Titan
Bridge
Lifting System
MAMMOET’s Titan Bridge Lift system was designed and developed as a
response to the high demand in bridge maintenance and construction in
short periods of time. It is specially designed to install large
pre-manufactured bridge spans, remove old bridges, or readjust existing
bridges by moving a bridge vertically or horizontally. The system is
essentially two systems fit in one: a moving system, namely the
Self-Propelled Modular Transporters, and a heavy-lifting system, namely
the Ttan system.
The SPMTs are computer controlled vehicles used to move
and lift components or the petrochemical, offshore, power, and heavy civil
markets including bridges. A replacement bridge can be built near its
final location and then moved to its final location in hours with SPMTs.
This allows construction of the new bridge in a location that does not
impact the traveling public, and on a timeline that allows attention to
detail to achieve long-term performance.
The system uses existing lifting equipment with the
SPMTs to create an integrated system that can move and lift bridges in the
same motion. In this system the SPMTs are loaded with modular steel
“stools” ranging in height from 16" to 4' per stool. The hydraulic
suspension of the SPMT provides the lifting force for the Titan tower and
the stools are lifted incrementally and new stools are inserted after each
lift. This process is repeated until the bridge has reached its proper
height and then the SPMT moves the entire structure into place.

Asphalt Zipper Attachments
The Asphalt Zipper is a small size asphalt pavement milling
attachment that attaches to a front end loader bucket and grinds up
asphalt pavement. It can save 70% of the cost and time of using the older
technologies of saw cutting, chunking, and hauling asphalt. The Zipper can
remove pavements at up to 4,000 square feet per hour, cutting widths up to
48 inches wide in up to 12 inches of asphalt. It pulverizes the pavement
and leaves behind a drivable base that can be compacted to provide a new
top quality road base. The Zipper has been used by many underground
contractors, road and street contractors, and pavement demolition and
reclamation, cutting costs and time while eliminating asphalt materials
from the landfills and reusing them directly into the project.

Contractor Wastewater Filtration
WetSep is a patented in-situ filtration system designed to extract
dissolved and suspended solids from construction and factory wastewater.
Water that has been treated by WetSep meets the environmental
requirements, expressed as effluent discharge limits, of several
countries, including the United States of America, Singapore, Hong Kong,
Thailand, Japan and France. As a result, the treated water can be re-used,
directly discharged into the urban storm water system, or, discharged into
a natural body of water, such as a river, lake, or ocean.
WetSep was invented in 1998 primarily to treat
construction and industrial wastewater. However, its simple, flexible
design concept has allowed it to evolve, through the incorporation of
different water treatment technologies, into more specialized models for
limited, specific applications. For example, in 2003 a solar powered model
of WetSep that uses bio-degradable additives was developed to provide
potable water in developing countries and remote regions.

Pipeline Leak Noise Correlator
Cross correlation of leaks in water pipes works by placing sensors on
valves or fire hydrants and passively listening to the sound a leak
generates in the pipe. The time delay between when the signal reaches the
two sensor locations pinpoints the leak location.
The Leakfinder system was specifically designed to work
on PVC and plastic pipes. The correlation process works well on metal
water pipes because the leak noise is transmitted by the water hammer
mode.. However, PVC damps water hammer, and this damping must be overcome
for leak detection.
The two major advancements in Leakfinder are signal
processing and sensor development. The Leakfinder algorithm is optimized
for the low level and low frequency pressure waves associated with PVC
leaks. The advances also make correlations on metallic pipe more accurate,
making correlation of ‘quieter’ leaks possible. Secondly, transducers were
developed having extraordinarily low noise and frequency response at the
low frequencies associated with PVC and large diameter leak pressure
waves.
