Lock-Up Vehicle Restraint - Vertical Barrier Position Dock Restraints

The patented NOVA Lock-Up™ Vehicle Restraint is designed to secure an intermodal container chassis, standard trailers, and most RIG bar configurations, including styles with cover plates
or other obstructions. It features a vertical barrier that secures the trailer’s rear impact guard, helping reduce the risk of premature departure and trailer creep during loading and unloading. Its spring-loaded housing lowers when the truck makes contact, while the carriage automatically adjusts to accommodate trailer float. The roller slope extension features a wheel assembly that rolls smoothly over the pavement to help prevent marks or gouges on the dock approach surface.

Mounts to dock above ground level to stay clear of accumulated precipitation and debris. Protected from the elements with watertight connectors and zinc plating, which provides exceptional corrosion resistance.

Vertical barrier position ensures engagement with intermodal containers and trailer RIG configurations with cover plates or obstructions
Patented activation system ensures RIG/barrier engagement when electrical power is lost
Brakeless, direct drive gear motor specifically engineered for this application—no brake, clutch, sprockets, chain or adjustment required
Designed to accommodate the widest variety of RIG configurations
RIG sensor is standard and will notify dock attendant when trailer is present without opening the overhead door
LED lights are standard for energy efficiency and longevity
Meets and exceeds ANSI MH30.3 requirement, tested and certified

FEATURES AND BENEFITS

The Lock-Up™ restraint maintains contact with the Rear Impact Guard (RIG) and adjusts automatically with trailer float motion to ensure proper engagement at all times during the loading and unloading process
Exclusive vertical barrier lifting mechanism utilizes a patented over-center device that maintains engagement even in the event of a power failure
Roller slope extension reduces/eliminates gouging/marking on the dock approach compared to “skid” style slope extensions
Non-contact magnetic proximity sensors provide robust, high-durability, and long-lasting performance
The gear motor operates on electrical current only when engaging or disengaging the vertical barrier with the RIG, resulting in more reliable operation and ultra-low energy cost
PLC-based control box with integrated maintenance diagnostics; option with CB-40/41
Slim profile carriage design reduces the risk of collision damage to the Lock-Up™ or truck trailers
CB-00 control box enables interlocking of the dock leveler, door, and gate
Includes a 5-year warranty

EXCEPTIONAL VERSATILITY – Low profile 9-inch carriage works with all standard trailers.
Engagement range extends from 9 to 31-inches above the ground.

ROBUST PERFORMANCE & DURABILITY – Exceeds ANSI MH30.3 requirements and features watertight connectors and corrosion-resistant zinc plating.

RELIABLE – Designed to withstand a pull-away force of over 32,000-pounds to prevent dock walk, premature departure and vertical trailer movement.

EASY TO USE – The spring-loaded carriage lowers with truck contact, and the restraint is operated by a control panel mounted inside the building.

OPERATION

As the trailer backs into position, the RIG contacts the spring-loaded structural steel housing, which rides down in its track and allows the RIG to move over the top of the housing. The dock attendant pushes the RESTRAIN button, which activates the vertical barrier to secure the trailer to the dock.
The Lock-Up™ restraint maintains contact with the RIG and adjusts automatically with trailer float motion to ensure proper engagement at all times. If there is a cover plate or obstruction above the rear impact guard, the vertical barrier adds an additional level of safety providing secure engagement. An
activation system ensures RIG/barrier engagement when electrical power source is lost. After service is complete, the dock attendant pushes the RELEASE button. If a trailer’s RIG is missing or damaged, the Lock-Up™ will communicate a fault condition. An audible alarm and flashing red light alert the operator that the trailer has not been properly secured. The operator may then override the fault condition and
secure the trailer by other means. The communication system automatically adjusts to reflect the current operational mode.

STRUCTURAL

The vertical barrier weldment can withstand a pull-away force of over 32,000-pounds and is a lamination of two 2 3/4 x 3/4-inch thick ASTM A572 Grade 50 steel plates with 1-inch ASTM
A36 steel spacers in between. The vertical barrier weldment is located within the carriage between the two side plates. The carriage side plates are constructed from abrasion-resistant 200F steel for maximum defense against wear from contact and friction with the RIG. The 1 1/4-inch diameter carriage axles and 2 5/16-inch diameter rollers are both made from cold-rolled 1045 steel. The roller track is formed out of ASTM A572 Grade 50 steel into a 6 3/8 x 3-inch channel with 7/8-inch flanges. The roller track is attached to the dock face with 15 heavy-duty sleeve anchors that each measure 5/8 x 4-inch long.

ELECTRICAL

All operator controls are mounted in a control panel that remains fully operational at all times. Specially engineered electric motor and limit switches are enclosed in an abrasion-resistant structural steel housing. Electrical components and wiring are UL listed® or Recognized®. The Lock-Up™ restraint
requires a power source of 110/115 volt, single-phase with a 15 amp service circuit.
