<p>The present invention relates to a spreader for road snow removal that can prevent a hydraulic working fluid from being completely lost when a hydraulic working fluid hose is damaged, prevent a geared pump connected to a spreader engine from being damaged, as well as preventing the spreader engine from being damaged due to overheating. A spreader (1000) includes a spreader engine (1100) provided with a radiator (1110) and operated by an on/off switch (1120); a geared pump (1200) for feeding a fluid; a hydraulic working fluid tank (1300) for supplying and recovering the working oil to or and from hydraulic lines (1310, 1320); a spreading unit (1400) for spreading chemical on the snow of a road; a main control box (1500) for controlling each valve so as to control each part of the spreading unit and connected to the on/off switch of the spreader engine so as to operate the spreader engine; a level detecting unit (1310) for detecting the level of the hydraulic working oil in the hydraulic working fluid tank; and an auxiliary control unit (1600) having a working oil loss warning light (1610) operated by a signal from the level detecting unit, and a hydraulic working oil detecting relay (1620) for sending a signal to the spreader engine or the main control box to turn off the on/off switch in response to the signal of the level detecting unit.</p> |
