Makita uses seismic knowledge in reduced-vibration power tools

Japanese power tool manufacturer, Makita, has adapted the science of earthquake engineering into power tools with its Anti-Vibration Technology (AVT).

The technology is designed to minimise vibration across a range of tools. The HR4011C hammer drill has a vibration rating of 4m/s2.

Japanese power tool manufacturer, Makita, has adapted the science of earthquake engineering into power tools with its Anti-Vibration Technology (AVT).

According to the company, AVT is an innovative counterbalance design that provides the professional with a power tool solution with reduced vibration and noise, and more efficient power.

Seismic research has developed this damping science over years to absorb shocks and protect buildings from earthquake vibrations.

AVT technology is available in a growing range of power tools, including the breaker hammer, rotary hammer, reciprocate saw and jig saw.

AVT is demonstrated in the HM1810 model - a 150kg breaker used for heavy demolition applications. The HM1810 has three times less vibration than other models, a powerful 15AMP motor, 1,100 blows per minute (BPM), 63 joules of impact energy and a reduced noise level of only 107dB.

The JR3070CT reciprocate saw, with AVT, demonstrates how much improvement in performance is available when excessive vibration is removed, according to Makita. With a vibration rating of only 8.8m/s² the saw provides the professional user with two times less vibration than other models and 45% faster cutting.

The HR4010C SDS-max rotary hammer drill also features AVT technology with a vibration of only 4.5 m/s² at 2,750BPM.

The HR4011C model produces 11AMP of power with 9.5 joules of impact energy, and has synchronised RPM and BPM to prevent overlapping impacts. A variable speed dial with five different preset speeds and electronic speed control minimises speed loss for 28% faster drilling.

Raman Sood, business development manager, Makita, said that poor vibration management could have serious health and safety implications.

"Grinders and hammers are the majority of power tools used by operators. Our grinders models GA7040S, GA9030 and GA9040S come with a low vibration rear handle, which ensures fatigue-free operation. We emphasise the benefits of AVT to the end users through our field specialists."
