Lock & Load Vehicle Restraint - Hook Style Loading Dock Restraints

WHAT YOU SHOULD KNOW ABOUT NOVA’S LOCK & LOAD™ VEHICLE RESTRAINT

The NOVA Lock & Load™ is a hook-style vehicle restraint that secures the trailer’s rear impact guard (RIG) at the dock to reduce the risk of premature departure and trailer movement during loading and unloading. Its spring-loaded housing lowers with truck contact, and the carriage automatically adjusts with trailer float. The Lock & Load™ has an enhanced design with a patented Triple Range Hook that outperforms competitor hook-style restraints:

Secures RIG bars that are rectangular, pentagonal and feature 4 1/2-inch vertical center plates
Triple Range Hook safely secures RIGs while the hook is at various heights
Elevated hook shank maintains engagement and eliminates false-negative RIG bar sensing from gaps created by carriage bounce
Exclusive gear motor with a one-way braking system keeps the hook continuously engaged
Hook is upwardly biased and rotates to increase engagement if contacted by the RIG when trailer shifts during loading and unloading

FEATURES AND BENEFITS

Roller slope extension eliminates gouging and marking on the dock approach surface
Gear motor operates for a total of three seconds from the full cycle of restraining and releasing a vehicle
Only uses electricity when engaging or disengaging the rotating hook
Hook maintains engagement with the RIG, even if power is lost
PLC-based control box with integrated maintenance diagnostics; optional with CB-20/21
Control box includes keypad for override as standard
LED lights are standard for energy efficiency and long life
Non-contact frictionless system
Includes a 5-year warranty

EXCEPTIONAL VERSATILITY: The Triple Range Hook secures RIG bars that are rectangular, pentagonal and feature 4 1/2-inch vertical center plates. 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 32,000-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.

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 hook to secure the trailer to the dock. The rotating hook can withstand a pull-away force of over 32,000-pounds. The Lock & Load™ 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 Lock & Load™ will communicate a fault condition. 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. Specially engineered electric motor and limit switches are enclosed in a structural steel housing. Electrical components and wiring are UL Listed® or Recognized®. The Lock & Load™ 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 rotating hook can withstand a pull-away force of over 32,000-pounds and is machined from 1 1/4-inch thick A514 Grade B steel plate and 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.
