Operating a trackhoe (or tracked excavator) can be a demanding task, especially when accidents or unexpected situations occur. One of the most concerning situations is when a trackhoe tips over onto its side. In such cases, operators must follow a specific startup procedure to ensure the machine is safe to operate and that no damage has occurred. This article provides a detailed guide on what to do when a trackhoe goes on its side and how to safely restart the machine.
Initial Assessment: Is It Safe to Start the Trackhoe?

1. Ensure the Area is Safe
   Before attempting to start the trackhoe, ensure that the surrounding area is clear of any hazards. Check for any obstructions, loose debris, or equipment that could cause additional accidents. It is crucial to ensure that no one is in the vicinity and that the area is safe for you to approach the machine.
   
2. Check for Fuel and Hydraulic Leaks
   When a trackhoe tips over, there’s a risk of fuel, hydraulic fluid, or other liquids leaking from the machine. Immediately inspect the machine for any signs of leaks. If any fluid is leaking, do not attempt to start the machine. Instead, address the leak by securing the fluid and ensuring there are no ongoing hazards. It’s essential to avoid starting the machine if fluid is leaking to prevent further damage or potential fire hazards.
   
3. Inspect for Structural Damage
   Check the machine for any visible structural damage, such as bent tracks, broken hydraulic lines, or a misaligned boom. If any critical components are damaged or compromised, it’s crucial to stop and seek professional assistance before attempting to start the machine.
   

1. Use a Crane or Other Lifting Equipment
   If the trackhoe has fallen on its side, it is likely too dangerous to attempt to right it without assistance. Using a crane, lifting straps, or other heavy equipment designed for this purpose is the safest method. A certified operator should control the equipment to carefully lift the machine back into its upright position.
   • Lifting the Machine: Ensure that the lifting process is slow and controlled. Take time to stabilize the machine before attempting to lift it fully. If necessary, use blocking materials or mats to stabilize the machine once it is back upright.
     
2. Avoid Manual Lifting
   Never attempt to manually lift or tilt the trackhoe back into position. Doing so could lead to injury or cause further damage to the machine.
   

1. Hydraulic System Check
   The hydraulic system is vulnerable when a machine tips over. Ensure that there is no air in the lines or damage to the hydraulic cylinders. Start the machine and move the boom and arm to check for proper hydraulic function. If any abnormal sounds, jerky movements, or delays in response are noticed, stop the machine immediately and investigate further.
   
2. Engine Oil and Fluids
   Inspect the engine oil and other fluid levels, such as coolant and transmission fluid. Tipping over can cause fluid levels to shift or become unbalanced. If the oil or fluid levels appear low, top them off according to the manufacturer’s guidelines. Ensure that the oil has not been contaminated with water or dirt.
   
3. Electrical System
   Check the electrical system for any disconnected wires or damaged components. The tipping of a trackhoe can cause electrical cables to become damaged, potentially leading to short circuits or failure of vital systems.
   

1. Turn the Key to the "On" Position
   Once the machine has been inspected and is deemed safe to operate, turn the ignition key to the “on” position. This will engage the system’s electronics and allow you to assess if the electrical systems are working properly.
   
2. Check for Warning Lights
   Ensure that no warning lights are illuminated on the dashboard, as this could indicate a fault with the machine’s systems. If any warning lights remain on, consult the machine’s manual or diagnostic tool to identify the problem before proceeding.
   
3. Start the Engine
   Start the engine as you normally would, paying attention to any unusual sounds or delays in engine operation. Listen for abnormal noises such as grinding, sputtering, or irregular engine sounds, as these could indicate internal damage or operational issues. If the engine starts smoothly, proceed with further checks.
   
4. Test the Controls
   After the engine has started, engage the trackhoe’s controls to check all movements. Operate the boom, arm, and tracks to ensure that everything moves smoothly. Pay close attention to the speed and responsiveness of the hydraulic system. If any movements are jerky or unresponsive, it could indicate a problem with the hydraulic system or internal components.
   

1. Consult the Operator’s Manual
   If you’re unsure about any aspect of the recovery or startup procedure, consult the operator’s manual for detailed instructions specific to your trackhoe model. The manual may provide vital information on troubleshooting or additional precautions that are unique to the machine.
   
2. Seek Professional Help If Necessary
   If you encounter any issues or if there is visible damage to the machine, it’s advisable to contact a professional technician or dealer for a thorough inspection and repair.
