Do not operate the hydraulic system before the hydraulic system oil becomes hot, otherwise the hydraulic components will be damaged, and a pump explosion accident will occur in severe cases. The forklift must control the speed of the vehicle during driving, maintain the distance between vehicles, and avoid emergency braking. The braking interval in the cold season is about twice as long as usual. It is forbidden to turn sharply and reduce the impact force when turning to prevent the rigid structural parts from breaking.
Seasonal maintenance of the equipment should be done, the freezing point of the antifreeze should be detected to make it 5 ℃ lower than the local lowest temperature; the thermostat opening temperature should be around 82 ℃; the battery electrolyte density should be adjusted to 1.280g / cm3; Adjust the oil used in each part of the machine in a timely manner, install heat preservation measures for equipment working in the field, install an engine oil preheating device when necessary, and start the engine regularly to preheat the working system of each part.
After starting the engine normally, there should be enough warm-up time to run it at low speed and light load until the oil in the engine, transmission, hydraulic system and final drive becomes hot. When the equipment is working, the bucket, blade and various devices should be operated slowly. The impact, scraping, shoveling and pushing of the large throttle are prohibited. The key requirements are "stable" and "slow". Winter is the season with a high incidence of accidents, accounting for about 80% of the total accidents throughout the year, while accidents caused by operational errors in winter account for more than 65%. If the temperature is lower than -15 ℃, the engine can not work immediately after starting, but the engine should be run at 1000-1100r / min for 10-15min, and the transmission is in neutral. Therefore, it is necessary to regularly check the rigid connection of the forklift machine and the main load-bearing parts.
