Description
Bolt two vibratory heads onto the Wyco Magflo 16 Double Power Bar when striking off massive continuous warehouse floors. This sixteen-foot magnesium extrusion eliminates dip across wide commercial placements by distributing eccentric drive force between twin clamp saddles. Dual heads increase fuel and service requirements, making this setup inefficient for small patchwork or cut-up slabs.
Extruded structural magnesium keeps overall bare bar weight at 24 lbs across its 192-inch length. The proprietary cross-section measures 5 inches across the bottom runner and 4 inches high. High-tensile magnesium repels wet concrete grout while damping transverse whip under dual eccentric loads. Dual mounting stations feature reinforced clamp pads positioned at engineered nodal points, which preserves straight profile geometry when dragging dense low-slump stone aggregates across expansive commercial bays.
Key Features of Wyco WS621440
Slab contractors who buy Wyco WS621440 components secure advantageous commercial screed bar pricing while cutting pass count on massive floor installations.
- Dual power head mounting stations distribute high-frequency vibration across sixteen feet to eliminate center harmonic dead spots
- Magnesium alloy construction sheds wet cement paste while resisting fatigue cracks from twin eccentric rotating exciters
- Curved leading edge shears excess gravel aggregate to maintain strict grade elevation ahead of the screed body
- Wide trailing float shoe seals green concrete paste prior to hand floating or mechanical troweling operations
- Extruded internal ribbing prevents lateral twist when dragging stiff zero-slump mix through thick structural sections
- Reinforced saddle clamps bite onto drive units without requiring custom mounting bolt modifications on the jobsite
- Lightweight structural profile limits physical drag resistance to lower operator muscle fatigue during marathon pours
Dual Drive Bench Vibration Analysis
Bench testing under twin vibratory units operating at 8,500 VPM demonstrates less than 0.035 inches of vertical deflection across the 192-inch span. Dual-excitation nodal positioning limits amplitude loss at the blade ends to under 4 percent from center readings. Dynamic load tests with 120 lbs of drag resistance show zero profile distortion. In 3-inch slump floor placements, the bar floated level without skipping, driving coarse aggregate below the surface while lifting paste for immediate broom or trowel finishing.
Field Usability Realities
Two operators must coordinate pull pace on this 16-foot rig to prevent skewed edges on wide bays. Handle control remains stable under full throttle. Do not buy this double-unit screed bar for narrow residential driveways, footing trenches, or spaces packed with vertical conduit stubs.
- Rinse wet concrete from clamp tracks with water before paste takes final set
- Torque dual power unit mounting clamp bolts before every pour to stop vibration wallow
- Check the bottom runner with a string line every month to monitor straightness
Wyco Factory Warranty Details
Wyco provides a 1-Year limited manufacturer warranty covering material flaws and structural extrusion defects. The factory shipment contains the bare 16-foot dual-mount Magflo screed bar, twin power unit mounting clamp kits, protective plastic end caps, and an illustrated technical instruction sheet for rapid field setup.
