WYCO 1-3/4" Polyurethane Coated Square Vibrator Head - W878-534
What our Experts Think
-
Faster, deeper consolidation with Square Head tech: The WYCO 1‑3/4″ Polyurethane Coated Square Vibrator Head – W878‑534 uses Wyco’s patented Square Head design, which has up to 27 % more surface area than a round head — helping consolidate concrete 20–50 % faster and more completely, even in low‑slump mixes.
-
Polyurethane coating protects rebar: The polyurethane coating guards against rebar abrasion and surface damage during vibration, extending head life and preserving finish quality in reinforcement‑dense pours.
-
Engineered for durability and cooler operation: Made from hardened, solid bar stock, this head resists wear and runs cooler than traditional heads, improving lifespan and reliability under frequent use.
-
Efficient vibration pattern for fewer voids: The unique square orbit pattern increases displacement efficiency, promoting better air‑void removal and denser concrete compaction.
-
Ideal for versatile jobsite use: Compatible with most standard flexible shaft and motor combinations, this head suits a range of pours — from slabs and footings to walls and columns
Q&A
Q: What is the WYCO W878‑534 vibrator head?
A: It’s a 1‑3/4″ square concrete vibrator head with a polyurethane protective coating, used for internal concrete consolidation when attached to a vibrator shaft and motor.
Q: What makes the Square Head design effective?
A: Wyco’s Square Head technology offers up to ~27 % more surface area than round heads, creating a unique orbit vibration pattern that consolidates concrete faster and more thoroughly, especially in low‑slump mixes.
Q: Why is this model coated with polyurethane?
A: The polyurethane coating helps protect the head and nearby rebar from abrasion/damage, extending service life in rugged construction environments.
Q: How does this head improve jobsite performance?
A: Compared with round heads, the Square Head design speeds concrete consolidation and reduces cavitation (air pockets), leading to a more uniform, dense finish with improved structural integrity.
Q: What are typical uses for the W878‑534 head?
A: Ideal for slabs, footings, columns, walls, and other poured concrete work where internal vibration is required to remove entrapped air and settle the mix.
Q: What are the basic specs of this head?
A: It weighs about 6 lbs and is machined from solid hardened steel with a protective polyurethane coating and compatible with Wyco vibrator shafts/motors.
Q: Who benefits most from this product?
A: Concrete contractors and construction crews seeking a durable, efficient vibration solution for improved concrete consolidation and finishing.
Maintenance Tips
-
Disconnect Power Before Handling: Always unplug or disconnect the vibrator system before inspecting or servicing the head.
-
Inspect Head & Coating: Check for cracks, tears, or excessive wear in the polyurethane coating; replace immediately if damaged.
-
Clean After Each Use: Remove concrete residue from the head and shaft to prevent buildup and maintain vibration efficiency.
-
Check Connections & Clamps: Ensure fittings, quick-connects, and couplings are secure before operation.
-
Store Properly: Keep the head in a dry, ventilated area; avoid sharp bends in attached hoses.
-
Avoid Overuse: Operate within manufacturer-recommended time and power limits to prevent overheating or coating damage.
