Poweramp VS-Levelers

vs_1Poweramp VS series dock levelers, store in the vertical position to conserve warehouse space, and to limit the loss of conditioned air from refrigerated warehouses. The levelers design allows the over-head door to form a tight seal with the pit floor, eliminating energy loss due to gaps formed by the equipment and the building.

The Poweramp – VS vertical storing leveler not only saves space but it also increases dock security and protects other facilities equipment. In the stored position, the leveler is a natural barrier, helping to prevent damage to over-head doors and door tracks. Having no framing members, the VS-series leveler provides for convenient cleaning of the pit floor.

PowerHook® Series Automatic

powerhook_lgThere are many components that ensure a safe material handling operation. One of the most important is an effective, dependable truck restraining system like the PowerHook® by Poweramp.

The PowerHook® restraint by Poweramp is the elite restraining device available on the market. By actively seeking, finding, and securing a trailer’s “Rear Impact Guard” (RIG), the PowerHook® eliminates potential problems between the truck and the dock leveler.

The PowerHook® restraint is firmly anchored in the loading dock pit for maximum holding strength. The hook remains recessed and protected behind the pit wall until activation, making it easy to maintain the dock exterior. Because it stores in the pit, the restraint is completely concealed and out of the way. This is a great advantage when clearing the drive approach of snow or debris.

The PowerHook® is designed to withstand a pulling force in excess of 35,000 lbs, providing an extra margin of safety and protection. This restraint has the widest service range in the industry with a horizontal range of 0” to 15” from the building and a vertical range from 7” to 34” off the drive. Extended ranges are available for special applications.

With over 10,000 applications over a twenty year period, the durability and reliability of PowerHook® is unmatched in the industry. Be sure to specify the “original” PowerHook® on your next loading dock application.

Dock Sealers

Dock Seal with Head Pad

Model DS

dixie dock seals
Dixie Dock Model DS Dock Seal provides maximum energy savings in a weather tight enclosure. When seals are compressed properly they form an effective seal that retains cool air or heat and blocks dust, rain, wind, snow, and fumes from entering the dock area.

Dixie Dock Seals are constructed with durable high quality vinyl coated fabric with resistance to wearing, tearing, and the elements. We use a highly resilient polyurethane foam to help maintain the pads shape. The pads are mounted on kiln dried pressure treated wood backing for longer life. All pads are vented with brass grommets for air and moisture release. A 4″ guide stripe the entire height of the vertical pad is standard. All installation hardware is included with seals.

Options: 18″ or greater Head Pad to accommodate taller


Dock Seal with Head Curtain

Model DS/F

dixie dock seals2Dixie Dock Model DS/F consists of two vertical side pads and a full width head curtain which will accommodate a variety of truck heights. This model is manufactured with the same materials and design as the DS model. Tapered top is mounted on a pressure treated 2 x 4 atop the vertical side pads and affixed to the wall of the building.

Our non-sagging design utilizes a 3/4″ galvanized pipe for front edge support. Stays provide for support in the top of the curtain. The curtain is held tight by straps on each end. Head Curtain models are suitable for door openings over 9′ high.

Options: Split curtain with Velcro. Adjustable rope pulls to allow adjustment of curtain height. Foam sewn in face of curtain.


Rigid Dock Shelter

Model RS

dixie dock seals3Dixie Dock Model RS Rigid Frame Truck Shelters are mounted directly to the building allowing trucks to back into them. The top and side curtains flex inward with a wiping action, forming a seal on the outside of the trailer. This allows full access into the rear of the trailer. The top of the shelter is sloped to prevent water from standing on top. Steel bumpers are used to protect the shelter.

Wear pleats are added to the curtain to help absorb the impact of the corner of the trailers. Wear face on bottom corners of verticals absorb impact of trailers corners. Tapered draft pads behind side curtains help decrease air flow.



Insect Barrier Screen


Dixie Dock Insect Barrier Screen offers protection from flying insects, birds and rodents, while allowing fresh air to be circulated throughout your facility. It also provides security against unauthorized visitors and intruders. Insect barrier screens are available in sliding, spring loaded and motorized roll up models. The vinyl coated polyester mesh fabric permits air and light to enter your facility, and helps turn the dock area into a safe, comfortable work environment.

The mesh fabric is fire retardant and mildew resistant. Applications for insect barrier screens are found in food processing, storage, and production facilities; as well as dairies, pharmaceutical and baking industries.

Options & Features

  • Wedged side pads or cube side pads – to provide effective sealing when doors are wider than normal truck door.
  • Tapered seals for incline / decline docks
