that are prone to energy loss. For help getting started on winterizing your loading dock, contact Rite-Hite for a site survey.
