Unmatched Loading Dock Safety: Wheel-Lok Vehicle Restraints

Wheel-Lok restraints provide the highest level of safety for the application. Wheel-Lok restraints service a variety of trailer types, such as trailers with hydraulic liftgates, dropframe trailers and trailers without an effective rear impact guard (RIG). Full-time communication of the Wheel-Lok status is provided with the Rite-Vu Light Communication System.

When to use a wheel-based restraint

Wheel-based restraints are effective in the following situations:

  • Trailers without NHTSA-approved RIGs.
  • Trailers with damaged or bent RIGs.
  • Trailers with hydraulic lift gates.
  • Trailers with low-hanging fenders.

Case Study


This customer had a unique dock layout that was originally outfitted with a competitor's vertical barrier vehicle restraint In addition to reliability issues, the customer was having trailer/dock separation issues multiple times a year, resulting in costly product damage and a real safety concern.


Pugleasa evaluated the operation and environment with the customer and ultimately installed an STR-4100 Dok-Lok Restraint that stabilizes the trailer and with a rotating hook design that securely entraps the trailer’s rear impact guard under the most challenging of dock conditions. 


This product has eliminated the trailer separation issues and provides a safer working environment.  After trying one STR-4100, this customer had Pugleasa install eight more units. Pugleasa Company has been helping customers address loading dock safety issues and improve loading dock safety for over 50 years. Contact us today with your situation.
