The fork truck mast serves as the core load-bearing component of electric forklifts, directly supporting all lifting, stacking and low-position unloading operations in warehouse and industrial scenarios. Abnormal wear, unaddressed minor faults of the mast will not only reduce work efficiency, but also bring potential hidden risks to operation safety. This practical, easy-to-follow checklist is designed for frontline operators and on-site maintenance staff, no complex professional tools are required to finish the whole inspection process within a few minutes before daily shifts.

First, complete the static pre-operation inspection when the mast is fully lowered and the forklift is parked on flat, solid ground. Check all visible metal surfaces of inner and outer mast frames, confirm there is no obvious deformation, severe rust or crack on the structural parts. Check all connecting pins and fastening bolts, make sure no parts are loose, displaced or missing. Then inspect the lifting chains on two sides, confirm the tension of two chains stays consistent, no broken wires, obvious abrasion or stuck defects can be found. Next check all hydraulic hoses and connectors around the mast, observe if there is any oil seepage or leakage, confirm all sealing parts are in good condition without aging cracks.

Second, carry out dynamic load test after static check passes. Start the forklift with no load, lift the mast slowly to different working heights, observe the whole lifting and lowering process, confirm no abnormal noise, stuck jam or unsmooth sliding between inner and outer frames. After that, place half of the rated load on the forks, lift the mast gradually to the maximum working height, verify the lifting process stays stable, the load will not tilt or shift unexpectedly, the lowering speed keeps even without sudden free fall situation.

Third, do not ignore the regular maintenance reminders after each inspection. Operators need to record inspection results properly after each check, stop using the equipment immediately if any abnormal sign is found, and arrange professional maintenance staff to troubleshoot the fault in time, never perform assigned tasks with defective mast parts. Apply special lubricating grease to the mast sliding rails on a regular basis to reduce friction wear, so as to extend the whole service life of the mast assembly.
