When performing physical labour with heavy materials an ergonomically justified working height is of utmost importance.To position Deltaracks at the optimal work height for manual loading and unloading, you can simply stack europallets (with the same base dimensions as the A1 and B1 models) on the universal cart. Unlike some conventional glass and stone racks, all models can be picked up by a fork-lift truck, making it easy to raise them to any desired height.
