The safety feature also includes an overload voltage protection device. The machine is also equipped with an integrated water spraying system which prevents dust from blowing in the air when the side brush comes in contact with the dust. This feature makes the sweeping productivity very effective in a dusty tropical country like India where dust is a major concern for cleaning. In other machines without the water spraying system, the dust escapes in the air and settles back on the ground thereby making the sweeping less efficient. The PB-155 is made of welded steel frame for solidity and durability. Reverse alarms are another safety feature of the machine making it very safe for the operator and the people around. Control panel is extremely easy and self-explanatory. The PB-155 is an ideal machine for use in factories, cement plants, power plants, industrial complexes, large housing societies, railway stations, airports, parking lots, bus stations, etc.
