We keep records of every repair that comes across the bench, by failure mode. Over five years the top line has never moved: lead board crack or loss, forty-one percent. The outermost deck board at each end of the platform is the single most replaced component in the industry.
Everyone assumes this is operator error, and some of it is. But when we go on site and watch, the pattern is usually mechanical and usually fixable in an afternoon.
The lip
A dock plate or leveller that sits even a quarter-inch above the trailer floor creates a step. The forklift tines rise over that step and come down onto the pallet's lead board rather than entering cleanly beneath it. Every single entry hammers the same board. Multiply by a hundred movements a day.
The gap
The opposite problem. Too much space between plate and trailer and the tine tip drops, catching the bottom lead board on the way in. This one tends to break boards rather than crush them, and it leaves a characteristic splintered end that we can identify from across the shed.
The crown
Older levellers develop a crown in the middle from decades of load. The tines follow the crown, rise, and strike the top deck. If your lead board damage is concentrated on the top deck rather than the bottom, look at the plate profile with a straight edge.
The approach angle
Where a trailer parks on a slope, or the apron has settled, the plate sits at an angle the operator cannot see. They aim at the opening and hit the board. Nobody is doing anything wrong; the geometry is simply lying to them.
Diagnosing it in thirty minutes
- Stand beside the dock, at tine height, and watch twenty entries. Do not tell the operators why — you want normal behaviour.
- Note whether damage is on the top or bottom lead board. Top suggests a rise, bottom suggests a drop.
- Lay a four-foot straight edge across the plate and look for a crown or a dip.
- Measure the step between plate and trailer floor with a tape, loaded and unloaded. Trailers settle when they take weight.
- Check whether your chamfered bottom boards are actually chamfered. An unchamfered bottom deck turns a small step into a snag.
The cheap fixes, in order of return
Grind or shim the lip. Specify chamfered bottom boards on your next order — it is pennies and it lets a tine or a jack wheel climb aboard instead of catching. Put thirty minutes of coaching into fork entry for new operators, specifically on aiming low and entering level. Replace a crowned leveller when it is due, not when it fails.
We make money repairing lead boards. We would still rather you fixed your dock plate, because the customers who do are the ones still buying from us a decade later.
What the damage pattern tells you, in detail
A lead board does not just break. It breaks in a way that identifies its cause, and once you have seen a few thousand you can read them from across a shed. This is genuinely useful, because it lets you diagnose a dock from a photograph.
- Crushed, fibres compressed downward, no splinters. A tine or wheel came down on top of the board. Look for a step the forklift is climbing — plate lip, settled apron, or a trailer that drops when it takes load.
- Splintered end, fibres torn outward. Something entered under the board and levered up. Usually a tine tip dropping into the gap between plate and trailer floor.
- Clean break across the board at a nail line. Not a dock problem. That is a fastener pattern running parallel to the grain, splitting along the perforation.
- Damage concentrated on the top deck rather than the bottom. Suspect a crowned leveller. Lay a straight edge on it.
- Damage on one end only, consistently. Somebody has a habit, or one specific dock door has a problem the others do not. Both are fixable in an afternoon.
The cost of not fixing it, for a mid-sized dock
A site moving 1,200 platforms a month with a lead board failure rate of 4% is retiring or repairing around 576 platforms a year to a single cause. Whether you absorb that as replacement purchases, as repair charges from us, or as damage claims when a board fails in transit, it is a four-figure annual number driven by a quarter-inch step in a piece of steel.
We have had this conversation with customers who then spent an afternoon with a grinder and a shim and cut the rate by more than half. The ones who did not are still buying more pallets from us, which is a strange thing for us to be complaining about and we are complaining about it anyway.
One thing to specify on your next order
Chamfered bottom deck boards. An angled edge lets a tine or a jack wheel climb aboard instead of catching on a square corner. It costs a fraction of a cent per board, it is omitted from most economy builds, and on a dock with a step it is the difference between a snag and a broken board on every single entry.
