Amphibious Excavator

An amphibious 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. Amphibious excavators 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).

Product design are accomplished by utilizing latest CAD software, simulated via advance Finite Element Analysis (FEA) tools, ensuring optimum design integrity.

All EIK Engineering products are  certified.

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.


The highest quality Pontoons:

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. It has 3 water tight compartments hermetically sealed with individual manhole for easy access from outside for inspection and preventive maintenance.


Supplementary Pontoons and Spuds:

The primary pontoons are designed with future-proof in mind. 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 add-on the supplementary pontoons and spuds without tedious modification. A truely pulg-and-play system.

The supplementary pontoons can be easily attached onto the outer side of the primary pontoons to enhance stability. The hydraulic-meachnical 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.


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.


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 bushing that greatly prolongs the useful working life of the track chain.


Track Shoe:

Track cleats are steel fabricated and robortically welded to utmost precision. Steel material is favoured over aluminium alloy because of its malleable property. It has a much wider spread between yield strength and ultimate tensile strength. The distinct advantage of steel over aluminum is it is less prone to crack.

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.


Final Drives: 

Patent pending 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.


Attachements:

Standard configuration of the Amphibious Excavator comes with a long reach attachment unless otherwise stated. The convenience of an extended reach and greater working range is always a welcome advantage when carrying out work in marsh land and dredging related projects.
