Do not operate the hydraulic system before the oil in the hydraulic system becomes hot. Otherwise, the hydraulic components will be damaged, and the pump will burst in serious cases. The forklift shall control the speed, keep the distance and avoid emergency braking. The braking interval in the severe cold season is about twice longer than that in regular times. It is forbidden to turn sharply to reduce the impact force during turning to prevent the fracture of rigid structural members.
Do an excellent job in the seasonal maintenance of the equipment, and detect the freezing point of the antifreeze to make it 5 ℃ lower than the local minimum temperature; Keep the opening temperature of the thermostat at about 82 ℃. Increase the battery electrolyte density to 1.280y/cm3; Timely adjust the oil used by each part of the machine and install thermal insulation measures for equipment working in the field. If necessary, install the engine oil preheating device, and start the engine regularly to preheat the working system of each part.
After starting the engine, there should be enough time to warm up the engine and make it run under low speed and light load until the engine, transmission, hydraulic system, and oil in the final transmission become hot. When the equipment is working, the operation of the bucket, shovel, and various devices to be slow, prohibit the big throttle impact, scraper, and push, etc., the essential requirements are “Steady” and “Slow.” Winter is the high accident season, accounting for about 80% of the total accidents in the whole year, and the accidents caused by operational mistakes in winter are more than 65%. If the air temperature is below-15 °C, the engine can not start immediately, but the engine should be 1000-1100r/min running 10-15min, and the transmission is neutral. Therefore, it is necessary to regularly check the forklift machine’s rigid connection and the main bearing parts. The road surface is too slippery in winter ice and snow weather. We must pay attention to safety.
