DEWALT 1-1/2 Inch Vibrator Head with 40 Ft Shaft

Description

Reach the base of forty-foot civil bridge caissons using the DEWALT Deep Form Concrete Vibrator Shaft on structural infrastructure pours. Its 1.5-inch diameter hardened steel head navigates congested rebar grids where larger vibrators hang up. The massive 40-foot length creates significant extraction friction, requiring two workers to pull the assembly upward between concrete lifts.

Hardened steel alloy forms the 1.5-inch diameter vibrator head casing, heat-treated to resist abrasive stone friction in low-slump mix. The flexible drive shaft spans an incredible 480 inches, encased within an oil-resistant rubberized outer casing armored with internal spiral carbon steel ribbon. Bare tool weight registers at 39.5 lbs. A machined quick-disconnect coupling engages DEWALT POWERSHIFT power heads in seconds without wrenches or threaded collars on site.

Key Features of DEWALT DCPS33812

Infrastructure contractors who buy DEWALT DCPS33812 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, dam footings, and tall commercial caissons
• One and one-half inch hardened steel head maneuvers through congested rebar cages and narrow forms
• 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 rotational core torque transfers efficiently, holding 10,200 VPM at the head with under 6.0 degrees of angular core twist under load. The 1.5-inch head delivers over 520 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 39.5 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
