Powering High Performance Amphibious Excavator






   Amphibious Excavator / Marsh Buggy


EIK is one only certified manufacturer by Caterpillar, Volvo and Hyundai for amphibious excavator (aka swamp excavator or floating excavator) for the global market. Thanks to our patented multi-synchronous direct drive' system, a pivotal technology developed by EIK that positions us at the forefront of amphibious excavator design. The paradigm shift in how modern amphibious machines are being designed has won the hearts of numerous customers, both new and experienced users in the industry. We are now the largest full range (7 models) amphibious excavator manufacturer by volume in South East Asia with worldwide recognition for our quality and superior performance.


Best of all, customers will be delighted to know that we have extended the warranty period for the polymer track cleat/shoe to 24 months or 2,400 hours which ever comes first.



A marsh excavator / marsh buggy is specifically designed to manoeuvre in marshy, swampy area and soft terrain, and it can also float on water as an added safety feature. It is completely self propelled and can virtually access all terrains, and yet requires minimum supporting transportation and hoisting equipment. When fitted with our long reach front offers an unparalleled package with unmatched productivity for your investment. Greater versatility can be easily attained when used in conjunction with the wide range of attachments we produce. We have in-house expertise in designing customized attachments to tackle unique challenges where traditional off- the-shelf solutions fail to deliver.


With our successful track records in designing and providing long reach attachment for numerous and unique dredging applications over the years, our customers can look upon us to provide a complete package to carry out tasks in challenging terrains with incredible efficiency and high ROI (Return On Investment).

Final Drives:


The proprietary multi-synchronous direct drive system provides superior tracking capability, making the machine virtually undeterred in any terrain. A similar concept applies to a full time 4x4 gear system of a land vehicle. Multiple active drive motors propelling each pontoon provide at least twice the tracking power and performance capacity compared to conventional single motor design. Multi-motors also offers the advantage of redundancy during unforeseen circumstances.

Many users do not realize that not all swampy areas are flat but undulating, and mud viscosity varies widely from area to area and country to country. One would fully appreciate the superior design of multi synchronous motor powered pontoons in the most challenging terrains.



Hydraulic Extendable Pontoons:


An optional design feature allows each pontoon to retract or extend outward hydraulically. A fully retracted pontoons with reduced footprint provides the added advantage and convenience of transporting the machine on trailer without dismantling into modules. A tremendous saving on logistical cost over time. Fully extended pontoons provides the extra stability when situation call for.


The hydraulic control is totally independent (non shared) from the existing hydraulic circuit. We have an upgrade kit where an auxiliary hydraulic function can be added with full control from the operator cabin. Click on the video for details.

Structural grade tensile plate is used for the fabrication of the pontoons. The goal is to construct a high strength and durable base structure without being overly heavy, hampering its efficiency. The pontoon is designed to be able to float on water as an added safety feature (click here to watch video). It has 3 water tight compartments hermetically sealed with individual manhole for easy access from outside for inspection and preventive maintenance

Amphibious excavators work in the harshest conditions you can imagine. Our ultimate goal is to extend the dependable service life of the amphibious undercarriage system. Pontoons are shot blasted to ensure that the surface is thoroughly clean and free from contaminants and rust. In addition, this process presents the steel with a surface texture that provides excellent adhesion of prime coat of paint.




Supplementary Pontoons and Spuds:


Supplementary pontoons can be easily attached onto the outer side of the primary pontoons to enhance stability. The hydraulic-mechanical spuds system which is control from the operator cabin  is a superb solutions to overcome buoyancy in deep water, providing additional stability and enhanced operability on water up to 4 meters deep.


Users can chose to add the supplementary pontoons and spuds system at the later stage when need arises. Auxiliary hydraulic lines are preinstalled on all primary pontoons whereby the user can simply installed without tedious modification. A truly pulg-and-play system and future proof in design.

Track Shoe:

The track shoes/cleats are steel fabricated and are robotically welded to utmost precision. Steel is favoured over aluminium alloy because of its malleable property. Its malleability makes it less prone to cracking, due to the wider spread between yield strength and ultimate tensile strength.

The steel track cleat used has a minimum yield strength and tensile strength of 280 Mpa (40,600 psi) and 480 Mpa (69,600 psi) respectively, which translates to approximately 16% and 65% improvement of yield strength and tensile strength respectively over 6061 T6 aluminium alloy.



Customer may opt for the polymer track shoes instead. The grade of polymer we have selected is extremely tough and yet appropriately flexible for its application. It can better retain its shape and is less susceptible to deformation than ferrous based or aluminium alloy.


We have designed a unique clamping system which is far more reliable than the direct bolt-secure system. Our engineering team has conducted extensive exercise and clocked enormous of hours on field testing, experimenting with various clamping system. And we finally have a superior solutions that will stand the test of time.


The polymer track shoe is fully backward compatible, customers who have invested in our pontoon undercarriage can be easily upgraded. Simple and hassle free.


Track Chain:

One of the most critical components of the undercarriage system, it is entirely in-house design and manufacture, to ensure proper quality control. One of the criterion of a good design is that the track chain has to perform reliably under various working conditions. Special grade steel is used and precisely trimmed to extremely tight tolerance. We insist that this is the only way to maintain the quality we demand and there should be no compromise under any circumstances.


Each roller has an embedded induction hardened bushing that greatly prolongs the useful working life of the track chain.

Axle and Sprocket:

We unequivocally favoured a non weld-on sprocket design. Sprockets are precisely machined and bolted onto the axial. This concept ensures a perfect alignment of each sprocket across the axial, a critical criterion for the longevity of the track chain.


The hardworking sprockets, rollers and bushings (embedded within the rollers) are made from hardened steel which helps in reducing the frequency of replacement and costly downtime. Rollers travel on a strip of wear resistant steel track, preventing it from premature wearing to the pontoons.

Can the Amphibious machine turn easily on dry ground?

Absolutely! Our patented multi-synchronous drive motor system is a leap forward from the conventional dual motor undercarriage design. Not only manoeuvre effectively on hard and dry terrain, it can powered the entire machine up a slope with tremendous ease. We have fundamentally changed the paradigm of the decades old design.
