Weigh In Motion 28/05/12 – 01/06/12
WEIGH IN MOTION OVERVIEW • Weighing in Motion (WIM) devices are designed to capture and record axle weights and gross vehicle weights as vehicles drive over a measurement site. Unlike static scales, WIM systems are capable of measuring at either a reduced or normal traffic speed, and do not require the vehicle to stop • The WIM area consists of 3 lanes. 2 standard and 1 OOG / B Double lane
WEIGH IN MOTION PROCESS • Trucks to enter the Weigh In Motion via the main roadway between 4 and 5 berth • All trucks carrying a load will be required to enter the WIM (including MT containers) • Trucks to proceed to pinning area behind grid 6, and pin containers (PPE to be worn at all times) • Enter the WIM (booms remain upright unless a truck is in the WIM) • Truck to proceed at constant speed (under 5kms) to the kiosk • Axle group weights will be visible on the LED scrolling screen display, followed by total weight and a light status – Green / Orange / Red • No breach – Green Light • Minor – 0 to +5% - Orange Light • Substantial - >5 to + 20% - Orange Light • Severe - >20% - Red Light
ACCURATE WEIGHT READING • Trucks must travel at a constant speed, under 5 km’s per hour (recommended Crawler Gear) • Truck axles must stay over the WIM pads at all times • No braking whilst in the WIM airlock area, until clear of the weigh pads
GREEN STATUS DRIVER RECEIVES A GREEN LIGHT – NO WEIGHT BREACH Driver approached kiosk • Swipe MSIC • Enter Bat Number • Receives ticket with completed container details • Exits WIM to Physical Security Check
ORANGE STATUS DRIVER RECEIVES ORANGE LIGHT Minor – 0 to +5% Substantial - >5 to +20% Driver approached kiosk • Swipes MSIC • Enter Bat Number • Receives ticket with completed container details • Exits WIM to Physical Security Check NOTE; Trucks are required by law to proceed directly to a container freight station for repack / reposition
RED STATUS RED LIGHT IS VISIBLE AS AXLE GROUP IS ‘SEVERE OVERWEIGHT CATEGORY’ Driver approached kiosk • Swipe MSIC • Enter Bat Number • Driver is asked if they have CML or HML certificate • Select ‘No’ • Truck configuration and container numbers are displayed • Driver selects X for containers he wishes to leave on his truck • Confirms removal of container • Ticket received with container details / Yard position • Driver MUST enter the truck park to undo pins • Proceed to Light at Truck Park • Once instructed by Road Controller, driver proceeds to Yard Position for unload • Driver must then re-enter the WIM until a Green / Orange light is received
RED STATUS – CML / HML Certified CML CERTIFICATE – CONCESSIONAL MASS LIMIT HML CERTIFICATE – HIGHER MASS LIMIT • Red light is visible as axle group is ‘severe overweight category’ Driver approached kiosk • Swipe MSIC • Enter Bat Number • Driver is asked if they have CML or HML certificate • Select ‘YES’ • Overload weights are displayed on screen • Driver determines if these weights meets his certificate approved weights • Receives ticket with completed container details • Exits WIM to Physical Security Check
Over Speed / Bad Read • The speed limit of the Weigh In Motion area is under 5km/hr (suggested crawler gear) • Over speed is obtained by travelling over 5km/h • Bad read is obtained by not travelling at a constant speed i.e stop / starting over the weigh pads • Drivers who receive a To Fast / Bad Read status will be required to exit the WIM area, proceed down the main roadway between Grids 4 & 5, turn right along grid 5 and back along grid 6 to re-enter the WIM area • Following this traffic flow procedure and re-waiting in the WIM queue can be time consuming for the driver. We suggest you ensure your drivers are aware of the consequences to not following the instructions to ensure a correct read
