Other Products ｜Caldwell BLG Barrier Grab for Concrete Barriers

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.

Key Features

Replaceable polyurethane pads to protect concrete surfaces
Optional alloy steel “dog point” pads for painted/coated barriers
Centering guide cut-out helps position grab correctly over barrier
Extended operator handles keep workers clear of suspended loads
Adjustable handle positions depending on application
Self-centering lifting eye for balanced rigging
Fork truck compatible handling design
Built for repetitive high-cycle construction use
Designed to ASME B30.20 and BTH-1, Service Class 3 standards

Applications

Highway barrier installation and removal

Design & Operating System
The BLG uses an automatic engagement system that allows the grab to lock onto the barrier when the crane line is properly slackened. Once engaged, lifting force secures the grip, and the locating assembly helps ensure the tong aligns correctly without manual adjustment.
This design reduces the need for workers to position themselves near the load, which is a major safety improvement in highway and roadside operations.

Safety & Construction Benefits

Reduces manual handling during barrier placement
Improves operator distance from suspended loads
Helps prevent surface damage to concrete barriers
Speeds up repetitive lifting cycles
Provides consistent grip alignment across varying barrier conditions
Suitable for demanding DOT jobsite environments

Standards & Compliance

ASME B30.20 (Below-the-hook lifting devices)
ASME BTH-1 (Design of below-the-hook lifting devices)
Service Class 3 (high-cycle industrial use rating)
