Topcon 809550 Medium Duty Aluminum Elevating Tripod (44 to 93-inch)

Topcon 809550 Medium-Duty Aluminum Elevating Tripod

The Topcon 809550 is a professional-grade aluminum elevating tripod built for contractors, surveyors, and layout crews who need reliable instrument support across a wide range of working heights. Spanning 44 to 93 inches, this medium-duty tripod handles the demands of daily jobsite use while keeping your total-station, optical level, or laser instrument steady and on-target.

Overview & Jobsite Applications

Designed to work alongside Topcon and compatible third-party instruments, the 809550 excels in construction layout, land surveying, machine control setup, and interior laser leveling. The double-telescoping leg design combined with a crank-driven elevating center column gives operators fine height control without breaking down the entire setup — a critical advantage when terrain changes mid-task or ceiling height is a factor indoors.

Key Specifications

• Working height range: 44 – 93 inches
• Collapsed transport length: 48 inches
• Leg material: Aluminum
• Top plate thread: 5/8 x 11 (industry-standard)
• Leg design: Double-telescoping with quick-release flip levers
• Center column: Crank-operated elevating mechanism
• Duty rating: Medium duty
• Compatible instrument types: Total stations, automatic levels, rotary lasers, optical theodolites

Key Features

• Wide height range: 44 to 93 inches of working height covers grade-level setups through overhead applications without repositioning.
• Double-telescoping legs: Two-stage leg extension allows precise height increments and a compact carry length of 48 inches.
• Quick-release flip levers: Tool-free leg locking at each telescoping section keeps setup and breakdown fast in the field.
• Crank-operated center column: Smooth, controlled elevation of the instrument head without disturbing plumb or level.
• 5/8 x 11 threaded aluminum top plate: Mates with the vast majority of professional surveying and laser instruments without adapters.
• Aluminum construction: Provides a favorable strength-to-weight ratio for contractors who move between multiple setups daily.
• Pointed steel leg tips: Penetrate soft ground for firm anchoring on unimproved job sites.

Job Applications

Construction Layout: Set horizontal and vertical control points across a slab or structural grid. The wide height range accommodates grade-level backsights and elevated foresights in the same session.

Land Surveying & Boundary Work: Stable platform for total stations and optical theodolites where repeated pointings demand a tripod that won't creep or settle mid-observation.

Interior Laser Leveling: Position rotary lasers at finished floor or drop-ceiling height. The elevating column lets you fine-tune beam elevation after the instrument is leveled.

Machine Control & Grade Checking: Mount GPS rovers or slope sensors at a consistent height over a control point while the crew works around the instrument.

Compatible Accessories

• Topcon 5/8 x 11 Tribrach Adapter — connect tribrachs and forced-centering accessories to the standard top plate.
• Topcon Wooden Tripod (Heavy Duty) — alternative for extreme vibration environments where aluminum dampening is insufficient.
• Universal Tripod Bag / Carry Case — padded transport protection for the 48-inch collapsed tripod.
• Topcon AT-B Series Automatic Level — pairs directly with the 5/8 x 11 top plate for differential leveling runs.

Frequently Asked Questions

What thread size is the Topcon 809550 top plate?

The top plate uses a 5/8 x 11 thread — the industry-standard for surveying and construction instruments. Most total stations, automatic levels, and rotary lasers mount directly without an adapter.

Can I use the 809550 with instruments other than Topcon?

Yes. The 5/8 x 11 threaded top plate is compatible with instruments from Leica, Trimble, Spectra Precision, Sokkia, and other major manufacturers that use the standard thread size.

What is the maximum working height of the 809550?

The elevating tripod reaches a maximum working height of 93 inches with the legs fully extended and the center column raised. The minimum working height is 44 inches.

How does the elevating center column differ from a standard fixed-head tripod?

A standard tripod requires you to adjust leg length to change instrument height, which can disturb your level and plumb setup. The 809550's crank-operated center column lets you raise or lower the instrument head a few inches after leveling — saving time and reducing re-leveling cycles on the job.
