Compact precast form vibrator

Industrial vibration technology pioneer has introduced a heavy-duty compact electric vibrator engineered for the inside or outside of small diameter precast concrete pipe form cores. The Martin MB36-3000 Concrete Form Vibrator offers what engineers call excellent compaction of the cast for improved material strength. The rugged design has a high force-to-weight ratio and ensures reliability using high heat-rated internal components, allowing the unit to perform consistently under punishing conditions for extended periods.

“These units solve problems common to the precast industry by delivering as much power on the inside of the smaller diameter core as on the outside,” says Martin Engineering Distributor Manager Larry Horrie. “By providing consistent consolidation, the vibrator helps operators produce stronger casts with fewer bug holes or voids.”

The competitively priced MB36-3000 is engineered to be one of the most durable units on the market and carries a three-year warranty, he adds, noting, “Our customers were requesting this specific type of model for their precast pipe forms, and this design is the result of meticulous research, engineering and testing. The efficient, compact design and performance guarantee reflects our commitment to superior construction and a lower life-cycle cost. It also allows our customers to standardize on one unit for a wide range of applications.”

At 14.4-in. wide, the compact design eases MB36-3600 installation in tight spaces. Suited to most standard mounting configurations, the 230/460 volt, 3 Phase, 60-Hz motor runs at 3,450 rpm, allowing the vibrator to supply a centrifugal force output of 3,000 lbf using permanently lubricated roller bearings in ductile iron flanges. Adjustable eccentric weights enable operators to customize force, save energy and maximize vibrator service life.

To mitigate material accumulation, dust and moisture penetration commonly found in precast applications, the resilient aluminum casing has a smooth gloss coating and covers sealed by O-rings. Internal high temperature Class H windings are able to withstand continual use in a heated, sealed environment, further ensuring reliability. — Martin Engineering Co., 800/544-2947; www.martin-eng.com
