Forklift in winter low temperature situation1, low temperature driving job precautions
(1) Before entering the cold, do a good job in seasonal maintenance work, and the relevant parts of the engine and chassis use cold zone lubricants, and the operation should be slowly accelerated.
(2) It is forbidden to move forward when the forklift is traveling. When the ice and snow weather is driving on a ramp or a field of field, it is necessary to take anti-slip measures such as paving furnace ash, draft.
(3) When the cold machine starts, due to the large fluid viscosity, the fluidity, the lubricating oil film between the various sports parts is insufficient, and the semi-liquid friction or even dry friction is generated after starting. At the same time, due to the low temperature, gasoline does not fully combustible, the lubricating oil on the wall of the gas cylinder wall reduces the lubricating effect of the lubricant, exacerbates the wear of the engine machine, and shortens the life of the engine. Therefore, in the case of poor heating conditions in the cold season, preheating should be performed, and the method of adding heat water is generally used to increase the temperature of the engine.
(4) In the forklift operation, various measures should be taken to keep the engine's normal operating temperature.
(5) The forklift stored in the open air should be purified or add antifreeze to avoid freeze-cracking.
(6) Cleaning the fuel tank, gasoline filter, a hydraulic oil, a hydraulic fuel tank, etc., prevent water freeze.
2, characteristics of low temperature conditions
(1) Due to the cold, the driver's work is inconvenient, it is easy to simplify the operation procedure, and there is more wear, and the upper and lower cars are easy to cause bumps.
(2) The cold season is large, the fog is more fog, and the snow is frozen, affects the driver's vision, and due to the snow, the adhesion is lowered, the wheel is easy to slip and slippery. In particular, the brake parking distance is longer, which brings difficulties to the driver's safety operation.
(3) Under low temperature conditions, the economic performance of the forklift decreased significantly, and the fuel consumption increased.
(4) Under low temperature conditions, the materials such as metal, rubber products on the forklift have a brittle tendency, and the mechanism and tire are easily damaged.
(5) Under low temperature conditions, the temperature is low, the oil has a large viscosity, and the fuel vaporization performance is poor, and the engine is difficult. In particular, the viscosity of the forklifts, drive bridges, transmissions, and engine in the engine are large, and thereby increasing operational resistance and reduces operational efficiency.
