Hey there! As a supplier of lorry loading cranes, I often get asked about the inspection procedures for these machines. In this blog, I'm gonna walk you through the key steps to ensure your lorry loading crane is in top - notch condition.
Pre - Inspection Checks
Before you even start the actual inspection, there are a few things you need to do. First off, gather all the necessary tools. You'll need things like a flashlight, a torque wrench, a measuring tape, and safety equipment such as gloves and safety glasses. Make sure you're familiar with the crane's manual. The manual provides specific instructions and specifications for your particular model of lorry loading crane.
Next, check the overall environment where the crane is located. Look for any signs of damage to the surrounding area, like cracks in the ground or nearby structures that could affect the crane's operation. Clear the area of any debris or obstacles that might interfere with the inspection or future crane use.
Visual Inspection
The visual inspection is the first real step in assessing the crane's condition. Start with the crane's exterior. Check for any visible signs of damage, such as dents, scratches, or rust. Rust can be a big problem as it can weaken the metal over time. Pay special attention to welds. Welds are critical for holding the crane together, so any cracks or signs of failure in the welds need to be addressed immediately.
Inspect the hydraulic hoses. Look for leaks, cuts, or bulges. A leaking hydraulic hose can not only lead to a loss of hydraulic fluid but also pose a safety hazard. Check the fittings on the hoses to make sure they're tight and not loose.
Examine the cables and ropes. Look for fraying, kinking, or excessive wear. The cables are responsible for lifting and moving the load, so any damage to them can be extremely dangerous. You can use a magnifying glass to get a closer look at the cable strands if needed.
Structural Inspection
The structure of the lorry loading crane is what gives it the strength to lift heavy loads. Check the boom. The boom is the long, extendable arm of the crane. Look for any signs of bending, twisting, or deformation. Measure the boom's length and compare it to the specifications in the manual. Any deviation could indicate a problem.
Inspect the outriggers. Outriggers are the supports that extend from the sides of the crane to provide stability. Make sure they're in good condition, with no cracks or damage. Check the pads at the end of the outriggers. These pads need to be flat and in good contact with the ground to prevent the crane from tipping over.
Check the turntable. The turntable allows the crane to rotate. Look for any signs of wear on the gears and bearings. Make sure the turntable rotates smoothly without any jerks or noises.
Hydraulic System Inspection
The hydraulic system is the heart of a lorry loading crane. Check the hydraulic fluid level. Low fluid levels can cause the system to malfunction. Use the dipstick or sight glass to check the level. If the fluid is low, add the appropriate type of hydraulic fluid as specified in the manual.
Inspect the hydraulic pump. Listen for any unusual noises coming from the pump. A noisy pump could indicate a problem with the internal components. Check the pump's mounting bolts to make sure they're tight.
Test the hydraulic valves. Operate the crane's controls to open and close the valves. Make sure they respond smoothly and that there are no leaks around the valves.
Electrical System Inspection
Many modern lorry loading cranes have electrical components for controls and safety features. Check the battery. Make sure it's fully charged and that the terminals are clean and tight. Corroded terminals can cause electrical problems.
Inspect the wiring. Look for any frayed wires, loose connections, or signs of overheating. Overheating wires can be a fire hazard. Check the electrical connectors to make sure they're properly seated.
Test the electrical controls. Operate the crane's controls to make sure all the functions work correctly. If any of the controls don't respond or behave erratically, there could be an electrical issue.
Load - Testing
Once you've completed all the previous inspections, it's time for load - testing. However, load - testing should only be done by trained personnel and in a safe environment. Start with a light load. Gradually increase the load as you monitor the crane's performance.
Pay attention to how the crane handles the load. Check for any signs of excessive swaying, tilting, or abnormal noises. Make sure the crane's lifting capacity is not exceeded. Refer to the crane's load chart, which provides information on the maximum load the crane can safely lift at different boom lengths and angles.
Post - Inspection Actions
After completing the inspection and load - testing, document all your findings. Keep a detailed record of the inspection, including any problems you found and the actions you took to address them. This documentation is important for maintenance scheduling and for compliance with safety regulations.
If you found any issues during the inspection, make the necessary repairs or replacements as soon as possible. Don't operate the crane if it has any unresolved problems. And always follow up with regular inspections to prevent future issues.
