DEWALT 2-1/2 Inch Vibrator Head with 32 Ft Shaft

Description

Rotational core torque spins an eccentric exciter to consolidate deep concrete when the DEWALT Concrete Vibrator Head Shaft drops into tall structural forms. Spanning thirty-two feet, this 2.5-inch hardened steel head clears internal air voids in bridge piers and dam foundations. The massive 32-foot casing requires deliberate two-worker handling when hauling upward between lifts.

Hardened steel alloy forms the 2.5-inch diameter vibrator head casing, heat-treated to resist abrasive stone friction in low-slump mix. The flexible drive shaft spans 384 inches, encased within an oil-resistant rubberized outer casing armored with internal spiral carbon steel ribbon. Bare tool weight registers at 38.5 lbs. A machined quick-disconnect coupling engages DEWALT POWERSHIFT power heads in seconds without wrenches or threaded collars on site.

Key Features of DEWALT DCPS3659

Infrastructure contractors who buy DEWALT DCPS3659 assemblies secure competitive commercial concrete vibrator pricing while reaching deep structural zones that stall shorter vibrator shafts.

• Massive thirty-two foot shaft length consolidates deep bridge piers, retaining walls, and tall caissons
• Oversized two and one-half inch hardened steel head delivers massive consolidation radius in stiff concrete
• Spiral steel armored casing protects the inner flexible core against severe aggregate friction and crushing
• Quick-connect coupler connects straight to DEWALT POWERSHIFT power heads without wrenches
• Precision double-sealed bearings inside the head protect against high heat and cement slurry ingress
• High-tensile inner core cable transfers rotational torque with minimal rotational whip over long spans
• Hardened steel casing withstands severe aggregate abrasion and high impact against formwork

Long Shaft Bench Torsion Testing

Bench dynamometer analysis on this 32-foot shaft verifies that rotational core torque transfers efficiently, holding 10,200 VPM at the head with under 5.5 degrees of angular core twist under load. The 2.5-inch head delivers over 1,150 lbs of centrifugal compaction force inside dense mix. In deep pier tests using 3-inch slump structural mix, the head eliminated internal voids thirty feet down, maintaining steady consolidation action without motor bog, shaft kinking, or excessive outer casing heat buildup.

Field Usability Realities

At 38.5 lbs, managing this 32-foot shaft requires two workers to guide the head into deep forms and haul it upward between lifts. The quick-connect locks solid with mud on the collar. Do not buy this massive 32-foot shaft assembly for shallow sidewalk slabs, residential footings, or short deck pours.

• Rinse wet concrete paste from the steel head and casing with fresh water after each pour
• Inspect the quick-connect spline drive for stone grit before clicking into the power head
• Coil the 32-foot shaft in wide three-foot loops for transport to prevent permanent core bends

DEWALT Factory Warranty Manifest
