Adjustable Barrier Handling System
The ALG series is designed to provide secure gripping and safer lifting for a wide range of barrier sizes. The infinitely adjustable configuration allows operators to quickly adapt the grab for different concrete barrier widths while maintaining proper load engagement.
The integrated locating assembly helps automatically orient the grab during lifting operations, reducing the need for manual adjustment and improving operator efficiency.

Replaceable Gripping Pads
Standard polyurethane gripping pads help protect concrete surfaces from chipping, scratching, and cosmetic damage during lifting operations.
Optional hardened alloy steel “Dog Point” pads are available for painted or coated barriers where additional grip is required. These pads are commonly used in coastal regions and infrastructure applications where barriers are painted for corrosion resistance or identification.

Improved Operator Safety
Extended operator handles help keep workers away from suspended loads during positioning and removal. Adjustable handle positioning allows the grab to be configured for different lifting conditions and barrier sizes.
Color-coded travel decals and position indicators simplify adjustment setup and help ensure proper grab engagement before lifting.

Durable Construction for High-Cycle Use
The Caldwell ALG Adjustable Lifting Grab is engineered for rugged, repetitive lifting operations in demanding jobsite conditions. Heavy-duty steel construction and industrial-grade components help provide long service life in highway construction, bridge work, utility projects, and precast operations.
