Maintaining the cleanliness and presentation of urban and residential streetscapes has long been a critical task for local governments in Australia. Councils have traditionally relied heavily on diesel powered street sweepers to keep their public spaces clean and improve the safety of paved areas, footpaths, gutters and bike lanes.
These machines use hydraulic fluid under pressure to power components such as the brooms and drive transmissions, suction turbines and their hoppers. It works well when it works well – but does come with its share of issues.
Hydraulic fluid spills and leaks, the environmental impacts, higher maintenance costs and injury risks are some of the issues that have plagued city cleansing and maintenance crews for decades.
The hydraulic system of a street sweeper comprises a complex network of pipes and pumps that distribute hydraulic oil throughout the machine. If any of these components leak or break, the pressurised oil can escape, spreading far and wide, which is a disaster during street cleaning.
With an electric sweeper that has been designed and built from the outset as electric, little-to-no hydraulics operate while the machine is in operation. Hydraulics may be engaged for certain functions, such as dumping the hopper contents into a waste receptacle. However, keeping hydraulics to a minimum, keeps risk to a minimum, too.
Further to significantly reducing the risk of hydraulic fluid leaks, electric sweepers offer a number of key advantages.
Electric sweepers, designed and built from the ground up as electric machines, offer plenty of advantages for councils. While hydraulic equipment has been the backbone of street sweeping for years, the trend is globally shifting towards electric street sweepers, like the efficient EcoSweep 2000.
The City of Westminster is a leading example of this shift to electric city maintenance, in a bid to improve air quality in the high-density Central London area.
The Council is on target to achieve their goal of a complete green fleet transition by 2030.
An electric street sweeper is more efficient because it has a direct connection between the power source and the motor, translating to just 10% loss of power. However, a diesel sweeper goes through a much less efficient process of burning fuel to generate electricity, which results in energy loss. This means an electric sweeper can do the same job with less energy, making it more efficient.
For a clearer illustration, refer to the following image which compares the loss of energy in hydraulic powered machines and electric powered machines. Using a 100% electric powered machine means less energy lost and more mechanical energy available for use, translating to more efficient operation.
For many communities, clean and tidy streets are a point of pride. But city cleansing and presentation is more than a point of pride; it’s also a requirement of compliance with relevant safety and environmental regulations.
For councils, clean and tidy streets offer benefits to residents, local businesses and the environment.
