As a trusted supplier of aerial work trucks, I understand the critical importance of conducting thorough inspections before putting these vehicles into operation. Aerial work trucks, also known as cherry pickers or boom lifts, are essential equipment in various industries such as construction, maintenance, and utilities. Ensuring their safety and proper functioning is not only a legal requirement but also a moral obligation to protect the lives of operators and those working in the vicinity. In this blog post, I will share a comprehensive guide on how to inspect an aerial work truck before use.
Pre - Inspection Preparation
Before starting the actual inspection, gather all the necessary tools and materials. You will need a flashlight to check hard - to - reach areas, a tire pressure gauge, a multimeter to test electrical systems if needed, and a copy of the vehicle's maintenance manual. Familiarize yourself with the specific model of the aerial work truck you are inspecting, as different models may have unique features and requirements.


Visual Inspection
- Exterior of the Truck
- Walk around the entire truck and look for any signs of damage, such as dents, scratches, or cracks. Pay special attention to the frame, as any structural damage can compromise the stability of the vehicle. Check for loose or missing body panels, which could pose a hazard during operation.
- Inspect the tires for wear and tear. Look for uneven tread wear, cuts, or bulges. Use a tire pressure gauge to ensure that the tires are inflated to the recommended pressure. Under - inflated or over - inflated tires can affect the handling and safety of the truck.
- Examine the lights, including headlights, taillights, turn signals, and hazard lights. Make sure they are all functioning properly. Broken or non - functioning lights can lead to accidents, especially when working in low - light conditions.
- Aerial Work Platform
- Check the boom or lift mechanism for any signs of bending, rust, or corrosion. The boom is a critical component of the aerial work truck, and any damage to it can be extremely dangerous. Look for loose bolts or pins on the boom joints and make sure they are tightened properly.
- Inspect the platform itself. Ensure that the guardrails are intact and securely attached. Check for any holes or weak spots in the platform floor. The platform should be clean and free of debris that could cause slips or trips.
- Examine the hydraulic hoses for leaks. Hydraulic fluid leaks can not only reduce the performance of the lift but also pose a fire hazard. Look for wet spots or signs of hydraulic fluid on the hoses, connections, and cylinders.
Fluid Checks
- Engine Fluids
- Check the engine oil level using the dipstick. The oil should be at the appropriate level and have a clean appearance. If the oil is dirty or low, it may indicate engine problems or a need for an oil change.
- Inspect the coolant level in the radiator. Make sure it is at the correct level and that there are no signs of leaks. Low coolant levels can cause the engine to overheat, leading to serious damage.
- Check the brake fluid level in the reservoir. The brake fluid should be within the recommended range. If the level is low, it could indicate a leak in the brake system, which requires immediate attention.
- Hydraulic Fluid
- The hydraulic system is responsible for powering the boom and lift mechanism. Check the hydraulic fluid level in the reservoir. Ensure that it is at the proper level and that the fluid is clean. Contaminated hydraulic fluid can cause damage to the hydraulic components and reduce the efficiency of the lift.
Electrical System Inspection
- Battery
- Inspect the battery for corrosion on the terminals. Corrosion can prevent the battery from charging properly and can also cause electrical problems. Clean the terminals if necessary using a wire brush and a mixture of baking soda and water.
- Check the battery voltage using a multimeter. A fully charged battery should have a voltage of around 12.6 volts. If the voltage is significantly lower, the battery may need to be recharged or replaced.
- Wiring and Controls
- Look for any loose or damaged wiring throughout the truck, especially around the controls and the aerial work platform. Loose wiring can cause malfunctions in the electrical system, leading to unexpected movements of the boom or lift.
- Test the controls in the cab and on the platform. Make sure that all the functions, such as raising and lowering the boom, extending and retracting the lift, and rotating the platform, work smoothly and as expected. Any abnormal or jerky movements could indicate a problem with the control system.
Safety Equipment Inspection
- Emergency Stop Buttons
- Locate and test the emergency stop buttons on the truck and the aerial work platform. These buttons are designed to quickly stop the operation of the vehicle in case of an emergency. Make sure they are easily accessible and functioning properly.
- Fall Protection Equipment
- If the aerial work truck is equipped with fall protection equipment, such as harnesses and lanyards, inspect them for damage. Check for frayed ropes, broken buckles, or worn - out components. The fall protection equipment should be in good condition and meet the relevant safety standards.
Operational Tests
- Engine and Transmission
- Start the engine and let it idle for a few minutes. Listen for any abnormal noises, such as knocking or rattling. Check the engine temperature gauge to ensure that the engine is not overheating.
- Shift through the gears of the transmission to make sure it shifts smoothly. Any grinding or hesitation during gear changes could indicate a problem with the transmission.
- Aerial Work Platform Operation
- Slowly operate the boom or lift mechanism through its full range of motion. Observe the movement for any smoothness or jerkiness. Check for any unusual noises or vibrations during operation. Make sure that the boom can reach the intended height and position accurately.
- Test the platform's leveling system, if applicable. The platform should be able to level itself automatically or manually, depending on the design of the truck. An unlevel platform can be dangerous for the operator.
Post - Inspection Actions
If any issues are found during the inspection, they should be addressed immediately. Minor issues, such as loose bolts or a blown fuse, can often be fixed on - site. However, more serious problems, such as structural damage or hydraulic system failures, may require professional repair.
Keep a detailed record of the inspection, including the date, time, and any findings. This record can be useful for maintenance scheduling and for demonstrating compliance with safety regulations.
