Corridor work is sold by the kilometre at a specified clearance, and the client is buying the absence of incidents as much as the vegetation removed. An outage on a distribution feeder, a rail possession that overruns, or a lane closure extended by an hour costs the asset owner more than the day's clearing is worth — which is why precision, load control and predictability are priced above throughput in this package.
The fleet is built around reach from a permitted standing position rather than around cutting capacity. On established corridors the machine frequently cannot stand where the vegetation is, so the reach requirement is set by access rules and not by the trees, and a machine specified against the vegetation alone will be short.
The commercial advantage is diversification. The same capability serves electricity networks, rail, road authorities, councils, mining, pipelines, renewable-energy developers and fire-management agencies, each on a different procurement cycle. Contractors serving several are rarely idle across all of them at once.
Every fleet produces at the rate of its slowest element and pays for all of them. This is where that element usually sits in this package.
Each one has an answer specific to your sites. A default taken from someone else's operation is where imbalance starts.
8-15 tonnes is the common range: enough boom and lift for controlled removal, small enough to work road shoulders and easements and to move between spans without a specialised float. Larger carriers gain reach and lose the mobility that corridor work depends on.
Permitted standing position to the vegetation, plus the specified clearance envelope, at a geometry where the lift chart still supports the limb weight. All three terms matter; specifying from the first alone is the standard error.
Grapple saw near live assets, because the limb is held through the cut and placed deliberately — which is the outcome the client is paying for. Shears away from assets where material can fall freely, for speed and simplicity. Many fleets carry both and choose per job.
Wherever the residue has to leave the corridor. Where mulching in place satisfies the specification, the chipper and its truck cycle come out of the fleet entirely — which is a substantial cost difference and should be settled with the client before pricing.
The package above assumes a typical case. These are the departures that change the configuration rather than just the rate.
Very few contractors start at the full configuration, and the ones who do are usually carrying more capital than their contracted work supports.
Phase 1
One carrier with a mulcher or grapple saw, working to an established vegetation contractor.
Phase 2
Two carriers covering mulching and controlled removal, plus traffic management capability.
Phase 3
Mulchers, grapple saws, chippers, stump grinders and a remote-controlled carrier for restricted ground.
Cutting capacity is the headline on every attachment brochure and is almost never the binding constraint near live assets. The lift chart at working reach decides whether the job can be done at all.
Permitted standing positions on rail formations, road shoulders and easements are controlled, and can be metres further from the vegetation than the site suggests. A reach specification built on an assumption is discovered on the first job.
A single network contract can support a fleet until the panel is retendered. A fleet that cannot pivot to council, mining or renewables work carries the full retender risk on its finance schedule.
Utility and rail prequalification carries real recurring cost in systems, training and audit. It is a cost of direct work and belongs in the model before leaving subcontracting.
Grips before it cuts, and keeps control of the severed section — the attachment for working near assets.
Turns an existing excavator into a dedicated pruning platform — no second carrier required.
The strongest crossover market in Australian forestry — plantations, councils, utilities, mining, solar and fire.
Sits between harvesting and biomass markets — and starves without a properly engineered feed system.
