What is a Water Ballast Tank for Truss Systems?
A water ballast tank is a portable counterweight system used to stabilize truss structures by adding weight at the base. It is commonly used in outdoor stage, lighting and roof truss systems where additional anchoring is required.
System Overview
This 1×1×1m PVC ballast tank provides up to 1 ton of weight when filled with water, and is designed for:
It is an essential safety component, not just an accessory.

Why Use Water Ballast Instead of Steel Weight
1. Easy Transportation
empty → lightweight
filled on-site → heavy
2. Flexible Weight Control
3. Cost Efficiency
lower transport cost
reusable system

Engineering Insight
Wind Load is the Real Risk
Outdoor truss systems are affected by:
wind pressure
lateral forces
uneven load
Ballast is required to counteract these forces.
Stability = Weight + Base Area
System stability depends on:
ballast weight
base plate size
structure height

Ground Support vs Anchoring
Ballast tanks are used when:
Safety Requirement (VERY IMPORTANT)
Incorrect ballast leads to:
structure tipping
collapse risk
serious safety hazards
→ Safety Standards & Engineering Constraints
Integration with Truss System
Ballast must match:
truss height
load capacity
structural type
→ Connection & Material System
