OmniLock™ Vehicle Restraint | Nova Technology Loading Dock Equipment

The NOVA OmniLock™ is a rotating hook-style vehicle restraint featuring an innovative patent-pending design to release RIG Wedge. RIG Wedge occurs when a trailer is pushed forward during loading or unloading, applying excessive pressure to the restraint’s hook from the trailer’s Rear Impact Guard (RIG). As a result, the truck driver must reverse the trailer to release the restraint. The newly designed hook operating mechanism allows the restraint to overcome RIG Wedge by relieving pressure on the hook when it disengages from the trailer’s rear impact guard, allowing the hook to rotate down. The OmniLock™ also utilizes a secondary engagement zone to securely restrain RIGs with plates, including Intermodal chassis.

The OmniLock™ has a vertical engagement range of 9 to 31-inches (220 to 787-millimeters) and mounts to the dock face above ground level to stay clear of accumulated precipitation and debris. Its elevated installation protects it from the elements, along with watertight connectors and zinc plating for added corrosion resistance.

FEATURES AND BENEFITS

Hook design enables the restraint to overcome “RIG Wedge” by relieving pressure on the hook from the RIG as it disengages
Secondary engagement mode safely and effectively restrains RIGs with plates including Intermodal chassis
Secures all standard RIG bars, including rectangular, pentagonal, 4-1/2″ reinforced RIG bars, and RIG bars with plates, including Intermodal chassis
Hook is rotationally upward biased and will continuously secure the RIG when a trailer shifts while restrained, even if power is lost
Hook extends when releasing to ensure proper disengagement from the docked trailer even when “RIG Wedge” occurs
Automatically resets hook if the trailer is not properly restrained
PLC-based control box provides maintenance diagnostics
Roller slope extension eliminates gouging and marking on the dock approach surface
Compatible with interlock and combination control boxes for integration with doors, gates, and levelers
Standard bypass and override feature is password-protected for use by authorized personnel only
LED Lights are standard for energy efficiency and long life
Includes a 5-year structural warranty

EXCEPTIONAL VERSATILITY: The OmniLock™ secures all standard types of RIG bars and RIGs with plates like Intermodal chassis. Its low-profile 9-inch carriage works with all standard trailers. Engagement range extends from 9 to 31-inches above the ground.

ROBUST PERFORMANCE & DURABILITY: The motor is IP67 compliant with watertight connectors and corrosion-resistant zinc plating.

RELIABLE: Withstands a pull-away force of over 38,000-pounds and helps prevent premature departure, trailer creep, landing gear collapse, trailer pop-up and trailer up-ending.

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

OPTIONAL FEATURES:

IntelliDock Combination control box
Open dock stanchion for control box
Articulated slope extension
Projection brackets and reinforcing plates
Green light interlock with leveler, door, or gate
Password protected hook release

OPERATION

As the trailer backs into position, the RIG contacts the spring-loaded 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 hook to secure the trailer to the dock. The rotating hook can withstand a pull-away force of over 38,000-pounds. The OmniLock™ restraint maintains contact with the RIG and adjusts automatically with trailer float motion to ensure proper engagement at all times. After service is complete, the dock attendant pushes the RELEASE button. In the event a trailer’s RIG is missing or damaged, the OmniLock™ will communicate a fault condition and auto-store the floating hook. An audible alarm and flashing red light alert the operator when a 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.

ELECTRICAL

All operator controls are mounted in a control panel that remains fully operational at all times. A specially engineered electric motor and sensor system are enclosed in a steel housing. Electrical components and wiring are UL Listed® or Recognized®. The OmniLock™ requires a power source of 110/115 volt single-phase with a 15 amp service circuit.

NOTE: Unless specified on quotation, NOVA Technology will not provide any conduit, disconnects, junction boxes or other electrical components.

STRUCTURAL

The Floating Hook can withstand a pull-away force of over 38,000-pounds. It is made from A514 Grade B steel and is driven with a 1 1/4-inch diameter shaft made from cold-rolled 1008 steel. 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.

COMMUNICATION SYSTEM

Outside Signal Lights: constant flashing red or green LED lights with signs instruct the truck driver when it is safe to back into or pull away from the loading dock.

Control Box LED Signal Lights: constant flashing red or green LED lights with signs inform the dock attendant when it is safe to perform loading/unloading operations.

Audible Alarm: in addition to the flashing red light and automatically storing the hook, the interior alarm warns the dock attendant when a RIG has not been properly engaged.

Horn Override: the customizable keypad allows authorized personnel to override the restraint using a programmable password. This causes the inside red and green lights to flash simultaneously while the outside red light flashes. Other products that interface with the restraint through either an interlock or combination control box are able to be operated as normal.

LED Lights: standard LED lights provide longevity and reduce electrical power consumption.
