Overview
The document provides detailed information about the Global Wheel-Lok™ (GWL 2300) vehicle restraint system by Rite-Hite, designed to secure various trailer types at loading docks. It emphasizes versatility, reliability, and safety features.

Specifications
The GWL 2300 is a surface-mounted, powered Wheel-Lok system that secures trailers with or without rear impact guards. It features a high-strength steel locking arm that adjusts to different tire sizes, engaging the driver's side rear tire with a 20-inch high steel barrier. The system can resist pullout forces exceeding 32,000 lbs (14,500 kg).

Operation
The system operates by positioning the trailer between dual wheel guides, triggering the restraint to engage using the trailer's energy. The locking arm sizes the tire and rises to its full height. Engagement and release are controlled via a control panel, with communication lights indicating the status.

Construction
The restraint is constructed from structural and formed steel, with components metalized or painted for corrosion resistance. It uses a hydraulic cylinder powered by a 120-volt hydraulic power unit, and the wheel guides are painted safety yellow.
