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.
