Amphibious Undercarriage for 20-22 ton Class Excavators

• 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 :

ï± Dredging
ï± Landscaping
ï± Erosion control and prevention
ï± Deepening of waterways and river deltas
ï± Maintenance and cleaning of rivers, lakes, shorelines, ponds, etc

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 4x4 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.
	Optional features for 20 ton class and above.
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 40ft container.
