28-33 Ton Amphibious Excavator

OVERVIEW

Features of 28-33 Ton Amphibious Excavtors

  • Large Pontoons RC300: Engineered for exceptional flotation, the RC300 pontoons provide 28.8 tons of buoyancy, enhancing stability in aquatic environments.
  • Wider Overall Structure (5000mm): The 5000mm-wide structure offers increased stability and operator safety by distributing weight more evenly, reducing tipping risks.
  • Three Separate Watertight Compartments per Pontoon: Each pontoon has three watertight compartments, improving safety and preventing sinking if one is damaged.
  • Triple Chain Track System: This system efficiently distributes track pressure, reducing wear and extending the undercarriage’s life, especially in tough terrains.
  • RD300 Positioning Pile Installation: With a total buoyancy of 32 tons when fully equipped, this installation boosts stability and operational capability.
  • High-Strength Steel Construction: Constructed from corrosion-resistant and wear-resistant high-strength steel for durability and long service life.
  • Fully Automatic Hydraulic Control System: Provides precise, efficient operation from the cab, enhancing overall productivity.
  • Custom 13 to 18-Meter Long Reach Boom: Extends from 13 to 18 meters, ideal for applications requiring extended reach.

Applications of 28-33 Ton Amphibious Excavators

  • Wetland and Marshland Excavation: Ideal for excavating and dredging in wetlands, marshes, and swamps where waterlogged or soft ground makes access difficult for standard machinery.

  • River and Lake Dredging: Used for dredging riverbeds, lakes, and other bodies of water to remove silt, sediment, and debris, improving water flow and navigation.

  • Land Reclamation:Used in land reclamation projects to create new land from bodies of water or to enhance existing land areas by adding fill material.

  • Coastal Protection: Helps in the construction and maintenance of coastal defenses, such as sea walls and breakwaters, to protect against erosion and storm surges.
