What a fly system inspection covers

The whole line set.
Not only the deck.

A fly system inspection goes the full height of the tower - from the rope lock you reach from the floor to the head and loft sheaves you do not. Here are the four component groups we check on every line set, against published discard criteria.

Not sure when your tower was last inspected, or how many line sets you are running? and we will scope it to your tower.

What a fly system inspection is

Every set,
checked top to bottom.

A scoped examination of your counterweight flying system, carried out in-house by TSA's Competent Inspection Officers. It is the depth a busy fly tower needs between whole-of-venue Venue Systems Health Checks. Every component gets a compliance result against published discard criteria, and every defect is graded, with a recommended action and a rectification timeframe:

50+ standards assessed against 80+ line sets handled Priority graded defects Timeframed rectifications 12 mo chain-hoist certs

What we inspect

The whole line set,
graded and dated.

We work the line set from the rope lock to the loft. Every component is assessed against its discard criteria, every defect is graded on priority, and each finding carries a recommended action with a rectification timeframe.

Battens & trim chainsThe load-carrying bar and its trim chains - checked for straightness, security and even trim.Graded
Counterweight cradles & guidesCradle frames, weight stacks, locking pins and guides - wear, deformation and balance.Graded
Hauling linesThe operating line that drives the set - condition, splices and terminations.Graded
Loft wiresThe wires carrying the batten - checked along their length and at the pick-up points.Graded
Wire ropes & terminationsAssessed against the wire-rope and termination standards for broken wires, corrosion and swage condition.Graded
Head & loft sheavesGroove wear, bearing condition and true running on the head and loft sheaves.Graded
Rope locksGrip, security and adjustment on the part that holds a set where you leave it - the focal check.Graded
Fleet angleThe lead-off angle from sheave to drum or cradle - checked so lines track without rubbing.Graded

A scoped inspection, in the depth a fly tower needs.

Each component carries a compliance result against discard criteria, and every defect is graded on priority with a recommended action and rectification timeframe - the graded record of your whole flying system, line by line.

Or audit the whole venue

A fly system inspection goes deep on the flying system; the Venue Systems Health Check covers all your stage systems, and the Service & Inspection Programme keeps them current with scheduled visits and a documented history. Either way, every electric chain hoist inspected is load-tested and certified for 12 months. If you want the background first, our guide to theatre fly systems walks through the line set and what the inspection grades.
