Hoist's all-new AC motor

The first AC-powered Lazer has rolled off Hoist Liftruck's East Chicago, Indiana assembly lines.

Lazer models are available in capacities ranging from 15,000 to 40,000 lbs (7-18 T). Historically only offered as DC-powered, the new line gives customers another option.

AC-powered forklifts were initially more widely available in Europe, but only in smaller-capacity models. With the AC Lazer, Hoist claims to be one of the first manufacturers worldwide to offer AC power in high-capacity electric trucks. The Lazer E400, with a 40,000 lb. [18,144 kg] capacity, is at the top of the scale.

The AC Lazer offers Hoist customers reduced maintenance costs and increased efficiency. The AC motors eliminate the parts and labour costs associated with changing brushes, as required with DC motors. Additionally, AC motors generate less heat as it can dissipate directly from the motor enclosure during operation, while DC motors produce heat internally, reducing performance and longevity. AC drive systems require fewer components as directional contactors are no longer required, further reducing maintenance and replacement part costs.

Hoist claims AC motors can also be more finely tuned and have the ability to handle higher peak currents than their DC counterparts, leading to greater reliability, higher life expectancy and better performance.
