The Hitachi EX-700H is a heavy duty crawler excavator with a backhoe attachment. It is modified appropriately so as it can operate in landing bay and beach worksites up to 1.5m water depth. It is utilized in construction works where it is required to:

  • Excavate trenches for the protection of the cables or the pipes 
  • Backfill trenches 
  • Installation of articulated pipes 
  • Installation of mattresses 

Some of its advantages are mentioned below:

  • Exceptional reliability 
  • Ability to operate 24/7 with minimum maintenance
  • Operate in very hard terrains since it has a high digging force 
  • Operate at uneven territories due to its excellent stability 
  • Ensure maximum operator safety 
  • Enhanced with built-in toughness 
  • Operate safely up to 1.5m water depth 

Due to the harsh environments that the excavator usually operates during landing site executions, i.e. near sea and coasts, its electric and hydraulic circuits are modified to minimize deterioration and to avoid operational problems.
