Vacuum SweeperVSM-140

One main broom (375mm dia) and two side brooms (500mm dia) — all hydraulically rotated and hydraulically raised and lowered — sweep gravel, leaves, litter, and sand into the path of the suction hose. A high-efficiency, dynamically balanced blower, driven from a split PTO, draws that debris into a hydraulically operated hopper (1.4 cum, 2mm thk MS) at the rear. Dust pulled in with the debris passes through 8 pleated filters (34 sq m filtration area) before the air is released, with an automatic pulse-jet system — 12V DC solenoid-operated pneumatic valves on a PLC-based timer — periodically clearing the filters so airflow and suction stay consistent. When the hopper is full, it's manually opened at the rear via a locking rear door for unloading. All controls, including broom up/down and rotation, hopper up/down, and PTO/blower on-off, are provided in the driver's cabin.

Mounted on a compact truck chassis, the VSM-140 is sized for narrow residential streets, parking lots, and lighter-duty municipal routes where a larger sweeper would struggle to maneuver. Its 1.4 cum hopper suits frequent, shorter runs rather than high-volume all-day routes, and because the blower draws power straight from the vehicle's own split PTO, no separate auxiliary engine needs to be carried, kept fueled, or maintained.
