芬兰土方设备制造商REMU推出了新型Big Float E35浮动底盘系统，该系统可以将标准挖掘机改装为两栖挖掘机。

E35底盘可以与市场上大多数30-35吨的挖掘机组装在一起，并具有更大的挖掘机所具有的所有优点：更大的动力、更长的工作范围，每个铲斗负载的体积更大，因此生产率更高。

E35底盘的下部完全由耐磨钢制成，可防止外部应力和冲击。每个浮桥有五个水密部分，浮桥顶部设置了检修孔。底盘形状和尺寸经过精心设计，可以在各种工作环境中最大限度地提高其稳定性。 E35行走马达与行星式终传动配对，可通过驱动链轮直接向履带链条传递高扭矩。

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.
