Snow Clearance made easy

snow clearance

Freezing conditions throughout the UK have highlighted how badly prepared we are for snow and ice. Whole communities brought slithering to a halt by the cold weather. Everyone is asking “Where are our snow ploughs?”

This paragraph was written in January 2010. Sitting here with 6″ of snow outside and many schools closed and what seems like most people sitting at home watching Jeremy Kyle I am forced to think that not much has changed.

Once the snow is on the ground it’s tough if you haven’t made plans for such an eventuality. As a provider of machines that clear snow quickly and efficiently we have a vested interest. However the modern snow clearance machine doesn’t have to sit there for the other 50 weeks of the year gathering dust. Our Powerflex machines are multi-purpose, so if you buy a road sweeper you can also buy a snowplough attachment and voila, sweeper becomes snowplough in about 5 minutes. Now your sweeper, which you can’t use in the snow, becomes a snowplough which is just what you want.

This philosophy runs through the whole range of machines. Snowploughs, brushes and blowers are available – find the range here.

Sweeping Changes

Sweeper cut awayWe supply sweeping machines that use an overthrow sweeping system. So what you might say, well let me explain.

In the illustration you can see how our Brava sweeper is arranged internally. Notice the brush rotation is against the direction of travel and that the collected dirt and debris are thrown over the brush into the rear-mounted hopper. Now this has many advantages over the forward throw system used by other manufacturers.

OVERTHROW SWEEPING SYSTEM:
• The dirt is thrown from high to low, so the hopper can be deeper and have a greater capacity.
• The hopper can be filled to 80-90% of its capacity.
• Collection of light and heavy, small or bulky dirt is easy and equally effective.
• Perfect visibility of the work area because the hopper is at the rear not the front.
• A large range of size and type of dust filters can be used to improve performance in different circumstances.

FORWARD THROW SWEEPING SYSTEM:
• The dirt is thrown up from below and therefore hopper must be shallow
• The hopper can only be filled to 50-60% of its capacity as the dirt tends to collapse back onto the brush
• Collecting light and bulky debris is much less effective (leaves, paper, etc.)
• Poor visibility of the work area because the hopper is stuck out in front of the brush.
• Smaller dust filters are used so as not to penalise visibility, but that reduces the sweeper’s performance.

So there you have it – over throw sweepers are going to collect more dirt and debris in any given situation and they will work longer and more efficiently. Don’t take my word for it – try one and see for yourselves.
