Swiss company Haenni Instruments is highlighting the WL 108 XL portable wheel load scale. Its active surface of 1395 x 393 mm is big enough to accommodate the wheels of vehicles of any size, with any axle configuration. Despite its huge weighing area, the device weighs only 28.5 kg and is equipped with rechargeable batteries that power it for at least 120 hours before it needs to be recharged.
