Vehicle Restraints
Prevent the most dangerous loading dock accidents — trailer creep, early departure, and landing gear collapse.
Vehicle Restraints
Vehicle Restraint System
Automatic Rotary Hook Restraint with PLC Interlocking.
REDA vehicle restraints use a rotary hook mechanism to securely engage a truck's ICC bar (rear impact guard), preventing trailer creep, early departure, and trailer tip-over. When integrated with the REDA PLC control system, the dock leveler cannot operate until the restraint is engaged — a critical safety interlock.
Key Features
Rotary Hook Engagement
Positive mechanical lock on ICC bar. Prevents trailer creep, early departure, and landing gear collapse.
PLC Safety Interlocking
Dock leveler stays locked until restraint is engaged. Overhead door and dock shelter can be integrated.
LED Signal System
Inside (green/red) and outside (green/red) LED lights communicate dock status to forklift drivers and truck drivers.
DC 24V Safety Voltage
Low-voltage control circuit ensures operator safety. All electrical components meet UL standards.

⚠️ Safety First
Never operate a dock leveler without an engaged vehicle restraint. REDA PLC interlocking systems ensure the dock leveler stays locked until the restraint is securely engaged. LED light communication (green = safe, red = do not proceed) keeps truck drivers and forklift operators in sync.
FAQ
What ICC bar height range does the THM-800 cover?
The THM-800 vehicle restraint accommodates ICC bars between 230 mm and 762 mm (9–30 in) above ground level.
Can the restraint operate without the REDA PLC system?
Yes. The restraint can operate standalone with its own push-button controller. PLC integration is optional for interlocked safety with dock levelers and overhead doors.
What is the restraining force rating?
14,500 kg (32,000 lb). The forged 65Mn steel hook provides positive mechanical lock on the ICC bar.
