Laser Line Projectors

How a laser line projector works

A laser diode shines through a lens that spreads the beam into a shape — a straight line, an arrow, a circle or an arch — and lays it on the floor. Because the light is concentrated, the shape stays crisp and readable in a working warehouse, and because nothing touches the floor, there is nothing for wheels to scuff or cleaners to lift. Mounted overhead, a line marks a permanent zone. Mounted on a vehicle, the shape travels with it and warns people on foot before the vehicle reaches them.

Where each one fits: forklifts, AGVs and pedestrian crossings

• Forklift laser warning lights: a moving boundary around the truck so pickers keep their distance — see the Forklift Safety Zone System (turns red and speaks when a person steps in) and the Forklift Boundary Light Kit (always-on LED lines).
• AGV and AMR lasers: an arrow or block arrow ahead of a driverless vehicle shows which way it is about to go; a circle marks the space it needs.
• Pedestrian safety lights at crossings and walkways: a fixed line from the ceiling marks where people cross a vehicle aisle — the Laser Safety Line Projector runs lines up to 4× its mounting height.
• Dock doors and staging lanes: a stop line or lane edge at each door; pair it with a radar or camera sensor so it lights only when a truck or person is there.
• Bumper zones: an arch in front of a reach truck or tow tractor marks the stay-clear area at the working end.
• Scissor lifts and job sites: a SafeGuide line around the base keeps people out from under a raised platform.

How to choose a laser line projector: shape, color and line length

• Line — for edges, lanes and boundaries. The SafeGuide Adjustable changes length on site with a twist ring (up to about 2× the mounting height); the SafeGuide Fixed keeps one factory-set length for less. For long aisles from a ceiling, the Laser Safety Line Projector (10–40 W) reaches further.
• Arrow — for direction of travel on AGVs, AMRs and small forklifts.
• Circle — for a keep-out ring around a vehicle or a fixed hazard. About 95 cm across at 1 m mounting height, 2.2 m at 2 m, 3.2 m at 3 m.
• Arch — for a curved bumper zone in front of a vehicle.
• Color: red reads as stop or danger, green as a safe path, blue stands apart from existing floor paint. Green looks brightest to the eye. On most units the color is set at the factory and cannot be changed later, so decide before ordering.
• Brightness: a laser is brightest when the line is narrow. On a bright floor, keep the line thin and the mounting height reasonable; for very high ceilings, choose a higher-wattage Laser Safety Line.

Mounting and power: forklifts, AGVs, walls and ceilings

Vehicle-mounted units wire straight to the vehicle’s battery. The SafeGuide lines and the circle and arch lights run on DC 10–80 V, so they suit 12 to 80 V trucks; the arrow and block arrow run on 12 or 24 V DC only. Each product page lists its exact range. On a ceiling, column or wall, those units need a plug-in DC power supply — add it as an option on the product page. The Laser Safety Line Projector plugs straight into a standard outlet (110–240 V) and is built for fixed mounting.

Each unit mounts on its own bracket, shown on its product page, and tilts to aim. Measure the mounting height first: it decides how big the line or shape will be on the floor, and each product page has a size chart.
