Description

Multiquip FS21 21-Foot Flexible Concrete Vibrator Shaft

The Multiquip FS21 21-Foot Flexible Concrete Vibrator Shaft is a heavy-duty power transmission assembly engineered to transfer high-torque rotational energy from drive motors to vibrating steel heads. Constructed with a high-carbon spring wire inner core and an armored steel-mesh rubber casing, this 21-foot flexible shaft enables concrete contractors to consolidate deep wall forms, tall columns, and foundation footings without shifting motor placement.

Best Used For:

  • Deep Wall and Column Consolidation: Reaching into tall concrete wall forms and vertical column pours up to 21 feet deep to eliminate air pockets and honeycomb defects.
  • Foundation and Slab Pours: Extending reach across large-footprint structural concrete slabs without relocating the primary drive motor unit.
  • High-Torque Head Driving: Transmitting continuous rotational torque reliably to heavy-duty steel vibrator heads ranging from 1-3/8 inches to 2-5/8 inches in diameter.

Key Performance & Safety Features

  • High-Carbon Spring Wire Core: Precision-wound inner core resists stretching, unraveling, and binding under high rotational torque loads.
  • Armored Reinforced Casing: Multi-layer rubber jacket containing flat steel wire and steel wire mesh prevents kinking, crushing, and severe outer abrasion.
  • Quick Disconnect Coupler: Integrated quick-coupler mechanism permits tool-free connection to compatible drive motors for fast job site setup.
  • Contamination-Proof End Seals: Dual internal seals retain core grease lubrication and block wet cement paste from entering the drive mechanism.
