Excavators often need long-distance transportation between different construction sites, using flatbed trucks, trailers, ships, or trains. During loading, unloading, and transportation, improper operation or poor fixation can easily cause rollover, collision, structural damage, and even safety accidents. This guide provides complete safety specifications for loading, unloading, fixation, inspection, and emergency treatment to ensure the safe transition of excavators.
Before transportation, confirm the transportation plan and vehicle conditions. Select a flatbed truck or trailer with sufficient load capacity, reliable brakes, and complete fixation devices. Check the flatness, firmness, and anti-skid performance of the carriage plate. Confirm the road conditions, bridge load limits, and height limits of the transportation route to avoid overheight, overweight, and overwidth violations. For ultra-long-distance or highway transportation, go through relevant transportation approval procedures.
Prepare necessary tools and equipment: steel wire ropes, chains, tensioners, anti-skid pads, wooden piers, warning signs, etc. Ensure that the fixation tools are in good condition without wear, deformation, or damage. The site for loading and unloading should be flat, solid, and free of soft soil to prevent collapse and rollover. Set up warning areas to prohibit unrelated personnel from entering.
Loading operation must be standardized and stable. The excavator drives onto the flatbed truck slowly at a low speed, with the boom facing the transportation direction and the bucket placed firmly. Adjust the position so that the center of gravity is in the middle of the carriage, not too far forward or backward. Do not turn sharply or accelerate suddenly during boarding to avoid sideslip. Use the boom to assist in adjusting the attitude if necessary, but do not use excessive force.
After the excavator is in place, carry out firm fixation. Use steel wire ropes or chains to fix the undercarriage frame, boom, and bucket to the carriage body, at least 4 to 6 fixed points. Use tensioners to tighten the ropes to prevent loosening during transportation. Place anti-skid pads or wooden piers under the track to prevent sliding. The hydraulic cylinders should be in a relaxed state, not fully extended or locked, to avoid stress damage during bumps.
Protective measures for key components. Lower the boom and arm to a low position, and place the bucket on the carriage to reduce the center of gravity and wind resistance. Wrap the hydraulic cylinder rods with protective cloth to prevent scratches and collisions during transportation. Cover the cab, instrument, and engine with a waterproof and dustproof cloth to avoid damage from wind, sand, and rain.
Check the fixation repeatedly before departure. Check whether each steel wire rope and chain is tight, whether the track is fixed reliably, and whether the whole machine is stable. During long-distance transportation, stop and check the fixation condition every 1 to 2 hours, especially after bumpy road sections, and retighten the loose ropes in time.
Unloading operation safety is equally important. The unloading site should also be flat and solid. Loosen the fixation devices in sequence, not all at once, to prevent sudden sliding. Start the engine, warm it up, and check the basic functions. Drive the excavator off the flatbed truck slowly at a low speed, keeping the body stable. Avoid sudden braking and turning during unloading.
Transportation safety precautions. The transportation vehicle should drive at a medium speed, avoid sudden acceleration, deceleration, and sharp turns, and reduce bumps. When driving on highways or bumpy roads, reduce the speed appropriately. Avoid passing through high-temperature, open-fire, and strong vibration areas to prevent safety hazards.
Special attention for water and railway transportation. For ship transportation, strengthen the fixation according to the shaking characteristics of the ship, and add anti-slip and anti-tilt devices. For railway transportation, comply with railway transportation regulations, fix the position accurately, and prevent displacement during operation.
After transportation, conduct a comprehensive inspection of the excavator. Check whether the structural parts, hydraulic pipelines, electrical wiring, and cab are damaged or loose. Check the hydraulic oil, engine oil, and fuel for leakage. Test the basic functions such as walking, rotation, and lifting to ensure that the excavator can be put into use normally.
In summary, the safety protection of excavator long-distance transportation focuses on reasonable loading position, firm fixation, speed control, and repeated inspection. Strictly following the specifications can effectively avoid accidents and ensure the safety of personnel and equipment.
