Loading Dock Equipment

Name: Dock accessories
Brand: Overhead Door

Dock doors, dock levelers, seals, shelters, and restraints, sold and serviced as one family.

We install and service every loading dock from Century Avenue using our own crews across 11 Maryland counties. A dock is a system: the door, the leveler that bridges to the trailer, the seal or shelter that keeps weather out, and the restraint that holds the trailer. We handle the entire position so one call covers it all.

Overhead Door dock equipment carries a one-year limited warranty. This extends to two years when the leveler, seal or restraint is bought together with the door.

Hydraulic pit leveler

Models H68R and H78R

Models H68R and H78R are hydraulic pit levelers built for performance and designed for installers. A beveled lip and a level deck provide a smooth building-to-truck transition. This cuts shocks to forklift operators and damage to cargo. A textured powder coat keeps traction on the deck when it is wet. Downtime stays low. The multi-lug hinge sheds debris. The full-width rear hinge spreads the load across the deck instead of a few points. The powerpack sits protected behind the center-mounted cylinder. They are rated 30,000 to 45,000 lb CIR with single-button operation. They meet ANSI MH30.1-2022 with a 10-year structural rating. It is the leveler our crews install most often at distribution docks around Baltimore.

Mechanical pit leveler

Models M68R and M78R

Models M68R and M78R are mechanical pit levelers. They share the same deck, lip and pit frame as the hydraulic units, but operate by pull chain and spring counterbalance. No electrical service is needed at the position. They install fast and safely. Height adjusters are worked from the building floor, so the installer is never under the leveler. Cutouts mark the weld points on the curb angle. They are rated 30,000 to 45,000 lb CIR, and are end loading and below-dock capable. Working-range toe guards are standard, with full-range guards optional. They feature the same textured powder coat and debris-shedding hinge as the hydraulic line. They meet ANSI MH30.1-2022.

At a glance

Models: M68R (6 ft wide), M78R (7 ft wide), both 8 ft long
Capacity: 30,000 to 45,000 lb
Best for: Steady docks with no power at the position
Operation: Mechanical, pull-chain release; no electrical hookup
Standard: ANSI MH30.1-2022

Edge of dock leveler

Models E66R and E72R

Models E66R and E72R are face-mounted edge of dock levelers rated at 20,000 and 30,000 lb CIR. They are made for a smooth building-to-truck transition with fewer bumps, gaps and jolts to workers and equipment. Deployment is by a push-pull handle that keeps the operator upright. They have a 5 in operating range above and below dock, and return to stored position if the trailer pulls away. The lip hinge sheds debris. The deck and lip carry a textured powder coat for traction and corrosion resistance. Mounting options include approach plates, wall plates, formed angles and channel embeds. They meet ANSI MH30.1-2022. Because there is no pit to cut, it is the quickest dock upgrade our crews do.

Models: E66R (66 in wide), E72R (72 in wide)
Capacity: 20,000 to 30,000 lb
Best for: Captive fleets, cost-effective docks

Trailer restraints

Model RTPI10R

The Model RTPI10R is a permanently mounted, electric mechanical vehicle restraint that reduces the risk of dock accidents. A high-visibility rotating hook engages the trailer's rear impact guard with 32,000 lb of restraining force. It tracks trailer movement during loading. It is virtually maintenance-free, with no mechanical limit switches. A waterproof position sensor monitors the hook, and pulse width modulation motor control extends motor life. Inside and outside LED lights, an LCD display, and an audible alarm signal status to the driver and the dock. Interlock options tie restraint status to the leveler lip and door position. Our crews wire these interlocks in when the dock is installed as a system.

Model: RTPI10R, powered impact restraint
Operation: Electric, push-button; hook tracks trailer movement
Signals: Inside and outside LED lights, LCD status, audible alarm
Interlocks: Optional leveler lip and door position

Fixed dock seal

Model LX10R

The Model LX10R is a compression dock seal. When the trailer backs in, the foam top pad and side columns compress to create a tight seal. This holds conditioned air in and keeps weather out. The columns and pad use premium-grade foam with full compression and recovery down to -40 F. They are bonded to the backing with a non-flammable elastic adhesive. Plated vents drain moisture and relieve air on compression. The fabric is fire resistant, UV treated and double stitched. It is available in 22 oz and 40 oz weights. A premium 40 oz option carries six times the abrasion resistance. Column wear pleats are available where trailer impact is heavy.

At a glance

Model: LX10R
Size: 8 ft columns standard (7 ft 6 in and up); top pad 6 ft 4 in to 11 ft wide
Best for: Docks serving trailers of a consistent size
Construction: Fire-resistant foam core, UV-treated fabric, vented columns
Fabric: 22 oz and 40 oz weights; premium 40 oz for abrasion
Warranty: 1-year limited

Adjustable curtain seal

Model LC20R

The Model LC20R is a compression seal with an adjustable top curtain. One position can seal trailers of varying heights, keeping the heating and cooling cost of an open dock down. The curtain rides a full-width steel tube on a rope and pulley assembly with drops up to 60 in. Low-temperature PVC strips can replace the curtain fabric for cold storage. The columns are premium-grade foam with the same -40 F compression and recovery rating. The fabric is fire resistant and UV treated. Optional wear pleats and a bottom seal pad add impact protection and four-sided sealing where there is no leveler. For the mixed box-truck and 53 ft trailer traffic most Baltimore distribution docks see, this is the seal we recommend.

Model: LC20R
Size: 10 ft columns standard (9 ft 6 in to 12 ft); curtain drop up to 60 in
Best for: Docks serving trailers of varying heights

It keeps weather out and heating and cooling costs down, while leaving the full width and height of the trailer open for loading. The side and top panels are clad in galvanized steel trimmed with aluminum angle. The top is peaked to drain water. Both upper corners carry overlapping wear pleats against trailer impact. The fabric is fire resistant, UV treated and double stitched. Premium and premium plus grades are available for the hardest service. Standard size is 11 ft 6 in wide by 11 ft high, extendable up to 12 ft 8 in by 12 ft 6 in.
