Illustrative scenario: this describes a generic UK third-party logistics operation, not a named client. Nothing here is a measured client result, and every figure is a typical engineering range.
In short: an autonomous forklift 3PL short contract UK deployment is normally hired or leased rather than bought, built from robot classes that need no fixed infrastructure, and connected to the client WMS through a light integration layer. It is specified from the first day so it can be de-rigged and moved when the contract ends.
The operation
A regional third-party logistics operator running shared-user and dedicated storage from one site, handling ambient palletised goods for a mix of retail and FMCG clients. The bands below are where this kind of operation usually sits.
- Sector: third-party logistics, ambient palletised stock, with case picking and roll cage work for store deliveries.
- Scale band: typically 10,000 to 40,000 sq m under one roof, with in the region of 8,000 to 25,000 pallet positions across wide aisle and narrow aisle blocks.
- Shift pattern: typically two or three shifts across 5 to 7 days, goods in weighted to the early shift and despatch weighted to the late one.
- Throughput band: typically in the region of 300 to 1,200 pallet moves a shift, rising and falling with the client mix.
- Contract length: commonly 12 to 36 months, with break clauses and volume bands that can be reset inside a quarter.
- Building: usually leased, often with landlord limits on drilling and permanent fixtures.
At a glance: typical application snapshot
Capability ranges for the robot classes that normally suit this application. The actual specification follows the site survey.
- Robot classes, typical: autonomous counterbalance and reach trucks for pallet work, plus AMRs for roll cages, totes and trolley trains.
- Payload, typical: in the region of 1,000 to 2,000 kg for the pallet classes and 200 to 1,000 kg for the AMR classes.
- Lift height, typical: 1.6 to 11 m depending on class and mast.
- Aisle width, typical: 2.7 to 3.5 m for reach classes in standard racking, tighter where a very narrow aisle class is used.
- Travel speed, typical: 1.2 to 2 m/s laden, slowing automatically at junctions and in zones shared with people.
- Runtime, typical: 6 to 10 hours between opportunity charges, with charge windows in the region of 10 to 30 minutes taken in natural breaks.
- Navigation, typical: natural feature and laser navigation, so no buried wire, floor magnet or reflector grid is left in the landlord building.
- Mobilisation window, typical: 6 to 12 weeks from contract award to live running on an existing site.
The challenge: asset life in years, contract life in months
For a third-party logistics operator the hard part of automation is rarely the engineering. It is the mismatch between an asset specified for a working life measured in years and a client contract measured in months. Four pressures show up on almost every shared-user site.
- The commitment is longer than the certainty. Signing a capital purchase against a contract with a break clause at 12 or 18 months puts the risk in the wrong place.
- Every client brings its own systems. One contract runs a tier one WMS, the next runs a client hosted system with a thin interface, the third sends flat files overnight. The fleet has to speak to all of them.
- Mobilisation is short. Award to go live is often 6 to 12 weeks, which rules out anything needing structural work, long lead items or a floor that has to be relaid.
- Volume is not flat. Shared-user sites absorb seasonal peaks, promotions and client gains and losses, so a fixed installation sized for the busiest week sits idle for much of the year.
A single vendor ecosystem built on proprietary infrastructure makes each of these worse, tying the operator to one maker for the life of the building rather than the life of the contract.
Autonomous forklift 3PL short contract UK: how the solution is normally specified
As the UK partner of SEER Robotics and a integrator, FlyWei specifies the robot class against the task rather than the badge. On a multi-client site that usually means a mixed fleet drawn from several manufacturers, working together under one fleet layer.
- Pallet movement. Autonomous counterbalance trucks for trailer to floor and floor to rack moves, reach classes for put-away and replenishment into racking. These are standard autonomous forklifts rather than bespoke machines, so a unit can move to another contract without being rebuilt.
- Cage, tote and trolley movement. AMRs for roll cage trunking to marshalling, tote feeds to pick stations and goods-to-person work where a client contract needs it.
- Infrastructure-free navigation. Natural feature navigation keeps the building as the landlord expects it and keeps the de-rig at contract end short and clean.
- One fleet layer over several makes. Traffic control, task allocation and charging are handled above the individual robots, so adding a different manufacturer for a new task does not mean a second control room.
- Connecting to what the client already runs. The fleet layer takes tasks from the WMS, ERP or line PLC already in place. Where a client system has a modern interface that is a direct connection. Where it does not, the integration works from scheduled files, label and barcode events or a middleware layer, so the client is not asked to change their system for your contract.
- A commercial shape that matches the contract. Buying outright suits a long dedicated contract. For shorter terms, leasing or hire lines the cost up with the revenue it supports, and units can be returned, extended or moved as the contract changes.
The same thinking is set out across our logistics and warehousing solutions, where multi-client flows and changing client systems are the normal case rather than the exception.
How a deployment runs
- Free site survey. We walk the site, measure aisles, floor condition, dock constraints, charging positions and the zones people share with trucks, and record the client systems in play.
- Simulation. Move data from the WMS is used to model the flows, size the fleet honestly against the busiest realistic shift and find the pinch points before anything is ordered.
- Phased rollout with a parallel run. One flow goes first, typically put-away or replenishment. Manual trucks keep running the same flow alongside the robots until the handover is proved on real volume.
- Live operation. The flow is handed over, operators are trained on the fleet interface and exception handling, and service and support cover is set against the shift pattern.
- Scale-up or move. Further flows are added as they earn their place. At contract end the fleet is de-rigged, re-surveyed for the next site and recommissioned there.
Typical results
Results depend on the site, so we describe the direction of travel rather than invent figures.
- Repetitive trunking and put-away moves run through quiet periods and night hours without extra supervision.
- Trained truck drivers move to work that needs judgement: inbound checks, quality, exception picking and client facing tasks.
- Pallet locations stay closer to what the WMS believes, because the move and the system update happen as one event.
- Peaks are absorbed by adding hired units for a season rather than recruiting against a short, uncertain window.
- When a contract ends the automation leaves with it, so the next client is quoted on capability, not on stranded assets.
What to consider for your site
- How long is the contract, and where are the break clauses and volume bands?
- Is the floor flat enough and the racking square enough for automated put-away at height, or is remedial work needed first?
- What does the client WMS expose, and who owns the integration if the client changes system mid-contract?
- Does the lease allow any fixed installation, and what does the building have to look like when you hand it back?
- Which single flow, if automated first, would prove the case fastest on real volume?
- Where will robots and people share aisles, and how are those zones marked and controlled?
- Does the commercial model let you return, extend or move units when the contract moves?
Next step
If you are weighing automation against a contract that may be resized or renewed, the useful first step is a survey of the real site rather than a generic proposal. Book a free site survey and we will walk your flows, look at the client systems involved and say plainly which moves are worth automating inside this contract term.
