Installing a Truss and Platform System - A Brief Overview

This month, we are sharing our quick step-by-step guide to installing a truss and platform system
dock. If you don’t have time to read the whole thing just yet, here’s a quick summary of the essentials: 

1. Understanding Alumi-Span Trusses

Alumi-Span offers pre-assembled trusses in standard lengths from 8' to 20'. Trusses have to horizontal poles with built in diagonal bracing, so there is no need for blind legs under the dock.  All adjustment can be made from the corners.  

There are two types of trusses:

• Regular Trusses – Feature a pole at each end.
• 90-Degree Trusses – Have one pole and clamps rotated 90 degrees for attachment to cross-arms to run a platform 90-degrees or perpendicular to an outgoing dock.

2. Key Installation Steps (Fast and Simple!)

A. Positioning the Truss Correctly

• Ensure the center casting (#310A) is on top with the “V” shape pointing upward for maximum strength.
• Use large bottom plates to simplify installation and stabilize the trusses.

B. Assembling the Dock Platform

• Bring sections out one at time and place on truss.
• Securely bolt deck sections together for a firm fit.
• Use black plastic platform connectors for added stability.

C. Properly Placing Stringer Brackets

• Position stringer brackets correctly to prevent trusses from sticking out beyond the dock sections.

D. Securing the Trusses

• Firmly clamp both upper and lower truss clamps before applying weight.
• To adjust the height, loosen and re-secure both clamps as needed.
• To raise center, leave top clamp tight, loosen and raise only bottom clamp

Intro to Uprights

When you build a boat dock, how do you use uprights?

Uprights, or dock posts, provide vertical stability and anchor the dock to the lakebed. Their functions include:

1. Height Adjustment. Uprights allow docks to be leveled according to water depth and seasonal changes. Docks with adjustable legs simplify installation and removal.
2. Foundation Anchoring. Depending on the lakebed conditions, uprights may use bottom plates, augers, or other stabilizing bases to remain secure. Alumi-Span’s permanent augers and Big Foot systems ensure stability even in soft or mucky lakebeds.
3. Load-Bearing. Uprights support the entire dock, including the dock platform itself, accessories, and any weight applied during use.

Intro to Crossarms

When you build a boat dock, how do you use crossarms?

Crossarms serve as horizontal support beams that span between upright dock posts. They are essential for:

1. Distributing Weight Evenly. Crossarms connect the uprights and help distribute the dock's weight. This ensures stability, especially under heavy weight.
2. Structural Integrity. By linking the uprights, crossarms reduce lateral (side-to-side) movement caused by water currents or wind.
3. Customization. Crossarms make it easier to build custom docks, allowing configurations like straight piers, "L"-shaped docks, or even platforms. For example, Alumi-Span offers crossarms in various sizes to match different dock designs and applications.
