The EXEN Dam-Use High-Frequency Vibrator (Model HIB100A) is a specialized solution designed for efficient concrete compaction in confined or hard-to-access areas such as dam construction zones and sand control dams where large machinery like hydraulic shovels cannot operate. Operating at a high frequency of 120–125 Hz, and delivering powerful centrifugal force up to 9.56 kN, this vibrator ensures reliable performance for placing low-slump, coarse-aggregate dam concrete.

Built on EXEN’s proven track record in dam work equipment, the HIB100A features a durable, high-performance motor and a uniquely shaped, abrasion-resistant tip made from thermally treated ductile cast iron—ideal for withstanding harsh conditions and contact with rocky surfaces. The replaceable tip design extends the product’s lifespan and reduces maintenance costs.

Its compact form and ergonomic handle include a rubber damper to minimize hand-arm vibration, allowing operators to work longer with less fatigue. A new lightweight round plug improves operability and compatibility with EXEN’s dam inverter systems and distribution boards, simplifying setup and reducing maintenance hassle.

Whether used in small sand control structures or large-scale dam applications, the HIB100A offers dependable, high-performance concrete vibration where precision, power, and maneuverability are essential. It’s a go-to solution for contractors working in rugged, space-restricted concrete placement scenarios.
