A. Is there a difference between a crawler excavator and an amphibious excavator when it comes to their operation?

A crawler excavator is a type of construction vehicle that runs on tracks and is used for digging, lifting, and hauling materials.

An amphibious excavator is a type of vehicle that is designed to work both on land and in water. It is equipped with flotation devices, which allow it to float in the water and move around more easily. The amphibious excavator is mostly used for digging and dredging in marshy or muddy areas. The crawler excavator, on the other hand, is better for construction sites.


B.How do you operate an amphibious excavator in a proper way?

  1. Before operating an amphibious excavator, make sure to read and understand its operator’s manual.
  2. Check the fuel tank, engine oil, coolant, and hydraulic fluid levels of amphibious excavator before starting the engine.
  3. Make sure to inspect the machine for any signs of damage or leaks.
  4. When using the amphibious excavator of 20 tons in water without side pontoon, ensure that the water level does not exceed at most 1.8 meters of the track shoe of the machine. If in any case is exceeded, side pontoons with or without positioning piles are needed for stability.
  5. Adjust the speed of the excavator depending on the terrain, soil type, and water currents.
  6. Make sure to keep the bucket angles and the bucket depth of the amphibious excavator to avoid bogging down (causing something to sink into the wet ground) the machine.
  7. Use the tracked drive option when operating the excavator in both shallow and deep water.
  8. After every use, inspect the amphibious machine for any signs of wear and tear.
  9. Finally, always ensure to follow the safety precautions mentioned in the operator’s manual of the machine.
