Aluminum pin-connected trusses are a mainstream type of Aluminum Truss focused on "quick assembly and disassembly." Their core feature is that they can be joined using pre-installed pins, positioning holes, and matching latches at the Truss ends—no bolts or welding required. With their two big perks—"modular design + easy to use"—they’ve long been the top pick for putting up frames at temporary events. Heavy-Duty Pin-Lock Truss Whether it’s a performance, exhibition, or celebration, you’ll find them being used everywhere. Working Principle
The key design of these trusses lies in their "connection joints," Aluminum Pin-Lock Truss and the entire structure consists of three main parts: 1. Main Frame
Made by welding 6061-T6 or 6082-T6 aluminum profiles (mostly square or circular tubes) into standard units with triangular or rectangular cross-sections (common lengths: 1m, 2m, 3m). "Pin-Lock Truss for Concert Rigs Connection plates" are welded to both ends of each truss section. 2. Pin Assembly
Each connection plate has 3–4 pre-installed spring-loaded pins (or manual pins) that align with the positioning holes on the connection plate of another truss section. During assembly, the pins are directly inserted into the holes to achieve initial fixation.
3. Safety Latches
Some models add "rotating locking tabs" or "clips" next to the pins. After inserting the pins, the locking tabs are rotated to secure them, preventing the pins from falling out due to vibration (e.g., from audio resonance at concerts).
In simple terms, Aluminum Alloy Pin-Type Truss the assembly logic is similar to "Lego bricks"—align the pins, insert, and lock. 1–2 people can connect one truss section in 30 seconds, with no tools needed.
Extremely High Assembly/Disassembly Efficiency, Saving Labor and Time
Compared to bolt-connected trusses Lightweight Aluminum Truss System (which require wrenches to tighten bolts one by one, taking 5–10 minutes per section), pin-connected trusses need no tools at all. A 2-person team can set up a 10m-span lighting truss in just 30–40 minutes. When disassembling, you only need to pull out the pins to take the trusses apart. They are especially suitable for temporary events that require "same-day setup and teardown," such as touring concerts and market stages.
Lightweight and Easy to Transport, Friendly to Venues
Made of aluminum alloy Durable Aluminum Pin Truss (weighing approximately 8–15kg per meter; for example, a 300×300mm model weighs about 10kg per meter), and with each section being no longer than 3m when disassembled, 2 people can easily carry them. No cranes or forklifts are required—even venues without heavy hoisting conditions (such as indoor exhibition halls and small theaters) can be set up easily, and there’s no risk of damaging the floor (e.g., marble floors in shopping malls).
High Fault Tolerance, Easy for Beginners to Operate
There’s no need for precise alignment of bolt holes during assembly; Pin-Lock Truss you just align the pins with the positioning holes and insert them. Even workers new to the task can master it after 10 minutes of simple training, reducing installation issues caused by operational errors (such as loose bolts or misaligned holes). Applicable Scenarios and Precautions
1. Most Suitable Scenarios
Temporary performance events: Industrial Aluminum Pin Truss Such as lighting trusses for bar resident singers, background trusses for small music festival stages, and temporary canopy trusses for outdoor celebrations—scenarios that require quick setup and frequent movement.
Exhibitions/trade shows: Background frames and product display frames for booths, which are set up 1–2 days before the event and disassembled immediately after, without occupying venue time.
Mobile events: Pin-Lock Truss System for Stages Such as stage trusses for touring exhibitions and rural performances. When disassembled, they can be transported in ordinary trucks and quickly reassembled at the new venue. 2. Scenarios to Avoid
Ultra-heavy loads: The rated load capacity of a single truss section is mostly 500–1500kg (for a 10m span). They are not suitable for hanging large line array speakers (over 300kg each) or LED screens larger than 10㎡, as excessive force on the pin joints may cause loosening.
Long-term fixed installation: Such as permanent lighting trusses in theaters and studios. Over long-term use, pins may shift slightly due to vibration, making them less stable than bolt-connected trusses and requiring frequent inspection and maintenance.
Outdoor scenarios with strong winds: Such as open-air large stages in coastal areas. Strong winds may cause lateral displacement between trusses, and the lateral resistance of pin joints is not as good as that of welded or bolted joints—additional diagonal braces and counterweights are required.
