• An amphibious excavator, also known as a marsh buggy, is an excavator specifically designed to maneuver in marshes, swampy areas and soft terrain, as well as to float on water.
• The physics behind the amphibious excavator lies in the hermetically sealed pontoons, designed based on Archimedes’ principle. Coupled with its large foot print, this creates an extremely low ground pressure.
• The machine is capable of tracking in both dry, soft and swampy areas with little or no risk of being stuck in the mud.
• The amphibious excavators has proven itself and performed exceedingly well in the followings applications :
� Dredging
� Landscaping
� Erosion control and prevention
� Deepening of waterways and river deltas
� Maintenance and cleaning of rivers, lakes, shorelines, ponds, etc
Located in Singapore

Multi-Synchronous Drive System | |||
Proprietary multi-synchronous drive motor design. | |||
Motors are mounted on front and rear of each pontoon. | |||
It offers superior tracking power as compared to a single motor design. A similar concept that is applied to a | |||
full time 4×4 gear system of a land vehicle. | |||
Swampy areas are not necessary flat, and one will realize the full potential when tracking on uneven and high | |||
viscosity muddy terrains. | |||
Hydraulic Extendable & Retractable Pontoons | |||
Extension and retraction of pontoons “on the fly”. | |||
When fully extended, it offers the extra stability needed when situation calls for. | |||
Provide the flexibility of narrow track width when fully retracted when needs arises. | |||
Designed for ease of land transportation of complete machine by trailer when pontoons are fully retracted. | |||
Higher ROI through long term saving of manpower, crane hiring and other logistical cost. | |||
Hydraulic extendable pontoons is a standard feature for 12 ton class and below amphibious machine. | |||
Non Hydraulic Extendable | |||
For non hydraulic extendable design, there are 2 separate locking pin positions for each pontoon on the horizontal | |||
mounting beams. | |||
Users can choose their desired overall track width during the installation process. | |||
Pontoon Design & Construction | |||
Each pontoon has 2 bulk heads with 3 water tight compartments which are hermetically sealed. | |||
The pontoon is designed with sufficient displacement applying Archimedes’ Principle to ensure the entire | |||
amphibious excavator is able to float on water as a safety feature. | |||
Each pontoon comes with manholes for easy access to its interior for servicing and maintenance. | |||
Supplementary Pontoons and Spuds | |||
Supplementary pontoons can be added on each side to boost stability in deeper water operation. | |||
Spud piles attach to supplementary pontoons help to overcome buoyancy effect, it offers added stability and | |||
enhanced operability. | |||
Pontoons are designed and built with provision for future addition of supplementary pontoon and spud system. | |||
Future proof in design. | |||
Track Chain | |||
The track chain is constructed with premium grade steel imported from Europe. | |||
The track chain, being one of the most critical component require high level of precision and consistency in the | |||
manufacturing process. | |||
Each track link plate is CNC laser cut to utmost precision of the highest standard. | |||
The track shoe is supported by 2 or 3 strands of track chain offers the advantage of uniform pulling force and | |||
superior weight distribution across each track shoe. | |||
The hard working sprockets, rollers and pins are made from hardened steel, reducing the frequency of | |||
replacement and costly down time. | |||
Rollers are traveling on a strip of wear resistant steel plate (Hardox), prevent premature wearing to the | |||
pontoons. | |||
Every roller has an embedded bushing (in red). The bushing protects and extends the useful working life of the | |||
track chain. | |||
Replaceable Sprockets | |||
Sprockets are machined to high precision. | |||
Induction hardened for durability. | |||
Each sprocket is bolted onto the axle which can be easily replaced individually. | |||
Replacement process is simple and perfect alignment is guaranteed. | |||
For competitors’ weld-on sprocket design, replacement is much more tedious, complicated and costly. | |||
Track Shoe | |||
Track shoes are steel fabricated. | |||
Steel is much more malleable than aluminum, and it has a wider spread between yield strength and ultimate | |||
tensile strength. | |||
The key distinct advantage of steel over aluminum is, it is less prone to cracking. | |||
The steel track shoes used have a typical tensile strength of 69,600 psi (480 MPa) and yield strength of 40,600 | |||
psi (280 MPa). | |||
Competitors who used 6061-T6 aluminum track shoe have a typical tensile strength of about 42,000 psi (290 | |||
MPa) and yield strength of about 35,000 psi (241 MPa). | |||
The track shoe is reinforced box design, enhancing the floating capability. | |||
A large adjacent surface area translates to enhance traction on soft terrain, and higher efficiency when | |||
“paddling” in water. | |||
Modular Design | |||
Both the assembly and disassembly processes can be achieved in under 3 hours if equipped with proper | |||
tools and crane. | |||
No special tooling is required for the assembly and disassembly process. | |||
Designed to be easily transported by low bed trailer. | |||
Undercarriage modules and attachments are designed to be able to fit into 40 ft container. | |||
