These units can be angled to the right or left and can be towed behind any suitable site vehicle e.g. Land Rover, tractor, dumper or truck. The two way sweep system enables the brush to be angled from one side to the other in seconds by releasing a locating pin. The brush automatically adjusts for road camber, undulations and wear. These units have a front pneumatic castor wheel and a rigid drawbar which enables you to reverse with the sweeper attached. These are available as wheel driven units (CMA), mechanically driven units from an auxiliary diesel engine (FMB-M) or hydraulically drive units from an auxiliary diesel engine (FMB-H).
