Do not operate the hydraulic system until the oil in the hydraulic system is hot, otherwise the hydraulic components will be damaged, and the pump explosion accident will occur in severe cases. Electric forklifts should control the speed, keep a distance, and avoid emergency braking. In the severe cold season, the braking interval is about 2 times longer than usual. Do not turn sharply, reduce the impact force when turning, and prevent the rigid structure from breaking.
Do a good job in seasonal maintenance of the equipment, check the freezing point of the antifreeze, and make it 5°C lower than the very low local temperature; let the thermostat turn on at about 82°C; adjust the density of the battery electrolyte to 1.280g/cm3; adjust it in time For the oil used in each part of the machine, install insulation measures for the equipment working on site, install oil preheating device if necessary, start the engine regularly, and preheat the working system of each part.
After the engine is started normally, there should be sufficient warm-up time for it to run at low speed and light load until the oil in the engine, transmission, hydraulic system and final drive is warm. When the equipment is working, operate the bucket, shovel and various devices slowly. It is strictly forbidden to use the large throttle to impact, scrape, and push. The key requirements are "steady" and "slow".
Winter is a high accident season, accounting for about 80% of the total number of accidents in the year, and more than 65% of the accidents are caused by operational errors in winter. If the air temperature is lower than -15°C, the engine cannot work immediately after starting, but it should run at 1000-1100 rpm for 10-15 minutes with the transmission in neutral. Therefore, it is necessary to regularly check the rigid connections and main load-bearing parts of the forklift machinery.
