Crain Tri-Max® Standard Dual-Clamp Tripod Zoom


The Tri-Max® by Crain is, without a doubt, the best instrument tripod on the market today. It’s the only surveying-grade tripod with certified accuracy – highly recommended for all servo-driven and robotic total stations and 3-D laser scanners. This tripod easily meets the ISO 12858-2-H standard for the stability of instrument tripods. The revolutionary design of this tripod series and Crain’s commitment to quality mean this tripod will meet the ISO standard right out of the box, and after years of field use.

Performance data for the Crain Tri-Max tripod: Tripod Torsional Rigidity Data Analysis by Dr. Craig G. Downing, Southeast Missouri State University.

The Tri-Max features a 6-5/8" head with large center hole (2-5/8") to facilitate an easy set-up over a point. A retaining system, which prevents leg kick-out and accidental falls on slick surfaces, is stored on the inside of the leg and can be left in place when the tripod is not in use.

The Tri-Max features an advanced foot design. The large "footbed" is there to facilitate solid planting for stability. The shape and size of the foot are designed to allow for a solid placement on any terrain. The foot is equipped with a replaceable point and a retention loop for use with a safety strap.

This Tri-Max version features a positive-locking dual clamp set-up, which uses both styles of clamp on each leg for added security. All Tri-Max tripods feature locks that can be reversed to the inside of the leg if desired. The Tri-Max tripod will hold a maximum of 65 pounds (30 kg). It expands to 71 inches (180.34 cm) and contracts to 44 inches (111.76 cm). Comes with Crain’s 5-year warranty.

Great, Sturdy Tripod for Heavier Equipment Review by Michael L.
We use this tripod mostly for a heavy, old Leica scanner that we use from time to time. We also like to use this tripod for an older Leica TCA1800 total station. The dual-clamp is great because you have the quick release levers for fast, short set ups and the traditional wing nut style lock for added security and stability when using equipment over a point for longer periods of time or using heavier equipment such as scanners.
