Stage truss and rigging installation in Bay Area venue

AV & Stage Integration

Everything overhead is a safety decision.

YKCA designs, installs, and powers load-rated rigging systems for Bay Area venues — truss grids, motorized hoists, and structural attachment engineered for the loads they carry, by a licensed C-10 contractor.

Why Rigging Is Different

If it hangs over people, it needs to be engineered.

A lighting fixture on a floor stand is a nuisance when it falls. The same fixture suspended twenty feet above an audience is a life-safety issue. That distinction defines how YKCA approaches every rigging project: load assessment before hardware, structural review before attachment, and documentation before anything goes in the air.

As a licensed C-10 contractor, YKCA handles the full overhead system — the mechanical structure, the motorized hoists, and the branch-circuit power that feeds them — under one accountable team. No handoff between an AV firm and a separate electrician for the motor circuits.

What We Deliver

Six capabilities, one rigging team.

Truss Systems & Grids

Modular and custom truss grids, box trusses, and pipe-and-base systems sized for your venue and load requirements.

Motorized Hoists & Chain Motors

Variable-speed chain hoists with load-rated rigging hardware, controlled from a single console or integrated into your show-control system.

Fixed & Portable Structures

Permanent overhead steel grids and portable ground-support systems for venues that need flexibility between configurations.

Rigging Points & Structural Attachment

Engineered attachment to existing steel, concrete, or wood structure — assessed, load-rated, and documented before any hardware goes up.

Load Assessment & Engineering

Full load calculation for every project. Licensed structural engineering review and stamp where required by the authority having jurisdiction.

Inspection & Maintenance

Annual and as-needed inspection programs, hardware replacement, and load-testing to keep your system performing to spec season after season.

Engineering Mindset

The structure above the stage is not a place for improvisation.

Every rigging point YKCA installs is load-rated to manufacturer specification. Every motor is matched to the structure it attaches to. Every cable run and branch circuit powering overhead equipment is designed and installed under our C-10 license — so one team is accountable for the whole overhead system from the steel to the service panel.

Third-party inspected where the project scope requires it.

FAQ

Rigging questions, straight answers.

Every rigging project starts with a load assessment. We calculate the combined weight of truss, fixtures, cables, and dynamic loading, then design the system so every component — from the motor to the attachment point — is rated to manufacturer spec with appropriate safety margin. For larger or more complex installs we bring in a licensed structural engineer to review and stamp the design.

Motorized chain hoists make sense when positions need to change between shows, when trim heights must be precisely repeatable, or when flying scenery or large lighting rigs is part of the production. Fixed grids and pipe-and-base structures suit venues where layout is static and budget or structure limits permanent installation. We assess your programming needs, building structure, and budget and recommend the system that makes operational sense — not the more expensive option by default.

Often yes, but it depends on what is above the ceiling. We inspect the existing structure — steel, wood, or concrete — verify load paths, and determine whether new attachment points are feasible and at what capacity. Where the building structure is insufficient for the intended load, we design supplemental steel or redirect loads to appropriate members. We do not attach rigging to structure that has not been assessed.

Annual inspection is standard practice for permanent rigging systems. High-frequency venues — those running multiple productions per month — benefit from a mid-year visual inspection as well. After any significant impact, overload event, or building work near attachment points, an out-of-cycle inspection is warranted. We offer maintenance contracts and can schedule inspections on a cadence that matches your production calendar.

Permit requirements vary by jurisdiction and project scope. Structural modifications — new attachment points, supplemental steel — typically require a building permit and engineering. The electrical side of motorized hoists (power distribution, motor branch circuits, control wiring) always falls under our C-10 license and requires an electrical permit. We determine the full permit scope on every project and handle the filings; we do not ask the venue to manage their own permits.

From a single truss span to a full overhead grid — we scope the structure, the motors, and the power as one project, then build it.
