SICK has developed a customisable, active collision warning system for manned forklifts, the SICK Backup Assistance System (BAS), which alerts drivers to prevent collisions with people or objects, where their view is restricted for example by blind spots or during reversing.
With some 1,300 UK employees hospitalised each year with serious injuries following forklift accidents, key contributing factors can be lapses in driver concentration, or increased speed and movement due to high productivity targets.
The SICK BAS is based on robust and reliable SICK LiDAR sensing technology that can be added easily to most forklift types for minimal investment. Unlike other active technologies, with the SICK BAS there is no need to attach expensive additional equipment to surrounding obstacles. Operators in factory and logistics environment therefore have a new opportunity to reduce the risk of forklift accidents cost-effectively.
“Forklifts are widely recognised to pose one of the greatest workplace safety concerns to pedestrians, with some of the highest risks of serious injury,” explains Neil Sandhu, SICK’s UK National Systems Product Manager. “Unlike when driving a car, a forklift operator might reverse for several hours during the day, so needs to stay particularly alert to potential collisions.
“However, many forklift collision warning systems are passive, which means they use constant audible alarms, warning lights or distracting in-cab driver camera displays. Although some active warning concepts, such as radar, have previously been available, the SICK BAS is an affordable, stand-alone system that does not require the installation of reflectors or transmitters all around production and logistics halls, and staff don’t need to wear special pads or tags.”
The SICK Backup Assistance System uses a novel concept based on the SICK TiM351 LiDAR sensor to alert only when a stationary or moving object or person is detected. Comprising a SICK Tim351 LiDAR sensor, control unit, and signal light bar with audible alarm, the SICK BAS is quick to install and has a low power demand to minimise drain of the vehicle’s battery. A weather protection hood is available, as well as mounting accessories including shock absorption brackets to help with increased vibration that may be seen.
Either one or two SICK Tim351 LiDAR sensors can be mounted on the forklift to provide coverage of the required areas, and can also be mounted to give visibility to the side of the vehicle. The monitored area is scalable and can be adjusted with the help of flexible mounting options on the vehicle. The SICK BAS is therefore well suited to ensure target coverage of known blind spots, and also optimises coverage of the area to the sides of the forklift where the drivers view may be restricted.
