All-electric sweeper15th of June 2010
The Green Machines 500ze is an all-electric vacuum street sweeper developed by Tennant. With its Lithium-ion powered battery pack, this new machine heralds a significant step in the drive for reduced carbon emissions and improved air quality, the company claims. Its clean air and near silent operation is suitable for enclosed or crowded pedestrian areas such as city centres.
The 500ze boasts zero emissions - saving the equivalent of 40 cars' carbon output every year - and is designed to be almost invisible to pedestrians. It is virtually silent in transit, says Tennant, so it can be used to clean at any time of day and near sound-sensitive environments. Power is supplied by Lithium-ion batteries, with integrated Battery Management System to optimise cell performance. This energy supply is said to be as reliable as conventional fuel and recharging the batteries provides eight-hour operation at a fraction of diesel costs.
The Cloudmaker misting system provides improved dust control while minimising water consumption - Tennant claims the 500ze uses 70 per cent less water than other traditional dust control techniques.
Speeds of up to 25 km per hour can be achieved and the ergonomic design means the operator enjoys a car-quality experience.
The Green Machines 500ze is currently in trials across Europe.
