芬蘭土方設備製造商REMU推出了新型Big Float E35浮動底盤系統，該系統可以將標準挖掘機改裝為兩棲挖掘機。
E35底盤可以與市場上大多數30-35噸的挖掘機組裝在一起，並具有更大的挖掘機所具有的所有優點：更大的動力、更長的工作範圍，每個鏟鬥負載的體積更大，因此生產率更高。
E35底盤的下部完全由耐磨鋼製成，可防止外部應力和衝擊。每個浮橋有五個水密部分，浮橋頂部設置了檢修孔。底盤形狀和尺寸經過精心設計，可以在各種工作環境中最大限度地提高其穩定性。 E35行走馬達與行星式終傳動配對，可通過驅動鏈輪直接向履帶鏈條傳遞高扭矩。

Big Float pontoon undercarriage turns standard excavators into amphibious excavators
REMU has launched new Big Float E35 pontoon undercarriage, which can transform a standard excavator into an amphibious excavator.
The E35 can be assembled with most 30-35 ton excavators available on the market and offers all the benefits that come with a larger excavator: more power, longer outreach, higher volume with each bucket load and therefore higher productivity.
The lower part of the E35 is entirely made of wear resistant steel for protection against external stress and impacts. Each pontoon has five watertight sections with manhole access placed on top of the pontoon. The carefully engineered shape and measurement of the undercarriage maximizes its stability in various job environments. E35 travel motors, paired with planetary final drives, deliver high torque through drive sprockets directly to track chains.
