These systems consist of different plates, each with four threaded inserts for safe lifting. Two short and two long safety bolts secure the test plates when they are lifted. A traverse with two safety anchor points distributes the lifting force via a 2- or 4-strand chain to the crane hook. The test plates are connected to the bolts and the traverse via two square tubes. The test plates are simply placed on top of each other with a forklift/crane. Cones that are integrated into the plates are centred on each other. All metal parts are primed and painted in traffic red (RAL 3020), and all concrete slabs are painted in light grey (RAL 7035). The weights have a tolerance of -0 / + 2.5% and are poured with a scale. The weights cannot be calibrated.
