Two Autonomous Forklifts for a Lumberyard: Install, Charging, Training

What does a lumberyard need before two autonomous forklifts start work?

A lumberyard that plans to run two autonomous forklifts this quarter needs three things ready before the first machine arrives: a yard route the machines can map and follow, a charging spot with the electrical capacity to support two units, and a training plan for the people who will work beside them. Install is mostly about the route and the docks. Charging is electrical work that starts long before delivery. Training is the piece most often left until the final week, which is the wrong order.

Your volume sets the stakes. Two hundred trucks a week across three docks is about 67 trucks per dock each week, so the route between the stacks and the doors is the first thing to get right. A blocked or unmapped stretch slows every dock that depends on it, and one bad route can hold up all three.

Is the yard floor and travel route ready for autonomous forklifts?

The first question for install is the ground. Autonomous forklifts need a surface that stays consistent, so a yard that is mostly gravel, deep mud or heavily rutted will need paving or grading along the routes before any machine can run reliably. Drainage matters for the same reason. Wet or icy ground changes how a truck brakes and turns, so ask the integrator for the surface limits in writing and note where water pools after rain.

Second, the route itself. Map where stacks will sit, where trucks park at each dock, and where people walk. A lumberyard often changes its stack layout as orders come in, so a route that is clear on survey day may be blocked by the end of the week. The site assessment should record which lanes stay fixed, which lanes move, and where pedestrians cross. Painted lane edges and steady lighting after dark help the machines and the people beside them.

Third, the docks. Trailers do not always park in the same spot, and that changes the pick-up and drop-off zone. If trailer positions vary widely, the robot may need staged pick-up points and staff to set trailers, and that limits how much of the dock work the machines can take on.

What injury risk do forklift yards and wood plants carry?

Forklift work carries real risk, so the safety case for a robot starts with the hazard. According to OSHA's Region I directive on powered industrial trucks, about 1.5 million workers operate roughly 855,900 powered industrial trucks, and the directive cites about 85 forklift fatalities and 34,900 serious injuries a year. Those are older estimates from a 2017 directive, so read them as the scale of the problem and not as a current count.

Wood industries report high rates in state data. South Carolina's BLS-based injury table lists an incidence rate of 3.6 for wood product manufacturing in 2023 and again in 2024, and 3.7 for sawmills and wood preservation in 2023. The 2024 sawmill figure in that table carries a footnote marker the source summary could not interpret, so this page does not use it. For the national picture, according to Safety and Health magazine, employers reported 2.5 million injury and illness cases in 2024, down 3.1% from 2023, and the private industry total recordable rate was 2.3 per 100 full-time workers, down from 2.4.

A state incidence rate and a national total recordable rate are not the same measure, so compare the direction of change more than the decimals. What the numbers do show is that wood work carries injury rates that deserve a plan of its own, and that mapping, separation of people from machines, and training carry more of the safety case than the robot does.

How much electrical work does charging need?

Charging is where many installs stall, because it depends on the building's electrical service as much as on the robot. A charging vendor's guide calls for an electrical load study before any charger goes in, planning for peak simultaneous use, circuit protection, a clear emergency shutdown procedure, and training on charger alarms. Those steps are guidance, not a code. No specific code or standard for autonomous forklift charging areas turned up in the research, so your electrician and local inspector will set the final rules.

A forklift maker's electrification FAQ says charger placement depends on operators, facility layout and electrical infrastructure, that upgrades are not always needed, and that working with the utility provider is recommended. The same FAQ says lithium packs stay in the truck while charging, which allows rapid charging and can support a 1:1 charger-to-forklift ratio. That ratio is a vendor-reported claim, but it is a useful planning case. Two forklifts at a 1:1 ratio mean two charging points, each with its own circuit and protection.

Connector design belongs in the same conversation. Automated charging can use contact arrangements that differ from a manual plug, so the bay layout should follow the chosen machine rather than come first. Ask for the charger input requirements of the specific unit before the site walk, so the electrician can plan against real numbers.

What training do operators and nearby staff need?

OSHA's powered industrial truck standard, 29 CFR 1910.178, requires operator training and periodic evaluation. Autonomous units do not remove that requirement for the human-driven trucks still working in the yard, and they add a second group that must be trained: the staff who walk, load or stage material near the machines. Those staff need to know the lanes, the stop procedure, what each alarm means and what to do when a machine halts in the middle of a route.

Staff turnover turns training into a recurring cost. A warehouse workforce summary cites a 49% turnover figure for US warehouse workers, attributed to 2023 BLS data, though the original BLS table was not located. A survey-based average of 11.6% across warehouse and distribution operations is also reported, with no survey date given. Neither figure is a lumberyard number, so pull your own HR records for the real rate and set refresher sessions around it.

Plan training for three groups: the operators who run or supervise the machines, the floor staff who work near them, and the shift lead who responds to alarms. Each group needs a separate level of detail. The group most often missed is the one that stages trailers at the dock, because those workers are not thought of as working near the machines until a near miss happens.

How does the work change for your staff with two autonomous forklifts?

Autonomous forklifts take over repeated moves inside a fixed route. That frees people for tasks that need judgment, such as checking loads, sorting stock and coordinating with drivers. They do not close a staffing gap on their own, because someone still sets up the route, responds to alarms and manages charging. The comparison below sets out the work as it runs today and as it would run with the machines in place.

The honest test is the worst day, not the average one. If stacks and trailers change daily, plan for staff to reset the route at shift start, and count that reset time as part of the robot's workload rather than as free time.

When is an autonomous forklift not the right fit for a lumberyard?

The robot is not the right fit if the yard is largely unpaved and cannot be graded, if stack positions change so often that no map holds through a shift, or if most dock work is hand-set loads at irregular trailer positions. In those cases the budget may stretch further in paved zones with conventional equipment and extra trained staff. Say so during the site assessment. A robot pushed into the wrong yard will spend its early months fighting the ground and the stacks.

It is also a poor fit if you need full volume on day one. A phased start with one unit on one route, a longer training window and a backup plan usually works better than putting both machines on the busiest dock at once. Starting with one leased unit lets the yard prove the route before the second machine arrives.

How do the lease, deployment and service work after the site assessment?

We start with a free site assessment. We map the route, check the surface and drainage, look at the docks, and document where charging could go and what the electrical side needs. The lease is quoted only after that assessment, because the route and charging needs decide the unit count and the layout. Once the quote is accepted, the robots are leased through financing, so the yard does not have to pay for the machines up front.

We pick the robot to fit the yard, not the other way around, because we are OEM-neutral and work across manufacturers. We deploy and integrate the units, train the operators and floor staff, and service every unit under our service plan, with regional service engineers in every state we service. One partner handles the lifecycle, so you have one number to call when a unit stops.

What should the site have ready on install day?

Confirm each item below before the first machine rolls in. Each one either changes the install schedule or changes the answer on whether the yard is ready at all.

Set the install date after the electrical study and the route sign-off, not before. The usual failure is a delivery date set by the calendar rather than by the yard, and that is the easiest mistake to avoid.
