Crain’s
revolutionary Tri-Max tripod, stands alone in meeting today’s
demanding stability requirements. In fact, tests have confirmed
that the Tri-Max, in many cases, is more than 100 times more
stable than conventional tripods, and retains this stability in
use, without frequent adjustments, in the face of commonly
encountered field conditions such as age, wind, fatigue,
contamination, wear, temperature, moisture, and humidity. What
is the direct result of the superior stability that exists in
the Tri-Max? Significant increases in realized accuracy
(closure) is not just possible, but common! Unparalled-no other
tripod even approaches the Tri-Max’s performance!
To
develop the Tri-Max, ultra-modern materials and processes were
combined. This next generation tripod was created using
computer aided modeling and analysis techniques. A unique hinge
spindle design permits leg rotation yet prevents lateral
movement. Legs are connected with a rigid adhesive that never
loosens regardless of age and environmental exposures. The
entire structure is designed to dampen vibration and resist
creep.
Composite extensible legs are formed in a continuous wedge
profile that allows more locking force to be developed by hand
clamping than conventional tripods develop with their locking
systems engaged. The Tri-Max is not only significantly better
than all other tripods; it actually creates a new standard for
tripod performance.
Advanced Designs
In addition to outstanding stability, the Tri-Max tripods are
loaded with other important and practical features.
Tri-Max tripods feature a large, round head that is precision
turned. The mounting hole is also large to aid plummeting.

Snap cap head cover (standard) attaches without screws and has
a retainer strap included.
Ergonomic designs include a wide carry strap (standard) with
shoulder pad and a carry handle (also standard), which is unique
to the Tri-Max and far more comfortable than hole-in-leg
handles.
Another Tri-Max exclusive feature is the open leg design, which
facilitates mounting of equipment bags, data collectors,
batteries, and many other accessories directly to the tripod’s
legs. Removal is not necessary when the tripod is collapsed and
stored. Additionally, convenient utility rings (standard), for
attaching accessories, are provided on the center leg caps and
on the tripod’s feet.
Retaining System

A popular feature, the kick out prevention system (standard) is
designed to prevent instrument falls on slick surfaces and from
persons tripping on a leg. The system stores on the inside of
the leg or can be left in place. This feature does not
interfere with plummeting or instrument person’s stance. One
“save” is all it takes!
Accessories
A number of accessories are available for the Tri-Max Series
tripods. They include leg bags, storage bags, retractable
points for finished floors, foot spikes, plates for unstable
terrain, and equipment attachment snap-rings.
Tri-Max Foot

The Tri-Max features a large foot bed to better facilitate solid
“planting” for stability. The shape of the foot is designed to
solidly engage terrain, is equipped with a replaceable steel
point, and is designed to accept a number of unique
accessories. A special applications attachment/retention loop
is provided on the rear of the foot.
The foot’s superior strength is clearly demonstrated when it is
driven into a log with a sledgehammer, without failure!
Locking Systems
Two new locking systems are available: Quick Clamp
(lever-cam) and Screw Clamp (knob-screw) styles. Both styles
are ergonomic, positive-locking, and field reversible to the
inside as shown. On tall models, an additional thumbscrew style
lock is also standard. A fixed-leg model (collapses for
shipping) is also available. Wedge profile legs can actually
lock by hand clamping! All Tri-Max locking systems are designed
to form a single unified rigid instrument platform system.
