The Caldwell Model BLG Barrier Grab is a heavy-duty lifting attachment designed for safe handling of concrete barriers, jersey barriers, and precast highway components.
It is widely used in road construction and infrastructure work where fast, secure, and repeatable barrier placement is required.
The BLG series is built with a compact, rugged frame and engineered for controlled lifting of barriers typically ranging from 6″ to 12″ nominal top width. It uses an automatic latching system and self-centering geometry to reduce operator interaction during engagement and release, improving both safety and efficiency on the jobsite.
