Concrete elements used to separate lanes of traffic at roadworks often weigh 2.5t or more, and can be difficult to move. A new mechanical lifting device from Scanlift allows any concrete blocks to be laid and collected by one person without needing straps or chains. No hydraulic or electric power supply is needed as the grab has a purely mechanical scissor action and a patented locking mechanism. The model 2003 has a safe working load of 2,800kg.
