New Vehicle Restraint Prevents Drive Aways

Salvo™ Chock quick and easy to use

Chicago, Illinois  – Industrial safety specialist Castell’s interlocking wheel chock, Salvo™ Chock is specifically designed for restraint of straight trucks and other vehicles that cannot be locked out with a Salvo glad hand lock. Ideal for demanding loading yard conditions, the chock is light, strong, easy to use and fast to maneuver.

The Salvo system restrains vehicles at loading docks during loading or unloading. Its technology uses safety interlocking to eliminate human error and enforce safety procedures. If the Salvo Chock is not properly fitted, the loading dock door cannot be opened.

Drivers position the chock and clamp the two halves together around the wheel using a convenient foot pedal, releasing the trapped key. The key is then transferred to the loading dock control panel, allowing the loader inside the warehouse to open the door and begin safely loading or unloading.

To remove Salvo Chock, the loader must first close the loading dock door. The driver can then remove the key from the control panel and return it to the chock. Inserting the key unlocks the chock and traps the key until it is again properly fitted on a tire.

Launched eight years ago to prevent drive aways in the logistics industry, the Salvo range has grown to address key market needs. It includes manual and automatic door systems, brake line locking options, accessories and a new efficiency enhancing software program. DockMonitor software captures operational data such as loading time, number of operations, idle time and available time measure performance while still guaranteeing safety.
