Precautions for the operation of internal combustion forklifts in winter

Precautions for the operation of internal combustion forklifts in winter

  • 2021-09-08
1. The internal combustion forklift should be warmed up in advance in winter. When the internal combustion forklift is in use, before the hydraulic system oil becomes hot, do not rush to use the hydraulic system to prevent damage to the hydraulic system components. In severe cases, pump explosion accidents may occur. After starting, the forklift must control the speed during the driving process, maintain the distance between vehicles, and avoid emergency braking. The braking interval in severe cold season is about 2 times longer than usual. It is strictly forbidden to turn sharply to relieve the impact force when turning to prevent the rigid structure from breaking.

Second, do a good job in seasonal maintenance of equipment. Detect the freezing point of the antifreeze liquid to make it 5℃ lower than the local minimum temperature; make the thermostat open temperature around 82℃; increase the battery electrolyte density to 1.280g/cm3; adjust the oil used in all parts of the machine in time for equipment working in the field It is necessary to install heat preservation measures, install the engine oil preheating device when necessary, and start the engine regularly to preheat the working systems of various parts in advance.

After starting the engine normally, there should be enough warm-up time to make it run 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, use buckets, shovel blades and various devices slowly. It is strictly forbidden to use large throttle, scraping, shoveling and pushing, etc., and the emphasis is on "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 the number of accidents caused by operating errors in winter is more than 65%. If the temperature is lower than -15°C, the engine cannot work immediately after starting, but the engine should be operated 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.
