Aluminum Top Section for 290x290mm Truss Tower Systems
 |
|
The truss tower top section is installed above the truss pillar. It works together with the hoist and sleeve block to guide the lifting path as the connected truss structure is raised or lowered.
The assembly combines a aluminum body, two 110×50mm pulleys and bolted hardware. The lower mounting section connects the assembly to the 290x290mm truss pillar. It is a functional part of tower systems for stage roofs, lighting grids and event truss structures. |

Product Features
Designed for 290mm Truss Pillars
The top section is designed for matching 290×290mm spigot truss pillars in ground support systems. Its four lower connection sleeves align with the pillar’s connection points for assembly at the top of the tower.
Supports Truss Tower Lifting
Installed at the top of truss pillars, the top section works with a compatible hoist and sleeve block to raise and lower connected truss beams. It forms part of the lifting arrangement used in ground-supported stage roof and lighting truss systems. The top section remains fixed while the sleeve block and connected beams travel along the truss pillars.
Lightweight Aluminum Construction
The aluminum body helps reduce handling weight, making the top section easier to transport and position during tower assembly. This is useful for rental equipment and temporary event structures that require repeated setup and dismantling. Aluminum’s natural oxide layer provides resistance to corrosion, helping protect the body during normal use and storage.
FAQ
Q: What does a truss tower top section do?
A: It forms the upper pulley assembly of a truss tower lifting system. It works with the hoist and sleeve block arrangement to guide the lifting path when raising or lowering connected truss beams.
Q: What is the difference between a top section and a sleeve block?
A: The top section stays at the top of the truss pillar and provides the upper pulley assembly. The sleeve block connects the truss beams to the pillar and moves along it during lifting and lowering. They work together as separate parts of the truss tower system.
Q: Will this top section fit my existing truss pillars?
A: This top section is designed for matching 290×290mm spigot truss pillars. Matching the nominal truss size alone does not confirm compatibility. The connector dimensions must also match. It is better to provide your pillar truss drawing or connector details for verification.
Moving heavy steel base plates is one of the most physically demanding parts of event rigging. Our six in one base plate dolly is designed to solve this problem by organizing and transporting up to six steel plates measuring 600 by 600 mm with an 8mm thickness. By storing these heavy plates vertically, this cart drastically allows stage crews to load, unload, and organize transport space with maximum efficiency.

The aluminum truss sleeve block connects truss beam to a truss pillar in a truss tower system. Internal guide rollers guide the sleeve along the tower as the connected truss is raised or lowered using a compatible lifting system. Available in silver and black versions, it provides a practical connection point for stage roof grids, lighting trusses and goalpost structures.
