River Dredging Equipment
The hydraulic undercarriage pontoons are extremely important to an amphibious excavator, Sinoway is pride of his abundant experience on manufacturing pontoons that last. According to your application requirement and working conditions, we areable to design and produce an amphibious excavator specially for your working area covering swamps, salty land, off-shore, river area and so forth.
Sinoway is able to offer hydraulic undercarriage pontoon to match your own excavator no matter they are Cat, Komatsu, Hitachi, Doosan, JCB, Volvo or any other brand excavator. All we need is the weight of the upper excavator and serveral connecting figures.
Main Features
High grade steel material for pontoons
Sinoway pontoons are standard made with alloy steel sheets,which is with high tensile strength and good corrosion resistant. For special applications like off-shore or salty areas, full weathering steel pontoons are also available as optional.For those applications require extra anti-corrosion, Sinoway offer hydraulic undercarriage pontoons with marine grade ship plate steel and with epoxy coating
Reliable structure for durability and easy maintenance
Each pontoon is with three independent compartments, hermetically sealed. Two or three chains on each pontoon. Dual-layer bottom plate structure ensure the pontoon for a much longer service life, marine coating is also available as optional.
Wear-proof Steel Track Cleats
Heavy duty marsh buggy track chains are constructed with high strength tensile steel, the bushings and pins are stronger, each pontoon comes with two or three heavy duty track chains, track cleats are fixed on the chain pitch welded or bolted. The hardened track chain rollers run in pontoon channels with a strip of wear resistant steel. The drive and idler sprockets are flame hardened to match the hardness of the track chain rollers.
Amphibious Modular Design
Designed to be easily transported by low bed trailer. Amphibious modules and attachments are designed to be able to fit into 40ft container. 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.
Supplementary Pontoons and Spuds (As optional)
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.
