Inc. provides engineered and manufacturing solutions
for unique applications pertaining to lifting,
securing and mobilizing of containers and other items.
Over the years, we have designed thousands of products.
Our roots date back to the 1950's,
shipping world began using the newly developed cargo
container to carry cargo around the world. The intermodal
industry was born and we designed all kinds of tie downs and
lifters specifically for cargo containers. Our understanding
of "the container" soon led to servicing the needs of the
unique uses of these containers, which remains one of our
primary areas of focus today. The worldwide standardization
of the container gave birth to other uses of the container,
uses such as communication shelters, waste containment and
transport containers, living shelters, special storage
modules, modular construction, and more.
Many special uses were driven by the military; we
provide special lifters, tiedowns and mobilizing products to
support these applications. Our ability to understand an
application, engineer a solution and manufacture it in short
order, has resulted in TANDEMLOC becoming the choice of many
major defense contractors. Most recently, we designed,
manufactured and delivered most of the tiedowns used on the
new "Medium Tactical Vehicle" (MTVR), now being used
by the United States Marine Corps.
Our problem-solving background in the container lifting
business enabled us to service another market, "Below the
Hook Lifters". Over the years, we
have developed a huge selection of general-purpose spreader
bars, lifting beams and frames of all shapes and sizes. We
also design and build special purpose, proprietary lifters.
The products shown online represent a partial selection
of lifters - available as shown or "tweaked" to meet your
specific needs. We can also design items 'from the ground
With most applications, we are able to design,
manufacture, test and ship the lifter within a few weeks of
We build lifters to ANSI/ASME
B30.20. And, we proof-test every
lifter we build.

TANDEMLOC'S "PROOF TESTED" CHAIRMAN
of the BOARD: We've been
fortunate over the last many years
to develop a great crew of people.
John "MIKE" DiMartino, Sr.
was the first and foremost employee TANDEMLOC, INC.
A great many souls owe their
livelihood to the hard work and
dedication of this gentleman's life
work. We can't say enough good
things about the man...really. His
in-depth knowledge of the ANSI /
ASME, ISO and MIL STD specifications
to which we manufacture, has been a
prime mover in TANDEMLOC's growth
since our inception in the early
1980's. His experience goes back to
the late 1950's and, at one time, he
sat on the board of ISO standards.
He was personally responsible for
many patents. Sadly, Mike passed
away in 2008 after many, many years
of working every day at Tandemloc
with his two sons -
John Jr., President and Bill
DiMartino, Vice-President, who have
kept the TANDEMLOC ship on
the course he chartered.
terrific product line is our Casters. We offer a line of
"Container Casters" which connect to ISO containers or
shelters for short distance movements, such as those
required in-plant or around the field. They are available in
a variety of capacities and wheel types, up to handling a
fully loaded 40' container. We also provide casters for
general industry, focusing primarily on very heavy
applications. For example, we have developed a low height,
10,000 lb and 15,000 lb capacity pneumatic caster. We often
supply casters with capacities of 20,000 lbs or more. We can
also design and build heavy dollies and carts.
We hope you will find our website helpful in your
selection of products and we invite your inquiry.
