In pumped concrete mixes, available/bleed water can be an issue. The faster the vibrator speed, the more water separation occurs and collects on the form faces. Chipping and patching labour and patch material can be expensive. Minnich M-Box operators can select from speeds of 6,000, 8,000, and 10,800vpm. The product converts the 230V, single-phase outlet of a 3,500W generator to 230V, three-phase output, allowing the operator to choose a uniform and compatible constant speed under different concrete loads.
The firm claims that the unit allows customers to control the quality of their concrete more precisely. The company says that by helping operators apply the most force with the lowest speed, the M-Box maximises vibration quality and, in turn, the quality of the concrete structure.
Accurate vibration control from Minnich
Minnich Manufacturing has developed its M-Box vibration control solution, an innovative control speed high-cycle power converter. This unit enables high-cycle vibrator operators to control the speed/vibrations per minute (VPM) of up to two vibrators. According to the firm, the M-Box minimises time and cost associated with patching structural concrete surface blemishes caused by excessive vibrator speeds.
