The EOT crane inspection checklist is essential for the daily stable operation and safe production of EOT cranes. Long-term high-load operation of electric overhead travelling cranes can easily lead to wear and tear on key components, while improper inspection and maintenance may cause serious accidents such as wire rope breakage and brake failure. Therefore, whether in factories, warehousing and logistics centers, or workshop production sites, regular inspection and maintenance of EOT bridge cranes can effectively prevent equipment failures, improve production safety, and extend equipment lifespan. Next, this article will provide a detailed EOT crane inspection checklist to help you avoid dangers and extend the life of your equipment. Please continue reading:

How Often do EOT Cranes Need to be Inspected?
EOT crane inspection cycles are divided into pre-use inspection, daily inspection, weekly inspection, monthly inspection, and annual inspection. The EOT Crane inspection frequency is determined based on the user’s usage frequency, work class, operating environment, and national or industry standards. Below are the EOT crane inspection checklist content and inspection cycles:
1. EOT Overhead Crane Pre-Use Inspection Checklist
| Inspection Items | Inspection Contents |
|---|---|
| Lifting Mechanism | Check the lifting mechanism for cracks, deformation, broken wires, corrosion, etc., and check whether the trolley brakes and limit switches are working sensitively. |
| Electrical System | Check that the power connection is secure, and that the control buttons are sensitive, odorless, sparking, or loose. |
| Safety Devices | Check the overload protector, alarm, and emergency braking device for their sensitivity. |
| Track and Running Mechanism | Check the track for any obstructions. The overhead travel mechanism and trolley should run smoothly without any abnormal noises or vibrations. |
| Warning Signs | Check whether the safety warning signs and load capacity nameplates are clear and complete. |
| Lubrication and Cleaning | Check that all lubrication points have sufficient grease. Remove debris from the rails, hooks, and drums. |
| Lighting and Operating Area | Check whether the lighting in the operating area is sufficient and whether there are any people or obstacles in the work area. |
| Trial Run | Operators control the equipment for a no-load trial run, observing whether the lifting, traveling, steering, and braking are normal. |
2. EOT Crane Daily Inspection Checklist
| Inspection Items | Inspection Contents |
|---|---|
| External Structure | Inspect the main beams, end beams, connecting bolts, and welds for integrity, and check for cracks, deformation, or looseness |
| Hook | Check if the wear on the hooks exceeds the standard |
| Wire Rope | Inspect wear, lubrication, and winding neatness |
| Brakes | Inspect brake clearance and pad wear. |
| Electrical Components | Inspect cable wear, insulation aging, and wiring tightness. |
| Lubrication | Check if the lubricant is applied evenly to the transmission parts. |
| Metal Structure | Inspect welds, connecting bolts, and track alignment. |
| Cable Reel | Inspect the Cable reel for knots, detachment, wear, or jamming. |
3. Weekly EOT Crane Inspection Checklist
| Inspection Items | Inspection Contents |
|---|---|
| Metal Structure and Connecting Parts | Inspect the metal structure for cracks, deformation, or abnormal wear, and check whether connecting bolts and pins are loose or detached. |
| Crane Spreader | Check that the crane Spreader’s all parts are intact and undamaged. |
| Braking System | Check if the braking action is sensitive and the brake springs are intact. |
| Warning Signs | Check that the safety warning signs are clear and complete. |
| Safety Devices | Check whether the lifting limit switches, travel limit switches, anti-collision devices, overload protectors, and other devices are sensitive and reliable. |
| Noise and Vibration | Check the equipment for any abnormal noises, vibrations, or shaking during operation. |
| Track and End Beam | Check the track’s flatness and bolt tightness. Ensure the end beam and track are properly aligned and there is no rail wear. |
| Control System | Check the sensitivity of the operating handles, buttons, remote control, and emergency stop switch. |
4. EOT Overhead Crane Monthly Inspection Checklist
| Inspection Items | Inspection Contents |
|---|---|
| Metal Structure | Measure whether the deflection value is within the allowable range. |
| Connectors and Bolts | Inspect connectors for missing or worn parts, and check the fasteners for damage. |
| Hook Assembly | Measure whether the change in hook opening exceeds the standard. |
| Wire Rope | Inspect the wire rope for broken wire ratio, wear depth, rust condition, and lubrication status. |
| Pulley System | Inspect the pulley rotation flexibility, groove wear depth, and the integrity of the protective cover. |
| Braking System | Check if the braking action is smooth. |
| Transmission System | Check the reducer oil level, gear meshing, coupling for looseness, and listen for abnormal noise or vibration. |
| Electrical System | Check the motor for signs of overheating. |
| Cables | Inspect the cables for dust accumulation, oxidation, or loosening. |
| Travel Mechanism | Inspect wheel wear, bearing lubrication, track alignment, and the integrity of the anti-collision buffers. |
| Lubrication System | Inspect, replace, or replenish the gearbox lubricating oil. |
| Metal Exterior Surfaces | Inspect metal surfaces for areas with peeling paint, rust, or damaged coatings, and promptly touch up with paint for protection. |
| Load Capacity Test | Conduct a trial run under rated load and observe whether the lifting, braking, and operation are stable. |
| Records and Maintenance Reports | Fill out the inspection record, record the problems found and the repair measures, and archive it for future reference. |
5. Annual Overhead EOT Crane Inspection Checklist
| Inspection Items | Inspection Contents |
|---|---|
| Metal Structures | Ultrasonic or magnetic particle testing is performed on critical welds. |
| Wire Rope and Hook Assembly | Measure the wear rate of the wire rope diameter and check the hook for cracks, deformation, or excessive wear. |
| Operating Mechanism | Inspect the wear of each part and tighten the bolts. |
| Lifting Mechanism | Inspect the temperature rise, noise, and vibration of the lifting mechanism, and test the accuracy and response time of the limit switches. |
| Electrical Systems | Comprehensive testing of electrical control cabinets, wiring insulation, cable reels, and grounding systems. |
| Safety Devices | Test overload protection, emergency stop, limit switch, and anti-collision device. |
| Lubrication System | Check that all lubrication points are supplying oil normally, replace the gearbox lubricating oil, and check for oil seal leaks. |
| Motor and Inverter | Check the motor’s insulation resistance, bearing operating condition, and whether the cooling fan is functioning properly. Verify that the inverter’s parameter settings match the operating conditions. |
| Corrosion Protection | Inspect areas with peeling paint and rust, and repaint accordingly. |
| Load Capacity Testing | Perform rated load and overload tests (usually 125%) to verify whether the structural strength and braking performance meet the standards. |
| Record keeping | Check that the nameplate information, maintenance records, and operation manual are complete. Affix the latest inspection certificate. |
| Safety Training | Check the operators’ certification status. Verify the completeness of daily and monthly inspection records. |
