OV Truss Tower
Ground Support Tower
The OV Tower is an innovative ground support system that incorporates the latest safety features. Designed to be compact and efficient, it is ideally suited for light to medium truss systems on tour. This system offers unparalleled versatility and convenience, making it a top choice for event organizers and technicians. The system has complete compatibility with the OV30 and OV40 range of products.
Integrations.
- Ground Supports Structures: Using both OV30, OV40 and OV40-CB as the grid truss with OV30 as the mast.
- Outdoor Roof Systems: Used as part of a festival roof, or similar giving light weight, quick to install solutions for those small to medium events.
- Video Screen Structures; Can be used as the main mast sections for for lighter weight TSG format video screen structures.

Components of an OV Truss Tower System
A self-climbing system is comprised of several key components that ensure both functionality and safety. Here’s a detailed breakdown:
- Mast: This is the primary structural element, providing the framework for the system, in this case OV30 Square.
- Hinge Elements: These components are essential for mast erection, allowing the structure to be raised and lowered safely.
- Aluminium Base with Adjustable Feet: This base ensures a secure and stable foundation, preventing unwanted movement. The outrigger legs stay attached but fold up to it can be transported, along with the hinge, as one unit.
- Sleeve Block: Facilitates the connection of the grid aluminium truss to the tower system and allows for free movement vertically during the lift operation. The OV Tower sleeve facilitates the use of OV30 and OV40 trusses as the grid.
- Head Block with Pulleys: Essential for the operational mechanics of the tower, enabling smooth movement and functionality.
The OV Truss Tower is the cutting edge of ground support self climbing systems incorporating all the safety features learnt of the last 4 decades from the original Slick Mini Beam Rigging Tower

- OV30 Tower Hinge; OV30-THP
Features include:-
- Dedicated Hinge unit for the tower.
-
- Tower Lifting Frame; OVTLF
Allows for the safe erection of the mast using a motor to control both lift and descent, eliminating the need for working at height. TSG Tower Lifting Frame
You also have the peace of mind that the loading charts have been calculated to EN17115 in order to give you the peace of mind that your lighting truss is still fit for purpose even after a few scratches and dents. What is the Frequent Use Factor?
Applications
Whether it’s setting up for a bustling marketplace event, a dynamic festival, or a cutting-edge industrial project, the adaptable nature of this tower system allows for seamless integration into any setting. The OV Tower’s ability to be quickly erected and accurately positioned makes it ideal for scenarios where time and precision are crucial.
Moreover, the system’s design allows for all technical equipment to be installed at ground level, which is then easily lifted to the desired height with a motor or hand hoist—streamlining operations and ensuring a safe working environment. The comprehensive redesign not only meets but exceeds modern safety standards, making it a reliable choice for any large-scale or intricate setup.
