Forklifts in construction sites, brick factories, and concrete mixing plants work in high-dust, gravel, and heavy-load conditions for a long time. Dust easily enters the engine, hydraulic system, and bearings, causing serious wear and blockage. Heavy loads and rough roads accelerate tire, frame, and mast wear. This guide provides anti-dust, anti-wear, and heavy-load maintenance measures to ensure the stable operation of forklifts in harsh construction conditions.
Air intake and engine anti-dust protection. Dust entering the engine causes cylinder wear and power attenuation. Use high-efficiency two-stage air filters and clean or replace filter elements frequently. Check the air intake pipe for tightness daily to avoid unfiltered dust inhalation. Use high-grade anti-wear engine oil and shorten the oil change cycle to reduce wear.
Hydraulic system anti-dust and anti-pollution maintenance. Dust causes wear of pumps, valves, and cylinders, leading to oil leakage and slow movement. Use high-sealing hydraulic oil tanks and filters. Check for oil leakage daily; replace aging seals. Shorten the hydraulic oil change cycle and avoid disassembling pipelines in dusty environments to prevent dust entry.
Mast, chain, and bearing anti-dust lubrication. Dust accelerates chain and guide rail wear. Clean and lubricate chains and guide rails daily with anti-dust and anti-wear grease. Check chain tension and wear daily; replace worn chains in time. Install dust covers on bearings to prevent dust entry and jamming.
Tire and chassis anti-wear and anti-collision protection. Use thickened wear-resistant tires suitable for construction sites. Check for cuts and embedded gravel daily. Keep proper tire pressure. Reinforce the chassis and install anti-collision blocks to reduce collision damage. Clean dust and gravel on the chassis daily to reduce wear.
Brake system anti-dust and safety maintenance. Dust causes abnormal wear of brake pads and weak braking. Clean the brake system daily to remove dust. Check brake pad wear and braking effect daily; replace worn parts in time. Ensure reliable braking to avoid safety accidents.
Frame and body anti-collision and anti-rust maintenance. Construction site collisions easily cause frame deformation and paint peeling. Repair damaged paint in time to prevent rust. Reinforce vulnerable parts. Check frame welds daily for cracks; repair them immediately.
Battery and electrical system anti-dust protection (electric forklifts). Dust causes poor contact and short circuits. Clean batteries, controllers, and wiring harnesses daily. Check terminals and connectors for dust and corrosion; apply anti-dust grease. Keep electrical boxes sealed to prevent dust entry.
Daily cleaning and regular maintenance. Clean the whole machine with high-pressure water daily to remove dust and concrete residues. Conduct a comprehensive lubrication and inspection every week. Change oil and filters monthly to ensure the forklift is in good condition.
Reasonable operation reduces wear. Drive at low speed on rough roads, avoid sudden braking and turning, and do not overload. Avoid driving on sharp gravel to reduce tire and chassis wear.
In summary, forklift maintenance in construction conditions focuses on dust prevention, enhanced lubrication, wear resistance, and safety protection. Strict implementation can effectively extend service life and reduce failures.
