Summary
- Military Products
 Amtech
is the original manufacturer of molded composite products,
known as Helmet Hardtops®,
which provide a permanent roof top solution for the HWWMV. Our shelters are
the only product of their kind,
tested by the military at Aberdeen Proving Grounds and are an authorized
replacement for canvas on various HMMWV variants. The Helmet Hardtop® is
unique in that it provides a single compartment (that is) shared by crew
and cargo, similar to a typical sport utility vehicle, and provides an
area protected from water, dust, and theft.
The Helmet Hardtop® is available in a multitude of configurations primarily
differentiated by number of personnel doors on the vehicle, height of the
shelter, and armor protection. In addition to a product line always available,
we offer custom solutions for unique requirements that Defense Contractors
may receive from the military.
• DLA CONTRACT: SP075002D9729
• DLA EMALL CONTRACT: SP073002DE003
(www.emall.dla.mil)
• Amtech is an ISO 9001:2008 Registered company
• Amtech is an
Equal Opportunity & Affirmative Action employer
We have an excellent DLA rating that covers a 10 year period of time, with
over 9,000 Helmet Hardtop® delivered, and reflects Amtech's commitment
to provide the United States military with the best product available
to meet their needs, and do so as required when required!
Within all Helmet Hardtops® will be found a data plate which provides model
number, serial number for that model, date of manufacture, and CAGE code.
Should questions ever arise regarding the item, the users' utilization
of that information will allow Amtech personnel to respond to queries
regarding that specific product.
Helmet Hardtops® are used in great numbers throughout all branches of the
Armed Forces. With over 9,000 Helmet Hardtops® in use, it is easy to understand
why troop units desire this versatile product!
Known functions include mobile command and control (TOCS) , maintenance
contact vehicles, communications, fire control, mobile dental clinics, electronic
attack, medical purposes including ambulances, and, when mounted with a
gun ring and weapon, convoy escort duty.
Helmet Hardtops® are manufactured as a homogeneous unit using high quality
composite materials. The product has a uniform radius with no seams or overlaps
for a long lasting and stress free structure. It is capable of withstanding
an ambient temperature of 160°F in storage or transit, and 120°F
plus solar load for normal operations. For weather protection our tops,
without the aid of supplementary sealing, caulking, taping, or other means,
are capable of withstanding a 40psi surface spray from 19 inches away. In
addition, Helmet Hardtops® are resistant to the effects of blowing sand
without damage and degradation.
Helmet Hardtops® are structurally robust and can withstand a (simulated)
snow load of 40 pounds per square foot (lb/ft2) and a personnel load of
660 pounds static over 2ft without sustaining any physical degradation.
The Helmet Hardtops® roof is impact resistant and can withstand a
blow from a 30.0 pound steel cylinder with hemispherical end dropped
from 30 inches above the surface without structural damage. During testing
at Aberdeen Test Center, static compression tests were carried out with
the objective of determining what force was necessary to cause the product
to buckle during swing lift operation. The Army ran the load up to 32,000
pounds of static pressure with no deformity or degradation of the product.
This was 5,000 pounds in excess of the test requirement.
