Wyco 2-3/8in Polyurethane Coated Square Vibrator Head

Description

Bridge construction crews struggle to reach deep pier caissons when standard vibrator shafts stop ten feet short of grade. The DEWALT Deep Form Concrete Vibrator Shaft reaches forty feet into vertical forms to consolidate structural concrete. Its massive 40-foot casing creates heavy drag, requiring two workers to haul the head upward between placement lifts.

Hardened steel alloy forms the 2.25-inch diameter vibrator head casing, heat-treated to resist abrasive stone friction in low-slump mix. The flexible drive shaft spans 480 inches, encased within an oil-resistant rubberized outer casing armored with internal spiral carbon steel ribbon. Bare tool weight registers at 42 lbs. A machined quick-disconnect coupling engages DEWALT POWERSHIFT power heads in seconds without wrenches or threaded collars on site.

Key Features of DEWALT DCPS35912

Infrastructure contractors who buy DEWALT DCPS35912 assemblies secure competitive commercial concrete vibrator pricing while reaching extreme structural zones that stall shorter vibrator shafts.

• Massive forty-foot shaft length consolidates deep bridge piers, retaining walls, and tall caissons
• Two and one-quarter inch hardened steel head delivers broad consolidation radius in stiff concrete
• Spiral steel armored casing protects internal drive core against crushing and sharp aggregate abrasion
• Quick-connect coupler locks straight into DEWALT POWERSHIFT battery power heads in seconds
• Double-sealed bearing design inside the head blocks caustic grout intrusion and retains internal lubricant
• High-tensile inner core cable transfers rotational energy with minimal torsional 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 40-foot shaft verifies that rotational core torque transfers efficiently, holding 10,200 VPM at the head with under 6.0 degrees of angular core twist under load. The 2.25-inch head delivers over 850 lbs of centrifugal compaction force inside dense mix. In deep pier tests using 3-inch slump structural mix, the head eliminated internal voids thirty-eight feet down, maintaining steady consolidation action without motor bog, shaft kinking, or excessive outer casing heat buildup.

Field Usability Realities

At 42 lbs, managing this 40-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 40-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 40-foot shaft in wide four-foot loops for transport to prevent permanent core bends

DEWALT Factory Warranty Manifest
