Used Amphibious Excavators

Overview

Amphibious excavators are specialized machines built to work on soft ground, marshes, swamps and shallow water. They use wide, sealed pontoons or modular floats under the undercarriage to spread weight and stay buoyant, allowing standard hydraulic excavator functions in environments where conventional tracked machines would sink. They’re used for dredging, wetland restoration, pipeline work and flood control where flotation, low ground pressure and mobility in waterlogged terrain are essential.

FAQ

What should I check when buying a used amphibious excavator?

Inspect pontoons for corrosion, leaks or repairs, check seal integrity and anodes, examine undercarriage and track condition, verify hydraulic hoses and cylinders, review engine hours and service records, and test operation in water or soft ground if possible.

How do I ship an amphibious excavator safely?

Plan transport with a heavy-equipment carrier experienced with floats; remove or secure pontoons if required, use appropriate cranes for loading, confirm weight/width permits, protect hydraulics and electronics, and document pontoons and hull condition before transit.

What maintenance does an amphibious excavator need?

Regularly inspect and repair pontoons, replace sacrificial anodes, check seals and drain plugs for water ingress, service hydraulic fluid and filters, grease pins and bearings, monitor cooling systems, and follow a strict corrosion-protection schedule.
