forklift mast is one of the core load-bearing components of electric forklifts, which directly affects the operation safety and service life of the whole equipment. Regular structural integrity inspection on the mast is a necessary basic work for all forklift operation teams, to avoid unnecessary safety risks during daily cargo handling process.
First, the pre-operation visual surface check part. Before each daily shift, operators should make a full visual scan on all exposed areas of the mast structure. They need to check for obvious deformation, cracks, or abnormal rust spots on the mast body, focus on the welded connection positions, and rule out tiny trace of cracking that may expand under heavy load. They also need to check the mast rollers, confirm there is no excessive wear or stuck phenomenon, and the running gap is kept within the reasonable range specified by the operation manual.
Second, the dynamic load operation verification part. Operators can run the mast up and down for multiple times under no-load state first, then carry out the same test under 30% to 50% of the rated load. During the whole process, they need to observe if there is abnormal noise, stuck jitter or lateral offset of the mast. They also need to confirm the tension of the lifting chain is uniform on both sides, no loose on single side, and the height limit device can trigger sensitively to stop the lifting process at the preset position.
Third, the periodic deep maintenance check part. It is recommended to arrange professional maintenance personnel to carry out full deep inspection according to the specified service cycle. The inspection items include confirming all fastening bolts of the mast are tightened to the standard torque, no aging bulge or liquid leakage on the matching hydraulic pipelines, and all lubrication points are filled with enough special lubricating grease.
