<p>#CMT# #/CMT# The vehicle has a hydrocuring unit (10) comprising a mechanical power transmission chain (52) transmitting power from a driving engine (14) e.g. electrical engine, to a high pressure pump (12). A transmission chain (54) transmits power from the engine to wheels (56). The chains are independent from each other. The engine rotates a shaft (60) at its end (61) to which a pulley (62) is fixed, where the pulley is made of titanium alloy. #CMT#USE : #/CMT# Cleaning vehicle e.g. small sized commercial motor vehicle, smart type vehicle, self-propelled trailer, for cleaning and stripping a surface, and for removing and cleaning a material from a duct e.g. water drain duct, in case of duct blockage in a hygienic building of an urban environment. #CMT#ADVANTAGE : #/CMT# The transmission chains transmit the mechanical power from the driving engine to respective high pressure pump and wheels, so that weight and encumbrance of the hydrocuring unit is reduced and hence weight of the vehicle is reduced. The vehicle has small dimension, so that it can be easily parked in a limited place such as place between two motor vehicles parked in a road and in a narrow parking space. The driving motor facilitates movement of the vehicle. The cleaning vehicle can be installed in intervention places such as urban environment, in an easy and rapid manner. The pulley is made of titanium alloy, thus providing a better compromise between weight, encumbrance and mechanical resistance of the vehicle. The transmission chains are independent to each other, so that defect of one chain does not affect operation of the other chain. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a schematic view of a vehicle. 10 : Hydrocuring unit 12 : High pressure pump 14 : Driving engine 52, 54 : Mechanical power transmission chains 56 : Wheels 60 : Shaft 61 : End 62 : Pulley #CMT#METALLURGY : #/CMT# The pulley is made of titanium alloy.</p> |
