SECO 90553 Tri-Max Standard Dual Clamp Instrument Tripod

Overview

The SECO 90553 Tri-Max Standard Dual Clamp Instrument Tripod is a surveying-grade fiberglass tripod built for robotic and servo-driven total stations, 3D laser scanners, construction lasers, and other precision instruments.

The Tri-Max design meets the ISO 12858-2-H standard out of the box and is engineered to maintain dependable stability after years of field use. Its fiberglass legs, dual-clamp locking system, broad footbeds, and integrated leg-retaining system provide a secure platform for demanding surveying, scanning, monitoring, and construction applications.

A 6-5/8-inch flat head with a large 2-5/8-inch center opening simplifies instrument mounting and setup over a survey point. The tripod supports equipment weighing up to 65 lb, extends to 71 inches, and collapses to 44.5 inches for transportation and storage.

Surveying-Grade Stability

The SECO Tri-Max is designed for precision equipment that requires a stable and dependable mounting platform.

Small movements in a tripod can affect angular measurements, point-cloud registration, laser alignment, layout accuracy, and monitoring results. The rigid Tri-Max construction helps reduce movement under demanding field conditions.

It is particularly well suited for:

• Robotic total stations
• Servo-driven total stations
• 3D laser scanners
• Construction lasers
• Precision optical instruments
• Heavy surveying equipment

ISO 12858-2-H Performance

The SECO 90553 is designed to meet the ISO 12858-2-H standard directly out of the box and continue providing stable performance after extended field use.

This standard addresses performance requirements for surveying instrument tripods. A stable tripod helps minimize instrument movement caused by vibration, leg deflection, uneven terrain, and changing field conditions.

Dual-Clamp Leg Locks

The SECO 90553 features a dual-clamp locking system for securing the adjustable tripod legs.

The dual-clamp design provides a secure hold after the desired height and position have been established. Each leg adjusts independently, allowing the tripod to be leveled and stabilized on uneven or sloped terrain.

All clamps should be checked before mounting an instrument and periodically inspected during long-term setups.

65 lb Equipment Capacity

The Tri-Max supports equipment weighing up to:

• 65 lb
• 30 kg

This capacity allows the tripod to support heavier surveying and scanning equipment that may exceed the practical limits of lighter general-purpose tripods.

The instrument should always be centered, properly secured, and installed only after the tripod legs are firmly planted.

6-5/8-Inch Flat Head

The tripod features a broad 6-5/8-inch flat head for mounting compatible surveying, scanning, and construction instruments.

The flat mounting surface provides a stable base for equipment fitted with an appropriate tribrach, base, or threaded mounting connection.

Large Center Opening

A 2-5/8-inch center opening provides additional visibility and adjustment room when positioning the tripod over a survey point.

The larger opening makes it easier to view a nail, monument, control point, or other reference through the instrument’s optical or laser plummet during setup.

Fiberglass Leg Construction

The SECO 90553 uses fiberglass legs for rigidity, durability, and dependable field performance.

Fiberglass construction is well suited for precision instrument support and offers different thermal and electrical properties than traditional metal tripod legs.

Proper safety procedures must still be followed around overhead power lines, energized equipment, and other electrical hazards.

Integrated Leg-Retaining System

A built-in retaining system helps prevent the tripod legs from kicking outward on smooth or slick surfaces.

The retaining components are stored inside the legs and can remain installed when the tripod is collapsed. This keeps the system organized and ready for use without requiring a separate loose accessory.

The retaining system adds stability but does not replace proper tripod setup, inspection, or supervision.

Large Footbeds

Each tripod foot includes a large footbed that provides room for applying downward pressure and planting the tripod firmly.

The shape and size of the feet are designed to support stable placement across a variety of surfaces, including:

• Soil
• Gravel
• Compacted construction areas
• Pavement
• Uneven ground
• Sloped terrain

All three feet should be securely positioned before equipment is mounted.

Replaceable Points and Safety-Strap Loops

Each tripod foot is equipped with a replaceable point, allowing worn ground-contact components to be serviced without replacing the complete leg assembly.

Retention loops are also provided for use with a compatible safety strap. A safety strap can provide additional security around traffic, vibration, smooth surfaces, or active construction equipment.

Safety straps are sold separately unless otherwise specified.

Adjustable Working Height

The SECO 90553 provides the following specified dimensions:

• Extended height: 71 in (1.8 m)
• Collapsed length: 44.5 in (113 cm)

The independently adjustable legs allow the tripod head to be positioned for different operators, instruments, terrain conditions, and line-of-sight requirements.

Ideal Applications

• Robotic total station surveying
• Servo-driven total station operation
• 3D laser scanning
• Construction laser setup
• Precision construction layout
