Wet-type road sweeper（LNG）
Inheriting the comprehensive performance and reliability of last generation wet road sweeper, Zoomlion series Wet-type road sweeper is improved in many structures and is added with multiple humanized structural designs to realize more reasonable structure, more prominent performance, more beautiful shape, and more operation convenience, with the comprehensive performance leading the domestic products of same class. With multiple patents including “Sweeping device for road sweeper” and “Suction nozzle for road sweeper”, Zoomlion series wet road sweeper can be installed with additional devices, including magnet and self-cleaning flushing water pump, and is mainly applicable for the sweeping and sanitation operations for the urban roads, squares, airports, and ports.
●The liner of the waste tank adopts single-layer structure with smooth stainless steel inner walls and high strength framework to eliminate the waste absorption on inner walls during operations. The cleaning of the waste tank can be completed within 10min, featuring high cleaning convenience.
●The front sweeping device incorporates the anti-collision avoidance function (National patent) to guard the sweeping device against damage during operations.
●The full-floating suction nozzle can level automatically (National patent) based on the road condition, featuring powerful sweeping capability and fast sweeping speed.
● The chassis is installed with hydraulic power steering device to remarkably improve the driving comfort.
● The drive parts, hydraulic parts, and electric parts adopt high quality imported products.
1、The drive parts, hydraulic parts, and electric parts adopt high quality imported products.
2、The injection molded blade type sweeping brushes are applied to realize high wear resistance, powerful sweeping, and rapid replacement.
3、The full-floating suction nozzles can level automatically depending on the ground condition.
4、The front sweeping device incorporates the anti-collision avoidance function to guard the sweeping device against damage during operations.
5、The centrifugal automatic clutch coupling is applied between the auxiliary engine and fan to guarantee the automatic disengagement from the fan at the start and stop of the auxiliary engine.
● Fan noise-reduction technology: The fan vanes are optimized and the low-noise fan is designed by simulation analysis. The special spectral characteristic for the aerodynamic noise of the fan is applied and the special fan muffler is installed to reduce the working noise of the vehicle by 1~2dB.
● Power matching technology: The matching between engine speed and working condition is optimized to run the engine constantly within the economic fuel consumption zone and improve the fuel economy.
● Super-high-simulated suction nozzle technology: CFD optimized structure: The internal airflow field and the structural design of the suction nozzles are optimized by simulation analysis to improve the suction/collection capability by 10%. The unique jaw plate control structure: It ensure that the wastes of large volume can be thoroughly swept to improve the overall cleanliness.
● Pipeline firmness technology: The hydraulic pipelines adopt the world’s advanced ferrule type high-precision drawn tubes with hard mechanical seals to remarkably reduce the malfunction rate of hydraulic system.
● CAN bus intelligent control technology: The one-button control, the real-time display of vehicle working condition, working parameters, and malfunction information on display screen, and the video functions (such as monitoring function) are realized to understand the working situation at a glance and ease the driver’s operations and maintenances.
● GPS real-time monitoring technology: The information sharing between working site and the management center can be realized by information connectivity with management platform to enable the management center to real-time master the working status of the vehicle.
● Sweeping mechanism adaptive technology: The sweeping technology can automatically adjust the ground clearance of the sweeping disc based on the wear status of sweeping brush and the road condition to further improve the working cleanliness and effectively prolong the life of sweeping brush by >15%. The sweeping mechanism can automatically steer away from the obstacles on the working road and afterwards can automatically restore to normal working status, featuring high damage resistance and higher reliability.
● The Zoomlion’s pioneering “four middle sweeping discs/brushes - rear suction nozzle” symmetric structural arrangement mode eases the sweeping for both left and right road curbs.
● The centrifugal automatic clutch coupling is applied between the auxiliary engine and fan to guarantee the automatic disengagement from the fan at the start and stop of the auxiliary engine, which can improve the working reliability and life of auxiliary engine and simplify the operations.
● The waste tank is internally installed with plastic clean water tank and sewage tank of high capacity. The dust-suppression mode of clean water curtain spray is applied to save the water resource and remarkably prolong the dust-suppression working time.
● The pneumatic conveyance system adopts the lower air exhaust mode to reduce the secondary contamination.
● The manual pump emergency system is provided so that the waste tank can be retracted, lowered, and lifted with the auxiliary engine stopped, featuring convenient maintenances.
● The injection molded blade type sweeping brushes are applied to realize high wear resistance, powerful sweeping, and rapid replacement.
● The hydraulic pipelines are arranged neatly and beautifully to ease the maintenances.
● Some models are installed with high pressure water pipeline system, waste tank self-cleaning system, high pressure reel and hand-held spray gun, featuring higher operating convenience and richer functions.
