LHF 14 Products

LHF — high-frequency compaction for continuous duty

The LHF series runs on 42 V safety voltage at 200 Hz, powered by an HFO or HFO-E converter. With no carbon brushes in the poker, maintenance stays minimal and speed stays constant — even through hours of pouring. Heads from Ø 36 to 65 mm cover everything from walls to mass foundations.

Why 42 V instead of 230 V?

Safety extra-low voltage is the safest choice around wet concrete — and the high-frequency direct drive delivers far more compaction output per kilo of machine than a 230 V motor.
