DESCRIPTION
The Mega Portable Tank (MPT) is a 12,000 gallon
platform or stand tank designed for towing with a
fifth-wheel on-highway tractor. The Mega MPT is
used to rapidly fill water distribution equipment to
maximize productivity. All Mega MPTs are self-
erecting by use of an engine-driven hydraulic pump
and hoist cylinders with pin locks. Mega MPTs have a
10 inch diameter discharge pipe capable of filling a
5,000 gallon tank in approximately 2 minutes. The
MPT can be filled from a municipal water source or
with other water pumping equipment. The 3” fill pipe
is equipped with an automatic shut off to prevent
overfilling.
The MPT is designed to comply with all Department
of Transportation requirements, and is available in
custom colors and with special signage as specified
by the customer. For more information, please
contact the Mega Sales Department at 1-800-345-
8889, or contact your local dealer.
MPT TANK
The MPT tank is 2.59m (8.5 ft) in diameter, 11.13m
(36.5 ft.) in length, and has a capacity of 45.42 L
(12,000 gallons). The corners of the tank are
reinforced to provide sturdy connection to supports.
An access ladder leading to the top of the tank is
located at the rear of the trailer, and a ladder is
located inside of the tank. An 8” diameter float is
located inside of the tank for automatic fill shut-off
when the tank is full.
SELF-RAISING SYSTEM
The MPT’s self-raising system incorporates dual
hydraulic cylinders and a 6.5 horsepower engine with
a hydraulic pump.
HYDRAULIC CYLINDERS
Dual 127mm (5 inch) diameter double-acting
hydraulic cylinders that allow the tank to be raised for
connection to a tractor. The frame can be lifted with
the same cylinders after tractor hook-up is complete.

DISCONNECT (IF EQUIPPED)
If the valve fails to operate, a release mechanism can
be activated by using the pin installation tool to pull
the release cable. This will release the pin for the
actuator to disengage it from the butterfly valve.
If multiple systems are in close proximity to one
another (less than 100 yards or 92 meters), it may be
possible to operate more then one unit
simultaneously. This may cause unexpected opening
of the butterfly valve releasing water from the tower.
Ensure there is enough distance between the
systems, and all personnel are clear from underneath
tanks. Test to ensure only the desired tank valve
opens when signaled.
