The establishment and strict implementation of a systematic daily inspection and preventive maintenance system is a key management measure to ensure the safe, reliable and efficient operation of electric forklifts and maximize their service life.The core of this system is to transform passive maintenance after maintenance work is engaged into proactive prevention in advance, and through regular inspection and maintenance, potential problems are discovered and dealt with in a timely manner to prevent small failures from turning into major downtime.Daily inspections, usually performed by forklift operators before the daily shift or start of work, should form a standardized inspection form.The inspection content covers basic safety items: such as checking whether the tires are over-worn or damaged; testing whether the brake function is normal; checking whether the lights and horns are effective; and observing whether the door frame and fork are significantly deformed or cracked.For electric systems, it is necessary to check the instrument panel for alarm instructions, whether the control handle is flexible in operation, and visually check whether the battery surface is clean and the connection terminal is corroded or loose.

Preventive maintenance is based on daily inspections, and more in-depth and periodic professional maintenance should be based on the maintenance manual provided by the equipment manufacturer, combined with the actual use intensity of the forklift (working hours) to make a plan.Its core points include several key systems: first, the maintenance of the power battery system.For lead-acid batteries, this includes regularly checking the electrolyte level and replenishing distilled water (non-maintenance-free batteries), cleaning the battery surface and terminals, equalizing charging, and conducting capacity tests.For lithium batteries, it is mainly to check the status of the battery management system, the tightness of the connector, and the cleanliness of the cooling channel (if any).Secondly, it is the inspection of the drive and hydraulic system, such as checking whether the operating sound and temperature rise of the drive motor and the hydraulic pump motor are normal, checking the oil level and cleanliness of the hydraulic oil and replacing it on time, and checking the oil cylinder and pipeline joints for leakage.In addition, it is the adjustment and lubrication of the steering and braking system, checking the steering flexibility and brake pad wear, and filling each lubrication point with a specified type of grease.

The vitality of the system lies in implementation and recording.Enterprises should clarify the persons responsible for daily inspections and regular maintenance at all levels, and provide necessary training to ensure that they master the correct inspection and maintenance methods.All maintenance activities, whether it is a simple daily inspection or a complex regular maintenance, must be recorded in detail, including the date, time, inspection items, problems found, measures taken and replacement parts.These record files are not only the “medical record” of the health status of the equipment, which provides a historical basis for fault diagnosis, but also an important data support for evaluating the effectiveness of equipment management, planning future maintenance budgets, and making equipment update decisions.A sound preventive maintenance system, although it requires a certain amount of manpower and material costs, can effectively reduce production interruptions caused by sudden failures, avoid expensive major repairs, and ensure operational safety. In the long run, it is a strategic investment to reduce the total cost of the whole life cycle of equipment and increase the return on investment.
