REMU BIG FLOAT
Your access to unreachable locations
REMU Big Float is a unique amphibious excavator designed to work in most challenging
environments. It can be driven on solid land, through shoreline and to shallow water areas that
cannot be reach by normal excavator or by boat. As it’s totally floating, it’s also able to move on
swamp where it is impossible for a man to walk.
Big Float is designed and developed in Finland where thousands of lakes and peat swamps has
offered enough challenges and possibilities to test different working methods. When seeing
practical problems, and even traditional excavators sinking to swamp, we have realized the need for
safe and productive working method.

UPPER STRUCTURE
As a customer you are free
to choose any widely known
excavator brand to be mounted.
Once you decide which brand
excavator you want, REMU’s
team will do the rest, to deliver
a 100% ready to operate
amphibious excavator.
PONTOON UNDERCARRIAGE
Pontoons are manufactured in
three sizes. Each excavator to be
mounted, is carefully weighted
and measured to assure the
needed stability and buoyancy
from pontoons. Pontoons are
also available without upper
structure.

PONTOON UNDERCARRIAGE
Reliability comes with carefully
engineered details
Big Float undercarriage is built to survive trough changing terrains. Shape of the pontoon together
with powerful drive motors are designed to give best mobility in the worst surroundings. Strong and
proven chain structure is the same as in a normal excavator, offering reliable performance.
Big Float pontoon undercarriage is a unique platform that creates a safe working environment in
otherwise unsafe locations. Each part of the pontoon is a result of careful study. Abrasion resistant
steel is used in every parts of the pontoons that receive most shocks caused by uneven surfaces.
Furthermore, each pontoon is divided in baffle sections, to secure floating.
WHY TO CHOOSE
REMU BIG FLOAT?
•Better outreach compared to working from barge
•Tracks and chains same as in any normal excavator, strong, and proven quality.
•Pontoon structure with baffle sections guarantee safe floating
•Patented Technology EP 1727687 and US Pat. 7,588,106
Patented narrowed pontoon undercarriage structure.
Hydraulically adjusted
For an easy mobility and
transportation in public roads.
Durable Track System
REMU Big Float pontoons can be
hydraulically adjusted. This feature
allows the operator to pull the
pontoons together when passing
through narrow gaps and then spread
them apart to achieve a steady
position for operations.
Ground Pressure
less than 110 g/cm2
Two speed track drive
The driving power of Big Float comes
from standard excavator planetary gear
motors with massive maximum torque
of 56 kNm per motor. High speed mode
for easy terrain.

REMU BIG FLOAT
Built to operate in every situation
Digging dredging and Suction dredging
All kind of digging dredging in shallow water
areas down to 9 meters can be done with Big
Float. Removing mud or stones, transforming
reservoir banks or cleaning industrial waste
ponds are the most common applications for
Big Float. Big Float can also operate as a tool
carrier for suction dredging equipment.
Building Filtering Dam to a Peat Swamp
When swamp is used for peat production,
humus may leach as a result of drainage or
peat extracting. Big Float has been used for
building a dam to filter humus out of water
before it streams into the surrounding water
system.

Dredging Intake Channels and Reservoir in Hydro
Power Plant
Sediment that is piling on the bottom of the
intake channels and reservoir of barrage of
hydro power plant, can be dredged with Big
Float to maintain sufficient flow for the plant’s
operations.
Cleaning Channels
Big Float is easy to operate also in channels and
other narrow water ways. Trashes, leaves and
branches from the trees and excess sediment
that is piling on the bottom of the channel can
be removed with rake or dredging bucket.
Cutting Aquatic Vegetation
Aquatic vegetation that is growing on the
bottom of the river or lake can be removed with
Big Float and rake. With Big Float it is possible
to remove also roots of the plant and thus
prevent plants growing back. If it is needed also
special hydraulic tools can be used for cutting.
Mining Industry
Big Float can be helpful in many stages in open
cast mines. It has been used for example to
assist water pumps and other dewatering and
damming jobs.
Cutting Bushes from Water Side
Willow trees and other bushes can grow fast
and hide the landscape at waterside. With Big
Float and a special cutting tool, harvesting can
be done fast without leaving excessive marks to
the environment.
Landscaping
REMU Big Float can be used for landscaping in
swampy areas near river ways and shorelines
where conventional machine won’t be able to
operate as it can easily slip & sink into the soft
ground and get immobilized.

TRANSPORTATION AND HIGH MOBILITY
Makes remu big float the right
machine.
REMU Big Float is easy to transport from one job site to another: Simply retract the pontoons to
transportation width (3 meters), and drive the Big Float onto the lowboy. Even the biggest Big Float
model is only 3,5 meters width in transportation mode.

REMU’s patented pontoon undercarriage can be narrowed effortlessly in order to enable easy
transportation along public roads. Further REMU Big Float is instantly ready to use without any crane
or assembly work at the job site.
