Vehicle Detection Solutions Provide Enhanced Safety and Efficiency

Safety Benefits and More
The risks inherent in dock area operations make it worthwhile to define and implement dock safety procedures and, when necessary, safety equipment improvements. Dock safety policies should be revisited periodically and updated to reflect operational changes, growth, and new & better ways of doing things.
Vehicle detection solutions can be an important part of any organized dock safety program. The four leading types of vehicle detection methods are photo eyes, safety edges, loops, and motion sensors.
Nothing is more important than the safety of your people, products, and equipment. But beyond safety value, vehicle detection solutions can help streamline traffic, save time and increase productivity within a facility. Whether for regulatory compliance, enhanced safety, or long term ROI, vehicle detection solutions make a compelling value proposition.
Electronic photo eyes are placed at opposite sides of a door on the inside of the building. They control a door’s motion by sending a light signal or “through-beam” between each eye. If the beam is broken, the door goes up and will not close. The two types of photo eyes are retro-reflective and transmitter-receiver.
With a retro-reflective solution the light beam bounces back & forth between the transmitter and receiver. A vehicle or other object is sensed when the beam is broken and fails to reach the receiver. A transmitter-receiver solution has a transmitter photo eye on one end and a receiver photo eye on the other end. Since its light beam is continuous and one directional, transmitter-receiver photo eyes work across greater distances.

Safety edges or “sensing edges” are attached to the bottom edge of a sectional or rolling steel door. When the edge makes contact with something, the door’s downward motion will stop and the door will go up. This is a standard safety feature on high-cycle doors. Sensing Edges can be used in hundred of commercial and industrial door applications because they can accommodate a wide variety of door heights, widths and lengths.

Loop vehicle sensing solutions are embedded under the surface area on both sides of a door. The in-ground loop uses a magnetic force field to detect when a vehicle is moving over it. It can then open & close the door automatically, increasing traffic efficiency, saving time, and reducing energy loss.

Motion sensors work by detecting motion within the sensor’s immediate range. Motion sensors are typically installed above a door and integrated with the motor so that the door opens when a vehicle approaches. Motion sensors can tell whether a vehicle is moving toward or away from a door, and can accommodate two-way traffic. Some sensors can even tell the difference between pedestrian and vehicle traffic.

Reaping the Safety & ROI Benefits of Vehicle Detection Systems
Look for areas of your dock operation where integrating a vehicle detection system can improve safety and efficiency. Engage an experienced dock solutions vendor who will actively consult with you on equipment replacement and upgrade scenarios based on your unique operational needs and the life expectancy of your current systems. The safety & ROI benefits of vehicle detection solution innovations in your operation can be realized for years to come.
